We investigated the relationship between secondhand smoke and periodontal disease in nonsmokers.
We undertook a cross-sectional analysis of the Atherosclerosis Risk in Communities study with 2739 lifetime nonsmokers aged 53-74 years, unexposed to other sources of tobacco, who received a complete periodontal examination at visit 4. Exposure was reported as average hours per week in close contact with a smoker in the preceding year. We defined severe periodontitis as 5 or more periodontal sites with probing pocket depth of 5 millimeters or more and clinical attachment levels of 3 millimeters or more in those sites. Other outcomes were extent of periodontal probing depths of 4 millimeters or more and extent of clinical attachment levels of 3 millimeters or more.
In a binary logistic regression model, adjusted odds of severe periodontitis for those exposed to secondhand smoke 1 to 25 hours per week increased 29% (95% confidence interval = 1.0, 1.7); for those exposed to secondhand smoke 26 hours per week, the odds were twice as high (95% confidence interval = 1.2, 3.4) as for those who were unexposed.
Exposure to secondhand smoke and severe periodontitis among nonsmokers had a dose-dependent relationship.
我们研究了不吸烟人群中二手烟与牙周病的关系。
我们对动脉粥样硬化风险社区研究进行了横断面分析，该研究纳入了 2739 名年龄在 53-74 岁之间、一生中从不吸烟且未接触其他烟草来源的人群，他们在第 4 次访视时接受了完整的牙周检查。暴露情况根据前一年每周与吸烟者密切接触的平均小时数报告。我们将严重牙周炎定义为 5 个或更多牙周探诊深度为 5 毫米或以上、且这些部位的临床附着水平为 3 毫米或以上的牙周探诊部位。其他结果包括牙周探诊深度为 4 毫米或以上和临床附着水平为 3 毫米或以上的程度。
在二元逻辑回归模型中，每周接触二手烟 1-25 小时的人群发生严重牙周炎的调整比值比增加 29%（95%置信区间=1.0，1.7）；每周接触二手烟 26 小时的人群发生严重牙周炎的比值比是未暴露人群的两倍（95%置信区间=1.2，3.4）。
不吸烟人群接触二手烟与严重牙周炎之间存在剂量依赖性关系。
