Abstract
Objectives : The aim of the trial was to study the effect of plaque control(tooth brushing instruction) for oral
health improvement on periodontitis patients.

Methods : 30 patients(35~65 years) with advanced periodontal disease were subjected to a baseline examination
including assessment of oral hygiene status(O¡¯leary index), gingival condition(bleeding). the assessment were repeated after 2, 4, 6 weeks. cognitive, behavioral and clinical outcomes were assessed in the primary care setting by questionnaire and clinical oral examination.

Results : The oral hygiene status expressed as the individual mean percentage of tooth surfaces with plaque
59.3% at baseline and 21.2% after 6 weeks(p£¼0.001). The gingival bleeding status expressed as the individual mean point of interdental papilla 3.8 at baseline and 1.9 after 6 weeks(p£¼0.001). Also, the patients self-assessment about correct tooth brushing behavior was 3.9(5-point likert scales), satisfaction of plan practices 4.1(5- point likert scales), efficacy of tooth brushing instruction 8.7(10-point likert scales). Patients wanted to continuous participation.

Conclusions : A verification of effect after individualized oral health instruction and repeated dental plaque control
represented to significance on plaque control score, oral care practice and oral health recognition. The important oral care step against periodontal disease is to establish good oral health habits.
