INTRODUCTION The aim of any root canal treatment is to achieve a canal free of micro organisms, residual pulp remnants, debris and smear layer for the long term success of the procedure. Manual and automated instrumentation techniques along with proper irrigation regime is used to arrive at the aforementioned goal. Many authors focused on the preparation capabilities of various manual and rotar...

INTRODUCTION This study analyzed the in vivo microbiological status of the root canal systems of mesial roots of mandibular molars with primary apical periodontitis after 1- or 2-visit endodontic treatment. METHODS Mesial root canals were instrumented by using either a combination of K3 and LightSpeed instruments (mesiobuccal canals) or the ProTaper system (mesiolingual canals), with 5% NaOCl...

Sodium hypochlorite (NaOCl) in various concentrations is the most widely used endodontic irrigant, but it can be an irritant to vital tissues. There are several reports about the complications of irrigation with NaOCl during root canal therapy. Most of the complications are the result of accidental extrusion of the solution from the apical foramen or accessory canals or perforations into the pe...

Thirty-four percent (34.40%) of irrigation areas in Indonesia are under the authority central government, 17.89% provincial government and 47.71% District/Municipality government. Various efforts have been made by to improve performance surface water systems that cover 78% total area, however, did not significantly. One cause is due damage national canals affect system. The purpose this study w...

Endodontic irrigation aims to clean and disinfect the root canal system. Passive ultrasonic irrigation (PUI) is based on the use of an ultrasound-activated instrument into the root canal filled with irrigant. The aim of this study was to evaluate, ex vivo, the effectiveness of PUI in eliminating Enterococcus faecalis from root canals. Seventy-five extracted human single-root teeth were used. Af...

BACKGROUND The aim of this study was to compare manual needle irrigation (MNI), RinsEndo (RE), and passive ultrasonic irrigation (PUI), and assess the effect of gravity on extrusion from the apex in vitro. MATERIAL AND METHODS The distobuccal roots of molars were used and the canals were instrumented up to F2. Teeth were mounted on models, which permitted visualization and manipulation of the...

Pakistan is home to one of the largest and most complex irrigation infrastructure systems in the world, consisting of 25 million hectares of irrigated agriculture, 56,000 kilometers of main canals, and tubewells in excess of 600,000. Nearly 100 million people depend on 107,000 water courses that are fed by 44 canal systems. Ineffective water management policies in the past have affected water a...

Introduction: This study aimed to evaluate and compare the apical sealing ability of different irrigation regimens (NaOCl, CHX, NS, and MTAD) . Methods: Seventy intact extracted single-rooted human teeth were selected. The roots were resected at 3 mm short of the apical foramen after access preparation. The canals were prepared with profile. This rotary file moved forward into the apical for...

to assess the effects of different final irrigants on the bond strength of bonded root filling materials, epiphany/resilon and epiphany self-etch (se)/resilon.the root canals of eighty single-rooted extracted human teeth were prepared. after the smear layer was removed using 17% edta, the samples were randomly divided into eight groups. in groups 1 and 2, no additional irrigant was used after e...
