One hundred outpatients were exmined at the preparatory stage commencing from initial examination till second time of 7 to 10 days time lapse as to the improvement degree by the assessment of plaque index and gingival index. The correlation between plaque index and gingival index was also examined. 1. There was a difference between male and female as to plaque index at the time of initial examination for these outpatients and it was found male showed higher score to female by approximatatey 1.2-1.3 times. Ragarding gingival index, male was also found to show higher score than female. 2. Difference was found in the toothbrushing group between Rolling method and Scrubbing method group as to the change of plaque index from initial examination till second one. Rolling method group showed superior score of 35.5% to that of Scrubbing method group of 20.0% on improvement rate. On the other hand, there was no difference between both groups as to gingival index. 3. Regarding the improvement rate of other factors are as follows; Particularly, improvement rate in 40-49 was the worst either plaque index or gingival index. plaque index Rolling method>Scrubbing method ** male=female N.S. 20-29≧50-59≧30-39>40-49 N.S. maxilla<mandibular ** ligual. palatal≧buccal. labial N.S. right=anterior=left N.S. gingival index Rolling method=Scurubbing method N.S. male<female ** 50-59≧30-39≧20-29>40-49^<**> maxilla=mandibular N.S. lingual. palatal=buccal. labial N.S. right=anterior=left N.S. ^<**>: P<0.01 N.S.: not significant 4. Statistical significance was shown between plaque index and gingival index at initial and second examination. Each coefficient of correlation (r) was 0.664 (n=100) at first and 0.513 (n=100) at second examination respectively. The coefficient of correlation draw from individual subject was r=0.298 (n=100) between plaque index and gingival index as to the ratio of improvement, which was shown statistical significance. As above findings are obtained from 100 outpatients under a settled condition, it seems unlikely to generalize it into a general theory, but further information in proximity to real score which will be utilized for oral initial therapy plan as a preparatory phase of periodontal treatment when number of subjects is increased. This research work is, therefore, one step toward future prospect of this field.
