PMID 30936634WHAT IT FOUND
In university professors, headache and temporomandibular disorder symptoms occurred independently, with no association found between the two.
Males reported headaches more frequently, while females reported more intense symptoms. This small survey suggests these conditions may coexist without being causally linked in this group.
Key findings
01No association was found between primary headache and temporomandibular disorder in the studied university professors.
02Headaches were reported more frequently by males (35.7%) than females (23%), but females reported more intense pain (66.6% moderate vs 20% moderate in males).
03Most participants (71.4% of males and 76.9% of females) reported no facial pain in the previous four weeks.

What it does not show
Very small sample size (27 participants) limits generalizability and statistical power. Single-center study at a private university, restricting applicability to other populations. Short one-week follow-up period may miss episodic patterns. High non-response rate (8 of 35 did not return questionnaires) may introduce selection bias. No Axis I physical examination of TMD was reported, relying solely on self-reported symptoms.
Declared interests
The authors report no conflicts of interest.
The easy way to misread this
Do not conclude that TMD treatment will reduce headache frequency or intensity based on this paper. The study found no association between the two conditions, so assuming a causal link or expecting dual benefits from treating one condition is not supported by these data.
