During the treatment process for benign paroxysmal positional vertigo (BPPV) using canalith repositioning procedure, otolith can inadvertently enter semicircular canal instead of utricle. Canal conversion refers to situation where enters a different canal, while reentry occurs when returns same canal. The occurrence complicate accurate diagnosis and BPPV, potentially leading misdiagnosis unsucc...

Introduction: To achieve a successful endodontic treatment, the clinician has to identify the different canal configurations.mandibular premolars have the wide variety of root canal morphology and they are known as the most difficult teeth to treat in endodontics.CBCT  provides a non-invasive 3D confirmatory diagnosis as a complement to conventional radiography.The aim of this study was to...

The hypoglossal canal is a permanent element of the human skull. As well as the hypoglossal nerve, the canal also contains the venous plexus and an arterial branch leading to the dura mater. It emerged from our earlier studies that the venous plexus is a dominant component in this canal. In the present work the morphology and dimensions of the canal were studied on macerated skulls of humans an...

We studied the spatial characteristics of 45 vestibular-only (VO) and 12 vestibular-plus-saccade (VPS) neurons using angular rotation and static tilt in two cynomolgus monkeys. The purpose was to determine the contribution of canal and otolith-related inputs to central vestibular neurons whose activity is associated with the central velocity storage integrator. Lateral canal-related neurons res...

OBJECTIVES This biomechanical study captured the reamer pathway in human femurs reamed through a greater trochanteric entry portal. The spatial pathway of the reamed intramedullary canal was analyzed to determine how closely a helix can match the dimensions of this canal. METHODS Twenty-one human cadaveric femurs were reamed through a trochanteric entry portal 12 mm lateral to the superior tr...

PURPOSE This study evaluated the association between cone beam computed tomography (CBCT) and panoramic radiographs in the assessment of a superimposed relationship between the mandibular canal and impacted third molars. MATERIALS AND METHODS The study samples consisted of 175 impacted third molars from 131 patients who showed a superimposed relationship between the mandibular canal and third...
