  • Volume 21 Persistent endodontic infection - re-treatment or surgery'
    • Abstract: Love, Robert M Management of a tooth with persistent periradicular disease primarily involves management of persistent intraradicular infection. Conventional endodontic re-treatment is the main modality that will manage this condition although endodontic surgery with or without retreatment is a viable option in cases. Case selection involves an appreciation of the disease aetiology and expected outcomes and consideration of patient, tooth and clinician factors. Both conventional endodontic re-treatment and surgery have high long-term success and survival rates and it has been shown that an endodontically treated tooth with persistent periradicular pathology that can be managed by conventional endodontic re-treatment or surgery and restoration has comparable, and potentially more beneficial, outcomes to treatment options involving tooth loss and rehabilitation, such as an implant supported crown. As such endodontic retreatment should be the prime treatment modality unless a tooth has reached a stage where these techniques cannot manage ongoing disease and/or structural integrity.

  • Volume 21 Resin infiltration- taking the first steps to filling the holes
           in cheese molars
    • Abstract: Kumar, Harleen; Palamara, Joseph; Burrow, Michael F; Manton, David J Molar incisor hypomineralization (MIH) involves enamel hypomineralization of systemic origin affecting one or more first permanent molars (FPM) and is often associated with other teeth, particularly the incisors. A challenging condition for both the clinician and the patient, MIH affected teeth are often subjected to repeated treatments and frequently the decision to extract one or more FPM is made. At present, there are no clinical reports of available restorative materials that are able to provide consistently adequate restorations on hypomineralized teeth. The concept of resin infiltration, which involves occluding incipient enamel carious lesions with low viscosity resins to arrest or slow the development of caries has the potential to be applied to hypomineralized enamel. Successful penetration of resin infiltrant into MIH affected enamel may aid in improving its micromechanical properties.

  • Volume 21 The application of skeletal anchorage in the correction of
           anterior open bite and skeletal class iii malocclusion: A paradigm shift
    • Abstract: Tarraf, Nour Eldin In recent years orthodontic treatment has been revolutionized by the introduction of skeletal anchorage or temporary anchorage devices (TADs). Many malocclusions, which have been previously only treatable through orthognathic surgery, such as skeletal open-bites, can now be managed non-surgically with less biological cost to the patient. Furthermore the recent application of TADs in the treatment of growing skeletal Class III patients is not only minimizing the need for obtrusive appliances, such as head gear and face masks, but it is also proving to deliver better and superior results to conventional growth modification protocols with more patient acceptance and less need for compliance. This overview covers the applications of TADs in the treatment of skeletal open bites and skeletal Class III malocclusions with reference to current evidence and clinical case presentations.

  • Volume 21 The impacted canine - an orthodontic perspective
    • Abstract: Madsen, David P The impacted canine is relatively common in incidence and can often lead to difficult treatment planning decisions. Cone Beam Computed Tomography (CBCT) imaging has improved diagnosis and treatment planning of impacted canines. In particular, this technology has allowed the clinician to accurately locate and visualize these teeth better than ever before, as well as greater appreciate the degree of damage to neighbouring teeth such as lateral incisors. Improved diagnosis and treatment planning with CBCT has therefore resulted in improved treatment outcomes. The objective of this presentation will be to cover the incidence, complications and management of impacted canines from an orthodontic perspective. Impacted canines are commonly cited as occurring in 1% of the population. Complications of impacted canines include root resorption and devitalization of the adjacent lateral incisor, ankylosis, cyst formation and prolonged retention of the deciduous canine. Interceptive management of impacted canines may include the removal of the deciduous canine. Management of impacted canines also include either their removal or orthodontic movement into their correct position.

  • Volume 21 Implant complications: Risk evaluation, diagnosis, management
           and outcomes
    • Abstract: Peake, Gregory G Dental implants and their restorations have become an accepted and predictable modality of treatment. The literature reflects excellent long-term survival rates. However, survival of an implant does not necessarily translate to success, and in between these two outcomes lies the world of implant complications. Complications associated with dental implants occur with both the restorative and surgical components, with the restorative component complications being more frequent and to some extent, more easily managed. Surgical complications are difficult to manage, and can be the result of many aspects of the implant surgery. Potential complications can arise from poor planning, poor case selection, and poor execution. Complications can also occur where no technical or surgical errors are apparent, but where biology and the fundamental fl aw of the trans-mucosal design of dental implant prostheses, adversely affects the outcome. This presentation outlines the nature of potential complications and looks at practical and pragmatic methods, first to try to prevent complications, through improved case selection and execution; secondly, it discusses the most effective methods to prevent complications in implants already installed, by adequate maintenance programmes. Lastly, it deals with those cases which require clinical management of the complications. This presentation provides the clinician with a greater understanding of the difficulties in managing implants that are not progressing as we, the clinicians, and the patients, had originally expected.

  • Volume 21 Timing of implant placement: Planning and procedures for
           predictable clinical and aesthetic outcomes
    • Abstract: Danesh-Meyer, Michael The placement of dental implants is dependent on a number of factors relating to both the patient and the site in which implant placement is contemplated. Additionally, there has been a general trend towards immediacy in implant therapy. This paper considers case selection and clinical decision-making and treatment guidelines in cases where immediate implant placement is contemplated. Treatment alternatives, including site preservation, early and delayed implant placement are also discussed.

  • Volume 21 Endodontic assessment: Pulps, pain and prognosis
    • Abstract: Abbott, Paul V Pulp, root canal and periapical conditions are the most common reasons for patients to present to dentists for emergency or urgent management. These conditions will be either inflammatory in nature or due to infections, with infections also causing inflamed tissues. In order to accurately diagnose such conditions and to then manage them appropriately, it is essential that dentists have a thorough knowledge and understanding of the various conditions that affect the pulp, the root canal system and the periapical tissues. Traditionally, many dentists have used vague and misleading terms to indicate pulp diseases - such as ' vital' and 'nonvital' pulps. However, these terms are very inaccurate and meaningless as they do not accurately indicate the state of the pulp (only the presence or absence of blood supply) and they do not indicate the management options. For example, the pulp of a tooth that responds to pulp sensibility tests and is therefore designated as 'vital' could have any one of 12 different conditions if a more comprehensive diagnostic classification is used. These 12 conditions require different management - such as no treatment (e.g., for a clinically normal pulp), caries removal or restoration replacement (e.g., for acute reversible pulpitis), root canal treatment (e.g., for acute irreversible pulpitis) or extraction (where the tooth is not suitable for further restoration). Similarly, a tooth that does not respond to pulp sensibility testing and was previously designated as 'non-vital' could have any one of 10 different pulp or root canal conditions which require different management. In addition to considering the pulp and root canal conditions, the diagnosis must also include assessment of the periapical tissues, ideally also using a comprehensive diagnostic classification that includes all of the possible tissue changes that can occur throughout the life of a tooth. Overall, there are 17 different pulp/root canal conditions and 14 different periapical conditions in these two classifications. When diagnosing any tooth, both tissues must be considered (because the state of the pulp/ canal determines the periapical condition) and therefore there are many permutations and combinations that must be considered.

  • Volume 21 Attrition and erosion: Restorative planning and performance
    • Abstract: Burrow, Michael F The number of patients presenting with severe attrition and associated erosion is increasing in frequency. Treatment of this patient group is very challenging as it is simply not just a case of replacing lost tooth tissue, but also trying to identify and then eliminate the aetiological factors responsible for the loss of tooth structure. In most cases restorative treatment involves extensive rehabilitation of the dentition to restore the aesthetics and function and also to prevent further tooth loss. Such treatment often involves a multidisciplinary approach to eliminate and/or reduce causative factors prior to definitive restoration of teeth. Treatment needs to focus on quick intervention when the problem has been identified and diagnosed. Restorative treatment involves careful if not complex planning culminating in the establishment of a well defined and ongoing maintenance plan. Long-term success of treatment is centred on the maintenance phase. Current restorative options include the use of extensive resin composite build-ups. This is often the best initial starting point as it allows for adjustments, as well as being a reversible and more conservative procedure. The use of indirect restorations is likely to provide a longer lasting outcome after initial stabilization, whether it is metal- or ceramic-based or a combination.

  • Volume 21 Attrition and erosion: Assessment and diagnosis
    • Abstract: Meyers, Ian The management of patients with extensively worn and badly broken down dentitions presents a difficult challenge in dental practice and restorative treatments are often complex, time consuming and costly to implement, so careful case selection and treatment planning is essential. Ultimately the success of any restorative intervention is very dependent on the stability of the oral environment and the status of the remaining tooth structure. Prior to the commencement of any restorative treatment an understanding of the importance of the disease process, the risk factors in the mouth, and the intrinsic and extrinsic factors which affect the oral balance is critical. While there is a growing range of materials and techniques available for cost effective and conservative management of these cases, failure to take a systematic approach to assessment and stabilization may result in early restorative failure, rapid recurrence of the problems and a repeat restoration cycle. Therefore successful management of these patients must include an appropriate mix of preventive and restorative strategies.

  • Volume 21 Adverse drug reactions: Oral and dental manifestations and
           complications
    • Abstract: Schifter, M Adverse, that is unintended untoward effects of medications, are increasing in incidence and their severity, given the aging of the Australian and New Zealand population and associated drug use. Not only are the number of agents that our patients are using increasing, including the increased use of "alternate" or "complimentary" medications, but also their complexity, with the advent of potent, targeted, biological agents. The result is an increasing number of our patients will be at greater risk of adverse effects from their medications. These adverse effects include the impeding of the safe delivery of dental treatment and the adverse oral and dental manifestations and complications related to the use of medications.

  • Volume 21 Non-prescription medications: Considerations for the dental
           practitioner
    • Abstract: Kingon, Angus The widespread availability of non-prescription medications has a significant potential impact on dental practice. Dentists are trained to provide scientifically-based advice on the appropriate use of medications, but it is not uncommon for patients to take matters into their own hands, especially if it is felt that the treatment provided is not solving a specific problem, or is insufficient. Well-meaning but often ill-informed family and friends frequently have an opinion as to what should be done. Not only may the suggested treatment not be effective, it may also be harmful. Over-the-counter medications can easily be obtained, and there is nothing to stop individuals exceeding recommended doses, and if this occurs, there could be adverse medical sequelae. Patient compliance in taking prescription medications is known to be problematic, and when combined with the ready availability of complementary medications, probiotics and illicit drugs, the risk of self-harm can be seen to be a distinct possibility. To compound the position, sometimes there seems to be, in a practical sense, little regulation on the advertising and marketing of non-prescription medications, which can leave consumers not only confused but potentially vulnerable. While complementary medicines may not have a significant role in dental practice in 2012, that may not always be the case as research continues, and reference is made to some aspects of ongoing work. Non-prescription medications are discussed, and some effects on oral health are considered.

  • Volume 21 The role of the dentist in the management of systemic conditions
    • Abstract: Cullinan, Mary The rates of lifestyle-related diseases are increasing. Worldwide there is an obesity epidemic, one of the consequences of which is an overwhelming increase in type 2 diabetes, not only in adults, but also in children and adolescents. Many cases are currently undiagnosed resulting in serious complications and placing individuals at increased risk for cardiovascular disease. As many diseases share common risk factors, the current emphasis is on primary prevention and risk assessment by all health care providers to enable detection and early intervention. Lifestyle factors that impact on oral health can also have an impact on general health, and lifestyle behaviours that promote better oral health can decrease the risk for chronic disease. In this context, changing oral health behaviour to promote better oral health may directly impact on improving general health for all age groups. Risk assessment for systemic diseases in the dental setting is explored to provide dental professionals with a framework for promoting better overall health for their patients.

  • Volume 21 Periodontal treatment and systemic conditions
    • Abstract: Ivanovski, Saso It has been reported that patients with periodontal disease have a greater prevalence of systemic disease than the general population. Furthermore, we are faced with an ageing population that is retaining its teeth for longer, and tends to present for periodontal management with a variety of systemic conditions. There is ample evidence to show that periodontal treatment results in a systemic response, which includes bacteraemia and systemic inflammatory cytokine release. Certain systemic conditions present unique challenges in the treatment of periodontal disease. These conditions include cardiovascular disease, diabetes mellitus and cancer. The various treatment modalities for these systemic diseases can impact on periodontal treatment, and conversely periodontal treatment can influence systemic conditions and their management. Close collaboration with the treating physician and timely provision of periodontal treatment are important considerations of managing the systemically compromised patient.

  • Volume 21 Workforce education - the co-ordination of oral health care for
           the elderly - the role of the dental profession
    • Abstract: Borromeo, Gelsomina L It is a well-understood fact that the world's population is ageing. Concomitant with that is an increase in the chronicity of disease including dental disease. The challenges faced by the dental profession in managing patients as they age are becoming increasingly important. What do we know and understand about diseases and their impact on dental health in the elderly' What role do salivary dysfunction and biofilms play and how are these integrated with general and oral health' Are we really prepared to manage the impact of these factors and what is the profession doing to better equip itself for the inevitable change to dental practice that is likely to ensue' Dental education in Special Needs Dentistry and in particular geriatric care expands beyond the realms of the University setting. There is potential to expand knowledge in dental care amongst the elderly through continuing professional development that is now mandatory across Australia and New Zealand. Training should not be limited to University curricula. It should extend to include medical and allied health staff, staff in aged care facilities and all those involved in policy and decision making for the elderly.

  • Volume 21 Informed consent, dementia and oral health care provision
    • Abstract: Ting, Graeme Managing patients with dementia requires a practitioner to exercise diverse skills. Communicating with the patient (as their dementia allows), relatives, caregivers and medical personnel are essential elements in the care process. Diagnosis of oral health problems may not be straightforward, clinical examination and treatment planning may be hampered by poor cooperation from the person with dementia. Practitioners must view any treatment from the patient's perspective and balance this with the requirements for sound clinical care. The consent process must be approached in a manner that fulfils the 0thical responsibilities that acknowledge patient rights. This can be difficult when managing a patient with dementia. This paper will explore issues surrounding the consent process and the provision of oral health care to people suffering from dementia. It is hoped that readers will be stimulated to review their practice; especially related to informed consent, whether they routinely manage patients with dementia or not. Such practice evaluation should consider the wants and needs of patients and families on a broader than clinical basis and thus enhance the care that is brought to this group of interesting and often challenging patients.

    • Abstract: Shnider, Warren Geriatric healthcare has already changed. We are living longer and we are enduring those additional years with more severe chronic disease and a greater number of chronic diseases. Current mechanisms to improve oral health care for individuals and the community are considered in this paper. We are still yet to measure the effectiveness of these changes. Even more complex is the confusion and conjecture about what we should be measuring and whether what we measure actually has an impact on the quality of life.

  • Volume 21 Obstructive sleep apnoea: Investigations, diagnostic techniques
           and predicting surgical success
    • Abstract: Gillingham, Wayne Obstructive sleep apnoea (OSA) is diagnosed using a sleep study or Polysomnogram. The paper discusses the role of imaging and other examination techniques to assess the nature of OSA and what treatment you can offer a patient. When should a patient be offered a mandibular advancement splint' What type should be used' How do we know it is working' Surgical treatment of OSA is a controversial area. This paper provides an understanding of which patients may benefi t from surgery and when is an appropriate time to refer. An overview of the three main types of surgery and their outcomes are discussed. Less experienced practitioners will feel better able to talk to patients about OSA and for those with a special interest in OSA there is new material to stimulate further discussion.

  • Volume 21 Diagnosis and management of potentially malignant oral disorders
    • Abstract: De Silva, HL The optimum management strategy for potentially malignant disorders remains a constant challenge as our present knowledge is still short of being conclusive. In spite of its shortcomings as an accurate predictive marker, the assessment of the severity of epithelial dysplasia continues to be useful in risk assessment. It is important to use a combination of epidemiological, clinical and histopathological input when deciding on the most appropriate management for an individual patient. Advanced research exploring molecular markers for diagnosis and risk predictions appear to be promising. However, these tests have not evolved to a stage that they could be used for routine diagnostics at the clinical setting.

    • Abstract: Nolan, Anita As the oral cavity marks the beginning of the gastrointestinal tract (GIT), it is not surprising that it frequently mirrors disease that occurs lower in the GIT. Increasingly, clinical signs in the oral cavity are recognized as future predictors and prognostic indicators of GIT and, indeed, other systemic disease. This paper discusses recent advances in the overlap area of Oral Medicine and Gastroenterology and the significant role of the dental practitioner in the management of these patients.

  • Volume 21 Caries management: Is the "seal the deal"'
    • Abstract: Foster, Lyndie A A barrier to providing sealants has been the concern about inadvertently sealing over caries, but today the management of dental caries has evolved from the domain of techniques based on complete removal of carious tissue prior to tooth restoration or sealant, to include a range of techniques where some, or even all caries is sealed in beneath restorations, sealants or infiltrants. There is a significant, and growing, evidence base supporting these techniques as caries management strategies for children and adolescents. These techniques are not new but build on earlier concepts and research. These concepts offer a real way forward and departure from invasive restorative treatments. Some issues, however, are not completely resolved, and future solutions may herald a new era of restorative dentistry, perhaps with the concept of filling with no drilling since the "seal is the deal". These techniques and issues will be considered in the New Zealand context.

  • Volume 21 The mutilated dentition - orthodontic considerations
    • Abstract: Harding, Winifred A mutilated dentition is one in which teeth have been extracted, traumatically lost, extensively restored or extensively worn. Patients have become more dentally aware over the years and have been led by both television and the Internet to expect instant makeovers and perfect smiles. In the USA there was an 800% increase in adults receiving orthodontic treatment between 1970 and 2003. Despite this, it still comes as a surprise to many adult patients that braces are effective and widely used as part of the rehabilitation process.

  • Volume 21 The mutilated dentition - management of the debilitated
           dentition
    • Abstract: Hanlin, Suzanne M An interdisciplinary treatment plan is often required to allow restoration of function and aesthetics in the "mutilated dentition". Loss of teeth is associated with social and psycological impacts for the patient, however most often aesthetic requirements and financial constraints predominate in the treatment decision making. Historically, unfavourable occlusal contacts have been viewed as predisposing factors in the development of temporo-mandibular joint dysfunction (TMD). This linkage has now been refuted by many authors and it is understood that occlusion may be a co-factor only in TMD. In determining the "ideal occlusion" to restore the mutilated dentition consideration must be given to an occlusion that is physiologic for the patient, and the simplest scheme to construct from a clinical and technical view point. In successfully restoring function of the teeth an aesthetic outcome can be achieved. The planning and treatment for three patients is reviewed to highlight interdisciplinary patient care from a prosthodontics perspective.

  • Volume 21 "MI" caries management - an overview
    • Abstract: Banerjee, Avijit Minimum intervention dentistry, with its non-operative prevention and control of disease, underpins the basis of a patient-centred, team-based approach to managing dental caries in patients, who must take an active responsibility in maintaining their personal oral health. In patients where cavities are present causing pain, poor aesthetics and/or functional problems, restorations will need to be placed. Minimally invasive caries excavation strategies can be deployed depending on the patient's caries risk, lesion-pulp proximity and vitality, the extent of remaining supra-gingival tooth structure and clinical factors (e.g., moisture control, access) present in each case treated. Excavation instruments, including burs/handpieces, hand excavators, chemo-mechanical agents and/or air-abrasives which limit caries removal selectively to the more superfi cial caries-infected dentine and partial removal of caries-affected dentine when required, help create smaller cavities with healthy enamel/dentine margins. Using adhesive restorative materials, the operator can, if handling with care, optimize the histological substrate coupled with the applied chemistry of the material so helping to form a durable peripheral seal and bond to aid retention of the restoration as well as arresting the carious process within the remaining tooth structure. Achieving a smooth tooth-restoration interface clinically to aid the co-operative, motivated patient in biofilm removal, is an essential pre-requisite to prevent further secondary caries.

  • Volume 21 Periodontal diseases: Basic concepts, association with systemic
           health, and contemporary studies of pathobiology
    • Abstract: Papapanou, Panos N 'Periodontal diseases' is a collective term used to describe the infl ammatory changes of the tooth supporting structures, i.e., the gingiva, the alveolar bone, the periodontal ligament and the root cementum, that may lead to tissue destruction, reduced tooth support and, ultimately, to tooth loss. Commonly in medicine, classification systems for pathologic conditions are ever evolving schemes that are periodically revised to refl ect current knowledge related to the clinical presentation, aetiology, pathobiology, treatment response or long term prognosis of the disease in question. The classification of periodontal diseases is no exception; after several revisions over the years, the currently accepted system refl ects the consensus report of a 1999 International Conference. The classification recognizes eight main categories, three of which (Gingival Diseases, Chronic Periodontitis and Aggressive Periodontitis) will be involved in the present series of lectures.

  • Volume 20 Coronectomy as the treatment of choice in wisdom teeth showing
           radiographic signs of close proximity to inferior dental nerve
    • Abstract: Leung, Yiu Yan; Cheung, Lim Kwong The aim of the study is to compare the prevalence of post-operative inferior dental nerve (IDN) deficit after coronectomy with total removal of wisdom teeth showing specific radiographic signs of close proximity to IDN. A randomized clinical trial comparing total removal and coronectomy of wisdom tooth was conducted. Analyses of the correlations of IDN deficit and various radiographic signs of wisdom tooth roots showing close proximity to IDN were performed. Two radiographic signs were found to be positive predictors of intra-operative IDN exposure. Specific radiographic signs or the presence of two or more radiographic signs are positive predictors of post-operative IDN deficit. The study concluded that darkening of the wisdom tooth root and presence of two or more specific signs in radiographs significantly increased the risk of IDN deficit in lower wisdom tooth surgery. Coronectomy can significantly reduce the prevalence of an IDN deficit in patients with lower wisdom teeth showing radiographic signs of close proximity to IDN. It also carries less surgical morbidities when compared with total removal of lower wisdom tooth.

    • Abstract: Leung, Yiu Yan; Cheung, Lim Kwong The aim of the study was to compare the surgical complications and neurosensory disturbance of coronectomy and conventional excision of lower third molars with roots in close proximity to inferior dental nerve. We conducted a randomised clinical trial of patients with lower third molars showing specific radiographic signs was conducted. Patients were randomised to undergo either coronectomy or total excision (control) of the lower third molar. It was concluded that coronectomy can significantly reduce the incidence of inferior dental nerve deficit when compared with conventional excision when the roots show radiographic signs of close proximity, and the technique showed a similar rate of other surgical morbidities.

    • Abstract: Zhang, WT; Daly, CG; Mitchell, D; Curtis, B Changes to antibiotic prophylaxis guidelines for the prevention of infective endocarditis (IE) have occurred in part due to similar incidences of bacteraemia caused by oral hygiene procedures as compared with dental treatments for which antibiotic prophylaxis has traditionally been provided. Viridans streptococci are important pathogens in IE. However, there is little evidence available comparing the magnitude of bacteraemia caused by oral hygiene activities with that caused by periodontal treatment. The aims of this study were to investigate the incidence and magnitude of viridans streptococcal bacteraemia (VSB) due to flossing as compared with scaling and root planing (SRP) in the same individual.

  • Volume 20 Osseointegration - the influence of implant surface
    • Abstract: Ivanovski, Saso The modification of implant surfaces from the original machined to 'micro-rough', and more recently 'bioactive', surfaces has been proposed to improve clinical outcomes. This review outlines the evidence for the superior performance of modified implant surfaces. Pre-clinical trials consistently show that modified implant surfaces are more osteogenic and improve the degree of osseointegration. Clinically, there is a clear trend for improved clinical success with 'micro-rough' compared with machined implants. This is particularly the case in compromised sites, such as the posterior maxilla, and compromised patients, such as smokers. Furthermore, 'micro-rough' implant surfaces perform better in augmented sites, and facilitate the more predictable use of short implants, thus reducing the need for more invasive augmentation procedures. 'Micro-rough' implants have been associated with an increased susceptibility to peri-implantitis, but these findings relate to a surface that is no longer manufactured. Newly developed 'bioactive' surfaces have only been evaluated in a limited number of clinical studies.

  • Volume 20 The missing link in minimal intervention dentistry: Effective
           caries control
    • Abstract: Ngo, Hien In the later part of the 19th century, there was no clear distinction between carious process and the lesion, so the term caries was used to refer to the cavity which can be found on tooth surfaces. It was in this setting that Dr Miller (1890) introduced the chemo-parasitic theory of caries, which stated that caries only develops in the presence of acids which are produced by bacteria living mainly in saliva. It was one of his contemporary colleagues, Dr Black, who observed the association between the accumulation of plaque and the development of cavities, this is the first association between dental biofilm and caries. This observation led to the universal acceptance of the extension for prevention principle, which required the extension of the boundaries of a cavity preparation out to self cleansing areas. Until recently, there was no real appreciation of the evolutionary nature of dental biofilm, its sophisticated structure and physiology and its important role in maintaining oral and general health.

  • Volume 20 Repair of critical size defects in the rabbit calvarium with the
           use of a novel scaffold material
    • Abstract: Portnof, Jason; Heggie, Andrew A; Shand, Jocelyn M A number of materials have been implanted into skull defects to determine if improved healing outcomes can be achieved. In some instances, packing or implanting bone-inducing alloplasts into a standardized skull defect results in better healing than an untreated defect. AlloDerm is a skin derived acellular collagen membrane and has characteristics that are known to be effective in promoting bone growth. It has not been previously investigated for use in cranial bone healing. The aim of the investigation was to determine if implanting this novel scaffold into skull defects will improve the quality of bone repair. Six rabbits received AlloDerm grafts into critical-sized calvarial defects. The rabbits were sacrificed at two months and the specimens examined histologically and radiographically. At the time of sacrifice, it was found that while bony growth had commenced at the margins of the defect and as isolated islands within the graft, there did not appear to be a major benefit in using the material described.

  • Volume 20 Novel approaches in 3-dimensional facial profiling to establish

    • Abstract: Claes, Peter; Walters, Mark; Clement, John When confronted with facial dysmorphologies, three-dimensional (3D) facial harmony is preferably assessed with regard to normality. This, however, presents two major challenges. The first challenge is to define normality. What makes non-dysmorphic faces appear normal' The second challenge is to situate the craniofacial dysmorphology with respect to normality. What makes the dysmorphic face not appear to be normal' To tackle these challenges, a novel approach based on a Face Space is proposed. In essence, faces are represented as points in a High-dimensional space, the dimensions of which capture important sources of allowed facial variation within a normal population. To establish an aesthetic objective of a given dysmorphic face, the novel concept of the "normal equivalent" of that face via robust projection into the Face Space is proposed. This technique is demonstrated on an artificial example in which smiling whilst showing teeth is considered a surrogate for facial dysmorphology.

  • Volume 20 Ridge preservation: Does it actually work'
    • Abstract: Darby, Ivan Post-extraction the alveolus undergoes modelling which reduces height and width. This may present a problem for subsequent crown and bridge or implant therapy. Ridge preservation is the use of grafts and/or membranes to try to minimize the loss of the alveolar ridge. Extraction sockets have been filled with autogenous, allogenic and alloplastic materials. Membranes or soft tissue were used to contain the graft. More recently biodegradable sponges and materials coated in growth factors have been tested. Studies have primarily looked at either maintenance of vertical and horizontal dimensions or the healing of the socket and how much of the graft material is incorporated into the newly formed bone. Irrespective of method or materials, there seems to be some maintenance of the alveolus. Bone fill seems to occur in preserved extraction sockets, but in most cases with a high percentage of residual graft particles. In general, there is a lack of evidence to show that ridge preservation aids in correct 3-D implant placement, maintains hard and soft tissue volume over a prolonged period of time or for success and survival of implants placed into ridge preserved sockets. Still the most effective way to maintain ridge volume is to keep the natural tooth.

At the same time concerns are being raised that students with relatively little training, practise to improve their skill on patients with all of the inherent risks that may occur. Simulation in dentistry has been practised for many years and so the concept is not new to the profession. New tools have been developed that both enhance teaching and learning and are also useful for assessment of students and trainees. The challenge of virtual and simulated reality tools is to have the required fidelity to improve teaching and learning outcomes over the currently utilized methodology.

Given that few very young children actually attend dental health services, there is a role for non-dental healthcare professionals in the prevention of dental disease and the promotion of oral health. This presentation will take an evidence-based approach to explore opportunities for increased collaboration between dental and non-dental healthcare professionals to optimize the health outcomes for children. The role and responsibilities of the dental profession in developing this model of shared care will also be discussed.

  • Volume 19 Uses of Sodium Fluoride Varnish in Dental Practice
    • Abstract: Chu, CH; Lo, Edward Fluoride varnish is developed to prolong the contact time between fluoride and tooth surface, so that the tooth becomes more resistant to caries attack. The active ingredient of fluoride varnish is usually 5% sodium fluoride, (22,600 ppm fluoride). Studies have found that fairly insoluble globules of calcium fluoride-like material formed on the tooth surface after topical fluoride application. These globules act as a reservoir of fluoride in the mouth for a prolonged period of time. Systematic reviews corroborate evidence for the efficacy of fluoride varnish in the prevention of dental caries. Sodium fluoride varnish is used to prevent caries development, arrest early enamel and even soft dentine caries through promotion of demineralisation of carious tooth substance. It is also used to treat tooth hypersensitivity. Some use it as a provisional luting agent by itself or combined with other provisional luting agents for cementing provisional crowns. Fluoride varnish has recently gained much attention in dentistry because it is quick and easy to apply. It sets rapidly on teeth, and gagging and swallowing is unusual. Side-effects or complications of its use are rare. Studies show that fluoride varnish is safe for young children and the risk of dental fluorosis is minimal. The simplicity of its application makes it very suitable and practical for use in dental clinics and outreach dental services, especially in young children and in other special needs groups.

    • Abstract: Ow, Andrew Tjin-Chiew; Cheung, Lim Kwong Bilateral sagittal split osteotomies (BSSO) and mandibular distraction ostoegenesis (MDO) have both been applied in the surgical treatment of Class II mandibular hypoplasia. This randomized controlled trial aimed to compare the stability and morbidities of both techniques. From the preliminary data, skeletal relapse seems to be comparable between BSSO and MDO within the first post-operative six months. Objective and subjective neurosensory evaluation showed no significant difference in all mean scores for LT, 2PD and PPPT between both surgical techniques. Localized wound infection was a common post-operative complication for MDO. A greater sample size is required to ascertain which technique is better.

  • Volume 19 Influence of Nicotine on Blood Perfusion and Bone Healing during
           Distraction Osteogenesis
    • Abstract: Ma, L; Zheng, LW; Cheung, LK Nicotine is the main chemical component in tobacco products and its effect on bone healing remains controversial. This study aims to evaluate the influence of nicotine on blood perfusion and bone healing using a rabbit model of mandibular distraction osteogenesis. The dose dependent effect of nicotine on bone regeneration, and the effect of nicotine on blood perfusion and angiogenesis were assessed by radiography, micro-computed tomography, histological and immunohistochemical analysis, real time PCR and Laser Doppler monitoring. Results showed that bone healing was compromised by high dose nicotine treatment. Nicotine exposure increased microvessel density, whereas inhibited blood flow and bone formation. The expression of bone morphogenetic protein (BMP)- 2 in osteoblasts was also decreased. The present study supported that nicotine has a dose dependant influence on bone healing in distraction osteogenesis. Nicotine compromises bone regeneration possibly by causing ischemia and inhibiting BMP expression in osteoblasts. Nicotine exposure enhances angiogenesis but can not compensate for the adverse effect of vasoconstriction.

  • Volume 19 Antibiotics in the Treatment of Periodontal Diseases:
           Microbiological Basis and Clinical Applications
    • Abstract: Feres, Magda The starting point for defining a therapy, whether in dentistry or the various areas of medicine, is to understand the aetiology and progression of the different illnesses. In this context, it is worth pointing out that periodontal diseases are a group of infections whose primary aetiological factor is the bacteria present in the oral cavity, especially those that colonize the supra- and subgingival tooth surfaces. Many advances, mainly those occurring over the last two decades, greatly facilitated understanding of the aetiopathogenesis of periodontitis, including the microbiota related to each type of disease and the host response. This knowledge has made it easier to indicate more specific therapy, including the use of systemic antibiotics. Systemically administered metronidazole, and especially the combination of metronidazole, amoxicillin and scaling and root planing (SRP) leads to a beneficial change in the composition of the subgingival microbiota by reducing pathogens and allowing the growth of host-compatible species. In addition, the combination of systemic antibiotics and a strict control of supragingival plaque during the active phase of therapy has been showing promising results in the treatment of chronic periodontitis.

  • Volume 19 Diagnosis and Management of the Worn Dentition: Conservative
           Restorative Options
    • Abstract: Meyers, Ian A A technique is presented for the use of a transparent polyvinyl siloxane template constructed from a diagnostic wax-up to rapidly reproduce the anatomical structure with direct restorative materials in the mouth. This technique is beneficial for a number of geriatric patients who would be unable to undertake long and complex dental treatment sessions and provides an alternative for those unable to meet the immediate costs of multiple indirect restorations. Consideration of increases in vertical dimension to create space for the new restorations and reconstruction utilising a combination of direct and indirect procedures provides control and predictability over the final restorative result. In the short to medium term, the use of minimally invasive adhesive techniques enables tooth surface loss to be replaced with minimal destruction of the remaining sound tooth material, yet still enables the option for a more definitive restorative option at a later date.

  • Volume 19 Diagnosis and Management of the Worn Dentition: Risk Management
           and Pre-restorative Strategies for the Oral and Dental Environment
    • Abstract: Meyers, Ian A The incidence of tooth wear or non-carious tooth surface loss (NCTSL) is increasing and oral rehabilitation of patients with tooth tissue loss requires strategies that address all the factors relevant to the aetiology and pathogenesis of the disease. The multifactorial nature of the disease and the variability in its clinical presentation provides treatment challenges for the clinician. Management of tooth wear must be more than just restoration. Risk assessment, compliance and a commitment from both professional and patient underpin overall success of the treatment. Understanding that long term success is affected by the patient's oral environment and how diet, lifestyle and medical factors modify this environment. Improvements in the quantity and quality of saliva and remineralization strategies to enhance the remaining tooth structure are essential pre-restorative requirements. Successful management requires recognition of the problem, stabilization of the oral environment, remineralization of the tooth structure and when appropriate restoration.
