Test on Veterinary Endodontic Complications and Management

Question 1: Ledging is an iatrogenic complication that can occur during the preparation and shaping of the root canal.

A. Ano

B. Ne

Explanation: The study materials list ledging under 'mistakes in preparation and shaping of the root canal', which is categorized as an iatrogenic complication.

Question 2: When performing root canal treatment on wide canals, lateral condensation is the recommended obturation method to avoid the risk of root fracture.

A. Ano

B. Ne

Explanation: The study materials state that there is a risk of root fracture when using lateral condensation in wide canals, and an alternative obturation method should be used instead.

Question 3: According to the study materials, what are the recommended treatment methods for narrow/stenotic canals?

A. Use path finders

B. Perform apicectomy and retrograde filling

C. Clean and shape carefully, then fill with CaOH2 or MTA

D. Try to file around the obstruction

Explanation: The study materials state that for narrow/stenotic canals, the recommended treatments are to 'use path finders or do apicectomy and retrograde filling'. The other options are treatments for different complications: cleaning and shaping with CaOH2 or MTA is for root fracture in the apical third, and filing around an obstruction is for pulp stones.

Question 4: According to the study materials, what are the recommended treatment options for a root fracture?

A. Clean and shape carefully, fill with CaOH2 or MTA, and splint the tooth if the fracture is in the apical third.

B. Perform hemisection of the fractured root in multirooted teeth.

C. Bypass the fractured area with a longer file and continue standard obturation.

D. Perform an apicectomy and retrograde filling, regardless of fracture location.

Explanation: For a root fracture in the apical third, the recommended treatment is to clean and shape carefully, fill with CaOH2 or MTA, and splint the tooth. In multirooted teeth, hemisection of the fractured root is suggested. These are directly stated in the 'root fracture' section of the anatomical problems.

Question 5: The primary management for instrument separation involves immediate removal of the broken part followed by an apicectomy if the fragment is at the apex.

A. Ano

B. Ne

Explanation: The study materials state that management for instrument separation includes filing around the broken part to bypass it (if not at the apex) and radiographic monitoring. While removal and apicectomy are mentioned as ways of removal, they are not presented as the primary management strategy in all cases, nor is an apicectomy specifically indicated immediately if the fragment is at the apex as the primary approach.
