Title Smoking Tobacco Does Not Increase Incidence or Severity of TMJ Pain
Clinical Question In adult patients, do tobacco smokers experience greater TMJ pain than nonsmokers?
Clinical Bottom Line If a smoking patient reports with TMD, having them discontinue their smoking habit should not be the only treatment given to them. Smoking alone can’t be considered the only factor that causes TMD patients to experience more pain when compared to nonsmokers. (See Comments on the CAT below)

#1) 16106714Wanman/2005Tobacco smokers and nonsmokers with TMJ painCohort Study
Key resultsIn this study 244 smokers were matched with nonsmokers based on age, gender, number of teeth, educational level, and area of residence. At the beginning and end of the study 30% of the subjects reported mild TMD symptoms. Pain in the jaws and more intense TMD pain was reported by 15% of the subjects. Finally, there were no noteworthy differences found between smokers and nonsmokers concerning the course of the symptoms or signs of the TMD seen during the 6 year study.

Comments on
The Evidence
The subjects that were paired together in this study were clearly defined from the beginning and matched well together. The 6 year follow-up period was long enough to get acceptable results for the evaluation of pain differences. Having the patients that reported as smokers stop smoking and then reexamining them would make this study even better.
Applicability In smoking patients that report with pain in their TMJ, advising them to stop smoking probably would not be the best option to reduce their TMJ pain. There are better treatment options available to TMD patients, and quitting their tobacco smoking habit wouldn’t remove the discomfort felt in their TMJ.
