Comparative evaluation of incorporation of ferrule in premolars endocrown designs to check any alterations in their fracture resistance: A pilot study.

Introduction: Endocrown preparation of endodontically treated teeth as final restoration has been extensively studied for different teeth. Bindl . questioned the application of endocrowns for premolars due to the pulp chamber space's smaller dimensions, which diminish bonding surface area.

Comparison of Fracture Resistance of Two Resin-based Sealers to Root Canal Walls: An Study.

Aim And Objective: In the present study, the prepared roots obturated by gutta-percha/AH plus and Resilon/Epiphany were tested and compared for fracture resistance. The study also does a scanning electron microscope (SEM) evaluation of the adaptability of these obturating materials to root canal walls.

Materials And Methods: One hundred extracted mandibular premolars were decoronated and the dimensions of the roots were standardized.
