For TMJ dysfunction, which statement about prevalence is true?

• A. The condition is more common in females
• B. It is more common in males
• C. It affects males and females equally
• D. It is rare in both genders

Answer: (A)

The main concept here is the gender pattern seen with TMJ dysfunction. In practice, this condition is more common in females, with studies showing roughly two to three times higher prevalence in women, especially among young and middle-aged adults. Hormonal factors, such as estrogen effects on joint tissues, along with differences in muscle activity, bruxism, and psychosocial stress, are thought to contribute to this disparity. While men can be affected, and the disorder is not rare in either sex, the stronger, more consistent finding is female predominance. The other statements don’t match what is typically observed epidemiologically, as it is not more common in males, not equal between genders, and not rare in both.
