Smoking has been associated with the number of natural teeth a person has and with the likelihood of periodontitis. The purpose of this study was to determine the relationships between the number of teeth present and periodontal diseases with smoking habits in a cohort of Japanese men.
The study group comprised 1088 men, 40-75 years of age. Oral examinations were conducted in dental clinics. Information on smoking status and on oral health behavior was collected from self-administered questionnaires. The relationship between oral health status and smoking status was estimated using adjusted odds ratios.
Compared with those whom had never smoked, the odds ratios of having more than eight missing teeth and having periodontitis, among current smokers, were 1.67 and 1.74, respectively. In those who had stopped smoking for 11 years or longer, there was no increase in the odds ratio of having more than eight missing teeth and periodontitis, compared with those whom had never smoked.
Smoking has a positive association with missing teeth and periodontitis. However, smoking cessation is beneficial for oral health. The odds of having more than eight missing teeth, or of having periodontitis, in those who had never smoked was similar to that of individuals who reported that they had stopped smoking for 11 years or more.
吸烟与一个人拥有的天然牙齿数量以及牙周炎的可能性有关。本研究的目的是确定在日本男性队列中，现有的牙齿数量与牙周疾病与吸烟习惯之间的关系。
研究组包括 1088 名年龄在 40-75 岁之间的男性。在牙科诊所进行口腔检查。通过自填问卷收集有关吸烟状况和口腔健康行为的信息。使用调整后的优势比估计口腔健康状况与吸烟状况之间的关系。
与从不吸烟者相比，当前吸烟者的缺失牙数超过 8 颗和患有牙周炎的优势比分别为 1.67 和 1.74。在已经戒烟 11 年或更长时间的人群中，与从不吸烟者相比，缺失牙数超过 8 颗和患有牙周炎的优势比并没有增加。
吸烟与缺失牙和牙周炎呈正相关。然而，戒烟对口腔健康有益。从不吸烟者的缺失牙数超过 8 颗，或患有牙周炎的可能性与报告戒烟 11 年或更长时间的人群相似。
