microorganisms play a major role in initiation and perpetuation of pulpal and periapical diseases. therefore, elimination of the microorganisms present in the root canal system is the fundamental objective of endodontic treatment. the use of mechanical debridement, chemical irrigation or other antimicrobial protocols and intra-canal medicaments are critical to attain this goal. the aim of this ...

introduction: the aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (cbct) in northern iranian population and also to indicate the thinnest area around root canals. methods and materials: we evaluated cbct images of 154 first molars and 147 second molars. by evaluating three axial, sagittal and coronal planes of...

this case report presents an uncommon case of maxillary molar with two palatal root canals and an enamel pearl in the furcation area. the article discusses root canal complexities of maxillary second molars as well as possibility of coexisting anomalies in the region that makes radiographic interpretation difficult and compromises the success of endodontic treatment.

Background and Aim: The main goal of root canal treatment is to prevent or treat apical periodontitis. The aim of the present study was to assess the coronal restoration status, root canal filling quality, periapical health condition, and related factors in endodontically treated teeth at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2011-12. Materials and...

Complex and unusual root canal morphology is an often occurring phenomenon. Understanding the unusual root canal morphology contributes to success in endodontic treatment. One such variant root canal morphology is the 'S' shaped or bayonet shaped root canal. This case report discusses endodontic treatment of a maxillary second premolar with an 'S' shaped root canal.

the success of endodontic therapy requires knowledge of the internal and external dental anatomy and its variations in presentation. this case report involves endodontic treatment of a traumatized maxillary central incisor with two separate roots.

Background The treatment of root canal infection consists of eradicating microbes from the root canal and preventing re infection by root filling. Though the existing intra canal medicaments fight against multidrug resistant microbes in root canal, still re-infections occurs. The objective of this study is to synthesize new b-lactam compounds and evaluate their antimicrobial activity to treat r...

OBJECTIVE The aim of the present study is to assess the root and root canal morphology of maxillary and mandibular premolars in a Turkish population by using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this study, CBCT images of 2134 premolars (987 maxillary, 1147 mandibular) were obtained from 404 patients. Details of gender, age, number of roots and canals, and canal conf...

Aim. To determine the root and canal morphology of permanent maxillary first molars in a Sri Lankan population with special emphasis on the presence of a second canal in the mesiobuccal root. Materials and Methods. One hundred and fourteen permanent maxillary first molars were examined. The root numbers of the molars were recorded. Root canal morphology was studied using a clearing technique. T...
