Question 130 · LDEK · Biomechanics and tissue response to treatment
Indicate the true statements concerning the temporary increase in tooth mobility during orthodontic treatment:
1) usually leads to the loss of the affected tooth, even while maintaining perfect hygiene;
2) usually does not exceed the II or III degree of unstability;
3) first of all, the force acting on the tooth should be increased by raising the occlusion on the affected tooth with a composite material or glass-ionomer;
4) rarely, the cause of tooth pathological mobility may be tooth root resorption, especially in a replanted or ectopically erupted tooth;
5) each case of tooth pathological mobility should encourage radiological diagnostics.
The correct answer is:
2) usually does not exceed the II or III degree of unstability;
3) first of all, the force acting on the tooth should be increased by raising the occlusion on the affected tooth with a composite material or glass-ionomer;
4) rarely, the cause of tooth pathological mobility may be tooth root resorption, especially in a replanted or ectopically erupted tooth;
5) each case of tooth pathological mobility should encourage radiological diagnostics.
The correct answer is:
- A. 1,3,4.
- B. 2,3,4,5.
- C. 2,3,5.
- D. 2,4,5.
- E. 1,4,5.
Hint
Ask whether transient mobility is reversible, whether force on the tooth should be raised or reduced, and when X-rays are justified.
