Psychosocial associated factors of early childhood caries and oral health-related quality of life: Structural equation model approach.

OBJECTIVE

To identify a structural model for the identification of psychosocial associated factors of early childhood caries (ECC) and oral health-related quality of life (OHRQoL) in preschool children and their families.

METHODS

A population-based cross-sectional study was conducted with 533 preschool children from 4 to 6 years-old public and private preschools, from Ribeirão das Neves, MG. Parents/caregivers self-completed the Brazilian versions of the Early Childhood Oral Health Impact Scale (B-ECOHIS) and Resilience Scale as well as a structured questionnaire addressing socioeconomic status and child's oral health behavior. Two dentists who had undergone training and calibration exercises for ICDAS‑epi and pufa index (Kappa≥0.95) performed the examinations for ECC. Stages of ECC were classified as free of visible carious lesion, initial caries, moderate caries, extensive caries without pulp consequences and extensive caries with pulp consequences. Data were analyzed using structural equation modeling, using Mplus version 8.6.

RESULTS

Lower socioeconomic status (b=-0.250; p<0.001) and higher frequency of free sugar consumption (b = 0.122; p = 0.033) were directly associated with a more severe stage of ECC. Lower parental resilience had an indirect impact on more severe stage of ECC which was mediated by the variable 'frequency of free sugar consumption' (b=-0.089; p = 0.048). ECC was associated with lower child's OHRQoL (b = 0.587; p<0.001) and lower family's OHRQoL (b = 0.506; p<0.001).

CONCLUSION

Structural modeling revealed that the severity of ECC negatively impacted the OHRQoL of preschoolers and their families. The main associated factors of the severity of ECC were lower socioeconomic status, higher frequency of free sugar consumption and lower parental resilience.

CLINICAL SIGNIFICANCE

T The findings indicate that psychosocial and behavior variables can be associated with the severity of ECC, and ECC can be associated with negative impact on wellbeing and ability to perform daily activities of preschoolers and their families.
