Tobacco smoking has been shown to be a major risk factor for tooth loss. The present study was designed to examine tooth mortality and the patterns of tooth loss in smokers and nonsmokers over a wide age range in a selected population from Sana'a, Yemen.
A total of 2506 persons between the ages of 15 and 64 years were examined, and every permanent tooth was assessed. Missing teeth included both extracted and missing teeth. Individuals currently smoking one or more boxes of cigarettes (20 cigarettes) a day for 5 years were considered as smokers, whereas individuals with no smoking history were considered as nonsmokers.
Smokers had a higher mean tooth loss than nonsmokers. The difference was statistically significant at p < 0.001. Mean tooth loss was significantly higher in smokers across all age groups, except for those in the 45-54 years age group. Smokers had a significantly higher mean upper tooth loss than nonsmokers. Tooth loss decreased from the incisors to the canines and then increased, with peak loss in the first molars.
Tooth loss among smokers is significantly higher than among nonsmokers. The central incisors, lateral incisors and first molars were the most commonly missing teeth in smokers, compared with nonsmokers.
吸烟已被证明是牙齿脱落的主要风险因素。本研究旨在调查也门萨那特定人群中吸烟者和非吸烟者在较宽年龄范围内的牙齿死亡率及牙齿脱落模式。
对2506名年龄在15至64岁之间的人进行了检查，并对每颗恒牙进行了评估。缺失牙包括拔除的牙齿和自然缺失的牙齿。每天吸食一盒或多盒香烟（20支）达5年的个体被视为吸烟者，而无吸烟史的个体被视为非吸烟者。
吸烟者的平均牙齿脱落数高于非吸烟者。差异具有统计学意义（p < 0.001）。除45 - 54岁年龄组外，所有年龄组吸烟者的平均牙齿脱落数均显著更高。吸烟者上颌牙齿的平均脱落数显著高于非吸烟者。牙齿脱落从门牙到尖牙逐渐减少，然后增加，第一磨牙的脱落率最高。
吸烟者的牙齿脱落率显著高于非吸烟者。与非吸烟者相比，吸烟者中最常缺失的牙齿是中切牙、侧切牙和第一磨牙。
