Two hundred and fifty MR and two hundred and ten N subjects were selected for the study. 1. The number of teeth which had experienced caries was 3.28 in MR and 4.66 in N. The number of decayed teeth was 2.24 in MR and 1.50 in N. The number of filled teeth was 0.71 in MR and 3.06 in N Filled teeth rate was 19.78% in MR and 58.89% in N The differences between MR and N were all significant(P<0.01). 2. Dental visit frequency of MR was 1.15 per year, and the 51.2% of MR did not visit the dental clinic for the last one year. 38.0% of MR had received the preventive dental care. 3. Toothbrushing frequency per day was 2.16 and the toothbrushing time for 78.3% of MR was less than two minutes. 51.2% of MR brushed their teeth by themselves, 13.3% did with the help of the carers, and 35.5% totally depended on the carers.
