Effectiveness of different intracanal irrigation techniques in removing intracanal paste medicaments

By Dr. Barry H. Korzen | Posted May 26, 2014

In non-surgical multi-visit endodontic procedures the placement of medication for bacterial control and/or pain relief is a common treatment approach. But prior to obturation this medication must be removed so as not to interfere with the placement of the final obturation of the canal. Various irrigation techniques and different medications were studied. The authors found that the position of the irrigational needle and the type of medicament used are key factors which influence the effectiveness of irrigation in removing medicaments.

Effect of Photoactivated Disinfection on Bond Strength of Root Canal Filling

By Dr. Barry H. Korzen | Posted November 11, 2013

It is a basic tenet of endodontics that disinfection and obturation of the root canal system is essential for long-term success. Due to the anatomical complexity of that system instrumentation alone makes complete debridement of the microorganisms an impossibility. Photoactivated disinfection (PAD) uses the light of a specific wavelength to activate a photosensitizing dye in the presence of oxygen and has been successful in eliminating all cultivable bacteria from root canals.

Factors affecting irrigant extrusion during root canal irrigation: a systematic review

By Dr. Barry H. Korzen | Posted June 17, 2013

The aim of this study was to conduct a systematic review and critical analysis of published data on irrigant extrusion to identify factors causing, affecting or predisposing to irrigant extrusion during root canal irrigation of human mature permanent teeth.

Effect of Different Irrigation Protocols on Resin Sealer Bond Strength to Dentin

By Dr. Barry H. Korzen | Posted May 14, 2013

The aim of this study was to evaluate the influence of different irrigation protocols on resin-based sealer bond strength to dentin and the associated failure pattern. The experimental results found that irrigation protocols influenced the bond strength of resin sealers to dentin.
