Evaluation of the possible relationship between obesity and temporomandibular joint disorders.

OBJECTIVES: The objective of this study is to question the existence of a possible relationship between obesity and temporomandibular joint disorders. SUBJECTS AND METHODS: A total of 256 healthy subjects were included in the study. While the body mass index was used for the detection of obesity, Fonseca anamnestic index was used for the detection of temporomandibular joint disorders. The relationship between body mass index and temporomandibular joint disorders frequency was investigated. Values of P< 0.05 were considered statistically significant. RESULTS: There were 136 female (53.1%) and 120 male (46.9%) subjects. The mean age was 39.02 ± 10.62. 41.4% of the subjects were in normal weight, 32.4% were overweight and 26.1% were obese. The prevalence of temporomandibular joint disorders was 73.8%. CONCLUSIONS: There was no statistically significant difference between body mass index and temporomandibular joint disorders frequency, but further larger studies will give more accurate outcomes.

Radiographic assessment of the relationship between root canal treatment quality, coronal restoration quality, and periapical status.

OBJECTIVE: The aim of this cross-sectional study was to assess the prevalence of apical periodontitis in root canal treated teeth in Turkish subpopulation and to evaluate the effects of both coronal restoration quality and root canal treatment (RCT) quality on apical periodontitis. MATERIALS AND METHODS: Panoramic images of individuals who applied to our department for different diagnostic reasons were randomly and retrospectively scanned. Total RCT number, RCT quality, type of coronal restoration, restoration quality, periapical status, and total number of teeth were recorded. The criteria used for coronal restorations quality and RCT quality were defined by De Moor et al. and slightly modified by Gunduz et al. Periapical status was assessed by the periapical index developed by Orstavik et al. Pearson's Chi-square test was used for statistical analysis, and the intraobserver agreements were assessed by Kappa coefficients. Values of P < 0.05 were accepted to be meaningful. RESULTS: The total examined teeth number was 6064, of which had 541 (8.9%) RCT. The prevelance of apical periodontitis was 40.5%. The number of adequate RCT was 178 (32.9%), and 138 (77.5%) of them were healthy. The number of adequate coronal restoration was 334, and 62.3% of them were healthy. For the cases that have adequate coronal restorations, there was statistically significant relationship between adequate RCT and periapical status (P < 0.001). CONCLUSION: The prevelance of apical periodontitis was 40.5% and there was statistically significant relationship between adequate RCT and periapical status.
