Abstract

Objectives: The objectives of this study were to evaluate the effect of smoking on utilization of and expenses in ambulatory dental care. Methods: The subjects of this study were 5,751 men aged over 20 years selected from the Korea Health Panel data collected during 2010-2012. Pack-years of smoking were calculated based on the survey data. Dental utilization was defined as dental outpatient clinic use least once in three years. The expenses in ambulatory dental care were summed to determine total dental health care spending for three years. To detect the effect of smoking, we used multiple logistic regression analysis for dental utilization and multiple linear regression for expenses in ambulatory dental care after changing log. Results: The pack-years had a significant effect on dental utilization and expenses in participants aged 40-59 years. After controlling for income level, bedtime brushing, and the presence of chronic disease, dental care utilization rates in the over 10 to less than 25 pack-year and the over 25 pack-year groups were about 1.4 (OR=1.37, (P =0.007)) and 1.6 times (OR=1.59, (P =0.001)) those in the 0 pack-year group. In comparison with the 0 pack-year group, the over 10 to less than 25 pack-year group spent 50,000 won more over dental expenses, while the corresponding number for the over 25 pack-year group was about 100,000 won. Thus, the ambulatory dental care expenses increased with the packyears of smoking. Conclusions: Smoking significantly influenced the utilization and expense in ambulatory dental care in men aged 40-59 years.
