The purpose of this study was to establish a rational system for the treatment and prevention of periodontal disease in mentally deficient adults. The subjects were 45 patients institutionalized for mental deficiency, aged 17 to 52, IQ 72 to under 14. They received oral hygiene instruction as the basis for periodontal covering 3 years. At the beginning, we educated all instructors of the institution on the importance of plaque control, brushing technique, together with the method of staining plaque and recording plaque charts. The instructors taught the mentally deficient adults the brushing method in the form of daily compulsory trainings for a trainings period of one year. For the subsequent 2 years, they changed the instructive system from compulsory trainings to free trainings after lunch. The plaque accumlation rate (PI. R), gingival index (G.I) and pathological pocket rate (Po. R) were evaluated on every tooth except 3rd molar and crowned tooth every 6 months for 3 years. The subjects were divided into A, B group by the PI. R at the first 6 months examination, i. e. A group was over PI. R 26%, B group was under PL R 25%. Scaling and root planing were done in B group for 6-12 months and 30-36 months, and A group for 30-36 months only. The results were as follows ; 1) PI. R was significantly improved during the first 6 months (51.9 to 31.6%). However, immediately after the instructive system was changed, PI. R became sligtly worse, but improved again for 18-36 months by re-instruction. 2) G. I was significantly improved during the first 6 months (1.37 to 0.79). In the B group which was treated by scaling for 6-12 months, G. I was remarkably improved again at 12 months, but in the A group, by oral hygiene instruction only, G. I was gradually improved. 3) Po. R was significantly improved during the first one year (32.1 to 12.4), and after the instruction system was changed, it became sligtly worse, but improved by scaling between 30-36 months. 4) The number of subjects, who required accistance from instruction in brushing, decreased from 10 to 6 after one year, on the other hand those who needed no assistance increased from 10 to 20. The results of this study shows that oral hygiene instruction and scaling are very important for mentally deficient adults. It was shown that for plaque control daily instruction is important and the brushing method traning should be compulsory and repeated without fail.
