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...

Aim. To investigate the root canal anatomy of single-rooted permanent maxillary and mandibular canines in an Indian population using cone beam computed tomography (CBCT). Methodology. A total of 250 permanent maxillary canines and 250 permanent mandibular canines were selected and scanned using CBCT. The root anatomy of each tooth was evaluated for the following parameters: the pattern of the r...

OBJECTIVES It is essential for clinicians to have adequate knowledge about root canal configurations; although its morphology varies largely in different ethnicities and even in different individuals with the same ethnic background. The current study aims to review the root canal configurations of mesiobuccal roots of maxillary first molars in an Iranian population based on different epidemiolo...

BACKGROUND Meniscal root tears present in many forms and can have profound consequences on the health of knee articular cartilage. While the biomechanics, natural history, and treatment of root tears have been increasingly investigated, the spectrum of meniscal root tear patterns observed during arthroscopic examination has yet to be defined and categorized. PURPOSE To establish a classificat...

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...

introduction: the purpose of this study was to investigate the root and canal morphology of maxillary first molars with regards to patients’ age and gender with cone-beam computed tomography (cbct). methods and materials: a total of 149 cbct scans from 92 (67.1%) female and 57 (31.3%) male patients with mean age of 40.5 years were evaluated. tooth length, presence of root fusion, number of the ...

adenomatoid odontogenic tumor (aot) is a benign odontogenic tumor with slow but progressive growth. the three variants: follicular, extra follicular (both central type), and peripheral present withidentical histologic findings. this case report describes a patient with a large aot in the mandibleof the extra follicular type which is the less common of the two central types. it also strikes as a...

The root cap is increasingly appreciated as a complex and dynamic plant organ. Root caps sense and transmit environmental signals, synthesize and secrete small molecules and macromolecules, and in some species shed metabolically active cells. However, it is not known whether root caps are essential for normal shoot and root development. We report the identification of a root cap-specific promot...
