Many countries provide preventive dental care for children to reduce inequalities. In Korea, the registered dentists’ program was implemented to promote oral health and prevent oral diseases in primary school students. This study aimed to evaluate the registered dentist program through the sealant utilization rate using national cohort data and to compare the socioeconomic gap of the cohorts by participation. The sample cohort data were obtained from the National Health Insurance Sharing Service (NHISS) in South Korea. The utilization of dental sealants was analyzed using the chi-square test according to the independent variables of each year. To identify the independent effects of participation in the registered dentists’ program, a panel logistic regression analysis of the utilization of dental sealants was performed. The participants were 1.35 times more likely to have dental sealants than non-participants. The significance of income quintiles disappeared in the case groups. The gap became more obvious in the employees of the control group even after adjusting for all variables. Implementing oral health programs can alleviate inequality with a relative increase in utilization in vulnerable populations.

注册牙医计划是否可以减轻使用牙科密封剂的社会经济差距？

许多国家为儿童提供预防性牙科护理，以减少不平等现象。在韩国，实施了注册牙医计划，以促进小学生的口腔健康和预防口腔疾病。这项研究旨在通过使用国家队列数据通过密封剂利用率评估注册牙医计划，并通过参与比较队列的社会经济差距。样本群组数据来自韩国国家健康保险共享服务（NHISS）。根据每年的独立变量，使用卡方检验分析了牙科密封胶的利用率。为了确定参与注册牙医计划的独立影响，对牙科用密封胶的利用进行了小组逻辑回归分析。参加者是1。具有牙科密封剂的可能性是非参与者的35倍。收入五分位数的重要性在病例组中消失了。即使在调整所有变量之后，对照组的员工之间的差距也更加明显。实施口腔保健计划可以缓解不平等现象，同时使脆弱人群的利用相对增加。
