Objective. To determine the structural features of root canals mandibular premolars and molars, to assess quality endodontic treatment on basis cone-beam computed tomography (CBCT). Materials methods . The structure 50 teeth (premolars molars mandible) after performed was studied retrospectively CBCT in patients. number roots, as well their angle inclination, presence additional were taken into...

INTRODUCTION Exploration and determination of the relationship between stature and length of tooth is essential in Paleontology, Forensic Odontology and Endodontology. This study aimed to determine any association between stature and posterior tooth length in a group of patients who required root canal treatment. METHODS Age, sex and standing height of adults were considered for posterior too...

INTRODUCTION The purpose of this retrospective study was to determine the anesthetic success of the inferior alveolar nerve (IAN) block, and supplemental articaine buccal infiltration after a failed IAN block, in first and second molars and premolars in patients presenting with symptomatic irreversible pulpitis. METHODS As part of 6 studies, 375 emergency patients presenting with symptomatic ...

AIMS Prediction of the mesiodistal crown width of unerupted canines and premolars is an important aspect of mixed dentition analysis. The accuracy of Tanaka-Johnston equations, the most commonly method, is questionable when it is applied to different ethnic groups. In this study, we aimed to develop a new regression equation for this prediction in an Iranian population. MATERIALS AND METHODS ...

The aim of the present roentgenographic in vitro study was to determine the initial straight length from the cemento-enamel junction (CEJ) to the appearance of a root canal curvature in human mandibular premolars. A total number of 282 mandibular premolars were examined. Exclusion criteria comprised root caries, extensive restorations and endodontically treated teeth. The teeth were fixed and d...

Introduction. Mandibular premolars have been reported with complex anatomical aberrations, making them one of the most difficult teeth to manage endodontically. Methodology. An exhaustive search was undertaken to identify associated anatomic studies of mandibular premolars through MEDLINE/PubMed database using keywords, and a systematic review of the relevant articles was performed. Chi-square ...

Background and aim: The mental-incisive nerve block can be used where lower premolars and anterior teeth require treatment. The aim of this study is to compare tow methods ofmental-incisive nerve block for extraction of the lower premolars and anterior teeth. Methods and materials: This randomized double blind split-mouth clinical trial study was performed on patients requiring extraction of lo...

Premolars rank third in frequency after third molars and maxillary canines in impacted or unerupted teeth. Failure to detect and analyze the problem may lead to unnecessary space loss, crowding, or collapse of the dental arch. A diagnostic scheme is presented to facilitate diagnosing and treating unerupted premolars. Important observations include: Diagnosing congenitally missing permanent teet...
