Removal of the biofilm from the proximal space is essential for preventing periodontal disease. This study aimed to prove the association between the use of proximal cleaning devices, such as dental floss and interdental brushes, and periodontal health among nationally representative Korean adults. Data collected from the 7th National Health Nutrition Survey (KNHANES VII: 2016-2018) were used for this purpose. A total of 11,359 participants aged 19 years or older who participated in KNHANES were reviewed. The response variable was the prevalence of high CPI (CPI of 3-4), and the explanatory variables were dental floss and interdental brush. A multivariable logistic regression analysis was performed to adjust for potential confounding factors and to analyze the association between periodontal disease and proximal cleaning devices. It was found that 63.1% of the participants did not use proximal cleaning devices at all, 17.5% used dental floss alone, 11.9% used an interdental brush, and 7.5% used both. Subjects who used both dental floss and interdental brush had a high CPI rate nearly half that of all the models for those who did not. In particular, for those using dental floss, the aOR of high CPI was 0.681 in Model 1, 0.714 in Model 2, and 0.737 in Model 3. Dental hygiene products for cleaning the proximal space, such as dental floss, are essential for removing the dental biofilm as a basic tool along with toothbrushes. Teaching and explaining the need to use these devices well are important for oral health care and maintenance.
清除近中空间的生物膜对于预防牙周病至关重要。本研究旨在证明在韩国成年人中，使用牙线和牙间刷等近中清洁器械与牙周健康之间的关联。为此，使用了 2016-2018 年第七次全国健康营养调查（KNHANES VII）的数据。共纳入 11359 名年龄在 19 岁及以上、参加 KNHANES 的参与者。因变量为高 CPI（CPI 为 3-4）的患病率，解释变量为牙线和牙间刷。采用多变量逻辑回归分析调整潜在混杂因素，并分析牙周病与近中清洁器械的关系。结果显示，63.1%的参与者根本不使用近中清洁器械，17.5%单独使用牙线，11.9%使用牙间刷，7.5%两者都用。与所有不使用近中清洁器械的模型相比，同时使用牙线和牙间刷的受试者 CPI 高的比例接近一半。特别是对于使用牙线的受试者，在模型 1 中，高 CPI 的调整优势比（aOR）为 0.681，在模型 2 中为 0.714，在模型 3 中为 0.737。作为基本工具，牙线等用于清洁近中空间的口腔卫生产品对于清除牙菌斑至关重要。教授并解释这些器械的正确使用方法对于口腔健康护理和维护非常重要。
