文献曾记载吸香烟可预防阿弗他溃疡,Axell等(1985)提出无烟烟草(ST,指嚼烟草和鼻烟)可使嗜用者的溃疡复发率降低。为证实ST是否确有预防作用,对1 457名垒球职业队员进行了研究,受检查者均为17～63岁男性,545人为ST嗜用者(近数周内嗜用),244人曾有ST嗜用史,643人无嗜好,另25人嗜吸香烟,凡用ST者受检前漱口2遍,检查者不知道受检对象是否嗜烟,检查结果用卡方检验阿弗他性溃疡发生率与嗜ST、年龄、种族、吸香
It has been documented in the literature that smoking cigarettes can prevent aphthous ulcers and that Axell et al. (1985) suggested that smokeless tobacco (ST, finger tobacco and snuff) can reduce the recurrence rate of ulcers in the addicts. In order to confirm whether ST has a preventive effect, a total of 1 457 softball pro players were studied. All subjects were 17-63 years old, 545 were ST addicts (recent weeks' addictions), 244 were ST history of abuse, 643 people no hobbies, the other 25 people addicted to smoking cigarettes, who used ST before the mouth gargle 2 times, the examiner does not know whether the subjects smoked, check the results of aphrodity with chi-square test Ulcer incidence and addiction ST, age, race, absorption of incense
