Evaluation of Factors Responsible for Failure of Root Canal Treatment in an Adult Indian Population:A Cross Sectional Study

The ischolar_main canal treatment failure is a frequentproblem occurring in dentistry. Inadequate chemo mechanicalpreparation, poor obturation, over obturation, persistence of bacteria, instrument separation, missing canal,coronal microleakage are some of the causes responsible for the failure of the ischolar_main canal treatment. 400 ischolar_main canal treated teeth with failure were included in this study and were recorded using digital radiography. Under obturation was the predominant factor for the failure of ischolar_main canal treatment. The larger number of the endodontic failures was found in the timeperiod of within 4-5 years. The maximum average time period causing failure was seen to be 3.85 yearsfor over obturation..
