Objectives: This study aimed to investigate differences in unmet dental care needs according to employment status and if factors have relevance to unmet dental care needs due to “economic burden” and “no time to spare for visiting”. Methods: Multivariate logistic regression analysis was performed to examine the factors that affected the prevalence of unmet dental care needs due to “economic burden” and “no time to spare for visiting” in an economically active population comprised of subjects aged 20-64 years. Results: Compared to regular workers, part-time workers experienced 1.28-times more unmet dental care needs, while students experienced 0.64-times fewer unmet dental care needs. With regard to reasons related to “economic burden”, the rate of experiencing unmet dental care needs was 1.37-times higher for part-time workers than for regular workers. Regarding reasons related to “no time to spare for visiting”, the rate of experiencing unmet dental care needs was 0.51-times lower in part-time workers compared with regular workers. In economically inactive people, these values were 0.51-times lower in the unemployed, 0.37-times lower in students, 0.23-times lower in house workers, 0.20-times lower in subjects with disease and injury, and 0.20-times lower in early retirees compared to regular workers. Conclusions: Part-time workers experienced more unmet dental care needs compared with regular workers. With regard to “economic burden”, a significant difference in unmet dental care needs was observed between regular workers and part-time workers. Additionally, regarding “no time to spare for visiting”, people who were economically inactive because of unemployment, student or house-worker status, diseases and injury, and retirement experienced fewer unmet dental care needs compared with regular workers.
