Root canal irrigants play a significant role in the elimination of microorganisms, tissue dissolution, and the removal of debris and smear layer. Sodium hypochloride is the most commonly used endodontic irrigant, despite limitations. None of the presently available root canal irrigants satisfy the requirements of ideal root canal irrigant. Newer root canal irrigants are studied for potential re...
ABSTRACT By restoration of pulpally exposed teeth with root canal therapy edentulous areas and neighbouring teeth displacement can be avoided. Prefabricated posts may be used for crown restoration of these teeth. For the preparation of root canal for post placement, Gutta percha should be removed by means of mechanical, thermal and chemical agents. To study the amount of apical leakage in vit...
Comparative study on canal preparation by three rotary sys-tems using CT scan (An in vitro study) Dr. M.H. Zarrabi* - Dr. A. Talati** - Dr. S. Moradi** - Dr. L. Shakeri*** * - Associate Professor and Chief of Endodontics Dept. - Faculty of Dentistry – Mashhad University of Medical Sciences. **- Assistant Professor of Endodontics Dept. - Faculty of Dentistry – Mashhad University of Medical Scien...
Background and Aim: Elimination of microorganisms and their byproducts from root canal system is one of important aims of root canal therapy. This object is gained by using of many chemomechanical techniques but with noncertain success. A new method is used of nonpathogenic bacteria for growth inhibition of pathogenic bacteria, Antibiosis, in root canal therapy.The aim of this study was in vitr...
familiarity with the normal and abnormal anatomy of the root canal system is essential for successful root canal treatment. the possibility of concomitant three-rooted and three- canalled maxillary and mandibular premolars are extremely rare. the purpose of this paper was to report a case with a three-rooted maxillary first premolar and two three-rooted mandibular premolars.
Background and Aims: Estimating the canal length is essential for reaching to a proper endodontic treatment. Any error and miscalculation in estimation of the working length, especially in curved canals, can result in complication during and after root canal therapy. The introduction of digital radiography has enabled us to measure curved canal length. The purpose of this study was to evaluat...
The present study was conducted to determine the number of roots and morphology of the root canal system of permanent mandibular first molars (M1) in a Sri Lankan population. Sample of 529 M1 teeth was used. The number of roots was examined and the lengths of the mesial and distal roots were measured to the nearest 0.01 mm. Vacuum injection protocol was used to inject China ink into the root ca...
To ensure the long-term success of root canal treatment, it is essential to access, clean, and fill all of the canal spaces. However, the anatomic complexities and variations are constant challenges for successful endodontic therapy.1 The morphology of the maxillary first molar has been extensively studied and reported in the literature. Studies have revealed a high incidence of double canal sy...
INTRODUCTION The main goal of endodontic therapy is to prevent or heal apical periodontitis. However, root canal anatomy might present a clinical challenge directly related to the treatment outcome. The purpose of this study was to review published literature related to root anatomy and root canal configuration of the permanent mandibular first molar. METHODS An exhaustive search was undertak...
Evaluation of different clearing techniques: An auxiliary method for studying root canal anatomy Dr. M. Vatanpour* - Dr. M. Javidi** * Resident of Endodontics Dept., Faculty of Dentistry, Mashhad University of Medical Sciences. ** Assistant Professor of Endodontics Dept., Faculty of Dentistry, Mashhad University of Medical Sciences.Background and Aim: Various techniques for clearing the root ca...
