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...

introduction: a desirable characteristic of root canal irrigants is the ability of dissolving soft tissues. sodium hypochlorite, an antibacterial and tissue solvent irrigant used in endodontic treatment is known to be toxic for periapical tissues. chlorhexidine gluconate, an effective antimicrobial agent, is another irrigant with limited tissue dissolving ability. a mixture of a tetracycline is...

Aim: To compare the effect of QMix, a mixture of tetracycline, citric acid, and detergent (MTAD), and ethylenediaminetetracetic acid (EDTA) on the microhardness of the root canal dentin. Materials and methods: A total of 30 single-rooted teeth were decoronated at 15 mm from the root apex. Root canal instrumentation using step back technique was done and the specimens were split into two halves ...

INTRODUCTION This in vitro study aimed to investigate the antibacterial effects of photodynamic therapy (PDT) with methylene blue (MB) or toluidine blue (TB) (both at 15 microg/mL) as a supplement to instrumentation/irrigation of root canals experimentally contaminated with Enterococcus faecalis. METHODS Seventy extracted teeth had their root canals contaminated with an endodontic strain of E...

OBJECTIVES The aim of this study was to compare the cleaning efficacy of different final irrigation regimens in canal and isthmus of mandibular molars, and to evaluate the influence of related variables on cleaning efficacy of the irrigation systems. MATERIALS AND METHODS Mesial root canals from 60 mandibular molars were prepared and divided into 4 experimental groups according to the final i...

This clinical study was conducted to assess the bacterial reduction after chemomechanical preparation with 2.5% NaOCl as an irrigant and the additive antibacterial effect of intracanal dressing with calcium hydroxide. According to stringent inclusion criteria, 11 teeth with primary intraradicular infections and chronic apical periodontitis were selected and monitored in the study. Bacterial sam...

The purpose of this study was to determine whether chlorhexidine gluconate (0.12%), used as an endodontic irrigating solution, would affect the apical seal of three root canal cements. One hundred, extracted, human, single-canal teeth were divided into 9 experimental groups of 10 teeth each, in addition to a positive and negative control group of 5 teeth each. The teeth were decoronated at the ...

The main objective of endodontic treatment is the total removal any necrotic tissues and microorganisms along with their byproducts found within infected root canal to treat prevent recolonization these micrbad oorganisms. To date, no known irrigant has a 100% elimination rate on microorganisms, many combinations irrigates have been suggested, care must be taken mixing interaction side effects....

INTRODUCTION Effective irrigant delivery and agitation are prerequisites for successful endodontic treatment. Ultrasonic irrigation can be performed with or without simultaneous ultrasonic instrumentation. Existing literature reveals that ultrasonic irrigation may have a very positive effect on chemical, biological and physical debridement of the root canal system as investigated in many in vit...

This study aimed to evaluate the effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin. Sixty root canals from mandibular incisors were instrumented and randomly divided into six groups (n = 10) according to the irrigant used: QMiX, 17% EDTA, 10% citric acid (CA), 1% peracetic acid (PA), 2.5% NaOCl (solution control), and distilled water (negative cont...
