Recently, several in vitro and in vivo studies demonstrated promising results about the use of photodynamic therapy during root canal system disinfection. However, there is no consensus on a standard protocol for its incorporation during root canal treatment. The purpose of this study was to summarize the results of research on photodynamic therapy in endodontics published in peer-reviewed jour...

An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively and should be treated by both endodontic therapy and surgery. A case of dens invaginatus Type 3 in a maxillary lateral incisor with a periapical lesion and its successful trea...

The key goals of endodontic therapy include the removal of pulp remnants, necrotic tissue, micro-organisms, and microbial byproducts from the root canal system. Although this may be achieved through endodontic preparation, complete removal is difficult because of the intricate root canal anatomy [1]. Isthmi, apical deltas, intercanal communications, and loops are commonly observed in root canal...

Thorough knowledge of root canal morphology is essential for the endodontic therapy. There are rare variations in canal number and configuration in maxillary molars, which could affect treatment outcome. This paper presents the endodontic management of a maxillary first molar with two palatal canals in one root (Vertucci type IV) and a single buccal canal. In this paper cone-beam computed tomog...

Background: Knowledge about the anatomy of root canals is an important facror in the prognosis of  root canal  therapy .The purpose  of  this  study is to derermine  the root  canal anatomy in  mandibalar anterior  reeth and  premolars by clear and dye peneration method. Materials and methods:In this  study, 350 human mandibular anterior teeth and  mandibular  and  maxillary premolars(from e...

Introduction Pain control following root canal therapy is a challenging issue in dentistry. This double-blind study aimed to compare the effectiveness of Celebrex and celecoxib used to control post-endodontic pain. Material and Methods In this randomized, double-blind study, 43 patients with symptomatic teeth were selected. The subjects gave their consent for a prophylactic oral administrati...

Understanding the morphology of the root canal plays a key role in the success of a root canal therapy. Thus considerations of the anatomic variations, in the process of diagnosis and treatment of the maxillary and mandibular posterior teeth, should be done by the clinicians.1 A thorough examination of pre-operative and postoperative radiagraphs plays a critical role in endodontic success. Vari...

The awareness of internal dental morphology is an excessively critical step in management of endodontic therapy. [1] The mandibular first molar, the earliest permanent tooth to erupt is assumed to be the tooth that mostly creates need for root canal treatment. The most common root canal morphology of the mandibular first molar is the presence of two canals in the mesial root and one or two cana...

One primary objective of endodontic therapy is to establish an adequate seal with the root canal filling material. The placement of an immediate amalgam buildup at obturation, in conjunction with rubber dam isolation, allows an endodontic seal to be extended from the foramen to the cavosurface margin. As a result of this immediate buildup, the length of the seal and the longevity of the endodon...
