Question 68 · LDEK · Functional disorders of the masticatory system
Indicate clinical signs and symptoms of temporomandibular joint articular disc displacement without reduction:
1) acute pain in temporomandibular joint region, problems in chewing food;
2) mandible deviation towards the affected temporomandibular joint during opening mandibular movement;
3) mandible deviation towards the healthy temporomandibular joint during opening mandibular movement;
4) limited range of opening mandibular movement, pain in the preauricular area;
5) extended range of protrusive mandibular movement and limited lateral mandibular movements.
The correct answer is:
2) mandible deviation towards the affected temporomandibular joint during opening mandibular movement;
3) mandible deviation towards the healthy temporomandibular joint during opening mandibular movement;
4) limited range of opening mandibular movement, pain in the preauricular area;
5) extended range of protrusive mandibular movement and limited lateral mandibular movements.
The correct answer is:
- A. 1,2.
- B. 2,5.
- C. 3,5.
- D. 1,2,4.
- E. 3,4,5.
