To ascertain whether interdental cleaning behaviours of Australian adults were associated with lower levels of plaque, gingivitis and periodontal disease.
Data were obtained from the National Survey of Adult Oral Health 2004-06. Outcome variables were three indicators of oral hygiene outcomes (the presence or not of dental plaque, dental calculus and gingivitis) and two of periodontal disease (the presence or not of at least one tooth with a periodontal pocket or clinical attachment loss of ≥ 4 mm). The independent variable was classified into the following three groups: regularly clean interproximally 'at least daily' (daily+); 'less than daily' (< daily); and 'do not regularly clean interproximally' (reference group). Poisson regression with robust variance estimation was used to calculate prevalence ratios (PRs) and 95% confidence intervals (95% CIs) relative to the reference group, adjusted for covariates.
Regular self interdental cleaning was associated with less dental plaque (< daily, PR = 0.89, 95% CI = 0.84, 0.95; and daily+, PR = 0.89, 95% CI = 0.82, 0.96), less dental calculus (< daily, PR = 0.88, 95% CI = 0.80, 0.97; and daily+, PR = 0.79, 95% CI = 0.70, 0.89) and lower levels of moderate/severe gingivitis (daily+, PR = 0.85, 95% CI = 0.77, 0.94). Periodontal pocketing was less likely for the < daily group (PR = 0.61, 95% CI = 0.46, 0.82), but was not associated with daily+ cleaning (PR = 0.99, 95% CI = 0.663, 1.49). There was not a significant association between interdental cleaning and clinical attachment loss (< daily, PR = 0.90, 95% CI = 0.77, 1.05; and daily+, PR = 1.17, 95% CI = 0.95, 1.44).
Regular interdental cleaning was associated with better oral hygiene outcomes, such as dental plaque and gingivitis, although there was no significant association between regular interdental cleaning and clinical attachment loss.
本研究旨在确定澳大利亚成年人的邻间清洁行为是否与较低水平的菌斑、牙龈炎和牙周病有关。
数据来自于 2004-2006 年的全国成人口腔健康调查。主要结局变量为口腔卫生结局的三个指标（是否存在牙菌斑、牙石和牙龈炎）和牙周病的两个指标（是否至少有一颗牙齿存在牙周袋或临床附着丧失≥4mm）。自变量分为以下三组：“每日至少清洁一次”（每日+）；“每日清洁次数少于一次”（<每日）；“不规律清洁邻间”（参照组）。采用具有稳健方差估计的泊松回归计算相对于参照组的患病率比（PR）及其 95%置信区间（95%CI），并对协变量进行校正。
规律的自我邻间清洁与较少的牙菌斑（<每日，PR=0.89，95%CI=0.84，0.95；每日+，PR=0.89，95%CI=0.82，0.96）、较少的牙石（<每日，PR=0.88，95%CI=0.80，0.97；每日+，PR=0.79，95%CI=0.70，0.89）和较低水平的中度/重度牙龈炎（每日+，PR=0.85，95%CI=0.77，0.94）有关。与每日+清洁相比，<每日清洁组牙周袋的可能性较小（PR=0.61，95%CI=0.46，0.82），但与每日+清洁无关（PR=0.99，95%CI=0.663，1.49）。邻间清洁与临床附着丧失无显著相关性（<每日，PR=0.90，95%CI=0.77，1.05；每日+，PR=1.17，95%CI=0.95，1.44）。
规律的邻间清洁与更好的口腔卫生结局有关，如牙菌斑和牙龈炎，但与临床附着丧失之间无显著相关性。
