This study investigated the antibiofilm and antibacterial effects of farnesol and xylitol in a series of experiments in order to evaluate their potential use as root canal irrigants. The following substances were tested: 0.2% farnesol; 5% and 20% xylitol; 0.2% farnesol plus 20% xylitol; and saline (control). For comparison with an established endodontic irrigant, 2.5% NaOCl was included in each...

background and aims. during root canal preparation, debris extruded beyond the apical foramen may result in periapical inflammation and postoperative pain. to date no root canal preparation method has been developed that extrudes no periapical debris. the purpose of this study was to identify a system leading to minimal extrusion of debris from the apical foramen. the study was conducted to com...

objective: biopure® mtad (dentsply tulsa dental, usa) has been developed as a final irrigant following root canal shaping to remove intracanal smear layer. many of the unique properties of mtad potentially transfer to the conditioning process of tooth roots during periodontal therapy. the aim of this ex vivo study was to evaluate the effect of mtad on the removal of smear layer from root surfac...

AIM To introduce a new concept, the self-adjusting file (SAF), and discuss its unique features compared with current rotary nickel-titanium file systems. THE NEW CONCEPT The SAF file is hollow and designed as a thin cylindrical nickel-titanium lattice that adapts to the cross-section of the root canal. A single file is used throughout the procedure. It is inserted into a path initially prepar...

Background: Apple cider vinegar potentially can be used as an alternative to irrigation solutions because of its antibacterial compounds that inhibit Enterococcus faecalis, a pioneer bacteria cause root canal treatment failure. One the ideal solution requirements is it isn’t toxic oral cavity tissues, so it’s necessary run cytotoxicity test on apple solution. Cytotoxicity initial part evaluatio...

AIM The purpose of this study was to compare the antibacterial efficacy of three root canal irrigating solutions: An antibiotic containing irrigant, Chlorhexidine and Chlorhexidine + Cetrimide. METHODOLOGY 46 permanent maxillary central incisors were made into standardized segments and sterilized. 6 teeth were used to confirm sterility. The remaining 40 teeth were infected with Enterococcus f...

AIM To determine if the formation of para-chloroaniline (PCA) can be avoided by using an alternative irrigant following sodium hypochlorite but before chlorhexidine. METHODOLOGY Fifty-five single-rooted teeth were decoronated, instrumented to size 40, .06 taper whilst being irrigated with 14% ethylene-diamine-tetra-acetic acid (EDTA) and 6% NaOCl. Samples were then randomly divided into three...
