Evaluation of a specially-designed educational and interventional programme on institutionalized visually impaired children: A prospective interventional study.

Abstract

The aim of this study was to design, implement, and to evaluate the success of an oral health care programme specially designed for visually impaired children over a 12-month period. A structured questionnaire collected information regarding oral health knowledge and practices of the study population. A specially designed oral health education programme was conducted for the children and their teachers and reinforced after 1, 3, 6, 9, and 12 months. The oral health status of the children was assessed and scored at baseline examination and after each follow-up visit. Independent t-test and paired t-test were used for comparison of scores. Spearman's correlation test was used to measure the correlation between knowledge and practices scores with oral hygiene status. The study population (5-16 years) had good knowledge about oral health which, however, did not translate into everyday practices. The overall oral hygiene scores declined from 2.06 ± 1.20 at the preliminary examination to 1.24±0.79 at the end of 12 months (p<0.001). The customized oral-health education programme was efficacious in improving the oral health of the visually impaired children, and the repetition and reinforcement components of this dental health education programme were of significant value in enhancing their oral health.
