Objective: To compare the effect of Maleic acid and Irritrol (combination Chlorhexidine & Ethylenediaminetetraacetic acid) irrigation on sealing ability Biodentine when used as root-end filling material. Material Methods: Thirty single-rooted human premolars were subjected to standardized root canal instrumentation irrigated with 2.5% Sodium Hypochlorite (NaOCl) after each instrument change. Ap...

Kazemifar** *- Assistant Professor of Endodontics Dept. - Faculty of Dentistry – Tehran University of Medical Sciences. **- Dentist. Background and Aim: Coronal sealing plays an important role in the prevention of root canal system reinfection and the access of irritants to peri...
Extra oral comparison of smear layer removal from root canals when using phosphoric acid and RCprep–NaOCL: A SEM study Dr. M. Zare Jahromi * - Dr. MR. Malekipour ** - Dr. F. Sobhi *** *Assistant Professor of Endodontics Dept., Faculty of Dentistry, Khorasgan Islamic Azad University. **Assistant Professor of Operative Dentistry Dept., Faculty of Dentistry, Khorasgan Islamic Azad University. ***D...
OBJECTIVE The purpose of this study was to evaluate the sealing ability of castor oil polymer (COP), mineral trioxide aggregate (MTA) and glass ionomer cement (GIC) as root-end filling materials. Forty-five single-rooted human teeth were cleaned and prepared using a step-back technique. The apical third of each root was resected perpendicularly to the long axis direction. All teeth were obturat...
AIM The study was designed to quantitatively evaluate the quality of root canal preparation and root canal obturation in canals treated with either rotary or self adjusting files, using three-dimensional micro-computed tomographic (CT) analysis. METHODOLOGY Pair-matched root canals were instrumented with either rotary nickel-titanium files or self-adjusting files following the manufacturers' ...
Microbes are considered as the primary etiologic agents in endodontic diseases. The ways of reducing these agents are: root canal debridement, antimicrobial irrigants and antibacterial filling materials. But the complexity of the pulp canal system presents a problem for chemo mechanical preparation. One of the factors determining the success of endodontic treatment is the sealing material with ...
Background and Aim: Complete obturation of the prepared root canal is an essential step in endodontic treatment. Combination of gutta-percha and a sealer is widely used in clinical practice for root canal obturation, thus microleakage studies on sealing properties of these materials constitute an important part of endodontic researches. The aim of this study was to evaluate the microleakage of ...
his study evaluated the sealing ability of apical plugs fabricated with gray MTA Angelus sealer, CPM TM sealer and MBPc sealer. The root canals of 98 extracted single-rooted human teeth were instrumented with #5 to #1 Gates Glidden drills according to the crown-down technique until the #1 drill could pass through the apical foramen. The specimens were then prepared with K-files, starting with a...
INTRODUCTION Root canal sealers used in odontological applications are capable of providing an apical seal, thus inhibiting potential bacterial penetration into the periradicular tissues. Since insolubility is the ideal characteristic for a root canal sealer material, in dentistry the sealability of the material depends on its solubility. PURPOSE This study tested the solubility of six differ...
