Oral Health-Related Quality Of Life of Pre-School Children: Review and Perspectives for New Instruments

Traumatic dental injuries and molar incisor hypomineralization: a cross-sectional study of schoolchildren from southern Brazil

PURPOSE

To describe the prevalence and the variables associated with TDIs in schoolchildren aged 8 to 14 years in Estância Velha city in southern Brazil, placing emphasis on molar incisor hypomineralization.

METHODS

Students enrolled in public schools of a medium-sized city in the southern Brazil were selected using cluster random sampling. Clinical examinations assessed molar incisor hypomineralization-MIH (European Academy of Pediatric Dentistry criteria), dental caries (DMFT index), and TDIs (O'Brien's criteria). Socioeconomic and demographic variables were assessed using a standardized questionnaire. Prevalence ratios were estimated using Poisson regression (p < 0.05).

RESULTS

513 students (54.8% female), with a mean age of 11.6 (± 1.9) years, participated in the study. The prevalence of TDIs was 11.3%, with enamel fracture representing 90.4%. The high prevalence of traumatic dental injuries was associated with MIH (PR: 2.22 CI: 1.27; 3.87; p < 0.01) and overjet > 3 mm (PR: 2.03 CI 1.19; 3.45; p < 0.01).

CONCLUSION

The sample of schoolchildren from southern Brazil had a low prevalence of traumatic dental injuries. Molar incisor hypomineralization and increased overjet were associated with the higher prevalence of traumatic dental injuries.

Family functioning and preschool children's oral health-related quality of life

INTRODUCTION

Identifying which aspects of how a family functions are relevant to child oral health provides opportunities for interventions targeting the family context. The aim of this study was to investigate the associations of general and domain-specific family functioning with oral health-related quality of life (OHRQoL) of 3-4-year-old children.

METHODS

Cross-sectional data from 740 parent-child dyads from East London were analysed. Family functioning was assessed with the 60-item Family Assessment Device that yields scores for general functioning and six domains (roles, behaviour control, communication, affective involvement, affective responsiveness and problem solving). Children's OHRQoL was measured using the Early Childhood Oral Health Impact Scale (ECOHIS), which measures the lifetime impacts of children's oral conditions on the child (child impact section, CIS) and family (family impact section, FIS). The associations of family functioning with the ECOHIS total, CIS and FIS scores were assessed in negative binomial regression models (rate ratios [RR] and 95% confidence intervals [95% CI] were calculated), adjusting for parental sociodemographic factors and child demographic factors and caries experience.

RESULTS

Children in families with unhealthy general functioning had 1.45 (95% CI: 0.87-2.43), 1.24 (95% CI: 0.73-2.13) and 2.19 (95% CI: 1.20-3.99) times greater ECOHIS total, CIS and FIS scores, respectively, than those in families with healthy general functioning after adjustment for confounders. Unhealthy functioning in the roles domain was associated with greater ECOHIS total and FIS scores. Unhealthy functioning in the problem solving, roles and affective involvement domains were also associated with greater FIS scores.

CONCLUSIONS

Unhealthy family functioning was associated with worse child OHRQoL, especially in terms of disrupting family life. Effective assignment and undertaking of roles should be further explored as a target for intervention.
