The national health screening (NHS) program in Korea serves as primary prevention by detecting oral diseases early for easier management. Dental scaling helps prevent oral disease and treat early periodontal disease. This study evaluated the effects of national oral examinations (NOE) in NHS on preventive oral hygiene care and dental treatments for a 19-year follow-up study.
We conducted a longitudinal observation of Korean adults ≥ 19 years between 2002 and 2003 from the Korean National Health Insurance Service (n = 4,669,107; men = 2,518,704; women = 2,150,403). The independent variable involved tracking the number of people who underwent the NOE recruited between 2002 and 2003 from 2002 to 2013. The dependent variables pertained to the number of dental scaling and the presence or absence of periodontal and dental caries treatments from 2014 to 2020.
Individuals receiving 6 to 7 dental scaling during the follow-up exhibited an adjusted odds ratio (AOR) of 2.91 in the NOE-middle (3-4 times) and 3.30 in the NOE-high (5-6 times) (p < 0.001). The adjusted rate ratios were 1.69 in the NOE-middle and 1.77 in the NOE-high (p < 0.001). The AOR for periodontal treatment was 1.23 in the NOE-middle and NOE-high (p < 0.001).
Frequent NOEs lead to undergoing dental scaling and dental treatment, highlighting the importance of encouraging NOE attendance to improve population oral health. Expanding the scope of dental coverage for preventive intervention combined with NOE could help encourage greater participation and promote preventive oral healthcare.
韩国的国民健康筛查（NHS）计划通过早期发现口腔疾病来进行初级预防，从而更便于管理。洁牙有助于预防口腔疾病和治疗早期牙周病。本研究通过对 NHS 中全国口腔检查（NOE）的 19 年随访，评估了其对预防性口腔卫生保健和牙科治疗的影响。
我们对 2002 年至 2003 年期间参加韩国国家健康保险服务的≥19 岁的韩国成年人（n=4669107；男性 2518704 人，女性 2150403 人）进行了纵向观察。自变量包括跟踪 2002 年至 2003 年招募的接受 NOE 的人数，直至 2013 年。因变量涉及 2014 年至 2020 年期间的洁牙次数和牙周及龋齿治疗的有无。
在随访期间接受 6-7 次洁牙的个体，NOE 中等（3-4 次）组的调整后优势比（AOR）为 2.91，NOE 高（5-6 次）组为 3.30（p<0.001）。NOE 中等和高组的调整后率比分别为 1.69 和 1.77（p<0.001）。NOE 中等和高组牙周治疗的 AOR 分别为 1.23 和 1.23（p<0.001）。
频繁的 NOE 可导致接受洁牙和牙科治疗，这强调了鼓励接受 NOE 以改善人群口腔健康的重要性。扩大预防性干预的牙科覆盖范围并结合 NOE，可以帮助鼓励更多人参与并促进预防性口腔保健。
