Comparative evaluation of two audio sensory methods on oral hygiene maintenance in visually impaired children.

AIMS

To evaluate and compare the efficacy of manual toothbrush, audio-tactile performance (ATP) method, and musical toothbrush on plaque control and oral hygiene maintenance in visually impaired children.

METHODS AND RESULTS

The current observational study included 60 visually impaired children aged 9-16 years who were randomly divided into 3 groups, each with 20 children receiving oral hygiene instructions in different modes: Group 1 (Control) manual toothbrush, Group 2 (ATP) audio-tactile performance method with a manual toothbrush, and Group 3 musical toothbrush. Both manual (groups 1 and 2) and musical toothbrushes (Group 3) were changed after 3 months for better efficiency. Oral hygiene index simplified (OHI-S) and Rustogi Modified Navy Plaque Index (RMNPI) plaque scores were recorded at baseline, at the end of 1, 3, and 6 months. The collected data were statistically analysed using SPSS version 21. The intra- and inter-group comparisons were analysed using one-way ANOVA, and the multiple group comparisons were analysed using the Tukey HSD test. In intragroup comparisons from baseline to 6 months, both OHI-S and RMNPI plaque scores were reduced for group 3, only OHI-S plaque scores were reduced for group 2. Intergroup comparisons revealed a statistically high significant difference in OHI-S plaque scores from baseline to 6 months and RMNPI plaque scores from 1 to 6 months.

CONCLUSION

The motivation and education with musical toothbrushes and audio-tactile performance (ATP) method could aid in the improvement of oral hygiene maintenance of visually impaired children.
