Root caries among type 2 diabetes mellitus patients visiting a hospital.

The relationship between diabetes and root caries has not received much attention in the literature; therefore the objectives of the present study were to assess the root surface caries among type 2 diabetic patients and the factors affecting root surface caries. A hospital based cross-sectional study was done among type 2 diabetics visiting a medical hospital in Bangalore. Those who had been diagnosed from at least past 5 years and were above 35 years of age were included. Among the 400 study subjects, root caries were present among 42% of the subjects. There was a statistically significant association for the presence of root caries and age (p = 0.00023), presence of periodontal pockets (p = 0.0004) and presence of loss of attachment of more than 3 mm (p < 0.0001). These findings indicate that there is a need for implementation of caries preventive measures with increasing age, and among those with compromised periodontal status among those suffering from type 2 diabetes mellitus.
