Abstract

Objectives: We aimed to investigate oral health, oral hygiene, and associated factors in children with visual impairment aged 7-11 years.

Materials and methods: This cross-sectional study was conducted on 47 children with visual impairment aged 7-11 years who were selected from all three schools available for visually impaired children in Tehran in December 2018. Questions regarding age, gender, status of visual impairment, level of education of the parents, self-reported dental and gingival health, oral health, and dietary habits were asked face-to-face using the World Health Organization oral health questionnaire for children. The decayed, missing, and filled teeth index for both primary (dmft) and permanent (DMFT) dentitions was determined by clinical examination. Simplified Oral Hygiene Index (OHI-S), and bleeding on probing (BOP) were also assessed. Linear and logistic regression tests were used for statistical analysis.

Results: Over 70% of the children were satisfied with their dental and gingival health. Daily brushing was reported by 70.2%. Over half of the children reported daily consumption of fruits and jam/honey. The mean dmft and DMFT scores were 2.85±3.21 and 0.81±1.15, respectively. The mean OHI-S was 2.09±0.58. Also, 57.4% and 34% of the children had unrestored caries in their primary and permanent teeth, respectively. BOP was seen in 78.7% of the children. A significant correlation was observed between toothache in the past 12 months and dmft score (P<0.003). Daily tooth brushing was inversely correlated with OHI-S index (P=0.02).

Conclusion: The results highlight an urgent need for implementation of oral health programs for visually impaired children.
