Gustatory Sensitivity And Oral Health In Congenitally Visually Impaired Children: A Randomized Controlled Trial

Abstract

Objectives

Limited access to visual sensation of visually impaired children causes difficulties in maintaining dental hygiene, resulting in a higher occurrence of caries and gingivitis. Traditional oral hygiene techniques rely on the visual sense, limiting their effectiveness in reducing plaque. The current study aims to assess the efficacy of unique natural flavored dentifrices in improving oral hygiene through sensory stimulation, particularly aroma and taste.

Methods

A single-blind, parallel-group, randomized controlled control trial was carried out on 68 visually impaired children aged 6-15 years at Manik Prabhu Academy for the Blind in Raichur, India, using CONSORT guidelines. Participants were assigned to flavored or unflavored toothpaste groups based on the flavors' tactile, olfactory, and taste experience. Plaque Index was recorded at baseline, 21, and 90 days. Statistical analysis used SPSS version 20, with significance set at p<0.05.

Results

When an unpaired t-test is performed both groups showed a decrease in plaque scores over time. However, the flavored toothpaste group showed considerably higher decreases in PI at 21 and 90 days (p<0.05). There were no adverse consequences noted.

Conclusion

Flavored toothpaste improves oral hygiene in visually impaired children by encouraging sensory engagement. It increases compliance and brushing efficiency, making it a viable alternative for gingivitis management in this population.
