ACUTE TMD:
1. Onset:
2. Locking:
3. Is Jaw Open and cannot close?
4. length? frequency?
5. Malocclusion?
6. Acute sudden malocclusion- diagnoses?

Answer 1

1. Onset: Pain is present < 3 months
2. Locking: Is jaw Closed & cannot open?
3. Is Jaw Open and cannot close?
4. How many seconds, minutes, hours, or days for locking? Frequency?
5. Malocclusion: was it gradual or sudden? Date first noticed & activity caused it.
6. Acute sudden malocclusion- diagnoses myospasm, myositis, fracture, tumor

Question 2

CHRONIC:
1. Onset:
◦ Ask pt if they have had? if yes?
◦ 2. Jaw locking?
◦ 3. Gradual Malocclusion? likely?

Answer 2

CHRONIC:
1. Onset: Pain is present > 3 months
◦ Ask pt if they have had this pain before.
If YES ask when it began
◦ 2. Jaw locking > 3 months
◦ 3. Gradual Malocclusion > 3 months:
likely arthritis or osteochondma

Question 3

stabilization splints and nightgaurds as tx’sin osteolysis

Answer 3

◦ Stabilization Splint worn for 6 months (to determine if condylar lysis has stabilized by checking occlusal contacts on splint prior to restorative treatment.
◦ Check monthly to see if occlusion is stable on nightguard.

often used with osteolysis cases to determine stability/progression

Question 4

RA signs:
* symmetry?
* joints
* morning stiffness ?
* hands?
* systemic?

Answer 4

• symmetric joints involved
• joint inflammation
• morning stiffness longer than 1hr
• spindle swelling of PIP and volar subluxation MCP
• systemic manifestations (fatigue)

Question 11

anterior disc displacement with reduction criteria

Answer 11

• click on open/close
• corrected deviation of mandible to affected side with open/close
• MRI reveals ant displaced disc with reduction upon opening

Question 12

anterior disc displacement without reduction criteria

Answer 12

• limited opening (assisted) <35 mm
• deflection of mandible to affected side
• MRI would reveal ant displaced disc which does not reduce with opening
