Procedure related factors define the success of root canal procedures in majority of the cases. While there are several guidelines available, the compliance rate is substantially low. This study evaluates the attitudes, materials and methods preferred in root canal therapy by dentists in Palestine. An online self-administered questionnaire was sent to 200 Palestinian dentists. The questionnaire...

INTRODUCTION The aim of this in vitro study was to identify the root and canal morphology of maxillary first and second molars in Iranian population by taking and analyzing cone-beam computed tomography (CBCT) scans. METHODS AND MATERIALS Extracted maxillary first (n=125) and second (n=125) molars were collected from native Iranians and scanned by using a CBCT scanner. The number of roots and...

INTRODUCTION General dental practitioners provide the majority of treatment in Iran. The aim of this study was to gather information on the methods, materials and attitudes employed in root canal treatment by dentists participated in 7(th) Congress of Iranian Academy of Restorative Dentistry in Shiraz /2007 in order to evaluate the quality of current practice. MATERIALS AND METHODS A question...

INRODUCTION High-quality filling of root canals is one of indicators of successful endodontic treatment. However, poor-quality of the filling is still a common phenomenon in the work of general practitioners. Better training of dental students of modern odontology is possible solution of the problem. The aim of this study was to evaluate the quality of root canal filling performed by undergradu...

A simulated curved root canal in a resin block was enlarged to size 40 and used to compare the depth of accessory cone penetration and weight of obturation occurring with the use of different obturation techniques and spreader-accessory cone combinations. Twelve groups, each consisting of 10 obturations, were created. A conventional lateral condensation technique was used in six groups and a me...

BACKGROUND Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur. CASE REPORT Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical lo...

Mineral trioxide aggregate (MTA) has been recommended for pulp capping, pulpotomy, apical barrier formation in teeth with open apexes, repair of root perforation and root canal obturation. Since, its introduction in 1993 by Torabinejad numerous studies have been published regarding various aspects of this material. The aim of this review was to consider MTA as root canal sealer and various labo...

INTRODUCTION Success of non-surgical root canal treatment is predicted by meticulous cleaning and shaping of the root canal system, three-dimensional obturation and a well-fitting "leakage-free" coronal restoration. The techniques of obturation that are available have their own relative position in the historical development of filling techniques. Over the years, pitfalls with one technique hav...

BACKGROUND Successful root canal treatment depends on proper cleaning, disinfecting and shaping of the root canal space. Pulpless teeth have lower dentin microhardness value compared to that of vital teeth. A material which can cause change in dentin composition may affect the microhardness. Thus the aim of this study was to evaluate and compare the effect of two root canal sealers on dentin mi...
