Since natural alternatives are needed in dentistry for the treatment of root canal, where standard irrigant is NaOCl with significant toxicity, aim study was to assess antibacterial properties non-chemical root-canal irrigants (aqueous extracts oregano, thyme, lemongrass, melaleuca and clove essential oils) against Enterococcus faecalis. For this, aqueous each oil (AqEO) were prepared. A soluti...

The present study aimed to evaluate the influence of the following irrigating solutions on the microhardness of root canal dentin: 2% sodium hypochlorite (2NaOCl), 5% sodium hypochlorite (5NaOCl), super-oxidized water (400 ppm Sterilox - Sx) and 17% EDTA (E). Eighty roots from bovine incisors were randomly divided into 8 groups (n=10): 2NaOCl, 5NaOCl, Sx, and 2NaOCl + E, 5NaOCl + E, Sx + E (ass...

The aim of this study was to evaluate the influence of two different irrigation protocols on artificial lateral root canal filling capacity using different obturation techniques. Sixty single-root human teeth were used. Two artificial lateral canals were created in the apical third. Root canals were instrumented up to a 45 K-file to the working length. Before each file, root canals were irrigat...

The fi rst and main goal of root canal treatment is the elimination of microorganisms from the contaminated root canal system and providing an environment for the healing of periapical tissues. Instrumentation alone cannoteffectivelyclean the complex root canal system. Souse of irrigantsalong mechanicalpreparationis required. But no single solution is able to fulfi ll these actions completely. ...

AIMS To investigate how the interfacial shear strength of the dentin-post interface with and without defects changes for different combinations irrigant/sealer. METHODS In forty human decoronated and instrumented teeth, fibreglass posts were inserted. The obtained root segments were randomly assigned to four different groups according to the irrigant adopted and the cement used to seal the ro...

Local debridement in the diseased pulp space is the main step in root canal treatment to prevent the tooth from being a source of infection. In this review article, requirements for irrigating solutions, chlorhexidine as an endodontic irrigant, its mechanism of action, characteristics like substansivity, adhering property to dentin and new formulations which are chlorhexidine based are spelled ...

BACKGROUND Endodontic microleakage or microfiltration refers to the percolation of fluids and micro-organisms at the interface of the obturation material and the walls of the root canal system. The aim of this in vitro study was to compare apical microfiltration of Resilon root canal filling by employing three different final irrigant solutions. MATERIAL AND METHODS 128 single-rooted teeth we...

Aim: The aim of this study was to evaluate the effectiveness of two instrumentation and irrigant techniques in smear-layer removal from root canals. Methodology: Thirty single-rooted teeth were randomly divided into two groups. Group 1 (continuous irrigation) was prepared using Selfadjusting file, and group 2 (manual irrigation; conventional needle irrigation) was prepared using with ProTaper f...

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...
