Which statement best describes TMD epidemiology?

Which statement best describes TMD epidemiology?

• A. Most common in 20-40-year-olds and more common in women.
• B. Most common in children and more common in men.
• C. Most common in elderly men.
• D. Most common in 30-50-year-old women.

Answer: (A)

Temporomandibular disorders show a clear epidemiologic pattern: they are more common in women and tend to present in young to middle-aged adults. This makes the statement describing TMD as most common in 20-40-year-olds and more common in women the best description. While men and older individuals can be affected, these groups are less representative of the overall epidemiology. The other options either emphasize age groups outside the typical peak or attribute TMD to populations with lower observed prevalence.
