    The relationship between body mass index and stage/grade of periodontitis: a retrospective study
    (2021) Cetin, Mehtap Bilgin; Sezgin, Yasemin; Onder, Canan; Bakirarar, Batuhan; 34709456
    Objectives Possible impact of obesity on stage and grade of periodontitis has never been investigated before. This study aimed to examine the association between body mass index (BMI) and stage/grade of periodontitis per the current classification of periodontal diseases. Material and methods A total of 142 patients (82 males/60 females) were included in this study. "2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions" was taken as basis to characterize the stage/grade of periodontitis. Age, gender, smoking status, and frequency of tooth brushing, and medical data of the patients including hypertension, hyperlipidemia, BMI, and diabetes mellitus were obtained from the patient's hospital records. Obesity was assessed by BMI using the "World Health Organization" criteria. For estimating the association between BMI and periodontitis, logistic regression analysis was utilized. Results BMI was statistically associated with clinical attachment loss (CAL), probing pocket depth (PPD), Plaque index (PI), stage and grade of periodontitis, and number of remaining teeth (p < 0.001, p < 0.05, p < 0.05, p < 0.05, p < 0.001, respectively). According to the multiple regression analysis results, those with BMI 25-29.9 were found to be at risk of being stage III-IV 3.977 times (95% CI: 1.831-8.640, p < 0.001) higher than those with BMI < 25, and similarly, those with BMI >= 30 were found to be at risk of being stage III-IV 4.062 times (95% CI: 1.315-12.549, p = 0.015) higher than those with BMI < 25. No relationship was found between obesity and grade of periodontitis according to multivariate analysis. Conclusions BMI increases the likelihood of stage III and stage IV periodontitis; however, it does not have an impact on the grade of periodontitis.

    Relationship of periodontitis and edentulism to angiographically diagnosed coronary artery disease: A cross-sectional study
    (2020) Cetin, Mehtap Bilgin; Onder, Canan; Orhan, Kaan; Kumbasar, Deniz; Serdar, Muhittin Abdulkadir; Unsal, Elif; 32648271
    Objective The objective of the study is to examine the connection between oral status and the extent of coronary artery disease (CAD), which is diagnosed by angiography. Background Periodontitis and tooth loss have been linked to atherosclerosis and CAD in previous studies. However, no distinct connection was revealed due to the diversity of the results and the variety of diagnostic methods. To provide a more consistent data pool and stronger evidence, there is a need for studies with standard measurements and diagnostic criteria. Methods 309 patients, who consulted to Ankara University, Faculty of Medicine, Department of Cardiology and had coronary angiography, were enrolled to this study. Individuals were grouped based on their coronary angiography results, as CAD (+) (n = 233) and CAD (-) (n = 76). Studied parameters included cardiovascular risk factors, plaque index (PI), remaining teeth count, bleeding on probing (BOP), and probing pocket depth (PPD). Periapical radiographs were taken from teeth with >= 4 mm PPD. Oral status was categorized as periodontally healthy subjects/patients with gingivitis (Group 1), patients with periodontitis (Group 2), and edentulous subjects (Group 3). Results PI (P < 0.001), PPD (P = 0.001), BOP (P = 0.004), the number of patients with less than 10 teeth (P = 0.014), and edentulism (P = 0.009) were significantly higher in CAD (+) patients, who were mostly older (P < 0.001) and male (P < 0.001). Multivariate logistic regression analysis revealed that Group 2 (odds ratio = 2.48, 95% confidence interval = 1.24-4.95,P = 0.010) and Group 3 (odds ratio = 2.01, 95% confidence interval = 1.14-5.17,P = 0.040) were highly associated with CAD. Two and three stenosed vessels were significantly higher in Groups 2 and 3 compared to Group 1 (P = 0.003). Conclusions It was found that both edentulism and periodontitis were related to CAD.

    COMPARISON OF TWO MORPHOMETRIC LINEAR METHODS FOR ALVEOLAR BONE LOSS MEASUREMENT IN EXPERIMENTAL PERIODONTITIS
    (2019) Cetin, Mehtap Bilgin; Sezgin, Yasemin
    Aim: The aim of this study was to compare direct (performed by a dental loop, periodontal probe and digital caliper over the alveolar bone) and indirect (performed by means of a special software program on digital photographs) linear morphometric measurements to assess the alveolar bone loss. Material and methods: Thirty right mandible of Sprague Dawley rats were obtained from a previous study that induced periodontitis with ligature model. In direct measurement group, the distance between cemento -enamel junction and alveolar bone crest was evaluated by digital caliper and periodontal probe using a dental loop, whereas in indirect group by an image analysis program on digital photographs. The difference between the groups was determined by Mann-Whitney U test. Results and discussions: Mean alveolar bone loss was 1.08 +/- 0.22 mm in direct measurement group and 1.19 +/- 0.33 mm in indirect measurement group. The difference between direct and indirect groups was not statistically significant (p>0.05). Conclusions: Based on the present result, it can be concluded that, the use of direct morphometric analysis may be an alternative to indirect morphometric evaluations for measuring alveolar bone loss in rats after the induction of experimental periodontitis.
