[Studies on O'Leary's plaque control record in initial periodontal treatment. 1. Relation between PCR and different brushing methods in 1982-1986].

The purpose of this study was to investigate the effects of different methods of brushing on plaque removal, using O'Leary's plaque Control Record during initial preparation. The results were as follows: 1. There were many 40-50 year-old patients and they showed a 63.0 percent first visit Plaque Control Record average. 2. Many of the patients entering the clinic had periodontal disease in mild stages. 3. In most cases the toothbrushing methods were the Rolling method and the Modified Stillman's method. Of the patients, 73.5% achieved Plaque Control scores at the 20 percent level. 4. Of the patients who had achieved a Plaque Control Record at the 20 percent level, half of the patients instructed to brush using the Rolling method had developed moderate forms of periodontal diseases, and half of the patients instructed to use the Modified Stillman's method had developed mild forms of periodontal disease. There is a close relationship between toothbrushing methods and the progression of diseases, and this shows that Plaque removal methods should be controlled.
