The purpose of this study was to evaluate the mitigating effect of the use of interdental brushes on periodontal health inequality.
This study was based on the data acquired in the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI; 2013-2015). A total of 17,583 participants (7,633 males and 9,950 females)) aged 19 years or older completed the KNHANES VI between 2013 and 2015. Multivariable logistic regression analysis was performed using socioeconomic characteristics (sex, age, level of education, individual income), personal health practice (smoking, toothbrushing, dental flossing, interdental brushing, dental clinic visiting), systematic medical factors (diabetes mellitus, hypercholesterolemia, hypertension, obesity) and the community periodontal index. We confirmed differences in the prevalence of periodontal disease with the use of an interdental brushes stratified according to individual income.
Three logistic regression models adjusted for covariates hierarchically. In all models, individuals who used an interdental brush were not significantly different from individuals who did not use an interdental brush. The adjusted odds ratio (OR) for interdental brushing was 0.918 with a 95% confidence intervals (CIs) of 0.797-1.057. When periodontal disease was the outcome of the model, the lowest income group had 1.266 (95% CIs 1.066 to 1.502) times the odds of having periodontal disease than the highest income group. In interdental brush nonusers, the lowest income group had 1.276 (95% CI 1.061-1.533) times the odds of having periodontal diseases than the highest income group. However, in the interdental brush users, there were no significant differences in periodontal disease prevalence among income groups.
The results suggest that the use of interdental brushes could alleviate periodontal health inequality.
本研究旨在评估使用牙间刷对牙周健康不平等的缓解作用。
本研究基于 2013-2015 年韩国第六次全国健康与营养调查（KNHANES VI）的数据。共有 17583 名年龄在 19 岁及以上的参与者（男性 7633 名，女性 9950 名）完成了 2013 年至 2015 年期间的 KNHANES VI。使用社会经济特征（性别、年龄、教育程度、个人收入）、个人健康行为（吸烟、刷牙、牙线洁牙、牙间刷洁牙、看牙医）、系统医学因素（糖尿病、高胆固醇血症、高血压、肥胖）和社区牙周指数，对多变量逻辑回归分析进行了分析。我们根据个人收入分层，确认了使用牙间刷对牙周病患病率的差异。
对协变量进行分层的三个逻辑回归模型。在所有模型中，使用牙间刷的个体与未使用牙间刷的个体没有显著差异。牙间刷的调整后比值比（OR）为 0.918，95%置信区间（CI）为 0.797-1.057。当牙周病为模型的结果时，最低收入组比最高收入组发生牙周病的几率高 1.266（95%CI 1.066-1.502）倍。在牙间刷非使用者中，最低收入组比最高收入组发生牙周病的几率高 1.276（95%CI 1.061-1.533）倍。然而，在牙间刷使用者中，不同收入组之间牙周病的患病率没有显著差异。
研究结果表明，使用牙间刷可能会减轻牙周健康不平等。
