Abstract
Aim: To assess the effectiveness of Braille and audio tactile performance (ATP) aid in improving oral hygiene status of visually impaired students. Materials and Methods: Randomized interventional study was conducted among 220 institutionalized visually impaired students aged 8–18 years for a period of 9 months. Study participants were divided into two groups, Group I (Braille) and Group II (ATP). Oral hygiene index-simplified (OHI-S) was used to assess their oral hygiene status at baseline and post intervention at the end of 9 months. Health education as intervention was given in Braille and ATP aid once in 2 months. Pre- and post-intervention OHI-S scores were compared. Results: The mean OHI-S scores in Group I reduced from 1.83 ± 0.68 to 1.79 ± 0.67, and P value was not found to be statistically significant (P = 0.21). Group II OHI-S scores reduced from 1.8 ± 0.66 to 1.75 ± 0.65, and P value was found to be statistically significant (P = 0.03). Conclusion: This study concluded visually impaired students can maintain an acceptable level of oral hygiene when taught using ATP technique.
