背景：吸烟与牙周病之间的因果关系已经确定。本研究探讨吸烟和牙齿脱落之间的关联，使用国家数据库在Japanes.Methods：记录的牙科疾病调查和全国营养调查在1999年以电子方式使用共同的标识。使用logistic回归模型分析了3，999名年龄超过40岁的受试者的记录，控制了混杂因素，如年龄，刷牙频率，体重指数，饮酒量以及维生素C和E的摄入量。男性（45.6%）和女性（7.8%）的吸烟率不同。非吸烟者、既往吸烟者和当前吸烟者的牙齿脱落率在男性中分别为28.5%、38.6%和36.9%，在女性中分别为38.6%、34.3%和38.9%。控制吸烟状态混杂因素的现有牙齿的校正平均值在男性中分别为21.5、19.7和18.2，在女性中分别为19.0、19.2和16.4。牙齿脱落的相关性在前吸烟者中不显著，但在当前吸烟者中显著：调整后的优势比（95%可信区间）男性和女性相对于非吸烟者为1.29既往吸烟者分别为0.92-1.80和0.86（0.46，1.60），现吸烟者分别为2.22（1.61-3.06）和2.14（1.45-3.15）。终生暴露与牙齿脱落之间存在剂量-反应关系（P趋势
Background: A causal association between cigarette smoking and periodontal disease has been established. The present study examined the association between smoking and tooth loss using national databases in Japan.Methods: Records of the Survey of Dental Diseases and the National Nutrition Survey in 1999 were linked electronically using common identification. Records of 3,999 subjects aged older than 40 years were analyzed using logistic regression models, controlling for confounding factors, such as age, frequency of tooth brushing, body mass index, alcohol consumption, and intakes of vitamin C and E.Results: Prevalence of tooth loss in terms of having less than 19 existing teeth was 37.3% overall. Smoking rates differed in males (45.6%) and females (7.8%). The prevalence of tooth loss in nonsmokers, former, and current smokers was 28.5%, 38.6%, and 36.9% in males, and 38.6%, 34.3% and 38.9% in females, respectively. Adjusted means of existing teeth controlling for confounders by smoking status were 21.5, 19.7 and 18.2 in males and 19.0, 19.2 and 16.4 in females, respectively. The association of tooth loss was non-significant in former smokers but significant in current smokers: adjusted odds ratios (95% confidence intervals) relative to nonsmokers in males and females were 1.29 (0.92-1.80) and 0.86 (0.46, 1.60) for former smokers and 2.22 (1.61-3.06) and 2.14 (1.45-3.15) for current smokers, respectively. A dose-response relationship between lifetime exposure and tooth loss was seen (P for trend
