introduction : there is a direct relationship between the quality of root canal obturation and success of endodontic therapy. the aim of the present study was to assess the quality of canal obturation performed by undergraduate dental students at the faculty of dentistry, mashhad university of medical sciences, mashhad, iran. materials and methods: records of 200 endodontically treated teeth fr...

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 ...

AIM To ascertain the adoption of new endodontic technology in general dental practice in India in 2011. METHODOLOGY A postal questionnaire survey comprising 26 questions was sent to 700 general dental practitioners. The questions covered professional activity, root canal preparation and instrumentation, choice of irrigants and intracanal medicaments, choice of obturation techniques and other ...

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...

The regenerative endodontic procedure (REP) is an alternative solution for treatment of permanent teeth with incomplete root apex development. It results in angiogenesis, reinnervation, and further formation. Indications REP include immature necrotic pulp inflammatory lesions the periapical tissues. main contraindications comprise significant destruction tooth tissues a lack patient cooperation...
