Smoking is associated with the number of teeth. The purpose of this study was to determine the relationship of number of teeth with smoking and smoking cessation.
Subjects included 547 males aged between 55 and 75 years. Oral examinations were conducted in 2005. Smoking status information was collected from questionnaire surveys conducted in 1990, 1995, 2000, and 2005. The relationship between having more than eight missing teeth and smoking status was estimated with adjusted odds ratio.
Comparing with never smokers, odds ratios of having more than eight missing teeth among current and former smokers were 1.96 and 1.86, respectively. The odds ratios in those who had stopped smoking for <or=10 years was 3.02, and for those who had ceased smoking for 11-20 years was 2.66. In those who stopped smoking for 21 years or more, there was no increase in the odds ratio.
Smoking had a positive association with the number of missing teeth and smoking cessation is beneficial for maintaining teeth. The odds of having more than eight missing teeth in those who had never smoked was equal to that of individuals who reported that they had stopped smoking for 21 years or more.
吸烟与牙齿数量有关。本研究的目的是确定牙齿数量与吸烟及戒烟之间的关系。
研究对象包括547名年龄在55至75岁之间的男性。2005年进行了口腔检查。吸烟状况信息来自于1990年、1995年、2000年和2005年进行的问卷调查。通过调整后的比值比来估计牙齿缺失超过八颗与吸烟状况之间的关系。
与从不吸烟者相比，当前吸烟者和既往吸烟者中牙齿缺失超过八颗的比值比分别为1.96和1.86。戒烟时间≤10年者的比值比为3.02，戒烟11至20年者的比值比为2.66。戒烟21年及以上者的比值比没有增加。
吸烟与牙齿缺失数量呈正相关，戒烟有利于保持牙齿。从不吸烟者中牙齿缺失超过八颗的几率与报告戒烟21年及以上者的几率相当。
