  • The “New” Genetics and Its Impact on Oral Care Delivery
    • Authors: Robert J. Weyant
      Pages: 140 - 146
      Abstract: Abstract We are entering an age where health care providers, patients, and inevitably insurers will have access to unprecedented amounts of patient-level information from genetic sources that have a direct bearing on a patient’s risk, prognosis, and response to potential treatment for a number of diseases. This era of new genetics offers an implicit promise that with such detailed data will come improvements in patient outcomes. As the realization of the complexity of genomic data grows, the time at which the new genetics actually provides us with affordable and actionable information that improves patient outcomes is continually being pushed back. The degree to which clinical dental practice will be transformed by genomic science will depend ultimately on yet unanswered questions involving not just how fast these technology changes occur but also on the degree that we understand and manage associated issues, including patient ethics, dental care financing, dentist training, and effective use of the electronic health record.

  • Current Developments in 3D Printing for Craniofacial Regeneration
    • Authors: Cedryck Vaquette; Peter Mark Bartold; Saso Ivanovski
      Abstract: Abstract Three dimensional printing, or additive manufacturing, allows the production of customized scaffolds that can enhance craniofacial reconstruction and regeneration. It can be achieved by several techniques, including selective laser sintering, electron beam melting, fused deposition melting, fused filament fabrication, as well as extrusion and laser-assisted bioprinting of cells. 3D-printed constructs can take the form of nonresorbable solid form prosthesis or porous degradable scaffolds that can be resorbed over time and replaced by native tissues. The later can be considered the more desirable outcome but it is also more challenging to achieve. 3D-printed constructs have been used in a variety of oro-dental and craniofacial applications, including vertical bone augmentation, mandibular, and skull defect reconstruction, periodontal regeneration, and temporomandibular joint replacement. Although considerable advancements have been made, challenges remain in translating this technology to the clinic, especially in producing customized, porous, and inter-connected scaffolds for the regeneration of complex multiphasic tissues of varying dimensions ranging from a few millimeters to several centimeters.

  • How Far Have We Come in the Field of Nerve Regeneration After Trigeminal
           Nerve Injury'
    • Authors: Annika Rosén; Arezo Tardast; Tie-Jun Shi
      Abstract: Abstract Patients suffering from nerve injury with sensory disturbances or orofacial pain have greatly reduced quality of life, and it is a big cost for the society. Abnormal sensations caused by trigeminal nerve injury often become chronic, severely debilitating, and extremely difficult to treat. In general, non-invasive treatment such as drug treatment has been insufficient, and there are currently few available effective treatments. Surgical interventions such as end-to-end connection or nerve grafting have disadvantages such as donor site morbidity or formation of neuroma. There is need for optimizing the technique for nerve repair, especially for the trigeminal nerve system, which has so far not yet been well explored. Recently, tissue engineering using biodegradable synthetic material and cell-based therapies represents a promising approach to nerve repair and it has been reported that mesenchymal stem cell (MSC) has an anti-inflammatory effect and seems to play an important role in nerve healing and regeneration.

  • Oral Cavity and Allergy: Meeting the Diagnostic and Therapeutic Challenge
    • Authors: Eleni Papakonstantinou; Ulrike Raap
      Abstract: Abstract Allergic reactions of the oral mucosa are associated with diverse symptoms and can severely affect patients’ quality of life. Oral mucosa changes such as stomatitis or lichenoid reactions can be the first evidence of a contact allergy, with oral lichenoid reactions after contact with dental restorations, especially amalgam fillings, being among the most common clinical reactions. Additives in foods and oral hygiene products may also cause allergic mucosal reactions. Subjective symptoms, such as pain, burning feeling, or dryness of the oral mucosa, as well as cheilitis or lip and facial swelling, may not only have an allergic component but may also be associated with other diseases that have to be excluded. A complete and thorough clinical examination of the oral mucosa is the first step in the diagnosis of a contact allergy. A detailed history of the patient’s oral care products, drugs, and dental materials is both essential and helpful for the clinician. As a result of the presence of mucosal changes, a patch test can be used for the diagnosis of contact allergy of delayed type. Although the patch test is the standard diagnostic tool for such types of contact allergy, proper interpretation of patch-test results and their clinical relevance can be challenging. As the number of patients with allergies resulting from different materials increases over the years, and a larger number of different dental materials are found to induce an allergy, it is essential for dentists to be aware of the possible allergic reactions to dental materials. Thus, we aimed to develop a systematic approach for contact allergy of the oral cavity, focusing not only on clinical manifestations and diagnosis but also on management and prediction of the risk of oral allergic reactions. A multidisciplinary approach for patients with an oral allergy is essential, with participation of physicians of different specialties, including dentists, allergists and dermatologists.

  • Feasibility of Periodontal Tissue Regeneration Therapy with
           Adipose-Derived Stem Cells
    • Authors: Morikuni Tobita
      Abstract: Abstract Adipose-derived stem cells within subcutaneous adipose tissue were first reported in 2001. Since then, the number of regenerative medicine studies investigating adipose-derived stem cells (ASCs) has increased dramatically. This has included not only basic research in regenerative medicine using ASCs but also has progressed and clinical safety studies have now commenced in Japan. Translational research (including clinical research and clinical trials) using cell therapy aims to verify the possibility of achieving repair of tissue or its function and investigating the safety of these protocols. However, despite this simplicity, elucidating the mechanism of action of implanted processed cells is difficult. This indicates the necessity for the further discussion focusing on translational research for cell therapy, as well as continuing to develop novel therapeutic strategies. In this paper, we discuss the feasibility of practical application of using ASCs for periodontal tissue regeneration therapy and discuss the legal system for promoting the practical application of regenerative medicine recently enforced in Japan.

  • Progress in Bioengineered Whole Tooth Research: from Bench to Dental
           Patient Chair
    • Authors: Elizabeth E. Smith; Pamela C. Yelick
      Abstract: Significance Tooth loss is a significant health issue that affects the physiological and social aspects of everyday life. Missing teeth impair simple tasks of chewing and speaking and can also contribute to reduced self-confidence. An emerging and exciting area of regenerative medicine-based dental research focuses on the formation of bioengineered whole tooth replacement therapies that can provide both the function and sensory responsiveness of natural teeth. This area of research aims to enhance the quality of dental and oral health for those suffering from tooth loss. Current approaches use a combination of dental progenitor cells, scaffolds and growth factors to create biologically based replacement teeth to serve as improved alternatives to currently used artificial dental prosthetics. Purpose This article is an overview of current progress, challenges, and future clinical applications of bioengineered whole teeth. Conclusion Recent accomplishments suggest that whole tooth bioengineering for human tooth replacement is indeed possible and, in fact, is the future of dentistry.

  • Epidemiology of Sjögren’s Syndrome—from an Oral
           Perspective
    • Authors: Anne Isine Bolstad; Kathrine Skarstein
      Abstract: Abstract Oral symptoms are among the most distressing manifestations for patients with Sjögren’s syndrome (SS). The feeling of dry mouth is unpleasant, and hyposalivation may contribute to difficulty in speaking, chewing and swallowing and reduced quality of life. Reduced salivary flow increases the risk for dental caries and problems with prosthetic replacement. It seems that SS is not as frequently occurring as previously anticipated. Population-based prevalence studies on primary SS in Europe, conducted on large background populations and in accordance with the AECG criteria, reported of a prevalence of 1–9 cases per 10,000 people. This gives a combined prevalence of nearly 39/100,000 (~0.04 %). The cause of Sjögren’s syndrome is even now not fully understood, and the treatment of oral symptoms is still mostly palliative. Hopefully, useful information will appear from the new methods that are now available for genome wide association studies, epigenetics, DNA methylation studies, and proteomics. Similarly, this is anticipated for the immunological side of the story. The interferon signature, the interferon γ/interferon α mRNA ratio, and CXCL13 are among the proposed biomarkers of active disease. In this review, we provide an update on oral aspects of Sjögren’s syndrome with emphasis on the latest publications on these topics.

  • The Role of Silane Coupling Agents and Universal Primers in Durable
           Adhesion to Dental Restorative Materials - a Review
    • Authors: Muhammad Zakir; Usman Ashraf; Tian Tian; Aifang Han; Wei Qiao; Xiaozhuang Jin; Meng Zhang; James Kit-Hon Tsoi; Jukka Pekka Matinlinna
      Abstract: Abstract One of the most important aspects in the field of dentistry is adhesion. Adhesion can be enhanced through different mechanisms, most commonly by chemical and mechanical modifications of dental material surfaces. One example of chemical adhesion utilizes primers or bonding agents containing coupling agents. Universal primers which are (mainly organophosphate-based monomers) and silane coupling agents are the most effective and most widely used for unifying dissimilar materials. Other than improving adhesion, Silanes have many other applications in dentistry. They have been found also to enhance the mechanical properties of materials either by adhesion or by becoming a constituent of dental materials itself. Universal primers, on the other hand, are utilized in bonding between different dental materials such as ceramics, metals, alloys, as well as to resin composites. Unfortunately, these primers, coupling agents, and bonding agents have, in general, poor hydrolytic stability. They are susceptible to humid oral environment, which invariably render them potentially unstable in the humid oral environment as saliva is always present. Improving their hydrolytic stability should therefore result in stronger adhesion for dental materials and dental prosthesis with a better clinical survival rate.

  • Modifiable Risk Factors for Periodontitis and Diabetes
    • Authors: Wenche S. Borgnakke
      Abstract: Abstract This review describes the evidence published from January 2013 through March 2016 for modifiable risk factors for chronic periodontitis and diabetes mellitus. Risk factors are factors that increase the chance of developing the disease. Modifiable risk factors for both these chronic, inflammation-related diseases include the following: hyperglycemia; microbial overgrowth, infection, and inflammation (virus, poor oral hygiene, gut microbiome); overweight and obesity; metabolic syndrome; hyperlipidemia; medication; unhealthy diet (added sugar; alcohol and other non-sugary carbohydrates, fat, and meat; nutrition, minerals (including zinc), and vitamins); current tobacco smoking (including environmental tobacco smoke); sedentary lifestyle; sleep disturbances; stress, depression, anxiety, poor coping skills, and allostatic load; low health literacy; and the environment and pollution.Given the similarity between the inflammatory mechanisms underlying chronic periodontitis and diabetes mellitus, one can wonder: Could these diseases both be somewhat different manifestations of inflammatory response-based overload? Could both periodontitis and diabetes even be regarded as autoimmune diseases that are manifested due to poor biologic and psychologic coping skills in response to the micro- and macro-level stressors that cause inflammation?Any successful intervention must include more measures than clinical medical/dental care can provide and hence might benefit from active participation of all parties, first and foremost the patient, in a patient-centered, interprofessional health care (not merely disease care) collaboration for the benefit of the mutual patient.But first, it is necessary to be aware of the risk factors that can be modified to pose less risk, a goal toward which this review hopefully will be helpful.

  • Bonding of Dental Ceramics to Titanium: Processing and Conditioning
           Aspects
    • Authors: Maja Antanasova; Peter Jevnikar
      Abstract: Abstract Difficulties related to titanium processing (casting) and the problematic titanium-ceramic bond have been limiting the latter’s application in prosthetic dentistry for many years. Recent advances in subtractive and additive CAD/CAM technologies have provided alternative routes for titanium processing. The effect of a processing route on titanium surface characteristics and on the strength of its bond to porcelain need to be assessed, since most paths for enhancing porcelain bonding involve preparation of the titanium surface. Several approaches to bond enhancement have been proposed, some of which are widely accepted (abrasion by airborne-particle and application of a bonding agent), while others have not resulted in a clinical breakthrough. Despite efforts to improve titanium bonding to porcelain and to develop titanium compatible, low-fusing porcelains, many in vitro studies report bond strengths to titanium that are inferior to those for base metals and noble dental alloys. Only a few clinical studies have been reported, revealing that titanium-ceramic restorations are susceptible to mechanical complications (porcelain fractures in 33 % of cases). Current knowledge on titanium-ceramic bonding is here reviewed, focusing on the recent attempts to overcome the limitations of the system and on recent advances in titanium processing. Optimization of the currently available processing and surface conditioning methods seems to be necessary. Although most of the proposed surface preparation methods (surface coating and roughening) appear to show a certain degree of porcelain bond improvement, many of them require application of additional complex procedures. Simplification and improved efficiency therefore appear to be the essentials for implementation of these methods in clinical practice.

  • Geriatric Oral Health Care Delivery in the United States of America
    • Authors: Ahmed A. Al-Sulaiman; Judith A. Jones
      Abstract: Abstract The growing elderly population (≥65 years) imposes great challenges to oral health delivery systems. In the USA, the elderly continue to exhibit a high prevalence of chronic oral disorders. Further, poor dental access has long remained a concern and a barrier toward oral health improvement. Lack of dental insurance is a prominent contributor to the access problem. The main reason for the lack of dental insurance is the loss of employer benefits after retirement and the current transition to a national insurance program (Medicare) with insignificant dental benefits. Dental care needs to be established earlier in life through an appropriate model of care that considers the level of dependency of the elderly. The goals of dental treatment for the elderly are different from those for any other age group, and there is an increased need for the provision of dental care in regions with large elderly populations. This paper provides an overview of the challenges imposed on the health care delivery system in the USA with regard to the provision of oral health care to older adults and discusses consideration for future improvement.

  • SBIRT-Based Interventions to Improve Pediatric Oral Health Behaviors and
           Outcomes: Considerations for Future Behavioral SBIRT Interventions in
           Dentistry
    • Authors: Josué Cuevas; Donald L. Chi
      Abstract: Abstract Dental caries is the most common chronic disease in children and is caused by poor oral health behaviors. These behaviors include high-sugar diet, inadequate exposure to topical fluorides, and irregular use of professional dental care services. A number of behavioral intervention approaches have been used to modify health behaviors. One example is based on the Screening, Brief Intervention, and Referral to Treatment (SBIRT) model, which has been widely used to reduce substance abuse in both adults and children. SBIRT is a promising behavior change approach that could similarly be used to address problematic oral health behaviors. In this paper, we will review oral health studies that have adopted SBIRT components, assess if these interventions improved oral health behaviors and outcomes, and outline considerations for researchers interested in developing and testing future oral health-related interventions in dentistry using a SBIRT approach.

  • Ceramic-Reinforced Polymers: CAD/CAM Hybrid Restorative Materials
    • Authors: Sillas Duarte; Neimar Sartori; Jin-Ho Phark
      Abstract: Abstract Newly developed ceramic-reinforced polymers CAD/CAM restorative materials (CRP) represent a viable esthetic material for dental restorations. They can be classified into polymer-infiltrated ceramic (PIC) and resin nano-ceramic (RNC). This review article analyzes the latest scientific findings on wear, fatigue resistance, bonding mechanisms, fracture resistance, and esthetic properties. The literature shows that fatigue resistance of ceramic-reinforced polymers appears to be adequate to survive the masticatory forces. PIC and RNC CAD/CAM blocks have similar fracture toughness, but lower than that of ceramic-based CAD/CAM blocks. The roughness of polished different ceramic-reinforced polymers is comparable; however, aging increases the surface roughness significantly. Different CRPs require a dedicated surface treatment; nonetheless, PIC and RNC are able to attain high bond strengths. The esthetic properties of CRPs are clinically acceptable. Ceramic-reinforced polymers appear to be an ideal material for minimally invasive restorations.

  • A Critical Evaluation of Fatigue Studies for Restorative Materials in
           Dentistry
    • Authors: Martin Rosentritt; Michael Behr; Verena Preis
      Abstract: Abstract Fatigue tests are state of the art in dental materials testing for estimating the lifetime performance of materials or restorations. A number of different loading situations are tested with varying parameters, which are based on statistical methods or clinical experience. Partly, inadequate information is provided for a sufficient description and evaluation of the applied methods and resulting data. Several in vitro studies with limited clinical relevance have been published. This review gives a critical overview of fatigue methods published in dental literature. A clear differentiation should be made between fatigue tests for fundamental materials research and component testing of dental restorations. For structural testing, a correlation between in vitro data and in vitro performance is required. Correlation should be based on detailed evaluation of the clinical situation.

  • Biodegradation of Resin-Dentin Bonds: a Clinical Problem'
    • Authors: Ricardo M. Carvalho; Adriana P. Manso
      Abstract: Abstract Biodegradation of the resin-dentin interfaces has been a focus of research over the last decade. Most studies show that degradation of both the collagen and the adhesive take place within short periods of time after bonding, and claim that such loss of structure at the interface opens opportunity for secondary caries initiation and progression thus leading to failure of the restoration. Open margins are further compromised by thermo-mechanical loading and enzymes produced by local bacteria. While marginal gaps appear to be unavoidable, it is remarkable that resin composite restorations can deliver successful clinical service for many years provided preventive and conservative measures to reduce the caries-risk of the patient are applied along with the restorative treatment. This review will look into the evidence from laboratory studies that investigated degradation of bonds and the consequences leading to clinical failure and balance that against the results of clinical trials that evidence the factors associated with the durability and clinical success of resin composite restorations.

    • Authors: Nadim Z. Baba
      Abstract: Purpose of Review The motive of this article is to single out the materials and processes available for the fabrication of CAD/CAM complete dentures. Recent Findings CAD/CAM complete denture fabrication has become accessible for complete dentures with a variety of techniques available for the fabrication of the prostheses. The majority of the manufacturers use subtractive manufacturing for the fabrication of their dentures while only one manufacturer proposes an additive technique. Several digital systems are available for the fabrication of CAD/CAM dentures. Summary The integration of CAD/CAM technology into complete denture design and fabrication helps improve the quality of the dentures and simplify the laboratory work. Time-consuming laboratory procedures are reduced or eliminated allowing the dental technician to ensure reproducible, efficient, and accurate prostheses.

  • Improving the Oral Health of American Indians and Alaska Natives
    • Authors: Kathy R. Phipps
      Abstract: Abstract American Indian and Alaska Native people experience more oral disease and are more likely to have unmet oral health needs than the general US population. These disparities may be attributed to limited access to and use of the dental care delivery system plus a high prevalence of disease risk factors such as social inequities, diet and infant-feeding practices, smoking, and oral hygiene behaviors. This review provides information on the use of and effectiveness of strategies designed to increase access, prevent oral disease, and change systems. To address the oral health crisis in Indian Country, a multi-modal approach which engages the individual, family, community, tribal leadership, plus health and social service providers must be developed, implemented, and sustained. This multi-modal approach should combine primary, secondary, and tertiary prevention strategies layered with strategies to increase access and system changes to reduce the consequences of social inequities.

  • Current Status of Adding Dental Therapists to the Oral Health Workforce in
           the United States
    • Authors: Kavita R. Mathu-Muju; Jay W. Friedman; David A. Nash
      Abstract: Abstract Dental therapists are members of the oral health care workforce in over 50 countries of the world. Until recently, they have not participated as members of the professional dental team in the USA. It was not until the publication of Oral Health in America: A Report of the Surgeon General in 2000, describing the significant problem of access to dental care, that the issue of dental therapists emerged in the USA in a significant manner. Details of the development of dental therapists in the workforce in the USA through 2011 were previously chronicled by Mathu-Muju. Since then, there has been a major increase in interest and licensing of dental therapists in a number of states. This article updates the dental therapist movement to the present time. The literature and activities of the movement will be reviewed by the categories of research, education, and legislation/practice, as well as analytical essays and commentaries.

  • Artificial Aging of Zirconium Dioxide: An Evaluation of Current Knowledge
           and Clinical Relevance
    • Authors: Mutlu Özcan; Cláudia Ângela Maziero Volpato; Márcio Celso Fredel
      Abstract: Abstract Due to its superior mechanical properties, yttrium-stabilized tetragonal zirconia polycrystal is considered as one of the most promising materials to manufacture prosthetic frameworks, monolithic crowns, and abutments for implants in dentistry. When stabilized in the tetragonal phase, the structure of zirconia can respond to external stress by increasing its toughness and resistance. Unfortunately, when subjected to a humid environment, zirconia may undergo considerable degradation characterized by increased surface roughness, grain growth, and propagation of microcracks that could be detrimental for its mechanical properties. This phenomenon, also known as low-temperature degradation (LTD), when not minimized, may represent a setback for the longevity of zirconia especially used for biomedical applications. LTD is studied in in vitro or in vivo settings employing different strategies. Present clinical studies, however, with their shortcomings, do not signify high incidence of failures of zirconia for dental applications. The LTD of zirconia is currently being criticized based on laboratory testing which may be suboptimal. This review will highlight the existing knowledge on the artificial aging methods studying LTD in zirconia and their relevance considering clinical performance of zirconia prostheses.
