Effectiveness of supervised oral health maintenance in hearing impaired and mute children- A parallel randomized controlled trial.

Abstract

Context:Individuals with special needs may have great limitations in oral hygiene performance due to their potential motor, sensory, and intellectual disabilities. Thus, oral health care utilization is low among the disabled people. Hearing disorders affect the general behavior and impair the level of social functioning.Objectives:The present study was conducted to assess the dental health outcomes following supervised tooth brushing among institutionalized hearing impaired and mute children in Jaipur, Rajasthan.Materials and Methods:The study followed a single-blind, parallel, and randomized controlled design. A total of 315 students were divided into three groups of 105 children each. Group A included resident students, who underwent supervised tooth brushing under the supervision of their parents. The non-resident students were further divided into two groups: Group B and Group C. Group B children were under the supervision of a caregiver and Group C children were under the supervision of both investigator and caregiver.Results:There was an average reduction in plaque score during the subsequent second follow-up conducted 3 weeks after the start of the study and in the final follow-up conducted at 6 weeks. There was also a marked reduction in the gingival index scores in all the three groups.Conclusion:The program of teacher and parent supervised toothbrushing with fluoride toothpaste can be safely targeted to socially deprived communities and can enable a significant reduction in plaque and gingival scores. Thus, an important principle of oral health education is the active involvement of parents and caregivers.
