INTRODUCTION Sodium hypochlorite (NaOCl) has long been the most preferred root canal irrigant in endodontic treatment, but besides being an effective anti-microbial agent, it is highly cytotoxic. Thus, a search for an alternative herbal irrigant which would be more biocompatible but equally effective led to this study. AIM To assess the anti-microbial efficacy of garlic extract (GE) against E...

Aim : To assess the cleaning efficacy of manual and automated instrumentation using 4% sodium hypochlorite singly and in combination with Glyde file Prep as root canal irrigant. Methodology : The study utilized 40 extracted human permanent premolars with single, straight and fully formed root. The teeth were then divided into four groups of ten each, Group I and II were prepared by manual instr...

BACKGROUND Sodium hypochlorite (NaOCl) is the most widely used endodontic irrigant because of its excellent antimicrobial, organic tissue dissolving, and lubricating properties. However, it is highly cytotoxic to the periapical tissues. AIM This study evaluated in vitro the extrusion of 5.25% NaOCl through the apical foramina of mesiobuccal (MB) root canals of maxillary first molars in two ex...

INTRODUCTION The aim of this study was to compare the outcome of a root canal treatment with and without additional ultrasonic activation of the irrigant. METHODS Single-rooted teeth with radiographic evidence of periapical bone loss were randomly assigned to 2 treatment groups. In both groups syringe irrigation was performed, and in one group the irrigant was also activated by ultrasound. Te...

introduction: the aim of this study was to compare the antibacterial effect of persian green tea extract (gte) and 2.5% sodium hypochlorite (naocl) against enterococcus faecalis ( e. faecalis ) as an intracanal irrigant. methods and materials: thirty freshly extracted teeth were instrumented and sectioned into mesial and distal segments. the specimens were put into wells containing 2 ml of e. f...

A mandibular second premolar with four canals is an interesting example of anatomic variations. This report describes a case of a mandibular second premolar with three roots and four canals (one mesiobuccal, two distobuccal and one lingual). The canals were prepared using K-files and irrigated with NaOCl (5.25%) and normal saline as the final irrigant. The canals were filled laterally with gutt...
