RESUMO
OBJECTIVES: To compare the efficacy and patient-reported outcome measures of oral hygiene instruction methods for calibrated interdental brush. MATERIALS AND METHODS: A total of 60 participants, with 30 each in control and test group, participated in the study. Clinical examination included gingival index, full mouth bleeding scores and approximal plaque index. Supragingival scaling was performed. Interdental access probe was used to assess the size of interdental brush and corresponding interdental brush were given to the participants. For the control group, oral hygiene instructions were given through demonstration with model and video. For the test group, oral hygiene instructions were given through 'Touch-to-Teach' method. At 4-week follow-up, oral hygiene instructions were repeated to respective groups. After 3 months, clinical examination was done and exit survey on patient-reported outcome measures was administered. Statistical analysis was done. RESULTS: Intergroup comparison of gingival index, full mouth bleeding index and approximal plaque index showed statistically significant difference between test and control group. 'Touch-to-Teach' method of oral hygiene instruction was found to be 'Good'. Acceptance of interdental brush was regarded to be 'Good'. CONCLUSION: Within limitations of the study, Touch-to-Teach method of oral hygiene instruction method was found to be effective and more acceptable and participants used the interdental brush regularly.
