Question 194 · LDEK · Trauma to permanent teeth
Indicate the true statements concerning post-traumatic external inflammatory resorption:
1) the more immature the tooth is, the slower resorption is;
2) the more immature the tooth is, the faster resorption proceeds;
3) the course of the process is asymptomatic with pink discoloration of the tooth crown;
4) this process consists in resorption of root tissues and deposition of bone tissue in the places of resorptive sinuses;
5) during this process the toxins from the dentinal tubules diffuse to periodontium.
The correct answer is:
2) the more immature the tooth is, the faster resorption proceeds;
3) the course of the process is asymptomatic with pink discoloration of the tooth crown;
4) this process consists in resorption of root tissues and deposition of bone tissue in the places of resorptive sinuses;
5) during this process the toxins from the dentinal tubules diffuse to periodontium.
The correct answer is:
- A. 2,4.
- B. 2,5.
- C. 2,3,4.
- D. 1,3,4.
- E. 1,3,5.
Hint
Consider the role of the necrotic pulp, dentinal tubule width in young teeth, and how this differs from replacement and internal resorption.
