The impact of malocclusion on the quality of life among children and adolescents: a systematic review of quantitative studies

Abstract

The scientific evidence was considered strong since four studies with high level of quality reported that malocclusions have negative effects on OHRQOL, predominantly in the dimensions of emotional and social wellbeing.

Impact of a dental care program on the quality of life of children with and without caries

“…21 Originally drafted in Canada, the CPQ [8][9][10] has been translated and validated for use in other countries, including Brazil. 22 The questionnaire was self-administered in the school environment and it was used to evaluate the OHRQoL of the two groups.…”

“…22 The questionnaire was self-administered in the school environment and it was used to evaluate the OHRQoL of the two groups. 23 The CPQ [8][9][10] consists of 25 questions organized into four health domains: oral symptoms (OS) (n = 5), functional limitations (FL) (n = 5), emotional well-being (EWB) (n = 5), and social well-being (SWB) (n = 10). Each item is scored on a 5-point Likert scale to rate the impact of oral health status on a given aspect of quality of life (described by the item).…”

“…In addition to the 25 items of the CPQ [8][9][10] , global questions were assessed at baseline and follow-up to evaluate changes in OHRQoL. At baseline, the CPQ [8][9][10] asks global questions about subjective aspects of oral health (very good, good, fair, and poor).…”

“…atraumatic restorative treatment, traumatic dental injury, and other treatments, 10,11,12,13,14,15,16,17,18 few have evaluated the longitudinal impact of dental caries treatment on children's OHRQoL by considering subjective aspects. 14,15,16,17,18 Most studies comparing OHRQoL scores between children with and without dental caries have a cross-sectional design, which refrains them from determining the causal relationship between an intervention and an outcome.…”

“…A one-year follow-up was conducted with a sample of 372 children aged 8 to 10 years which were clinically examined and divided into two matched groups according to their caries experience: dental treatment group (DTG) and group without caries (GWC). Both groups were assessed three times (at baseline, at 4 weeks, and at 1 year) using the Child Perceptions Questionnaire (CPQ [8][9][10] ). The normality test was performed for the statistical analyses; the Friedman test was used for the dependent variables (longitudinal assessment repeated three times for the same group); and the Mann-Whitney test was used for the independent variables (test and control groups in each time period).…”
