Abstract
Objective: Interventions for better denture cleansing would be more successful if they can improve oral health-related quality of life (OHQoL), thus reinforcing patient’s compliance. Nevertheless, it is currently unknown whether precarious denture hygiene is associated with poor OHQoL. This study aimed to assess the association between denture biofilm coverage and OHQoL in a sample of adult edentulous patients wearing complete dentures. Material and method: The sample was composed by 80 participants (20 men and 60 women, mean age of 65.0 ± 9.1 years) who requested new complete dentures in a university clinic. The variable used as a measure of denture hygiene was biofilm coverage area, which was quantified by means of a computerized method. Afterwards, participants answered the OHIP-EDENT instrument and questions about socio-demographic parameters. Bivariate tests and multiple regression quantified the association between denture biofilm and other variables (α=0.05). Result: Correlation between biofilm coverage area and OHQoL, as well as with most socio-demographic variables, was weak and non significant. Multiple regression confirmed the lack of association between denture biofilm and OHQoL. Conclusion: It can be concluded that denture hygiene is independent of OHQoL for the average complete denture wearers.

Resumo
Objetivo: Intervenções visando à melhor higiene de próteses totais podem ter maior chance de sucesso caso levem à melhora da qualidade de vida relacionada à saúde bucal (QVSB), assim melhorando a colaboração do paciente. No entanto, não se conhece se há associação entre a higiene precária das próteses e pobre QVSB. Assim, este estudo buscou avaliar a associação entre a área coberta por biofilme sobre próteses totais e a QVSB em uma amostra de pacientes completamente desdentados. Material e método: Uma amostra foi composta por 80 participantes (20 homens e 60 mulheres, média etária de 65,0 ± 9,1 anos) que solicitavam novas próteses totais em uma clínica universitária. A variável usada como medida para a higiene das próteses foi a área coberta por biofilme, quantificada por meio de um método computadorizado. Em seguida, participantes responderam ao instrumento OHIP-EDENT e a questões sobre parâmetros sócio-demográficos. Testes bivariados e regressão múltipla quantificaram a associação entre o biofilme e as demais variáveis (α=0,05). Resultado: A correlação da área coberta por biofilme com a QVSB, bem como com a maioria das variáveis sócio-demográficas, foi fraca e não significante. A regressão múltipla confirmou essa falta de associação entre o biofilme das próteses e a QVSB. Conclusão: É possível concluir que a higiene de próteses totais é independente da QVSB para o usuário de próteses totais regular.
