INTRODUCTION Effective durable adhesion between post material and dentine using resin cements is essential for longevity of restoration. The aim of this in vitro study was to compare the effect of different irrigants on smear layer removal after post space preparation. METHODS AND MATERIALS A total of 75 extracted anterior human teeth were selected. The canals were instrumented by rotary syst...

UNLABELLED Nitric oxide (NO) has been considered a key molecule in inflammation. OBJECTIVE The aim of this study was to evaluate the effect of treatment with L-NAME and sodium nitroprussiate, substances that inhibit and release NO, respectively, on tissue tolerance to endodontic irrigants. MATERIAL AND METHODS The vital dye exudation method was used in a rat subcutaneous tissue model. Injec...

We previously reported that the in vitro antimicrobial activity of a 2.0% chlorhexidine endodontic irrigant was equivalent to that of 5.25% sodium hypochlorite. The purpose of this study was to determine if chlorhexidine irrigants could instill substantive antimicrobial activity in instrumented root canals in vitro. Human teeth were instrumented using 2.0% or 0.12% chlorhexidine as irrigants. A...

Root canal irrigants play an important role in the success of root canal treatment. As the major objective in root canal treatment is to disinfect the entire root canal system, it requires that the pulpal contents be eliminated as sources of infection. This goal may be accomplished using mechanical instrumentation and chemical irrigation, in conjunction with medication of the root canal between...

• Fluorescence readings of E. faecalis infected human dentine sections were quenched when treated with oxidizing irrigants. returned to baseline in 24 h. The fluorescence quenching effects agents need be considered using laser as a diagnostic tool assessing the quality root canal debridement or disinfection. This study aimed assess changes characteristics Enterococcus over period h following tr...

Use of an appropriate root canal irrigant is essential during endodontic treatment, due to the complex and unpredictable anatomy of the root canal system and limitations in the mechanical instrumentation techniques used to obtain a clean, bacteria-free canal. Several irrigants, such as sodium hypochlorite, chlorhexidine, hydrogen peroxide, and normal saline, have been proposed as canal system i...

AIM This study was conducted to evaluate the antimicrobial activity of 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) and BioPure MTAD when used as a fnal rinse against Enterococcus faecalis. MATERIALS AND METHODS Sixty single-rooted premolars were biomechanically prepared, inoculated with E. faecalis and divided into various groups. These were then irrigated with the test irrigant...

Endodontic emergencies are associated with pain and swelling which requires immediate diagnosis and treatment. The main causative factors for these emergencies are pulp and peri-radicular pathosis, traumatic injuries, procedural complications; were sodium hypochlorite accidents can occur. The impetus behind a successful root canal treatment relies on a thorough debridement of tissue remnants, b...
