ABSTRACT Objective The aim of this study was to evaluate the loss of tooth structure after the removal of temporary restorative materials between endodontic treatment sessions performed by undergraduate students. Methods Twenty human molar teeth underwent endodontic coronal access and were randomly divided into two groups.

Dynamic Capacity and Surface Fatigue Life for Spur and Helical Gears [PDF]
A mathematical model for surface fatigue life of gear, pinion, or entire meshing gear train is given. The theory is based on a previous statistical approach for rolling-element bearings. Equations are presented which give the dynamic capacity of the gear

Abstract Hydrogen peroxide (HP) at 35% is effective for dental bleaching but may reduce enamel mineral content and induce structural changes. This study developed a bleaching‐hydrogel containing 6%HP and manganese‐oxide–doped Biosilicate (MnO_BioS), activated by violet LED, under in situ conditions.
