Abstract

Purpose

Evaluate the impact of the premature loss of primary molars due to caries on oral health-related quality of life (OHRQoL) in schoolchildren.

Methods

A cross-sectional study was conducted with children eight to ten years of age at public schools in the city of Florianópolis selected through cluster sampling. The collection of the clinical data occurred in the school setting by four trained and calibrated examiners (Kappa > 0.7) DMFT/dmft index, PUFA/pufa index, accentuated overjet, and anterior open bite. Sex and age of the child and guardian’s schooling (classified as ≤ 8 or > 8 years) were collected through a questionnaire answered by the guardians. OHRQoL was assessed using the Child Perceptions Questionnaire 8–10. The data were submitted to bivariate, multivariate, and hierarchical Poisson analyses.

Results

A total of 1456 children participated in the study. The prevalence of premature tooth loss due to caries was 5.8% (n = 85). The prevalence of negative impact on OHRQoL was 47.4% (n = 691). Negative impact on OHRQoL was significantly associated with the premature loss of primary molars (p < 0.001) as well as the sex (girls), guardian’s schooling (> 8 years) and the presence of untreated caries (p < 0.001).

Conclusion

The premature loss of primary molars due to caries was associated a negative impact on the OHRQoL of children eight to ten years of age. Negative impact is also associated with untreated caries, sex, and the level of schooling of guardians.
