- Psychological factors
what would you assess in a TMJ examination?
lateral pole of TMJ
temporalis
masseter
mouth opening
soft tissues
what are you looking for when you palpate the lateral pole of the TMJ?
- Does it elicit familiar pain?
3 repetitions each of opening, closing, lateral, protrusive movements: - Any noises palpable?
- Any noises audible to the patient?
how do you palpate the temporalis?
with teeth clenched above ear and forwards above eye
what do you assess with mouth opening?
- Deviation on opening
- Extent of opening – unassisted and assisted.
*Should be 40mm incisal overlap
what do you assess in the intra-oral soft tissues?
- Ridging buccal mucosa at level of occlusal plane.
- Scalloping of borders of tongue.
- Tooth wear
what ways can you investigate TMD?
- Plain radiographs not normally indicated.
- CBCT
- MRI
What are the 2 types of pain related TMD?
myalgia
arthralgia
what is pain of muscle origin, affected by jaw movement, function or parafunction AND replication of this pain on provocation testing of the masticatory muscles?
myalgia
what is a history of myalgia?
pain in jaw, temple, in front of ear or in the ear AND modified jaw movement, function/ parafunction
what does myalgia present as upon examination?
confirmation of pain location (s) in the temporalis/ masseter AND familiar in masseter/ temporalis with at least one of the provocation tests:
- Palpation of temporalis/ masseter
- Maximum unassisted/ assisted opening movements
what are the sub types of myalgia?
local, myofascial pain, myofascial pain with referral
what is pain of joint origin affected by jaw movement, function or parafunction AND replicated by provocation testing of the TMJ?
arthralgia
what is a history of arthralgia?
pain in the jaw, temple, ear or in front of the ear in the past month AND pain modified with jaw movement, function, and parafunction
what would you see upon examination of arthralgia?
confirmation of pain location in area of TMJ (s) AND familiar pain on:
- Palpation of lateral lobe
- Maximum unassisted or assisted opening, right or left lateral or protrusive movements
what are the types of intra-articular TMD?
disc displacement with reduction
disc displacement without reduction with limited opening
degenerative joint disease
subluxation
what is in closed mouth position the disc is in an anterior position relative to the condylar head and the disc reduces on mouth opening?
disc displacement with reduction
what is a history of disc displacement with reduction?
‘noise’ in the past 30 days in movement/ function OR report of any noise during examination
what would you see upon examination of disc displacement with reduction?
clicking, popping, snapping during opening and closing on palpation during at least 1 of the 3 repetitions.
OR
Clicking, popping, snapping during opening or closing on palpation during at least 1 of the 3 repetitions.
AND
clicking, popping, snapping during opening and closing on palpation during at least 1 of the 3 repetitions of left/ right lateral or protrusive movements.
what is the disc does not reduce with opening, persistent limited mandibular movement which does not reduce when the patient or clinician performs a manoeuvre. Closed lock?
disc displacement without reduction with limited opening
