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...

Irrigation is probably the most underrated procedure in Endodontic therapy. While most articles or presentations spend a great deal of time on shaping procedures, not much emphasis is given for irrigation. This has led to a great deal of confusion on the type of irrigant, the protocol and the method of use. The purpose of this article is to discuss root canal irrigants, irrigation techniques an...

The subcutaneous cervicofacial emphysema is a rare and serious disease. There is a wide variety of etiologic factors for subcutaneous cervicofacial emphysema. As an maitrisable factor, the use of hydrogen peroxide 3% as an irrigant to newly operated tissue plans may cause emphysema. We report here a case with iatrojenic cervicofacial emphysema, occurred after the irrigation of hydrogen peroxide...

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...

The case reports describes non surgical healing in periradicular lesions.A conservative approach with 5.25% sodium hypochlorite was used for irrigation, and calcium hydroxide was used for the intra-canal dressing and 2% chlorohexidine as a final irrigant. Periapical healing was observed 1 month after obturation and continued in the 12-month recall. This report confirms that the large size of a ...

INTRODUCTION Sodium hypochlorite (NaOCl) is an effective antimicrobial irrigant, however its toxic effects and deterrent odor are not ideal. Carvacrol is an edible plant extract with anti-inflammatory and anti-bacterial properties that is effective against Enterococcus (E) faecalis. The aim of this study was to evaluate Carvacrol's antibacterial efficacy against E. faecalis bacteria as a final ...

The present study evaluated the influence of 2% chlorhexidine and 2.5% sodium hypochlorite on the resin sealer/dentin interface bond strength of AH Plus/gutta-percha and Epiphany/Resilon. Seventy-two extracted bovine incisors were randomly distributed into 6 groups according to irrigant and sealers: G(S+AH)=physiologic saline solution+AH Plus/gutta-percha; G(S+Ep)=physiologic saline solution+Ep...

Chlorhexidine gluconate is a bisguanide germicide currently available with 70% isopropanol (Hibistat, Hibitane) or a detergent (Hibiclens, Hibiscrub) for preoperative skin preparation. As these solvents are toxic to the cornea, we investigated the safety and efficacy of aqueous chlorhexidine solutions for ophthalmic use. Chlorhexidine in Tris-glycine buffer was evaluated for retardation of epit...

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 The purpose of this study was to determine current trends in irrigation selection among endodontists. METHODS An invitation to participate in a web-based survey (QuestionPro) was e-mailed to 3844 members of the American Association of Endodontists. Survey participants were asked between 10 and 14 questions based on their individual responses. Among other questions, participants w...
