Assessing the Efficacy of Manual Versus Powered Toothbrushes with Modified Bass Technique in Visually Impaired Children using Audio-Tactile Performance (Atp) Technique

Abstract

Background: To compare the effectiveness of Manual and Powered tooth brushes using the Modified Bass method in visually impaired children using the Audio Tactile Performance (ATP) technique.

Settings and design: Eighty children, aged 4 to 15, with visual disabilities and residing in institution, were selected randomly.

Methods: Baseline plaque scores were recorded using Silness & Loe plaque index. The subjects were randomly allocated into two groups: 40 participants were provided with manual soft-bristled toothbrushes and trained in the Modified Bass technique, while the other 40 used powered toothbrushes with the same method, incorporating the ATP technique. Plaque scores were re-evaluated after a 2-month period. The effectiveness of oral hygiene maintenance in these children were analysed and evaluated statistically.

Statistical analysis: To compare mean values between groups independent samples t-test is applied. To compare mean values between two time points paired t-test is applied. To compare proportions between groups Chi-Square test is applied.

Results: The difference in the plaque score before and after health education was statistically significant with a p value of  <0.001 showing that both powered tooth brush and manual toothbrushes when used for toothbrushing using the Modified Bass method of toothbrushing was very effective in plaque removal in visually impaired children.

Conclusion: The Modified Bass method of tooth brushing, when performed with both powered and manual toothbrushes, proved highly effective in improving the oral hygiene of visually impaired children when taught using the ATP technique, an effective communication tool.
