What is the primary indication for periradicular surgery in endodontics?
Answer: Failure of non-surgical treatment with persistent periradicular pathology
Periradicular surgery is indicated when non-surgical retreatment has failed or is not feasible and periradicular pathology persists.
Which flap design provides the best access and healing for anterior teeth in endodontic surgery?
Answer: Full mucoperiosteal flap with vertical releasing incisions
A full mucoperiosteal flap with vertical releasing incisions provides optimal access and allows primary closure with good vascular supply.
What is the recommended minimum depth for a root-end preparation during apicoectomy?
Answer: 3 mm
A 3 mm root-end preparation depth is recommended to ensure adequate seal and removal of accessory canals in the apical delta.
Which material is currently considered the gold standard for root-end filling in endodontic surgery?
Answer: Mineral Trioxide Aggregate (MTA)
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.
At what angle should the root resection be made during modern endodontic microsurgery?
Answer: As perpendicular (0–10 degrees) to the long axis as possible
The root resection should be as perpendicular to the long axis as possible to minimize exposed dentinal tubules and reduce microleakage.
Which magnification system is the standard of care in endodontic microsurgery?
Answer: Operating microscope at 10–25×
The operating microscope at 10–25× magnification is the standard of care, providing co-axial illumination and high magnification for precise root-end management.
