Plaque biofilm is a major etiologic factor of periodontitis, and its effective removal prevents or ameliorates the disease. However, toothbrushing alone does not sufficiently clean the interdental area, and additional interdental cleaning is required to completely remove the plaque from this locale. This cross-sectional study aimed to assess the association of interdental cleaning on the prevalence of periodontitis in a large urban Thai adult cohort.
Interdental cleaning data were retrieved from a dental survey of 1,743 employees of the Electricity Generating Authority of Thailand (EGAT) in 2019. The Centers for Disease Control and Prevention/American Association of Periodontology (CDC/AAP) periodontal case definitions were applied. The participants were subdivided into two groups as those with or without periodontitis depending on their oral health status assessed by calibrated professional examiners. The proportion of subjects who performed interdental cleaning was assessed through a self-reported questionnaire by frequency (daily/ ≥ 1 per week/ none) and profile (correct/ incorrect) of interdental cleaning. Then, the association between interdental cleaning and periodontitis was calculated using logistic regression analysis controlling for the common risk factors of periodontitis such as age, sex, education, smoking, and diabetes.
Participants who performed interdental cleaning on a daily basis and ≥ 1 per week were 27.5% (95% CI: 25.4, 29.6) and 29.1% (95% CI: 27.0, 31.3), respectively while the remainder did not practice. Of those who used interdental cleaning, about one-half focused on sites with food impaction. There was a significant 44% lower prevalence of periodontitis (adjusted odds ratio of 0.56 (95%CI: 0.40, 0.79) in the cohort with a frequent and correct group.
Our data indicate an inverse association between interdental cleaning and periodontitis, particularly in those who routinely adhered to it. Regular interdental cleaning is likely to have a salutary effect on oral health.

菌斑生物膜是牙周炎的主要病因，有效清除可预防或改善疾病。然而，仅靠刷牙并不能充分清洁牙间隙，需要进行额外的牙间隙清洁以彻底清除该部位的菌斑。本横断面研究旨在评估在泰国一个大型城市成年人群中，牙间隙清洁与牙周炎患病率之间的关联。
从 2019 年泰国发电局（EGAT）的一项牙科调查中获取牙间隙清洁数据。应用疾病控制与预防中心/美国牙周病学会（CDC/AAP）牙周病病例定义。根据经过校准的专业检查者评估的口腔健康状况，将参与者分为牙周炎组和非牙周炎组。通过自我报告问卷，根据牙间隙清洁的频率（每日/≥每周一次/无）和正确/不正确情况评估进行牙间隙清洁的受试者比例。然后，通过逻辑回归分析控制牙周炎的常见危险因素（如年龄、性别、教育程度、吸烟和糖尿病），计算牙间隙清洁与牙周炎之间的关联。
每天和每周至少一次进行牙间隙清洁的参与者分别占 27.5%（95%CI：25.4, 29.6）和 29.1%（95%CI：27.0, 31.3），其余的则没有进行牙间隙清洁。在使用牙间隙清洁的人群中，大约有一半的人关注有食物嵌塞的部位。在经常且正确使用牙间隙清洁的人群中，牙周炎的患病率显著降低了 44%（调整后的优势比为 0.56（95%CI：0.40, 0.79）。
我们的数据表明，牙间隙清洁与牙周炎之间呈负相关，特别是在那些经常且正确使用牙间隙清洁的人群中。定期进行牙间隙清洁可能对口腔健康有益。
