Impact Of Restorative Material On Fracture Strength Of Root Canal Treated Teeth: An In Vitro Study.

Background: There are several materials available in the market for the core buildup of endodontically treated teeth. The purpose of our study is to evaluate the fracture resistance of endodontically treated teeth restored with composite resin, amalgam and glass ionomer cement as core buildup materials.

Methods: Forty-eight sound-extracted mandibular premolar teeth were randomly divided into 4 groups of 12 teeth each.

Efficacy of Handpiece Mounted Continuous Irrigation System for the Removal of Residual Pulpal Debris During Root Canal Preparation.

Objective:  The removal of residual pulpal debris (RPD) from the root canal walls, especially in necrotic teeth is important for successful endodontic outcome. The aim of this study was to evaluate the RPD removal efficacy of handpiece mounted continuous irrigation with simultaneous root canal preparation from the apical third of root canals as compared to conventional syringe irrigation (SI).

Materials And Methods:  Ninety extracted teeth were randomly divided into three groups: SI; handpiece mounted continuous irrigation (CI); and both syringe and continuous irrigation (CI+SI).

Success rate of resin bonded restorative dentistry bridges.

Objective: To assess the success rate of resin bonded bridges.

Design: A descriptive cross-sectional study.

Place And Duration Of Study: Fatima Jinnah Dental College Hospital, Karachi between August 1998 and August 2002.
