The author analyzes an insurance database to evaluate the utilization of dental care preventive service and cost-benefit effectiveness of teeth fluoridation and anti-decay treatment program in central part of Taiwan.

全民健康保险自93年7月1日起实施儿童牙齿涂氟预防保健服务迄今已逾四年，本研究旨在探讨使用该项预防保健服务对健保牙医医疗利用之影响，并对涂氟支出之成本与减少之医疗费用进行成本效益分析（cost-benefit analysis，CBA）。

Methods: A retrospective study was conducted using an insurance database from Bureau of Nation Health Insurance - Central regional branch with registered children born in 2001 who received teeth fluoridation and anti-decay program. The difference of utilization of dental care preventive service analysis was based on each individual child's character and required dental treatment. For cost-benefit analysis, children were selected who were eligible receiving or non- receiving this benefit from July 1, 2004 till 2007. Two groups were compared by frequency matching analysis, based on sex, medical provide territories, insured fee. Additional Incremental benefit/cost method of cost-benefit analysis is also conducted to evaluate the service providing cost increasing and dental treatment cost decreasing effectiveness.

研究方法主要系透过健保局中区分局93年至96年儿童牙科医疗费用统计资料，比较90年次出生之儿童接受涂氟预防保健服务之人口学特质及其涂氟前后牙科医疗利用差异；并依该等对象接受涂氟预防保健服务与否区分两组，就其性别、就医地区别与全民健保投保金额组别等予以配对，进一步应用成本效益分析（cost-benefit analysis，CBA）之增量益本比（Incremental benefit/cost method，IBC），探讨儿童牙齿涂氟预防保健服务成本的增加，使牙科医疗费用减少所带来效益的增加为何。
