Question

The most appropriate method to prevent root canal

obstruction during the instrumentation phase of
endodontic treatment is to
A. obtain adequate access.
B. use a chelating agent.
C. irrigate copiously.
D. use reamers instead of files

Answer 1

The priority method to prevent root canal obstruction during endodontic treatment is to ensure adequate access, which allows instruments to reach and clean all areas effectively.

Step-by-step explanation:

The most appropriate method to prevent root canal obstruction during the instrumentation phase of endodontic treatment is to obtain adequate access. This step ensures that all areas of the root canal system are reachable and can be properly cleaned and shaped. Adequate irrigation should be performed to flush out debris, commonly using sodium hypochlorite or similar solutions. Although using a chelating agent, such as EDTA, can help to remove the smear layer and facilitate instrumentation, and copious irrigation is necessary; the priority is on appropriate access preparation. It allows the use of endodontic instruments, whether they are files or reamers, in the most efficient and safe manner.
