Question 24 · LDEK · Cysts of the jaws
Indicate the true statements concerning the development of the radicular cyst (RC):
1) size increase of the soft-tissue cyst in the bone structure is related to the prostaglandin synthesis by the cyst cells, which is responsible for bone resorption;
2) determinants of RC development initiation are bacterial exotoxins released by bacteria, activating the biochemical activity of EGFR;
3) theory of malnutrition states that the nutrition of epithelial bands proliferating in various directions becomes poorer and poorer;
4) in 85% of cases, the process of transition of the apical granuloma into the structures of cyst is a response to an infectious factor.
The correct answer is:
2) determinants of RC development initiation are bacterial exotoxins released by bacteria, activating the biochemical activity of EGFR;
3) theory of malnutrition states that the nutrition of epithelial bands proliferating in various directions becomes poorer and poorer;
4) in 85% of cases, the process of transition of the apical granuloma into the structures of cyst is a response to an infectious factor.

- A. only 1.
- B. 1,2,3.
- C. 2,4.
- D. 2,3,4.
- E. none of the above .
Hint
Consider how the cyst resorbs bone, what triggers proliferation of Malassez rests, the nutrition theory, and what share of periapical lesions are cysts.
