Correctional institution inmates have reduced access to dental care; however, a quantitative assessment of their oral health condition has not yet been performed in South Korea. Therefore, this study aimed to assess dental caries and compare the prevalence of dental caries and associated factors between inmates and the general South Korean population.
The dental records of two detention centers in South Korea were retrospectively analyzed to assess the clinical oral health condition of inmates using the Decayed, Missing, and Filled Teeth (DMFT) index and self-reported questionnaire. These data were compared with similar data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) for the general South Korean population.
In total, 642 inmates were analyzed and compared with 13,345 KNHANES participants in the KNHANES. The inmate and KNHANES groups demonstrated significant intergroup differences, with a higher prevalence of untreated caries, DMFT, decayed teeth (DT), and missing teeth (MT) values among the inmates. The prevalence of untreated caries decreased according to the history of dental pain in the inmate group but increased in the KNHANES group. The decrease in DMFT with a history of dental pain was significant only in the inmate group. Furthermore, self-rated oral health was significantly associated with prevalence of untreated caries, DMFT, DT, MT, and filled teeth (FT) in the inmate group but with prevalence of untreated caries, DMFT, DT, and MT in the KNHANES group. It was found that this is because there is an interaction effect by the group.
The oral health of the inmate group was significantly poorer than that of the general group. Since DMFT, DT, MT, and FT values and prevalence of untreated caries in the inmate group were significantly related to their self-rated oral health, suggesting that self-rated oral health should be incorporated into the dental health screenings of correctional institution inmates.
矫正机构囚犯获得的牙科护理较少；然而，韩国尚未对其口腔健康状况进行定量评估。因此，本研究旨在评估龋齿，并比较囚犯和韩国普通人群的龋齿患病率和相关因素。
回顾性分析韩国两个拘留中心的牙科记录，使用龋齿、失牙、补牙（DMFT）指数和自我报告问卷评估囚犯的临床口腔健康状况。将这些数据与韩国全国健康和营养检查调查（KNHANES）中获得的类似韩国普通人群的数据进行比较。
共分析了 642 名囚犯，并与 KNHANES 中的 13345 名 KNHANES 参与者进行了比较。囚犯和 KNHANES 组之间存在显著的组间差异，囚犯组未经治疗的龋齿、DMFT、龋齿（DT）和缺牙（MT）值的患病率较高。在囚犯组中，未治疗的龋齿患病率随着牙科疼痛史的增加而增加，但在 KNHANES 组中则相反。在有牙科疼痛史的情况下，DMFT 的下降仅在囚犯组中具有统计学意义。此外，在囚犯组中，自我评估的口腔健康与未经治疗的龋齿、DMFT、DT、MT 和补牙（FT）的患病率显著相关，但在 KNHANES 组中仅与未经治疗的龋齿、DMFT、DT 和 MT 的患病率相关。发现这是因为组间存在交互效应。
囚犯组的口腔健康明显差于普通组。由于囚犯组的 DMFT、DT、MT 和 FT 值以及未经治疗的龋齿患病率与他们的自我评估口腔健康显著相关，这表明自我评估的口腔健康应纳入矫正机构囚犯的口腔健康筛查。
