Influence of malocclusion on oral health-related quality of life in children: a seven-year cohort study

Abstract

Objective: To assess the influence of early childhood malocclusion on oral health-related quality of life (OHRQoL). Methods: 7-year cohort study involving 639 preschoolers (1 to 5 years) who had been evaluated initially with a survey conduced in 2010. Children completed the Brazilian version of the Child Perception Questionnaire (CPQ8-10) to assess OHRQoL during the follow-up period. Exploratory variables were collected at baseline, including the presence and severity of malocclusion (overjet and lip coverage). Socioeconomic characteristics, oral health behavior, and patterns of dental attendance were also investigated. A multilevel Poisson regression model was used to fit the association between malocclusion and OHRQoL. With this approach, incidence rate ratio (IRR) and 95% confidence intervals (95% CI) were calculated. Results: A total of 449 children were re-evaluated (follow-up rate, 70.3%). The prevalence of accentuated overjet and inadequate lip coverage was 13.5% and 11.9%, respectively. The mean (±SD) CPQ8-10 score was 10.57±10.32. The presence of inadequate lip coverage was associated with higher overall mean CPQ8-10 scores (IRR 1.51; 95% CI 1.29-1.77), and social well-being, emotional well-being, and functional limitation domains. Children with accentuated overjet (>3mm) also demonstrated higher overall scores on the CPQ8-10 than their normal counterparts. The presence of this condition also influenced the oral symptom (IRR 1.29; 95% CI 1.08-1.53) and emotional well-being (IRR 1.30; 95% CI 1.02-1.66) domains. Conclusion: Results of the present study suggest that early childhood malocclusion is a risk factor for low OHRQoL in future.

Predictors associated with malocclusion in children with and without sleep disorders: a cross-sectional study

“…The early analysis of predictors of malocclusion is important, as malocclusion in the mixed dentition phase tends to persist in the permanent dentition 30 and can have a negative impact on quality of life. 3,9,10 The prevalence of malocclusion in this study was high (49.1%). This high prevalence was probably influenced by genetic factors, which were not assessed in our study.…”

“…[6][7][8] Malocclusion can cause functional and esthetic problems as well as psychosocial effects on self-esteem and social interacitons. 3,9 Besides being a risk factor for low quality of life in children, 10 malocclusion can also have a negative effect on the quality of life of families, with an impact on emotional aspects and family conflicts. 11,12 It is therefore important to investigate possible associations between biopsychosocial factors and malocclusion.…”

“…These individuals, who at that time were aged between 8 and 12 years, were again invited to participate in the evaluations. Other details and the results of the second phase of the study have already been published [ 35 , 36 ].…”

Malocclusion and Quality of Life in Children Aged 3 to 5 Years in Salvador-BA

“…Malocclusion consists of a change in the pattern of growth and development that directly affects the relationship between the teeth [1]. Its consequences involve the imbalance of the stomatognathic system and the impact on the quality of life of both children and adolescents [2][3][4].…”
