Computed TomographyEvaluationof Root Canal Desobturation of Lower Human Incisors
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 8
Abstract
Introduction: The purpose of endodontic treatment is cleaning and shaping the root canal system, but despite the technological advances, failures can occur. On this, non-surgical endodontic retreatment is the first option for solving the problem. Materials and methods: Twenty human mandibular incisors were instrumented with the Pro Design S system up to instrument 25.06 and filled with AHPlus (Dentisply / Maillefer, Ballaigues, Switzerland) cement using the single cone technique. The teeth were divided into two groups (n = 10) according to the instrument used for the retreatment. Group 1: Pro Design S 25.08 (PDS) and group 2: Reciproc 25.08 (REC). A master in endodontics prepared the teeth. The analysis of the remaining filling material was made by cone beam computed tomography(CBCT).Results:Student's t-test was used for comparison between groups. The two groups efficiently removed the obturator material, and there was no statistical difference between the groups (P> 0.05). Conclusion: Although it is a consensus in the literature that no technique is able to completely remove the obturator material from the canal system, in this study it was possible to observe in some samples the absence of material in the final tomography
