Carrier-based root canal filling materials: a literature review.

A review of the literature on the use of carrier based obturation materials focusing on Thermafil and Resilon based obturator (RealSeal 1) are presented in this article. The review addressed the history, apical leakage, coronal leakage, biocompatibility, sealing ability and clinical success of Thermafil and RealSeal 1. Based on the studies gathered, this review concluded that both treatment techniques (Thermafil and RealSeal 1) did not provide excellent apical sealing ability.

The effect of root canal sealers and timing of cementation on the microlekage of the parapost luted with resin cement.

Objectives: The objectives of the study were to study the effect of root canal sealers either eugenol or non-eugenol and timing of cementation on microleakage of the parapost luted with resin cement.

Materials And Methods: Seventy extracted human, single-rooted teeth were instrumented using a crown-down technique. All teeth were instrumented up to a size 50 .

Fracture resistance of teeth obturated with RealSeal using two different chelating agents: an in vitro study.

Objectives: The aim of this study was to evaluate the fracture resistance of endodontically treated teeth filled with a resin-based obturation material using two different chelating agents.

Methods And Materials: Forty extracted single-canal human teeth were prepared, instrumented, and randomly divided into three groups: Group 1 (n=15) received a final flush with 10 ml of neutralized 17% EDTA, followed by 10 ml of sodium hypochlorite (NaOCl), then obturated using lateral condensation with RealSeal. Group 2 (n=15) received a final flush of BioPure MTAD, followed by 10 ml of NaOCl, then obturated using lateral condensation with RealSeal.
