Increment of caries in diabetic adults. A two-year longitudinal study

The increment of caries was monitored for two years in 30 adult diabetic and 30 healthy subjects, who received regular preventive and reparative treatment during this time. No significant differences in caries increment were found between the diabetic and control subjects, but there was a tendency for a greater increment on lingual surfaces of the teeth in the diabetic group than in the healthy subjects (P less than 0.09).
