ABSTRACT
AIM: This study aimed to assess the effectiveness of a novel health education method-Audio Tactile Performance (ATP) technique-in maintenance of gingival health and plaque removal efficacy among institutionalized visually impaired children of Bhubaneswar city. METHODS AND RESULTS: A parallel arm, single blinded randomized controlled trial was conducted among 10- to 15-year-old visually impaired children. Clinical examinations were done by the examiner blinded to group allocations. Oral health education materials (Braille and audio) were given to control group and ATP technique was given to test group. Clinical examinations for plaque and gingival scores were assessed at baseline, 30 days interval, and 90 days interval. The trial was registered with the Clinical Trial Registry of India (CTRI/2017/05/008551). In control group, a greater plaque reduction was observed at 30 days interval (3.58 ± 1.3) when compared to baseline (2.63 ± 2.02) and 90 days interval (3.14 ± 0.88), and this difference was statistically significant. For whole mouth, in test group, a greater reduction in gingival scores was observed at 90 days interval (2.65 ± 1.64) when compared to baseline (4.58 ± 1.63) and 30 days interval (1.23 ± 2.43), and this difference was statistically significant. CONCLUSION: ATP was found to be at par with the control group (Braille and audio aids).
