Background: This study was conducted for a Comparative Evaluation of Five Obturation Techniques in the Management of Simulated Internal Resorptive Cavities. Material and methods: Fifty human maxillary central incisors with fully developed root apices that had just been extracted were gathered. For this study, teeth without internal resorption, calcification, or a root canal filling were selected. The roughly 21 mm teeth that were found were cleaned with ultrasonic technology to remove calculus and debris. They were then stored in a saline solution. A size 10 K-file was inserted into each tooth's prepared endodontic access to locate the apical foramen. After the teeth were instrumented using a master apical file size 40 and the step-back procedure up to size 80, they were finally irrigated with saline and 2.5% sodium hypochlorite solution. SPSS software was used for statistical analysis.
