Drs. Tony Tataro and Mohammad Sabeti discuss and illustrate an alternative treatment Introduction The Hertwig epithelial root sheath (HERS) and the apical papilla interact epithelially and mesenchymally to mediate the root formation process.1 As stem cells move and develop into odontoblasts and fibroblasts, the pulp-dentin complex is generated at the expense of the apical papilla, […]

Dr. Eshwar Arasu discusses approaches to activating irrigants for effective endodontic treatment The chemomechanical preparation of the root canal system represents the most important phase of orthograde endodontic treatment. Reliance strictly on mechanical canal opening and fluid chemistry may be insufficient in achieving successful long-term endodontic outcomes. This article was written to review the clinical

Dr. L. Stephen Buchanan discusses a new concept in endodontic irrigation Endodontic irrigation is the most important part of root canal therapy (RCT), but I confess it has never been the most interesting part of the process for me because there is so little to see going on during irrigation. All the other aspects of

Dr. Gregori M. Kurtzman continues his discussion of coronal leakage prevention Introduction As discussed in part 1, coronal leakage is a frequent cause of endodontic failure related to salivary bacteria percolating between the coronal aspect of the tooth, down the obturated canals to lead to apical reinfection. This can be prevented by how the tooth
