Exploring the association between oral health problems and oral health-related quality of life in Peruvian 11- to 14-year-old children

Abstract

Background: This is the first study that tested a Spanish version of the Child Perceptions Questionnaire (CPQ<inf>11-14</inf>) in a population-based sample. Aim: To assess the impact of oral health problems on OHRQoL in 11- to 14-year-old children. Design: Data from 473 11- to 14-year-old children were analysed. They were interviewed using the CPQ11-14. Examinations included dental caries, malocclusion, and traumatic dental injuries. Adjusted Poisson regression was used to associate different clinical conditions to the outcome. Results: Overall, 100% of children reported oral impacts (total CPQ<inf>11-14</inf> score ≥ 1). Children aged 12- to 14 years old experienced a negative impact on all domains and total CPQ11-14 scores (P < 0.05); the increase in DMFT index showed a negative impact on the oral symptoms domain (RR = 1.01; P = 0.05, whereas Class III malocclusion showed a positive impact on the emotional well-being domain (RR = 0.71; P < 0.01). TDI (RR = 1.11; P = 0.01) and crown discoloration (RR = 1.23; P < 0.01) showed a negative impact on the emotional social well-being domain. Conclusion: Children aged 12- to 14 years old had a negative impact on all domains and total CPQ11-14 scores compared with those who are 11 years old. The increase in dental caries experience, presences of TDI and crown discoloration have a negative impact on some aspects of the children's OHRQoL. Class III malocclusion showed a positive impact on the emotional well-being domain. © 2016 Elsevier B.V., All rights reserved.
