변형 바스법을 이용한 칫솔질 교습 후 치면세균막 관리능력 향상에 대한 평가

Abstract

Objectives: Periodontal disease is chronic bacterial infection caused by supragingival and subgingival plaque. It could be prevented or arrested by measures directed toward the control of bacterial plaque formation. Therefore, the importance of oral health education and toothbrushing instruction is being emphasized. In particularly, individually tailored oral health educational program have a more positive impact on oral hygiene behavior. The aim of this study is to evaluate patients' plaque control ability after tooth brushing instruction of modified Bass technique and to suggest appropriate oral hygiene management methods for each patient.

Materials and Methods: Patients who wanted to participate in clinical testing for the improvement of plaque control ability were selected. The interval of oral health education and toothbrushing instruction for the 60 subjects was randomly assigned into 1 week, 2 week, and 3 week. Each group was subdivided into ① demonstration only ② demonstration with chairside practice. In addition, subjects were categorized into good, fair, and poor group by dividing Turesky modification of Quigley-Hein plaque index(TQHI) into three equal parts according to their initial plaque control ability. Subjects were examined five times. During the 1st visit, change in attitude toward toothbrushing was evaluated through questionnaire prior to oral health education. Plaque evaluation, oral health education, and toothbrushing instruction for modified Bass technique were conducted consecutively. At the 2nd, 3rd, 4th visit, plaque was evaluated and the subjects were motivated through the instruction. At the 5th visit, attitude toward toothbrushing after oral health education was assessed through questionnaire and plaque was evaluated. The questionnaire survey was conducted to figure out the change in attitude toward toothbrushing. TQHI was used to evaluate plaque.

Results: From intragroup analysis of education interval, plaque index had a tendency to be improved gradually from the 1st visit to the 5th visit. From intergroup analysis, there were no statistically significant differences among 1-week, 2-week, and 3-week interval. Demonstration with chairside practice group showed statistically significant improvement of plaque index compared with demonstration only group. In good, fair, and poor group, plaque index was improved gradually from the 1st visit to the 5th visit. Change of plaque index increased as plaque control ability decreased. As plaque control ability is lower, the percentage of subjects with improved attitude was raised more through oral health education and toothbrushing instruction

CONCLUSION: When oral health education and toothbrushing instruction are conducted for removing plaque effectively, the results of this study is thought to be helpful for suggesting appropriate oral hygiene management methods for each patient to improve plaque control ability.
