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.
None
Teeth with calcified (non-negotiable) canals.
Teeth with internal/external root resorption (as seen on radiograph)
Teeth with caries extending to the floor of pulp chamber.
Teeth with a single canal but open apex.
Parallel
bioceramic coated gutta percha
Procedure/SurgeryExperimental Arm (Bioceramic-coated GP + Bioceramic Sealer): Specimens will be obturated using bioceramic-coated gutta-percha cones in combination with bioceramic sealer after canal preparation with ProTaper NEXT files up to size F3.
conventional(non-coated) gutta percha
Procedure/SurgeryActive Comparator Arm (Conventional GP + Bioceramic Sealer): Specimens will be obturated using conventional (non-coated) gutta-percha cones in combination with the same bioceramic sealer after canal preparation with ProTaper NEXT files up to size F3.
post obturation leakage
assessment of leakage in obturated teeth in experimental group and control group via dye penetration method. specimens soaked in 1% methylene blue dye for seven days
