OBJECTIVE
Second-hand smoke (SHS) is considered a risk factor for a number of oral diseases. However, its influence on tooth loss, which is the final consequence of periodontal disease and caries, remains unknown. We aimed to evaluate the association between SHS experience and the number of remaining teeth among non-smoking older Japanese individuals.
METHODS
Cross-sectional data from the Japan Gerontological Evaluation Study (JAGES) 2013 were used. From the 27,561 people ≥65 years of age who responded to a self-reported questionnaire (response rate = 71.1%), data of 18,865 respondents who had never smoked were analysed. Multinomial logistic regression with multiple imputations was applied to estimate the odds ratio of the frequency of SHS exposures on the number of remaining teeth.
RESULTS
The prevalence of participants with ≥20 teeth, 10-19 teeth, 5-9 teeth, 1-4 teeth, and no teeth were 53.2%, 20.4%, 9.9%, 6.6%, and 9.9%, respectively. The proportion of participants with SHS was 37.5%. After adjusting for sex, the SHS experience tended to be associated with a lower risk of having the fewer number of remaining teeth (P < 0.05). However, after being adjusted for age and sex, participants with SHS exposure at "a few times a week" and "almost every day" were significantly associated with the fewer number of teeth. After adding all other covariates, compared to the participants without any exposure to SHS, the odds ratio for having no teeth rather than having ≥20 teeth among the participants with daily exposure to SHS was 1.35 (P < 0.01).
CONCLUSION
Daily second-hand smoke was significantly associated with fewer remaining teeth based on the self-reported survey among older Japanese people.
目的
二手烟（SHS）被认为是许多口腔疾病的危险因素。然而，其对牙齿缺失的影响（牙周病和龋齿的最终后果）尚不清楚。我们旨在评估非吸烟的老年日本个体中 SHS 暴露经历与剩余牙齿数量之间的关联。
方法
使用日本老年评估研究（JAGES）2013 的横断面数据。从回答自我报告问卷（应答率=71.1%）的 27561 名≥65 岁人群中，分析了从未吸烟的 18865 名受访者的数据。应用多次插补的多变量逻辑回归估计 SHS 暴露频率对剩余牙齿数量的比值比。
结果
≥20 颗牙齿、10-19 颗牙齿、5-9 颗牙齿、1-4 颗牙齿和无牙齿的参与者比例分别为 53.2%、20.4%、9.9%、6.6%和 9.9%。有 SHS 经历的参与者比例为 37.5%。在校正性别后，SHS 经历与剩余牙齿数量较少的风险呈负相关（P<0.05）。然而，在校正年龄和性别后，每周几次和几乎每天暴露于 SHS 的参与者与牙齿数量较少显著相关。在添加所有其他协变量后，与没有任何 SHS 暴露的参与者相比，每天暴露于 SHS 的参与者中无牙的可能性是非每天暴露于 SHS 的参与者的 1.35 倍（P<0.01）。
结论
基于日本老年人的自我报告调查，每天接触二手烟与剩余牙齿数量较少显著相关。
