Title TMD Signs and Symptoms Increase in Dental Students After 1 Year of Dental School, Especially in Women
Clinical Question Are TMD symptoms related to stress increased in 2nd year dental students compared to entering dental students?
Clinical Bottom Line At the end of the study the 1-year incidence of muscle signs and symptoms increased significantly for both sexes of dental students, and the increase was even more significant for women; however, whether or not stress contributed to this increase was not clearly demonstrated.

Key resultsThe incidence of myofascial pain was assessed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). 308 dental students were surveyed before beginning dental school and again upon entering their 2nd year. The prevalence of muscular signs and symptoms increased in both sexes of dental students, but when a sub-analysis was done, breaking down the data between men and women, there was a significant increase seen in women. For instance, 76% of the original 30% of the total population who experienced incidence of muscle signs and symptoms were women. Similar findings with large gaps between the sexes were seen throughout the study.

The Evidence
Validity: The paper demonstrates a marked increase in incidence of myofascial pain using a well-known measure of TMD signs and symptoms, the RGC/TMD, in the dental students throughout the 1st year of dental school.
Applicability This study suggests that dental students are vulnerable to developing TMD. This study could be used by faculty to justify discussing with incoming dental students ways to prevent developing TMD symptoms. Discussion of TMD self-management strategies should be employed among other topics dealing with the TMJ.
