  • Treatment Of External Apical Root Resorption With Mineral Trioxide
           Aggregate: Two Case Reports

      Abstract: External root resorption is the destruction of the outer surface of the tooth by odontoclasts. In some cases, although the cause is unknown, localized inflammatory lesions, tumors and cysts, orthodontic applications, occlusal forces, dental traumas may cause external root resorption. Materials used in the treatment of external root resorption should be biocompatible, support the regeneration of damaged tissues and provide three-dimensional sealing of the root canal. With the bioactive materials produced for this purpose, it is possible to perform sealed root canal treatments even in complex pathological conditions such as root resorption. Mineral trioxide aggregate (MTA) is one of the bioactive materials used in the treatment of external root resorptions. In this case report, two cases diagnosed with root resorption and using MTA in the treatment are presented.

  • Retrospective Analysis of Cone Beam Computed Tomography Referrals in a
           Paediatric and Adolescent Patient Subgroup

    • Authors: Sevilay DEVECİ; Birsay GÜMRÜ
      Abstract: Aim: This study was aimed to evaluate the cone beam computed tomography (CBCT) indications in paediatric and adolescent patients and to investigate their compliance with the guidelines set by the DIMITRA (dentomaxillofacial paediatric imaging: an investigation toward low-dose radiation induced risks) Project.Materials and Methods: CBCT images of paediatric and adolescent patients were selected and evaluated among a total of 12494 CBCT images reviewed retrospectively. Data regarding age, gender, referring department, field of view (FOV), and CBCT indications were recorded. Based on an adaptation of European DIMITRA Project recommendations, CBCT indications were categorized as impacted teeth, trauma, orofacial clefts, dental anomalies, bone pathology, syndromes, and other indications. Follow-up CBCT examinations and incidental findings were also recorded. Data were statistically analyzed at p<0.05 significance level.Results: Most of the 1686 CBCT scans obtained from pediatric and adolescent patients were referred from the Department of Oral and Maxillofacial Radiology (31.2%), followed by the Departments of Orthodontics (25.9%) and Oral and Maxillofacial Surgery (24.6%). The most frequently requested FOV was the maxilla (35.1%) followed by the jaws (maxilla-mandible) (29.3%) and the maxillary canine-incisor region was the most commonly requested region among localised applications (83.1%). The most common indication was impacted teeth (33.5%) followed by bone pathology (32.7%). Follow-up CBCT examinations were recorded mostly for syndromes (33.3%) and orofacial clefts (20.4%).Conclusions: The use of CBCT should be justified on a patient basis and DIMITRA Project recommendations can guide dental professionals in referring CBCT in paediatric and adolescent population.

  • Periodontal treatment approach for dihydropyridine induced gingival
           overgrowth with or without drug substitution

    • Authors: Onur EROĞLU; Ece YETİŞ, Hafize ÖZTÜRK ÖZENER, Leyla KURU
      Abstract: Periodontal treatment approach for dihydropyridine induced gingival overgrowth with or without drug substitution Objectives: The aim of this study is to evaluate clinical effectiveness of nonsurgical periodontal treatment (NSPT) in patients with drug induced gingival overgrowth (DİGO) with or without drug substitution in comparison with patients presenting inflammatory GO. Material and Methods: A total of 17 patients with generalized GO were included in this clinical trial. Based on the medical physicians consultation, DIGO patients who continued to use dihydropyridine were allocated to the Group 1 (n=6), whereas patients whose drug substitution was carried out were allocated to the Group 2 (n=5). Group 3 (n=6) subjects had inflammatory GO. All study groups received NSPT for 4 sessions. At baseline and 6 weeks after NSPT, plaque index, gingival index, bleeding on probing (BOP), probing depth (PD) and, plaster model and photographic GO scores were measured. Results: NSPT resulted in significant decreases in periodontal clinical parameters in all groups (p<0.05). Intergroup comparisons of baseline measurements revealed no statistically significant differences (p>0.05) except PD value which was higher in the Group 1 compared to the Group 2 (p<0.05). Comparisons of post-NSPT data among groups exhibited statistically significant difference only between Groups 1 and 2 in the model and photographic GO scores (p<0.05).Conclusions: After the 6-week evaluation period, NSPT was found to be an effective method in reducing the severity of inflammation and size of overgrown gingival tissues in patients with DIGO and inflamatory GO. Substitution of drug causing GO provided further contribution to NSPT regarding the size of overgrown gingiva in the patients with DIGO.

  • Gingival Crevicular Blood And Its Medical Diagnostic Value

    • Authors: Hasan HATİPOĞLU
      Abstract: Dentistry makes it compulsory to work with many medical branches due to the area it covers. Another important aspect of this relationship is finding common points in treatments. Many oral and systemic disease/circumstances are in a bidirectional relationship. Patients sometimes do not have enough information about their condition or their disease may not be diagnosed. Particularly, the presence of certain systemic diseases may require modification of dental treatment. In practice, some known major disease parameters are tried to measure in the dental office. From this point of view, gingival crevicular blood is relatively studied in this regard. Gingival crevicular blood is seen during routine examination, especially in those with periodontal disease. It has been shown that this blood, which is obtained by non-invasive methods, allows some tests in the office.In this traditional review, gingival crevicular blood and its diagnostic value will be discussed.

  • Assessment of occlusal force by occlusal contact surface area and
           intensity from cast images: A preliminary study

    • Authors: Burcu BAL
      Abstract: Objectives: This study explores the use of occlusal contact surface area and intensity measures in assessing the occlusal force from articulating paper-induced dental images. Methods and materials: A pair of mandibular and maxillary dental casts obtained from a mandibular and maxillary complete denture fabricated in preclinical work was used. A 8-micron red articulating paper was inserted between the casts while they were mounted on an articulator. The occlusal force was implemented by applying 0.5 kg, and 5.0 kg weights to the articulator. The application was repeated ten times for each weight and the occlusal surface of the lower first molar tooth was imaged using a microscope from a fixed distance for each time. The images are analyzed first to identify the red-colored pixels and then to estimate the contact surface area and intensity from the pixels identified.Results: The 0.5kg and 5kg forces lead to average contact surface areas of 1.5 1.2 mm2 and 13.4 7.0 mm2 while they deliver average contact intensity of 78.0  2.9%, and 81.5  1.9%, respectively. A very strong correlation was present between the contact surface area and the force (rho= 0.87) while the correlation was moderate between the contact surface intensity and the force (rho= 0.53). Both correlations were significant (p< 0.05).Conclusion: Contact surface area and intensity measures offer potential estimates of the occlusal force. Fully automated methods for this purpose are needed to be developed.

  • Aesthetic Rehabilitation for an Adult Patient with Unilateral Cleft Lip
           and Palate: Case Report

      Abstract: Cleft lip and palate is one of the most common congenital malformations affecting the face and the jaws. These patients suffer from aesthetic, functional, social and psychologic problems. The objective of this case report is to present the prosthetic rehabilitation of the patient with unilateral cleft lip and palate, and highly aesthetic expectation. A 21-year-old patient with cleft lip and palate was referred to Marmara University Prosthesis Department due to the non-aesthetic appearance of the anterior teeth. In clinical and radiographic examination, it was observed that there was a cleft line between the maxillary left central and lateral teeth. Although there is orthodontic treatment, there is an 8 mm diastema between the teeth 21 and 22 due to the presence of the cleft line. For this reason, zirconium ceramic bridge with four members was planned to teeth 21-22 and 23 and with laminate veneer 11 and 12 of the patient. Full ceramic restorations were cemented with adhesive resin cement. After fixed prosthetic rehabilitation; the patient reported that he was satisfied with the aesthetic appearance, function and fonation. There are numerous permanent prosthetic treatment alternatives for the patients with adult cleft lip and palate. Highly aesthetic results can be achieved with fixed bridge restorations with all ceramic systems.

           Indirect Resin Restorations

    • Authors: Duygu TUNCER; Selin POLATOĞLU, Hilal ÜNVER, Çiğdem ÇELİK
      Abstract: Objectives: The aim of this study was to evaluate the effect of different polymerization procedures on color stability of indirect resin restorations. Materials and Methods: 288 disk-shaped specimens of resin composites(Filtek Z250, Gradia Plus, Ceramage, GrandioSO) were prepared with laboratory and chairside curing device(I.Labolight Duo/II. Elipar S10). Then, baseline color measurements were performed. Specimens of each composite were randomly divided into three subgroups according to staining solution(coffee, black tea and distilled water as control group)(n=12). Color measurements were performed and ΔE values were calculated. The data were evaluated by using ANOVA for repeated measures and multiple comparisons were determined by Bonferroni test(p0.05). Results: Staining increased over time for all groups and coffee showed the highest staining potential(p<0.05). Polymerization procedures also affected color stability(p<0.05). Conclusion: It was concluded that different polymerization procedures and staining solutions might affect color stability of resin composites tested.

  • Numb Chin Syndrome Associated With Residual Ridge Resorption In Edentulous
           Mandible: Report Of A Case

    • Authors: Melda Pelin AKKİTAP; Birsay GÜMRÜ, Sevilay DEVECİ, Ender İDMAN
      Abstract: Residual ridge resorption (RRR), which follows a chronic, progressive, and irreversible course, is due to alveolar remodeling under the influence of cumulative effect of many local and systemic factors after tooth extraction. Decreased height of the mandible leads to change in the location of the mental foramina at the crest of the residual ridge and also subjective pain and paresthesia under mandibular dentures due to the pressure caused by the denture, a phenomenon known as “numb chin syndrome”. In this article, a case with excessive mandibular RRR is presented along with clinical and radiological findings.Clinical and radiological examinations of a 61-year-old female patient who admitted to our clinic with tenderness and soreness complaints in the right mandibular edentulous alveolar ridge were performed. Intraoral examination revealed severe resorption of the edentulous mandibular alveolar ridge. The right mental foramen was observed to be close to the alveolar crest in panoramic radiograph. Cone beam computed tomography scan confirmed the severe mandibular atrophy and mental foramen exposure at the top of the alveolar crest, clearly revealing the cause of the patient’s tenderness and soreness complaints.In the edentulous mandible, RRR predisposes the mental nerve to injury because of the proximity of the mental foramina to the alveolar crest. Chronic pressure on the mental nerve may cause pain in the mental nerve distribution region and numbness in the lower lip. Radiographic examinations should definitely be considered as an indispensable component of diagnosis and prosthetic treatment planning, especially in edentulous patients with RRR.

  • Use of Botulinum Toxin In The Treatment of Temporomandibular Disorders

    • Authors: Hatice Banu UYSAL ÖZEL; Yılmaz Umut ASLAN, Erkan SANCAKLI
      Abstract: Temporomandibular disorder (TMD) is a term used to describe disorders that involve the temporomandibular joint, the masticatory muscles and associated structures. Patients with TMD have symptoms such as tenderness and pain in the joints and masticatory muscles, limitation in mouth opening, and joint sounds. TMD treatment usually requires a multidisciplinary approach and reversible conservative treatment options should be the first choice. Botulinum toxin (BoNT) injection, which is one of these treatment options, is used in many areas of dentistry, as well as in various TMD treatments. BoNT is a neurotoxin that inhibits the release of acetylcholine at the neuromuscular junction and inhibits contraction of the target muscle. In the treatment of TMD, BoNT is applied to reduce muscle tension that causes various temporomandibular diseases and symptoms. In this review, the place of BoNT injection in TMD treatment, its application technique and its effect on symptoms are evaluated in the light of literature.
