Effect of F-File on removal of the smear layer: a scanning electron microscope study.

The aim of this study was to evaluate the effectiveness of F-File with NaOCl on removal of the smear layer. A total of 48 single-rooted teeth were instrumented using crown-down technique with one of the irrigation agents: distilled water, 5.25% NaOCl, RC-Prep, Glyde, MTAD or F-File with NaOCl.

The apical sealing ability of a new root canal filling material.

Purpose: To assess the apical sealing property of a new root canal filling material, Epiphany.

Methods: Seventy extracted maxillary and mandibular single-rooted teeth were used. They were randomly divided into three groups and obturated by lateral condensation with gutta-percha and AH 26/AH Plus sealers and Resilon core material and Epiphany sealer.

Coronal sealing ability of a new root canal filling material.

Background And Objective: To date, many different materials have been proposed for root canal fillings, but gutta-percha (used with various types of sealers) has remained the material of choice for over a century. A new root canal obturation system, the Epiphany endodontic obturation system, has been developed to replace gutta-percha and traditional sealers for root canal obturation. The purpose of this study was to evaluate the coronal sealing ability of the new endodontic obturation system.

Influence of immediate and delayed post space preparation on sealing ability of resilon.

Objective: The purpose of this study was to evaluate the effect of immediate and delayed post space preparation on the sealing ability of a new root canal filling material.

Study Design: Seventy-two extracted teeth were prepared and obturated with gutta-percha/AH-Plus and Resilon/Epiphany sealer by the lateral compaction technique. The teeth were divided randomly into 4 groups, and the post space was prepared either immediately after filling or after the obturated teeth had been stored in saline at 37 degrees C for a week.

A case of tularemia presenting as a dental abscess: case report.

Objective: The purpose of this report is to present a tularemia case accompanied by a neck mass that easily may be confounded with dental abscess.

Summary: Francisella tularensis is a potential agent of biologic terrorism. Thirty percent of the symptoms seen in tularemia localize in the head and neck region and are sometimes mistaken for complications of a dental abscess.

Apical leakage of Resilon obturation material.

Aim: The aim of this study was to assess the apical sealing ability of Resilon obturation material.

Methods And Materials: Forty-two single rooted extracted human teeth were selected and randomly divided into three groups. They were obturated using lateral condensation with gutta-percha and AH 26/AH plus and Resilon; also, 12 root canals were used as control groups.

Assessment of the sealing ability of a new root canal obturation material.

This study was designed to compare the leakage allowed by different obturation materials, using a fluid-transport method. Sixty-six single-rooted human anterior teeth were fully instrumented by using the "step-back" technique and irrigated with 5.25% sodium hypochlorite.

A technique for restoring an overflared root canal in an anterior tooth.

This article describes a technique for fabricating a dowel and core for a tooth with an overflared root canal. The technique involves supporting a glass fiber-reinforced prefabricated dowel with chopped silanated glass fibers.
