Question Answer
T/F: The exact etiology of the most common TMDs is unknownTrue
Which of the following occlusal discrepencies has shown to have a strong assocition with TMD's discrepancies between centric relation and centric occlusion, nonworking side occlusal interferences, and Angle's occlusal classification?None of the above
T/F: pain might be a factor in producing the occlusal changes that are sometimes reported by patients with TMDsTrue (apparently)
T/F: treatment for TMD should be reversibleTrue
T/F: according to studies, muscle hyperactivity/bruxism causes TMD painFalse
T/F: Psychological disorders are a common cause of TMDFalse
T/F: Psychological distress associated with TMD patients is most likely caused by the chronic TMD painTrue
Myofascial pain with arthralgia and myofascial pain were only associated with what related (risk) factors?trauma, clenching, third molar removal, somatization, and female gender
Although the prevalence of one or more signs of mandibular pain and dysfunction is high in the population, only about ___% have symptoms severe enough to require treatment6%
Available evidence suggests TMD is more prevalent in what age group and what gender?20-40 yo; females
T/F: RDC/TMD were designed to allow standardization and replication of research into the most common forms of muscle and joint-related TMDTrue
Disc disorders are now differentiated on the basis of what type of imaging?MRI (arthrotomography)
diagnosis of ____ ____ ___ ___ ___ ____ may be the most problematic diagnosis without imagingchronic articular disc displacement without
what is chronic pain disorder characterized by pain localized to teeth or gingiva, has been considered to be a variant of AFP ("phantom tooth pain")Atypical odontalgia

Match with clinical findings

Question Answer
History: none; Reciprocal click, No coarse crepitus; Passive stretch >40 mm; Lateral movements; >7 mmnormal
No contributory history; clinical exam finds reciprocal click or popping noise, no course crepitus, and passive stretch 35-40 mm normal translation of ipsilateral condylesADD with reduction
Physical examination shows no reciprocal click, no coarse crepitus, maximum opening less than 35 mm; decreased translation of ipsilateral condyle and no osseous changesADD WITHOUT reduction
Tomography shows decreased translation of condyle and osseous changesChronic ADD WITHOUT reduction
