Perceived impact of dental pain on the quality of life of children aged 1-3 years and their families.

PURPOSE

To evaluate the perceived impact of dental pain on oral health-related quality of life (OHRQoL) among children aged 1-3 years and their families.

METHODS

A cross-sectional study was conducted with 306 randomly selected preschool and day care children in the city of Diamantina, Brazil. Parents/caregivers answered a questionnaire on socio-demographic information, the Brazilian version of the Early Childhood Oral Health Impact Scale, their child's general/oral health and the Brazilian version of the Dental Discomfort Questionnaire. The children underwent an oral examination. Descriptive statistics, Spearman's correlations, the Kruskal-Wallis test, Mann-Whitney test and Poisson regression were used to determine associations between the variables (prevalence ratio [PR], α = 5%).

RESULTS

The prevalence of dental caries and dental pain was 43.1% and 40.2%, respectively. Dental pain (PR: 1.96, 95% CI 1.52-2.54; p < 0.001), monthly household income (PR: 1.38, 95% CI 1.04-1.83; p = 0.026) and dental caries (PR: 1.06, 95% CI 1.03-1.10; p < 0.001) were significantly associated with the perceived impact on OHRQoL.

CONCLUSIONS

Dental pain, household income and dental caries were associated with a negative impact on the OHRQoL of children aged 1-3 years and their families.
