Comparison of Leakage in Endodontically Treated Teeth Obturated With Different Types of Gutta Percha Coatings and Bioceramic Sealer

In vitro study to compare the sealing ability of bioceramic-coated gutta-percha with bioceramic sealer against conventional gutta-percha with bioceramic sealer in root canal obturation. A total of 60 extracted human single-canal teeth will be prepared and obturated according to standardized protocols, then evaluated for microleakage. Data will be analyzed using SPSS (version 25) with appropriate non-parametric tests at a significance level of p\<0.05. The outcomes are expected to identify the more effective obturation material combination in achieving a fluid-tight seal, thereby contributing to improved success rates in endodontic therapy.
