Passive vs Sonic Assisted Irrigation–Effect on Smear Layer

The ultimate goal of endodontics is to eliminate the bacterial bio-load in the complex root canal system, especially in the critical apical one-third. We achieve this objective by a combination of instrument-based mechanical preparation and chemical irrigation of the prepared root canal system.
Sodium hypochlorite (NaOCl), at a concentration of 3% …

Apexification With MTA

When teeth with immature roots suffer pulpal necrosis, the formation of dentin stops and root development ceases. As a result, the canals remain wide with thin dentin walls and a large apical opening. Often, the root canal system has an inverse architecture with the apical diameter significantly wider than the coronal diameter.This blunderbuss shape …

Outcome Comparisons between Implants and Endodontically Treated Teeth

Implants and endodontics are both highly predictable procedures. It is difficult, however, to make objective comparisons between the procedures because the factors associated with success and failures are different. For example, the majority of endodontic outcome studies use complete bony healing and absence of symptoms as their criteria for success, while implant success is often …

Resin Root Canal Fillings: Fact or Fiction

In 2005, the first new, non-gutta percha (GP) root filling material in 50 years was launched. The manufacturers of Resilon, a synthetic resin root filling material, claimed to have significantly better sealing ability than gutta percha. The concept behind Resilon was the desirability of bonding the resin point to a resin sealer, which in turn …
