CONTEXT
Current evidence shows ambiguous relationship between tobacco use and the occurrence of aphthous.
OBJECTIVES
We studied the relationship between the occurrence of recurrent aphthous ulcers and various forms of tobacco usage.
MATERIALS AND METHODS
A hospital based case control study was carried out in a dental teaching hospital in Cochin, India. One hundred and two outpatient subjects (Males 56.9%) were identified having aphthous ulceration using Natha's diagnostic criteria and were classified as cases. One hundred and eight subjects (Males, 70.4%) with no aphthous ulceration were selected randomly as controls. Exposure ascertainment of tobacco usage was done by structured interview.
RESULTS
The adjusted odd ratio was found to be 0.41 (95% CI 0.19-0.87) for tobacco usage and occurrence of aphthous ulceration compared to non tobacco users. The odds ratio of 0.41 for tobacco usage infers that subjects using tobacco were 59% less likely to have aphthous ulcerations compared to nontobacco users.
CONCLUSION
The tobacco consumers have less frequency of aphthous ulceration compared non users.
背景
目前的证据表明，烟草使用与口疮的发生之间的关系尚不明确。
目的
我们研究了复发性口疮性溃疡的发生与各种形式的烟草使用之间的关系。
材料与方法
在印度科钦的一家牙科教学医院进行了一项基于医院的病例对照研究。使用纳塔的诊断标准确定了102名门诊患者（男性占56.9%）患有口疮性溃疡，并将其分类为病例组。随机选择108名无口疮性溃疡的受试者（男性占70.4%）作为对照组。通过结构化访谈确定烟草使用情况。
结果
与非烟草使用者相比，烟草使用与口疮性溃疡发生的调整后比值比为0.41（95%置信区间0.19 - 0.87）。烟草使用的比值比为0.41，这意味着与非烟草使用者相比，使用烟草的受试者患口疮性溃疡的可能性低59%。
结论
与非使用者相比，烟草消费者患口疮性溃疡的频率较低。
