Abstract: Objective: The aims of this study were (1) to investigate willingness to pay (WTP) for preventive and curative dental care procedures and (2) to determine the factors that influence older adults’ WTP for dental care. Methodology: Older, independently living adults from Singapore aged 60 years and older and eligible for government-subsidised dental care were nonrandomly recruited for this study. Data were collected using questionnaires and a clinical examination which recorded details of caries experience, number and distribution of posterior occluding contacts, prosthodontic status, and periodontal status. Using a contingent valuation method, participants were asked to rate WTP in Singapore dollars [SGD$] for 4 aspects of care: dental fillings, dental scaling, dental extraction, and disease prevention advice. Negative binomial regression was used to assess the relationship between the predictor variables associated with WTP for dental fillings, scaling, extraction, and preventive advice. Results: The mean value of WTP for a dental filling was SGD$30.23 (SGD$31.05), for scaling was SGD$30.28 (SGD$29.46), for dental extraction was SGD$35.08 (SGD$58.54). In a multivariate model, factors associated with higher WTPfees were as follows: (1) dental filling: age (younger), level of education (higher), and frequency of dental visits (regular); (2) scaling: level of education (higher), agree that dental problems affect overall health, and frequency of dental visits (regular); (3) dental extractions: age (younger), level of education (higher), frequency of dental visits (regular), and prosthodontic status (not wearing); (4) preventive advice: age (younger), gender (male), ethnicity (Chinese), level of education (higher), marital status (married), self-perceived oral health (good), and dental visits (regular). Conclusions: The findings of our study suggest that older adults are willing to pay most for extraction and least for preventive advice.
