Evaluation of single-use rotary nickel-titanium instruments.

The purpose of this study was to analyze the number and types of defects observed in single-use, rotary nickel-titanium instruments. Every ProFile Series 29.04 taper nickel-titanium instrument used during a 4-week period in an endodontic specialty practice was collected.

Non-surgical post perforation repair with mineral trioxide aggregate: a case report.

Mineral trioxide aggregate, or MTA, is a biocompatible material that has demonstrated numerous clinical applications in endodontics. It appears to be an improvement over other materials for use in procedures that involve root repair and bone healing, as it has consistently demonstrated the ability to promote regeneration of the original tissues when it is placed in contact with the periradicular tissues. This article describes the use of MTA for the successful non-surgical repair of an iatrogenic post perforation.

The influence of sodium hypochlorite irrigation on the accuracy of the Root ZX electronic apex locator.

The purpose of this in vitro investigation was to determine whether the presence of sodium hypochlorite influences the accuracy of the Root ZX electronic apex locator. Forty, extracted, human teeth were mounted in an experimental apparatus. After achieving ideal access, working length measurements were obtained using the Root ZX.
