An in vitro Evaluation of Fracture Resistance of endodontically treated Teeth with Different Restorative Materials.

Aims: The aim of the present study is to compare and assess the fracture resistance of root canal treated teeth with different restorative materials.

Materials And Methods: The present in vitro study was carried out on seventy-five freshly extracted, noncarious, single-canal human lower-first premolars with similar anatomic characteristics. Teeth were randomly assigned to five groups with 15 teeth being present in each group.

Evaluation of Two Facebow/Semi-adjustable Articulator Systems for Orienting Maxillary Cast on Articulators: A Pilot Study.

Aim: The present study was aimed to assess the transferability of occlusal plane (OP) orientation from the patient to the articulators with the help of two different facebow systems and evaluated with a gold standard.

Materials And Methods: Twenty dentate patients were selected for the study. Two semi-adjustable arcon articulators that are Hanau Wide(®) Vue using SpringBow and Whip Mix(®) using quick-mount facebow were used in the study.
