Does subsidizing the cost of care impact on dental attendance patterns among older adults?

OBJECTIVES: To assess whether eligibility for an age-related universal (pioneer generation [PG]) subsidy incentivises dental attendance by older Singaporeans. METHODS: Data were collected between 2018 and 2021 from in-person interviews of Singaporean adults aged 60-90 years using a questionnaire and a clinical examination. The questionnaire included details of age, gender, ethnicity, education, residential status, socio-economic status, marital status, eligibility for subsidy (community health assistance/CHAS, PG or both) and frequency of dental attendance. The clinical examination recorded number of teeth (categorized as edentulous, 1-9 teeth;10-19 teeth; ≥20 teeth). To estimate the effect of the PG subsidy on dental attendance pattern, a regression discontinuity (RD) analysis was applied using age as the assignment variable. RESULTS: A total of 1172 participants aged 60-90 years (64.2% female) were recruited, with 498 (43%) being eligible for the PG subsidy. For those eligible for PG subsidy, there was a higher proportion of regular attenders than irregular attenders (53.6% vs. 46.4%). In age adjusted RD analysis, those eligible for the PG subsidy were 1.6 (95% CI: 1.0, 2.7) times more likely to report regular attendance than their PG non-eligible counterparts. The association remained strong (OR 2.1; 95% CI: 1.1-3.7) even after further controlling for demographics, socioeconomic factors, number of teeth and eligibility for the CHAS subsidy. CONCLUSIONS: Being eligible for the PG subsidy substantially increased the odds of regular dental attendance.

The relationship between self-efficacy and oral health status of older adults.

OBJECTIVES: The objectives of this study were to determine the relationship between reported self-efficacy and dental status in older adults, identify factors which might influence self-efficacy and, their willingness to pay (WTP) for preventive care. METHODS: Participants aged 60-90 years of age living in Singapore were recruited. All participants completed an oral health questionnaire and a clinical examination. Details of participants' socio-economic status and educational attainment were collected, and participants also answered a range of questions related to self-efficacy, oral health attitudes, beliefs and dental attendance patterns. Participants were asked to indicate their willingness to pay for preventive care using contingent valuation. The clinical examination recorded decayed, missing and filled teeth [DMFT], root caries, periodontal attachment loss, bleeding on probing index, occlusal status and, denture wearing status. Associations between self-efficacy, self-report and clinical variables were assessed using Kendall's Tau B coefficient. RESULTS: 614 participants [mean age 68.07 (5.99) years] were recruited. There was a high level of dental awareness and nearly 70% of the participants reported visiting a dentist once or twice a year. Self-efficacy was associated with levels of bleeding on probing and self-reported satisfaction with oral health. Nearly 60% of participants were not willing to pay for preventive advice from an oral healthcare professional. CONCLUSION: Older adults with a high level of self-efficacy had good gingival health, with low reported levels of bleeding on probing. Participants with low reported self-efficacy had higher disease levels and were less satisfied with their oral health. CLINICAL SIGNIFICANCE: Self-efficacy in relation to oral hygiene practices is variable, and participants with low self-efficacy had higher gingival bleeding scores. However, willingness to pay for preventive advice is low, and further work is required to increase the value proposition of preventive care to older adults.
