The total mean values of DMFS among hyperthyroid group was (36.631±2.659), hypothyroid group (38.101±2.235), and symptomatic group (30.973 ± 3.830). Caries experience was found to increase with advancing age with highly statistically significant differences and increase in mean value of DMFT and DMFS by increase the duration of illness in both hypothyroid and hyperthyroid group without statistically significant differences.
