The role of obturation in root canal treatment, although considered secondary to debridement and disinfection, still remains a critical stage for a successful outcome. The aim of obturation is to seal the periradicular tissues from the residual microorganisms left in the root canal system after chemomechanical debridement. Obturation of the root canal space has been performed using various tech...

INTRODUCTION This systematic review aimed to compare the effectiveness of sodium hypochlorite and chlorhexidine for root canal disinfection during root canal therapy. METHODS A literature search for clinical trials was made on the PubMed (MEDLINE), Web of Knowledge, SCOPUS, and Science Direct databases and in the reference lists of the identified articles up to January 2015. Quality assessmen...

Microbiota are found in highly organized and complex entities, known as biofilms, the characteristics of which are fundamentally different from microbes in planktonic suspensions. Root canal infections are biofilm mediated. The complexity and variability of the root canal system, together with the multi-species nature of biofilms, make disinfection of this system extremely challenging. Microbia...

Eradication of microbes from root canals and impeding of further reinfection is the basic support of endodontic treatment. This is achieved by overall disinfection and shaping of canals which can then be filled using a three-dimensional filling with a fluid-tight seal. To achieve these goals, the clinician must have integral knowledge of regular anatomy and anatomic variants of root canals. One...

The successful outcome of root canal therapy is related to the ability to negotiate the canal to its apical terminus, allowing thorough debridement, disinfection, and obturation of the prepared canal space. In situations in which calcific deposits have blocked access to the canal, treatment efforts are often thwarted. This article describes endodontic management of tooth with calcific metamorph...

OBJECTIVE The study was designed to test application of ultraviolet light to root canal walls, as a mean of complementary immediate disinfection after the use of sodium hypochlorite. STUDY DESIGN Root canals were infected ex vivo with Enterococcus faecalis for 48 hours. Non-attached bacteria were washed away, and the remaining attached bacteria were subjected to disinfection, with 5% sodium h...

Effective irrigant delivery and agitation are prerequisites to promote root canal disinfection and debris removal and improve successful endodontic treatment. This paper presents an overview of the currently available technologies to improve the cleaning of the endodontic space and their debridement efficacy. A PubMed electronic search was conducted with appropriate key words to identify the re...

INTRODUCTION This study set out to compare the efficacy of laser-activated and ultrasonically activated root canal disinfection with conventional irrigation, specifically its ability to remove bacterial film formed on root canal walls. METHODS Seventy human premolars were shaped to an apical size #20, taper .07, sterilized, and contaminated in situ with oral bacteria for 1 week and incubated ...
