SUCCESS RATE OF OVERFILLED ROOT CANAL TREATMENT
Abstract
Background: Traditionally, poor obturation has been considered the primary cause of root canal treatment failures The purpose of this study was to assess the success rate of overfilled root canal treatment cases in order to decide whether a definitive restoration can be placed immediately following treatment in an overfilled case or whether the patient needs to be kept on a follow up prior to the placement of a definitive restoration. Methods: A total of 1242 patient’s periapical radiographs (1748 teeth) were assessed, out of which 397 teeth (in 285 patients) were found to be overfilled. Out of these 285 patients, 111 (128 cases) agreed to participate in this cross sectional study and were recalled for clinical and radiographic examination. Success was evaluated clinically by absence of symptoms (pain, swelling, tenderness to percussion and sinus tract) and radiograhically by the decrease in size of periapical lesion or no change in size. Increase in size of periapical lesion was deemed to be a failure. Results: Our findings revealed that despite overfill, the treatment was successful in 115 cases and failure was noted in 13 cases showing an overall success rate of 89.8% and failure rate of 10.2%. Out of 13 cases of failure, all 13 showed an increase in periapical lesion size, out of which 10 were accompanied with pain. Conclusion: Based on the results obtained in our study, we have determined that there is no need to delay placement of a permanent restoration on overfilled teeth (ruling out the presence of other procedural errors) nor is there any need to pursue any further surgical or non-surgical endodontic treatment. However we would suggest that patients should be kept on follow-up after placement of permanent restoration.References
