Introduction:
The relationship between smoking and general body ache has been shown to be bidirectional. The specific association between tobacco consumption and orofacial pain remains unclear, however.
Aim And Methods:
The aim of this systematic review was to explore the association between pain related to diseases of the oral cavity and use of tobacco. A systematic search of PubMed, Embase, Web of Science, and Cochrane databases was carried out in September 2019. Tobacco exposure was included irrespective of the method of consumption (smokeless and smoked tobacco), and frequency of the habit. The outcome was defined as clinically diagnosed or self-reported pain in the orofacial region, with no limitation in the duration of the condition or the site of the pain.
Results:
Altogether, eight studies were selected, with three of them demonstrating good methodology and none of them being of poor quality. Meta-analysis of six studies showed that orofacial pain was significantly worse in tobacco (smoked and smokeless) users (odds ratio [OR] = 3.55, 95% confidence interval [CI]: 1.92, 6.58) in comparison to nonusers. Subgroup analysis showed that the odds of orofacial pain was three times (OR = 3.13, 95% CI: 1.16, 8.46) higher among smokers, but was not associated with smokeless tobacco.
Conclusions:
The odds of experiencing orofacial pain among patients with oral diseases increase for patients who are also smokers. The findings could help dentists and other health specialists more effectively manage patients with orofacial pain who are tobacco consumers.
Implications:
This study shows that the odds of orofacial pain among patients with oral diseases increase for patients who are smokers. The results are a significant contribution to the literature because, while the relationship between smoking and general body ache has been shown to be bidirectional, the specific association between tobacco use and orofacial pain warranted further study. The findings could help dentists and other specialists more effectively manage patients with orofacial pain who are also tobacco consumers.
