Obesity, a common metabolic disorder, is a condition for the development of chronic diseases, such as hypertension, diabetes mellitus, cardiovascular and cerebrovascular diseases. The present study evaluates the prevalence of periodontal diseases in Romania and their association with obesity, as a risk factor. This cross-sectional study included 170 subjects aged between 18-65, with healthy periodontal status, gingivitis, aggressive periodontitis and chronic periodontitis. All subjects completed the questionnaire with independent variables: age, education, socio-economic status, oral hygiene habits, smoking habit, the presence of any systemic diseases. Periodontal examination included: plaque index, gingival index, probing depth, clinical attachment level. Body mass index (BMI) and waist circumference (WC) were measured. Statistically significant correlations were found between periodontal diseases and BMI and WC: according to BMI 30.5% were obese, and 42.5% had high WC. 51.9% of obese participants had chronic periodontitis. Gingivitis and initial periodontitis do not influence BMI and WC, only the chronic periodontitis remained significantly associated with obesity. Our study suggests that there is an association between chronic periodontitis and BMI- defined obesity or WC, but further prospective studies should be carried on to establish the extent of it. The prevention and management of obesity may represent an approach to control periodontal health. Our study evaluates the prevalence of periodontal diseases in Romania and their association with obesity, as a risk factor.

Obesity is a complex and multifactorial disease. Its relationship with periodontal disease and other chronic diseases is well documented but the underlying mechanism is under investigation. It is quite difficult to say whether obesity predisposes an individual to periodontal disease or periodontal disease affects lipid metabolism, or both. The purpose of the study consists in evaluating the periodontal clinical parameters in obese patients diagnosed with chronic periodontitis, before and after surgical treatment of obesity through the procedure called gastric sleeve Our study consists of a group of 38 patients diagnosed with morbid obesity who were surgically treated by gastric sleeve surgery at the Surgery Department II of the County Emergency Clinical Hospital Targu Mures. Patients with pre-operative and psot-operative examination at 3 months and 6 months respectively in which either periodontal index were index of plaque, index of probing depth and index of bleeding on probing. Correlations between parondontal clinical indexes (PD, PI, BOP) were calculated before and after gastric sleeve at 3 and 6 months respectively. The bleeding on probing index (BOP) reveals a complete decrease in postoperative bleeding time. Patients at 3 months experience minor bleeding during testing and no longer showing bleeding at 6 months. The results provide evidence that there is a link between obesity and periodontitis, however the risk factors that aggravate these diseases should be clarified to elucidate the direction of this association.
