In vitro evaluation of dentinal tubule penetration and biomineralization ability of a new root-end filling material.

Introduction: Capasio is being developed as a new generation of endodontic material with potential use as a root-end filling material. The aim of this study was to compare the ability of Capasio and mineral trioxide aggregate (MTA) to penetrate human dentinal tubules and examine the interaction of Capasio and MTA with a synthetic tissue fluid (STF) and root canal walls in extracted human teeth.

Methods: Root-end preparations were filled with Capasio or MTA, allowed to set for 4 weeks in STF, and then sectioned at 1, 2, and 3 mm from resected surface.

Usage parameters of nickel-titanium rotary instruments: a survey of endodontists in the United States.

Introduction: Usage of U.S. endodontists regarding rotary root canal instruments is not well-documented.
