What is the primary indication for periradicular surgery in endodontics?

Accepted Answer

Failure of non-surgical treatment with persistent periradicular pathology

Answer

Periradicular surgery is indicated when non-surgical retreatment has failed or is not feasible and periradicular pathology persists.

Question 2

Which flap design provides the best access and healing for anterior teeth in endodontic surgery?

Accepted Answer

Full mucoperiosteal flap with vertical releasing incisions

Answer

A full mucoperiosteal flap with vertical releasing incisions provides optimal access and allows primary closure with good vascular supply.

Question 3

What is the recommended minimum depth for a root-end preparation during apicoectomy?

Accepted Answer

3 mm

Answer

A 3 mm root-end preparation depth is recommended to ensure adequate seal and removal of accessory canals in the apical delta.

Question 4

Which material is currently considered the gold standard for root-end filling in endodontic surgery?

Accepted Answer

Mineral Trioxide Aggregate (MTA)

Answer

MTA is the gold standard root-end filling material due to its superior biocompatibility, sealing ability, and capacity to set in the presence of moisture.

Question 5

At what angle should the root resection be made during modern endodontic microsurgery?

Accepted Answer

As perpendicular (0–10 degrees) to the long axis as possible

Answer

The root resection should be as perpendicular to the long axis as possible to minimize exposed dentinal tubules and reduce microleakage.
