Impacts of oligodontia on oral health-related quality of life reported by affected children and their parents

Abstract

Summary Background Oligodontia (agenesis of six or more permanent teeth) affects functional, emotional, and social aspects of an individual’s life. Few published studies have evaluated oral health-related quality of life (OHRQoL) in children with oligodontia and very limited have compared the child and parental perceptions. Methods Thirty-five 8- to 18-year-old patients with oligodontia (10 M, 25 F; mean age: 12.4 ± 2.9 years; mean number of permanent teeth missing due to agenesis: 8.9 ± 3.2) recruited from The Hospital for Sick Children, Toronto, and Holland Bloorview Kids Rehabilitation Hospital, Toronto, and their parents completed the short format of Child Perception Questionnaire (CPQ11–14) and the Parent Child Perception Questionnaire, respectively. Results Children reported significantly worse overall CPQ score than their parents. Correlations between children’s and parents’ overall CPQ score, oral symptoms and functional limitations, and social well-being were not statistically significant. However, as children’s emotional well-being score increased, parents’ score also increased. There was no association between child CPQ score and age, gender, number, and location of permanent tooth agenesis in this sample. There was a significant correlation between overall CPQ score and Site-Specific Tooth Absences. Conclusion Children’s overall CPQ score and domain scores were significantly worse than their parents indicating that children with oligodontia had poorer OHRQoL compared to what was perceived by their parents.
