Self-perception of need to replace dentures and oral health-related quality of life: cross-sectional study nested in a Cohort in Southern Brazil. Braz. J. Oral Sci.

Aim: With the significant increase in life expectancy over the last decades, it is important to understand how oral health can impact the oral health-related quality of life of older adults. This study aimed to investigate the association between need to replace dentures and oral health-related quality of life (OHRQoL) among older adults belonging to a Cohort in southern Brazil. Methods: This cross-sectional study was conducted with data from the 2019 Pelotas Elderly Cohort. The OHRQoL was assessed using the GOHAI. Need to replace dentures was self-report using a question dichotomized into yes/no. In the statistical analysis, unadjusted and adjusted models estimate from linear regression models were calculated. The significance level adopted was 5%. Results: A total of 493 older adults were included. On the GOHAI questionnaire, the mean score was 32.74 (SD±0.16). Individuals considering need of prosthesis replacement were 47.89%. Report of need to replace dentures was associated to lowest mean on the GOHAI score (β -1.14; 95%CI - 1.80; -0.478, and on the physical (β -0.56; 95%CI - 0.94 -0.17) and psychosocial (β -0.48; 95%CI - 0.74; -0.22) dimensions. Conclusion: Our findings highlight the importance of also considering subjective measures of oral health in the dental care of older adults, since reporting the need for denture replacement, regardless of the reason, was associated with a worse oral health-related quality of life, including physical and psychosocial aspects.
