Temporomandibular disorder (TMD), or temporomandibular joint (TMJ) syndrome, is the most common cause of facial pain after toothache. In the past, many physicians called this condition TMJ disease or TMJ syndrome. No unequivocal definition of the disease exists, and two classification schemes are used. The American Academy of Orofacial Pain (AAOP) classification divides TMD broadly into two syndromes:

  • Muscle-related TMD (myogenous TMD), sometimes called TMD secondary to myofascial pain and dysfunction

  • Joint-related (arthrogenous) TMD, or TMD secondary to true articular disease

Of note, these two types often coexist in one patient, making diagnosis and treatment more challenging. What do you know about TMD? Test yourself with this quick quiz.
