Brief summary

Objective: To compare the impact of pictorial and video demonstration oral health educational interventions on oral hygiene status of children aged 12-16 years with hearing impairment. Methods: This randomized controlled trial spanned over the period of three months was conducted in purposively selected three schools of deaf children of Karachi. Baseline dental examination was performed to assess the dental plaque and gingival status of study participants. Dental plaque and gingival status of the participants was assessed by employing the World Health Organization recommended Plaque Index and Gingival Index. The 60 children were than randomly allocated into three interventional groups, pictorial, video and control, 20 in each group. The children were examined again after one month of oral health education provision by single examiner. Tooth brushes were provided to students at the time of baseline examination to use for one month. Collected data was subjected to statistical analysis and described in terms of Mean and Standard Deviation, mixed model ANNOVA was applied to see the difference between the mean plaque and gingival scores of three groups after one month. The p-value of \<0.05 was considered as statistically significant at the 95% confidence interval.

Detailed description

Background: Health education, conventionally and appropriately, one of the foundation of preventive dentistry, has over the years involved in significant investments of time, power, human resources and funds. Children with impaired hearing have difficulties in speaking and communication and so learning process would be longer and even more challenging than the other children without such disabilities.
