Caries progression as a risk factor for increase in the negative impact on OHRQOL—a longitudinal study

Abstract

Objectives

The aim of this study is to evaluate the association between caries lesions progression and oral health-related quality of life (OHRQoL) among Brazilian preschools, after 2 years.

Materials and methods

At baseline, 163 children (3–4 years old) enrolled in 12 public primary care services in Porto Alegre/RS-Brazil were evaluated. After 2 years, 119 children were re-evaluated. Calibrated examiners employing the ICDAS criteria conducted clinical examinations. A socio-demographic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale were applied to the parents of the children at baseline and 2-year follow-up. Data analysis was performed using a hierarchical approach based in a conceptual framework testing by Poisson regression.

Results

The number of surfaces that progressed from baseline to 2-year follow-up was associated with an increased negative impact on OHRQoL.

Conclusions

Caries progression increased the negative impact on OHRQoL.

Clinical relevance

The progression of caries lesions could negative impact on OHRQoL in Brazilian preschoolers.
