The relationship between parents' oral hygiene knowledge and children with Down Syndrome's oral hygiene via OHI-S

Abstract

Background: Down Syndrome (DS) is a genetic disorder that causes structural, functional anomalies, and intellectual disability. The common oral hygiene problems found in DS children are gingivitis, periodontal problems, pain, infection, and problems with the masticatory system. This study explored the relationship between parents' oral hygiene knowledge and oral hygiene of children with DS. Method: This was an observational analytical study. To assess parents' oral hygiene knowledge, a questionnaire consisting of 25 questions was distributed to 100 parents whose DS children in POTADS (Down Syndrome Parents Association) Surabaya. To assess the DS children's oral hygiene, dental exams were performed to calculate the individual Oral Hygiene Index-Simplified (OHI-S) scores by dividing the sum of the individual debris and calculus scores by six (the number of teeth examined). The data were analysed using regression analysis. Results: There was a significant and strong inverse relationship between parents’ oral hygiene knowledge and DS children’s oral hygiene. Parents’ oral hygiene knowledge affected DS children’s oral hygiene. The results of the regression analysis indicated that a 1% increase in parents' knowledge caused a reduction in the OHI-S score to 7.377. Conclusion: A significant inverse relationship between parents’ oral hygiene knowledge and DS children’s oral hygiene was observed in this study. Further studies could be conducted to determine other variables that my influence both parents’ oral hygiene knowledge and DS children’s oral hygiene.
