Anaesthesia during retreatment: limits of evidence for direct causation

Hello, Doctor. I did not understand how using anaesthesia during retreatment causes pain on percussion.

Translated version of the Turkish original

With anaesthesia, the patient feels nothing during the procedure, and the risk of extruding gutta-percha and solution beyond the apex increases. Without anaesthesia, stopping as soon as the patient feels pain, slowing the motor and irrigating more carefully can reduce the risk of postoperative pain.
