Patterns of use of oral health care services in Australian rural adults : the Crossroads-II Dental sub-study

Background: As part of a larger study, the Crossroads-II Dental sub-study determined the patterns of, and barriers to, oral health care service utilization in a rural area of Victoria. Methods: In this cross-sectional sub-study predisposing, enabling, needs-related, and oral health variables were considered in association with patterns of oral health care utilization. A logistic regression was performed to explain the use of oral health care services. Results: Overall, 574 adults participated, with 50.9% reporting having visited an oral health care service in the previous 12 months. Age, number of chronic health conditions and holding a health card; were associated with increased visit to a dentist (OR = 1.01; 95% CI: 1.00-1.03; OR = 1.08; 95% CI: 1.01-1.16; OR = 2.06; 95% CI: 1.26-3.36, respectively). Perceived barriers to care and number of missing teeth decreased the odds of using services (OR = 0.46; 95% CI: 0.36-0.58; OR = 0.95; 95% CI: 0.92-0.98, respectively). Conclusions: Results suggest that use of oral health care services is associated with a range of financial, educational, health and structural barriers. Increasing the use of oral health care services in rural populations requires additional efforts beyond the reduction of financial barriers.
