Abstract：
This study aims to determine the association between UpH (<5.5), Community Periodontal Index (CPI), and the number of remaining teeth-cumulative indicators of oral health-using data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES, 2016-2018), which represents the Korean population. Data from 12,689 adults aged 19 years and older who had periodontal examinations were analyzed. Logistic regression analysis was performed after adjusting for demographic, health, and health-related behavioral factors as covariates to determine the association between UpH, CPI, and the number of remaining teeth. This study found that UpH (<5.5) was associated with CPI and the number of remaining teeth. For UpH (<5.5), the odds ratio for CPI (≥4 mm) was 1.19 times (95% CI: 1.06-1.33). The risk of tooth loss was 1.25 times (95% CI: 1.06-1.48) for those with 0-19 remaining teeth and 1.20 times (95% CI: 1.07-1.34) for those with 20-27 teeth. The results revealed an association between UpH, CPI, and the number of remaining teeth. However, further longitudinal research on UpH and oral status is necessary.
摘要：
本研究旨在确定UpH（<5.5），社区牙周指数（CPI），以及来自第七届韩国国家健康和营养检查调查的口腔健康使用数据的剩余牙齿累积指标数量(KNHANES，2016-2018），代表韩国人口。分析了12,689名19岁及以上进行牙周检查的成年人的数据。在调整人口统计后进行Logistic回归分析，健康,和健康相关的行为因素作为协变量来确定UpH，CPI,以及剩余牙齿的数量。这项研究发现，UpH（<5.5）与CPI和剩余牙齿数量有关。对于UpH（<5.5），CPI比值比(≥4mm)为1.19倍(95%CI:1.06-1.33).牙齿脱落的风险是0-19颗牙齿的1.25倍（95％CI：1.06-1.48），是20-27颗牙齿的1.20倍（95％CI：1.07-1.34）。结果表明，UpH值之间存在关联，CPI,以及剩余牙齿的数量。然而,需要进一步纵向研究UPH和口腔状况。
