Clinical success of endodontically treated posterior teeth is determined by the postendodontic restoration. Several options have been proposed to restore endodontically treated teeth. Endocrowns represent a conservative and esthetic restorative alternative to full coverage crowns. The preparation consists of a circular equigingival butt-joint margin and central retention cavity into the entire pulp chamber constructing both the crown and the core as a single unit. The case reports discussed here are moderately damaged endodontically treated molars restored using all ceramic endocrowns fabricated using two different systems, namely, CAD/CAM and pressed ceramic.

Aim:To compare the vertical root fracture resistance of endo dontically treated teeth obturated using different obturating materials. Materials and methods:Decoronated roots of 75 single canal lower second premolar teeth were divided randomly into 5 groups. The first group (Group I) served as a negative control. The remaining four Groups were cleaned and shaped using ProTaper Endodontic rotary files and obturated with guttapercha + TubliSeal EWT sealer (Group II), ThermaFil + AH Plus sealer (Group III), RealSeal + RealSeal sealer (Group IV) and GuttaFlow obturating system (Group V). The roots were then embedded in acrylic resin blocks and subjected to vertical load until fracture with a spreader in a universal testing machine and the forces were recorded.Results: Fracture resistance of group I > group IV > group V > group III > group II, which were statistically significant. Conclusion:Obturation of roots with resin based obturation material-RealSeal had increased VRF resistance compared to the guttapercha obturation systems.Clinical significance: Obturation of the root canals with resin based obturation system-Resilon reinforces the fracture resistance of endodontically treated teeth and contributes to the overall success of the endodontic treatment.
