TMJD EXAM QUESTIONS AND 100% CORRECT
ANSWERS
Cardinal signs of temporomandibular dysfunction (TMD) - Answer -Pain around joint/in
jaw
-Clicking around joint
-Crepitus (grating rough sound produced by the friction of the bones)
-Limitation of movement
Other signs and symptoms of temporomandibular dysfunction (TMD) - Answer
-Headache
-Stiffness in jaw in morning
-Pain on chewing/yawning
-Earache
-Tinitus (ringing in the ear)
-Neck ache
-Dizziness (Subjective)
Define temporomandibular dysfunction (TMD) - Answer Group of disorders of the
temporomandibular joint or its musculature (hence we say TMD not TMJD as that is
specific to the joint problem)
Aetiology of TMJD - Answer -Anatomic (including occlusion and TMJ)
-Neuromuscular (muscle problems)
-Psychological (stress/anxiety/other issues)
Factors that predispose, initiate or perpetuate/sustain TMD - Answer Predispose:
, -Systemic: tetanus, osteoporosis (generalised), inflammatory conditions
-Psychological: *Type A personality* (always stressed)
-*Structural: aplasia of joint - no joint at all* = causes limitation of joint
--> can be issues reg. the disk size, joint dislocation
Initiate:
-*Trauma* (blow on the jaw/fracture of condylar process)
-Overload
-Parafunction (grinding of teeth - *bruxism**)
Perpetuate:
-Behavioural (biting nails, pens)
-*Stress*
-*General health* (rheumatoid arthritis or general arthritis)
-Social
2 types of TMD - Answer -Myogenic (muscle-associated) --> can be treated by dentists
-Arthralgic (joint-associated) --> can't really be treated by dentists
Temporomandibular joint disorders - Answer -Artritides (i.e. any of several inflammation
of joints)
--> Osteoarthritis
-Jaw fracture esp condylar process
-Congenital or developmental disorders: aplasia/hypo/hyper or neoplasia of muscle or
joint
-Ankylosis (of joint = stiffness of joint due to abnormal adhesion of the bones - can be
due fracturing of condyle)
