Malocclusion negatively impacted the oral health-related quality of life of children of low socioeconomic status

Abstract

Abstract
 Aim: This study assessed whether the presence of malocclusion had a negative impact on the oral health-related quality of life (OHRQoL) of eight to ten-year-old children of low socioeconomic status.
 Methods: A cross-sectional study was conducted with a total of 111 children, eight to ten years of age, randomly selected from public schools from Diamantina, MG, Brazil. The number of children was determined by a sample size calculation. Two calibrated examiners performed clinical oral examinations for the diagnosis of malocclusion, dental caries experience, and traumatic dental injuries following the Dental Aesthetic Index (DAI), the World Health Organization (WHO), and Andreasen’s classification, respectively. The Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) was applied to evaluate the OHRQoL. Descriptive and bivariate (p < 0.05) analyses were also performed.
 Results: Children had a mean age of 8.89 ± 0.82 years, of which 52.3% were female. The prevalence of malocclusion was 62.2%. Significant differences were found in emotional (p = 0.045) and social (p = 0.017) well-being subscale scores as well as in the total CPQ8-10 (p = 0.022) scores between children with and without malocclusion.
 Conclusion: The presence of malocclusion negatively impacted the OHRQoL of children aged eight to ten years of age of a low socioeconomic status.

Effect of self-perceived oral habits on orofacial dysfunction and oral health-related quality of life among a group of Egyptian children: a cohort study

“…All the above-mentioned conditions were potential confounders, thus were treated by restriction from the study sample (Berger et al 2009 ; Hashem et al 2013 ; Montes et al 2019 ; Sharna et al 2019 ; Coutinho et al 2020 ).…”

“…Any condition that affects the well-being of the orofacial complex will have an impact on OHRQoL. Hypodontia, amelogenesis imperfecta, early childhood caries (ECC), molar incisor hypomineralisation (MIH), cleft lip and palate, malocclusion, dental trauma, and any other oral/dental conditions are found to have its impact on OHRQoL (Berger et al 2009 ; Hashem et al 2013 ; Kappen et al 2019 ; Montes et al 2019 ; Sharna et al 2019 ; Coutinho et al 2020 ). Child’s OHRQoL measures are targeting the assessment of orofacial structures’ well-being and function, and their effect on the child’s emotional and social perception, from the child’s or his parents’ point of view (Thomson et al 2013 ).…”
