OBJECTIVE To evaluate and compare the antimicrobial efficacy of 6% Morinda citrifolia, Azadirachta indica, and 3% sodium hypochlorite (NaOCl) as root canal irrigants. MATERIALS AND METHODS Thirty nonvital maxillary anteriors were randomly assigned to one of the three groups corresponding to the irrigant to be tested; 6% Morinda citrifolia juice (MCJ) (n = 10), A. indica (n = 10) and 3% NaOCl ...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of various irrigants on the push-out bond strength of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA). METHODS AND MATERIALS A total of 140 dentin disks with a thickness of 1.5±0.2 mm and lumen size of 1.3 mm, were randomly divided into 12 groups (n=10) and 4 control groups (n=5). The lumen of di...

OBJECTIVES To evaluate the accuracy of the Root ZX in teeth with simulated root perforation in the presence of gel or liquid type endodontic irrigants, such as saline, 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine liquid, 2% chlorhexidine gel, and RC-Prep, and also to determine the electrical conductivities of these endodontic irrigants. MATERIALS AND METHODS A root perforation was simu...

AIM To evaluate the relative antimicrobial efficacy of five different commonly used antimicrobial agents with regard to reduction in the number of Enterococcus faecalis and Escherichia coli as compared to normal saline. An agar disk diffusion in vitro method was used to test the efficacy of the root canal irrigants against these two microorganisms. The root canal irrigants used were: 5.25% sodi...

Irrigation has been performed in conjunction with endodontic therapy for many years. One of the primary reasons for irrigating the root canal system is to ensure cleanliness of the canals prior to obturation. This cleanliness involves both elimination of microorganisms and removal of organic matter. Sodium hypochlorite [NaOCl] is the most commonly used solution in root canal treatments, despite...

Amongst the bacterial species which most often cause endodontic failures, Enterococcus faecalis is the most important. This study compared the effectiveness of sodium hypochlorite and two new generation antibiotic-based endodontic irrigants, Tetraclean and MTAD. By means of an in vitro agar dilution assay, we show that both Tetraclean and MTAD are 100% effective against 54 clinical isolates at ...

Introduction: Historically, countless compounds in aqueous solution have been suggested as root canal irrigants. MTAD shows promise as an endodontic irrigant but there are very few studies comparing its antimicrobial effectiveness with NaOCl and Chlorhexidine. Objectives: To compare the antibacterial efficiency of MTAD, 2.5% Sodium Hypochlorite and 2% Chlorhexidine root canal irrigants against ...

Context Local administration of antimicrobial agents offer a "site-specific" approach to the periodontal therapy and it has several benefits. Aim The present study was aimed to assess the clinical and microbial changes by subgingival irrigation using different subgingival irrigants in periodontitis patients and also to assess the mechanical effect of different local irrigation devices; if any...

AIM To determine the antimicrobial effect of water extracts of leaves of Annona muricata and Simarouba glauca on Enterococcus faecalis using agar diffusion method. MATERIALS AND METHODS Dried leaves of A. muricata and S. glauca were powdered and extracted in a soxhlet apparatus. Enterococcus faecalis was grown overnight in Trypticase soy agar plates. About 10 μl of each extract was placed on ...

The aim of this study was to compare the efficacy of a new generation endodontic irrigant, Tetraclean, to the widely used sodium hypochlorite. Tetraclean combines a powerful detergent effect with a strong antimicrobial efficacy, whereas sodium hypochlorite has several drawbacks and is sometimes ineffective in preventing microbial-mediated endodontic failure. The bactericidal activity of both ir...
