introduction: the aim of this in vitro study was to evaluate the effect of canal dryness on the push-out bond strength of two resin sealers (ah-plus and adseal) and a bioceramic sealer (endosequence bc sealer) after canal irrigation with sodium hypochlorite (naocl) and chlorhexidine (chx). methods and materials: a total of 18 extracted human premolars were used. canals were prepared and were di...

introduction: fearless removal of tooth structure during canal preparation and shaping has negative effects on the prognosis of treatment. on the other hand, sufficient pre-enlargement facilitates exact measurement of the apical size. the present in vitro study aimed to compare the efficacy of gates-glidden drills, k3, protaper, flexmaster and race instruments in dentin removal during coronal f...

The main objectives of root canal treatment are thorough shaping and cleaning of all pulp spaces and its complete obturation with an inert filling material. The presence of untreated canal may be a reason for failure of endodontic therapy. To achieve satisfactory root canal therapy, a proper and in-depth knowledge of complex and abnormal root canal morphology is essential.

adequate cleaning, shaping and filling of the root canal system are mandatory for successful root canal treatment. thorough knowledge of root canal morphology and unusual anatomy of the tooth is critical for the practitioner. the occurrence and location of the third mesial canal (middle mesial canal) in mandibular first and second molars in relation to other two mesial canals that were treated ...

Maxillary lateral incisors usually exhibit a single root with a single canal. However, maxillary lateral incisor teeth with unusual morphology of root canal system are frequently reported. These cases of variable root canal anatomy can be treated well by nonsurgical endodontic methods. A detailed description of root canal morphology is fundamental for successful endodontic treatment. Treatment ...

INTRODUCTION The aim of this study was to evaluate root canal anatomy of mandibular first molars (MFM) in a selected Iranian Population using clearing technique. METHODS AND MATERIALS A total of 150 extracted MFMs were cleared. The root canal morphology (including the root numbers and root length) and the anatomy of the root canal system (including is the number and type of canals based on Ve...

Endodontic therapy of mandibular molars is a challenging task due to its varied root canal morphology. A mandibular first molar with additional buccal root (Radix paramolaris) and additional distolingual root (Radix Entomolaris) is an example of its varied anatomy. A successful management of atypical root canal configurations is an important aspect in determining the success rate of root canal ...

The aim of the present study was to examine the morphology of root canals in premolar teeth with completely formed root apices. The material consisted of 139 extracted premolar teeth, including 83 first premolars (59.7%) and 56 second premolars (40.3%). Maxillary teeth made up 64% of the material and mandibular teeth 36%. In order to measure the actual root canal length an endodontic instrument...
