The common preoperative causes of endodontic treatment failure include all of the following except which one?
Correct Answer: Leaking coronal restoration
Description: Failure of previous endodontic therapy can be attributed to various factors, such as procedural errors, missed canals, or persistent periapical pathosis. Knowledge of the cause of failure is pertinent to the treatment of these cases because it allows the cause to be adequately rectified.
Misdiagnosis, poor case selection and error in treatment planning are the preoperative causes and leaking coronal restoration is the postoperative cause of endodontic therapy failure.
