Abstract

Objective

This study aims to evaluate the impact of untreated dental caries and its clinical consequences on the quality of life of Brazilian schoolchildren aged 8–10 years.

Methods

A randomly selected sample of 587 children underwent a clinical oral examination for the assessment of untreated dental caries and clinical consequences. The WHO criteria (decayed component of the decayed, missing, and filled teeth—D-DMFT in permanent teeth or d-dfmt in primary teeth) and the PUFA index, which records the presence of severely decayed permanent (upper case) and primary (lower case) teeth with visible pulpal involvement (P/p), as well as ulceration caused by dislocated tooth fragments (U/u), fistula (F/f), and abscesses (A/a), were used for the oral examination. Oral health-related quality of life (OHRQoL) was evaluated using the Child’s Perception Questionnaire (CPQ8–10). Poisson regression was employed to test unadjusted and adjusted associations between untreated dental caries/clinical consequences and OHRQoL.

Results

The prevalence of untreated dental caries was 64.6 % (D/d component of DMFT/dmft > 0) and 17.9 % of children exhibited clinical consequences of caries (PUFA/pufa index >0). In the adjusted models, untreated caries was significantly associated with the total CPQ8–10 score and all subscale scores. The clinical consequences of dental caries (PUFA/pufa index >0) were significantly associated with the total CPQ8–10 as well as the oral symptoms and functional limitations’ subscales.

Conclusion

Untreated dental caries and its clinical consequences exerted a negative impact on the OHRQoL of the schoolchildren analyzed.
