Condition-specific sociodental impacts attributed to different anterior occlusal traits in Brazilian adolescents.
ABSTRACT The aim of this study was to assess the association between different anterior occlusal traits and the presence of condition-specific sociodental impacts on the quality of life attributed to malocclusion. For that, 1,318 15-16-yr-old adolescents were randomly selected from children attending all secondary schools in Bauru, Brazil. Participants were first interviewed and then dentally examined. Condition-specific impacts (CSI) attributed to malocclusion were calculated using the Oral Impacts on Daily Performances (OIDP index). Nine anterior occlusal traits were evaluated: maxillary and mandibular overjet; openbite and overbite; centreline deviation; dental crowding and spacing; and maxillary and mandibular irregularity. Statistical associations were tested using binary logistic regression analysis. The prevalence of CSI attributed to malocclusions was 21.2%. Of the nine occlusal traits evaluated, maxillary and mandibular overjet, centreline deviation, dental spacing, openbite, and maxillary irregularity were, in that order, directly associated with the presence of CSI attributed to malocclusion. No interaction term was identified. This study, designed to overcome the limitations found in the existing literature, supports the idea that malocclusion can affect social interaction and psychosocial wellbeing. Different anterior occlusal traits affected the quality of life differently.
Article: Impact of socioeconomic and clinical factors on child oral health-related quality of life (COHRQoL).[show abstract] [hide abstract]
ABSTRACT: Child oral health-related quality of life (COHRQoL) has been increasingly assessed; however, few studies appraised the influence of socioeconomic status on COHRQoL in developing countries. This study assessed the relationship of COHRQoL with socioeconomic backgrounds and clinical factors. This study followed a cross-sectional design, with a multistage random sample of 792 schoolchildren aged 12 years, representative of Santa Maria, a southern city in Brazil. Participants completed the Brazilian version of the Child Perceptions Questionnaire (CPQ(11-14)), their parents or guardians answered questions on socioeconomic status, and a dental examination provided information on the prevalence of caries, dental trauma and occlusion. The assessment of association used hierarchically adjusted Poisson regression models. Higher impacts on COHRQoL were observed for children presenting with untreated dental caries (RR 1.20; 95% CI 1.07-1.35) and maxillary overjet (RR 1.19; 95% CI 1.02-1.40). Socioeconomic factors also associated with COHRQoL; poorer scores were reported by children whose mothers have not completed primary education (RR 1.30; 95% CI 1.17-1.44) and those with lower household income (RR 1.13; 95% CI 1.02-1.26). Poor socioeconomic standings and poor dental status have a negative impact on COHRQoL; reducing health inequalities may demand dental programmes and policies targeting deprived population.Quality of Life Research 11/2010; 19(9):1359-66. · 2.30 Impact Factor
