Background: Associations between obesity and several chronic inflammatory diseases are emerging. Research from some parts of the world has also indicated that a relationship between periodontal disease and obesity is possible. The aim of the present study was to determine the association of obesity with periodontal disease in a semi urban Indian population. Methods: Body Mass Index (BMI) was determined for 323 patients visiting the department of Periodontics. Other demographic variables such as age, gender, stress, educational background and smoking were also considered. Clinical examination of the periodontal health was assessed using the Plaque index (PI), the Gingival index (GI) and the Community Periodontal Index (CPI). Results: No association was obtained between BMI and periodontitis. Other demographic variables were also not significantly related. Lower gingival index scores, were significantly associated with better periodontal health. Conclusion: Good oral hygiene and normal body weight can reduce the overall inflammatory burden, thereby reducing the risk for development of periodontal disease.

Background: Molar incisor hypomineralization (MIH) describes the clinical picture of hypomineralization of systemic origin affecting one or more first permanent molar and incisors. Although the reported prevalence of MIH ranges from 2.4% to 40.2% worldwide, very little data is available from Nepal.Objective: To assess the prevalence of MIH in children aged 7-13 years of Biratnagar, Nepal. Study design:This cross-sectional descriptive study consisted of 567 children aged 7-13 years selected by cluster sampling method. Examinations were performed by one calibrated pediatric dentist. The European Academy of Pediatric Dentistry (EAPD) 2003 criteria was used for diagnosis. Results:The prevalence of MIH was 8.6% in the age group of 7 to 13 years. The prevalence of MIH was 8.33% in males and 9.01% in females. The prevalence and severity of MIH increased with increase in age. The prevalence of MIH was 10.54% in the age group of 10 to 13 years as compared to 5.95% in the age group of 7-9 years. Conclusion:The prevalence of MIH was 8.6% in the age group of 7 to 13 years. Developmental dental defects hold significance for scientists and practitioners from both medicine and dentistry. Dental interest has recently swung toward Molar Hypomineralisation. MIH imposes a significant burden on global health and has potential to become medically preventable, being linked to infantile illness.
