It is possible that PAT is a more frequent condition than is commonly perceived. In differential diagnosis of suspected cases or in cases for which surgical treatment is planned, panoramic radiographs should be supplemented with CBCT.

CBCT detected more cases of PIR than panoramic radiography. The mandibular third permanent molar was the most commonly affected tooth.

A 29-year-old systemically healthy female patient presented to our department. Cone-beam computed tomographic images showed multiple well-defined sclerotic masses with radiolucent border in both right and left molar regions of the mandible. These sclerotic masses were surrounded by a thin radiolucent border. We diagnosed the present pathology as florid cemento-osseous dysplasia and decided to follow the patient without taking biopsy. For the patient, who did not have any clinical complaints, radiographic followupis recommended twice a year. The responsibility of the dentist is to ensure the follow-up of the diagnosed patients and take necessary measures for preventing the infections.

Objective:To evaluate if there is a relationship between findings of carotid artery calcification (CAC) and periodontal risk in nonsmoker subjects by using panoramic radiographs (DPR).Materials and Methods:A total of 1146 DPRs were investigated. Gender, age, severity of bone loss, tooth loss, periodontal risk, and findings of carotid calcification were recorded. The periodontal risk was evaluated and classified according to the degree of alveolar bone loss.Results:CAC was diagnosed in %13.6 (n: 156) of DPRs. Of 1146 patients, 338 (29.5%) had low, 668 (60%) had moderate, and 120 (10.5%) had high periodontal risk. A statistically significant relation was observed between carotid calcification and periodontal risk.Conclusion:Positive findings of carotid calcification may be related with periodontal problems. Clinicians must be careful about diagnosing CACs on DPRs during routine examinations. In the case of positive findings of CAC and periodontitis together, the patient may be consulted to a specialist for further investigation.

Osteoarthritis is a degenerative joint disorder resulting in destruction of articular cartilage, osteophyte formation, and subchondral bone sclerosis. In recent years, numerous genetic factors have been identified and implicated in osteoarthritis. The aim of the current study was to examine the influence of methylenetetrahydrofolate reductase (MTHFR) gene C677T mutation and angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) variations on the risk of osteoarthritis.Genomic DNA is obtained from 421 persons (221 patients with osteoarthritis and 200 healthy controls). ACE gene I/D polymorphism genotypes were determined using polymerase chain reaction using I and D allele-specific primers. The MTHFR C677T mutation was analyzed by polymerase chain reaction (PCR) based restriction fragment length polymorphism (RFLP) methods. We found significant difference between the groups with respect to both ACE and MTHFR genotype distributions (p < 0.001, p < 0.001 respectively). Our study suggests that ACE gene DD genotype and MTHFR gene CC genotype could be used as genetic markers in osteoarthritis in Turkish study populations.

The results indicate that the quality of both the root filling and restoration were found to have impact on the periapical health of root-filled teeth.

Aims:The aims of our study were to investigate the distribution of cervical vertebrae anomalies (CVAs) among dental Angle Class I, II, and III malocclusions in Turkish population and whether a correlation between CVA and dental malocclusion.Materials and Methods:The study was performed on lateral cephalometric radiographs which were taken at the Department of Orthodontics, Faculty of Dentistry, Kirikkale University. The final sample of 318 orthodontic patients was included in the study. Dental malocclusions were performed according to Angle classification. CVAs were categorized: (1) fusion and (2) posterior arch deficiency (PAD). The Chi-square test was used to the analysis of the potential differences among dental malocclusions.Results:The final sample of 318 patients was examined. CVA was observed in 42 individuals (of 26 [8.17%] had fusion and 16 [5.03%] had PAD), with a frequency of 13.2%. Of the 26 fusion defect, 8 (30.7%) had Angle Class I, 8 (30.7%) had Angle Class II, and 10 (38.4%) had Angle Class III malocclusion. Of the 16 PAD, 8 (50%) had Angle Class I, 8 (50%) had Angle Class II but no patients with Angle Class III malocclusion was observed. The distribution of dental malocclusions regarding CVA was not statistically significant (P = 0.076). Of these 42 individuals with CVA, 52.3% (15 fusions and 7 PAD) were females and 47.7% (11 fusions and 9 PAD) were males.Conclusion:In our study, the prevalence of fusion and PAD were found 8.1% and 5.0% in Turkish population, respectively. Besides, no statistically significant correlation between CVA and Angle Class I, II, and III malocclusions were found. Our findings support the studies showing no gender dimorphism.
