The Influence of Insulin Dependent Diabetes Mellitus on Dental Caries and Salivary Flow

Abstract

Objective . To assess whether or not there was any change in the dental caries and rate of salivary flow of patients with Insulin Dependent Diabetes Mellitus (IDDM) and the contribution of salivary flow to caries risk in IDDM. Setting . Department of Endocrinology, MS Ramaiah Hospital, Bangalore, India. Design . A comparative cross-sectional descriptive type. Materials and Methods . The sample consisted of two groups: 140 diabetic group (mean age 14.8 yr) and 140 nondiabetic group (mean age 13.7 yr). Dental caries by dmf(t) and dmf(s) indices for primary dentition and DMF(T) and DMF(S) indices was used in permanent dentition to assess the dental caries experience. Both stimulated and unstimulated salivary flow rate were assessed after collection of saliva. Results . In diabetic group 76% had carious lesion and in nondiabetic group 85.3% had carious lesion. Diabetics have lower mean DMFT, DMFS, dmft, and dmfs compared to the nondiabetic group. Diminished unstimulated and stimulated salivary flow rate in diabetic than nondiabetic group. Conclusions . The findings obtained conclude that even though there was reduced salivary flow rate in diabetic group the caries prevalence was low.
