OBJECTIVE: To evaluate the association between the pulp involvement, ulceration, fistula, abscess (PUFA) index and oral health-related quality of life (OHRQoL) of 5-year-old Brazilian children.
METHODS: This was a cross-sectional, population-based study using data from the oral health survey SB Brasil 2023. A total of 7,198 children examined by trained teams were included. The exposure variable was the presence of clinical consequences of untreated caries in primary teeth, assessed by PUFA. OHRQoL was assessed using the SOHO-5 instrument for 5-year-olds. The analysis considered a complex sampling design, using Poisson regression to estimate prevalence ratios (PR) and linear regression.
RESULTS: The prevalence of clinical consequences of untreated caries (PUFA≥1) was 41.1%, with a higher prevalence among Black, Brown, Asian, and Indigenous children compared to White children. Attending school (PR 0.69; 95%CI 0.53-0.90) and a family income above R$ 4,000.00 (PR 0.59; 95%CI 0.42-0.84) showed a protective effect. The North and Central-West regions had higher prevalence rates than the Southeast. and OHRQoL was worse among children of mixed race and indigenous descent compared to those of white skin color. Furthermore, children with dental caries had a 1.44-point higher OHRQoL score (β=1.44; 95%CI 1.01-1.86), which indicates a worse OHRQoL.
CONCLUSION: The clinical consequences of untreated dental caries have a negative impact on the OHRQoL of Brazilian children, influenced by social and racial determinants. These findings reinforce the need for public policies aimed at reducing regional inequalities and expanding oral health promotion and prevention actions.
