Schoolchildren with malocclusion from lower-income families experience a greater negative impact on OHRQoL.
ObjectiveThe aim of the present study was to translate, perform the cross-cultural adaptation of the Rapid Estimate of Adult Literacy in Dentistry to Brazilian-Portuguese language and test the reliability and validity of this version.MethodsAfter translation and cross-cultural adaptation, interviews were conducted with 258 parents/caregivers of children in treatment at the pediatric dentistry clinics and health units in Curitiba, Brazil. To test the instrument's validity, the scores of Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) were compared based on occupation, monthly household income, educational attainment, general literacy, use of dental services and three dental outcomes.ResultsThe BREALD-30 demonstrated good internal reliability. Cronbach’s alpha ranged from 0.88 to 0.89 when words were deleted individually. The analysis of test-retest reliability revealed excellent reproducibility (intraclass correlation coefficient = 0.983 and Kappa coefficient ranging from moderate to nearly perfect). In the bivariate analysis, BREALD-30 scores were significantly correlated with the level of general literacy (rs = 0.593) and income (rs = 0.327) and significantly associated with occupation, educational attainment, use of dental services, self-rated oral health and the respondent’s perception regarding his/her child's oral health. However, only the association between the BREALD-30 score and the respondent’s perception regarding his/her child's oral health remained significant in the multivariate analysis.ConclusionThe BREALD-30 demonstrated satisfactory psychometric properties and is therefore applicable to adults in Brazil.
Oral health-related quality of life (OHRQoL) is an important aspect of health outcomes and its assessment should be made using validated instruments. The psychosocial impact of dental aesthetics questionnaire (PIDAQ) is an OHRQoL instrument that assesses the psychosocial impact of dental aesthetics was developed and validated for use on young adults. The aim of the present study was to assess the reliability, validity, and applicability of the PIDAQ for young adults in Brazil. After translation and cross-cultural adaptation, the questionnaire was completed by 245 individuals (124 males and 121 females) aged 18-30 years from the city of Belo Horizonte, Brazil. In order to test discriminant validity, the subjects were examined for the presence or absence of malocclusion based on the dental aesthetic index criteria. Dental examinations were carried out by a previously calibrated examiner [weighted kappa = 0.64-1.00, intraclass correlation coefficient (ICC) = 0.78-1.00]. Internal consistency measured by Cronbach's alpha of the subscales was between 0.75 and 0.91 and test-retest reliability was assessed using the ICC, which ranged from 0.89 to 0.99 for dental self-confidence and social impact, thereby revealing satisfactory reliability. Discriminant validity revealed that subjects without malocclusion had different PIDAQ scores when compared with those with malocclusion. The results suggest that the Brazilian version of the PIDAQ has satisfactory psychometric properties and is thus applicable to young adults in Brazil. Further research is needed to assess these properties in population studies.
BackgroundTraumatic dental injury (TDI) during childhood may negatively impact the quality of life of children.ObjectiveTo describe the association of oral health-related quality of life (OHRQoL) and domains (oral symptons, functional limitation, emotional- and social-well-being) of children with individual and contextual variables.MethodsA cross-sectional study was performed using a representative sample of 1,201 schoolchildren, 8–10 years-old, from public and private schools of Belo Horizonte, Brazil. The CPQ8–10 was used to assess OHRQoL, dichotomized in low and high impact. Sociodemographic information was collected through questionnaires to parents. Children were examined at schools, using the Andreasen criteria. Individual variables were gender, age, number of residents in home, parents/caregivers’ level of education, family income, and TDI (dichotomized into without trauma/mild trauma and severe trauma). Dental caries and malocclusion were considered co-variables. Contextual variables were the Social Vulnerability Index and type of school. Ethical approval and consent forms were obtained. Data were analyzed using SPSS for Windows 19.0 and HLM 6.06, including frequency distribution, chi-squared test and multilevel approach (p < 0.05).ResultsThe prevalence of a negative impact on OHRQoL in children with severe trauma was 55.9%. The TDI negatively impacted emotional and social domains of OHRQoL. A multilevel analysis revealed a significant difference in OHRQoL according to the type of school and showed that 16% of the total variance was due to contextual characteristics (p < 0.001; ICC = 0.16). The negative impact on OHRQoL was higher in girls (p = 0.009), younger children (p = 0.023), with severe TDI (p = 0.014), those from public schools (p = 0.017) and whose parents had a lower education level (p = 0.001).ConclusionSevere trauma impacts OHRQoL on emotional and social domains. Contextual dimensions add information to individual variability to explain higher impact, emphasizing socioeconomic inequalities.
PurposeThe objective of this study was to assess the negative impact of dental caries on the OHRQoL of 8- to 10-year-old Brazilian children.MethodsThis population-based case-control study involved 546 children (8–10 years old), 182 cases with a high negative impact on OHRQoL and 364 controls with a low negative impact on OHRQoL. Children’s OHRQOL was measured using the Child Perceptions Questionnaire (CPQ8-10). Cases and controls (1x2 ratio) were individually matched by school and gender. Dental caries experience, malocclusion, and traumatic dental injuries were used as independent variables. Dental examinations were carried out at school during daytime hours by two calibrated examiners (Kappa = 0.93-interexaminer and 0.95- intraexaminer). The data were analyzed by descriptive statistics, conditional bivariate and multiple logistic regression, with the significance level set at 5%.ResultsThere was no significant difference in traumatic dental injuries and malocclusion between the case and control groups (p>0.05). Children with DMFT/dmft ≥3 had a 2.06-fold (95%CI = 1.28–3.31, p = 0.003) greater chance of experiencing a high negative impact on OHRQoL than those with DMFT/dmft = 0ConclusionChildren with high dental caries experience are more likely to present a high negative impact on OHRQoL than those with no dental caries experience.
