Comparison of the Fracture Resistance of Endodontically Treated Maxillary Incisors Restored with Six Different Post and Core Systems

Background and Aim: Different methods and materials are available for post and core (P&C) fabrication. We aimed to compare the fracture resistance and failure modes of endodontically treated maxillary central incisors restored with six different P&C systems. Materials and Methods: In this in-vitro study, after endodontic treatment and coronal preparation of 60 maxillary central incisors, six d...

Evaluation of Physical Properties of Different Core Build- up Materials

Fracture resistance of roots obturated with three different materials.

OBJECTIVE The aim of this study was to compare the fracture resistance of roots obturated with different materials. STUDY DESIGN Sixty root canals were instrumented and divided into 4 equal groups (n = 15 each). The root canals in group 1 were filled with AH26 sealer and gutta-percha, in group 2 with Resilon and Epiphany, and in group 3 with Ketac-Endo Aplicap and gutta-percha. Fifteen root c...

evaluation of retention of two different cast post-core systems and fracture resistance of the restored teeth

statement of the problem: the survival of pulpless teeth restored with different post and core systems is still a controversial issue. purpose: this study compared the retention of two different post and core systems and also the fracture resistance of teeth restored with these systems. material and method: eighty endodontically treated maxillary central incisors were sectioned perpendicular to...
