Abstract
Plaque control would be the best and final prevention method against periodontal disease. We have demonstrated the effective motivating method for the patients to clean their teeth in the clinical practice. The purpose of this study is to know whether the method is available in public health or not.
Thirty three volunteers (aged 19-51 years) participated in this study. Indices concerning gingivitis, tooth mobility and oral hygiene index were scored at 0-week, 2-week, 3-month and 1-year. And at the same time, the subjects were given intraoral instruction of tooth brushing in cleaning the interdental areas.
As a whole, all the indices except for tooth mobility showed remarkable improvements at 2-week, and well maintained even after 1-year. The subjects were divided into two groups according to the methods they brushed their teeth. Those subjects who answered that they brushed their teeth by the recommended method every day showed a good maintenance of the scores after one year, but not the other subjects.
The result may give the possibility to apply the method of tooth brushing instruction (intraoral method) in public health for the prevention of periodontal disease.
