Abstract: Background- Excessive accumulation of fat results into obesity. Obesity further have an adverse effect on health as it has been seen to be associated with diabetes mellitus, hypertension, heart disease like coronary artery disease, cerebrovascular disease such as hemorrhagic and ischemic stroke, metabolic syndrome like insulin resistance, some cancers such as cancer of esophagus, thyroid, kidney, uterus, colon and breast, and psychosocial problems. Also, obesity is considered to be a risk factor for periodontitis which is an inflammation of supporting periodontal structures around the tooth which results from the complex interaction between pathogenic bacteria and the host immune response. However, the impact of obesity on different severity of periodontal disease is not evaluated in rural population. Aim: To evaluate the relationship between obesity and the severity of periodontal disease in Rural population. Methodology: A total 400 obese subjects will be included in the study. Biometric parameters like age, weight, height, waist and neck circumference, subcutaneous skin fold will be evaluated. Also periodontal parameters like Plaque index (PI), Papillary bleeding index (PBI), Probing pocket depth (PPD), Clinical attachment level (CAL) and Gingival recession (REC) will be evaluated and co-relation between these parameters will be carried out. Results: A statistically significant association will be observed between BMI and periodontitis of overweight and obese study individuals having periodontitis. A positive co-relation will be observed between biometric parameters and periodontal status of obese individual. Conclusion: A significant association will be observed between BMI and periodontitis of overweight and obese study individuals having periodontitis in rural population.
