Intro to TMDs Flashcards
T/F: TMD is specifically a dental problem.
FALSE
What is the common set of symptoms involved with TMDs?
Pain and jaw dysfunction
T/F: All TMDs share a similar etiology?
FALSE
Similar symptoms; different etiologies
What are the two major divisions of TMDs?
- Extracapsular (non-joint related)
2. Joint related (true TMJ disease)
What system is used to define pain clinically? (LIQ ORA AA)
- Location
- Intensity
- Quality (burning, pulsing, ache)
- Onset
- Radiation of pain
- Associated system
- Alleviating factors
- Aggravating factors
What is a good way to know if a patient has a joint or muscle problem?
If the patient can specifically localize the pain to a point directly in front of the ear, likely joint.
What is local myalgia?
Simply muscle pain
Stiff and sore from overuse
Describe myofascial pain?
Aching pain on the face with trigger points.
Predictable pain referral with trigger point palpation.
What is a myospasm?
Sudden cramping of a muscle
What is centrally mediated myalgia?
Chronic continuous pain with no clinical inflammation
T/F: The TMJ is a load bearing joint.
TRUE
T/F: The articular disk can also be called a meniscus.
FALSE
What disorder is fairly common and often asymptomatic?
Anterior disc displacement
T/F: Anterior disk displacement must be fixed to avoid problems.
FALSE
Can become pathological but often not a problem
How can anterior displaced disk cause locking in the TMJ?
The condyle cannot slide forward under the disk
T/F: TMJ disease is purely a mechanical problem.
FALSE
Inflammation and osteoarthrosis also play a role
What can be some consequences of reduced TMJ mobility?
- Reduced disk movement
- Reduced mandibular movement
- Poor synovial fluid circulation
- Ultimately declining joint health and function
What are the treatment options for TMJ disorders?
- Counseling
- Anti-inflammatory meds
- Occlusal orthotics
- Physical therapy
*Least invasive surgery if none of this works
What factors make a good treatment option for TMJ disorders?
- Research based
- Non-invasive
- Reversible
T/F: Occlusal orthotics for TMD should not alter jaw position or occlusion.
TRUE
