Dynamics and kinematics of the angular vestibulo-ocular reflex in monkey: effects of canal plugging. J. Neurophysiol. 80: 3077-3099, 1998. Horizontal and roll components of the angular vestibulo-ocular reflex (aVOR) were elicited by sinusoidal rotation at frequencies from 0.2 Hz (60 degrees/s) to 4.0 Hz ( approximately 6 degrees/s) in cynomolgus monkeys. Animals had both lateral canals plugged ...

Cartilage canals have been shown to contain discontinuous blood vessels that enable circulating bacteria to bind to cartilage matrix, leading to vascular occlusion and associated pathological changes in pigs and chickens. It is also inconsistently reported that cartilage canals are surrounded by a cellular or acellular wall that may influence whether bacterial binding can occur. It is not known...

Success of endodontic treatment requires the knowledge and morphology of root canal anatomy. Undetected additional canals in mandibular premolar is a common reason for endodontic failure. This presents with diagnostic difficulty and subsequent flare ups and poor prognosis. Location of additional canals is the key to successful endodontic management. This case report describes endodontic managem...

introduction: file fracture is one of the main procedural mishaps in endodontic treatment. the aim of this in vitro study was to compare the fracture rate of three niti rotary systems; hero 642, mtwo and flexmaster in artificial canals. methods and materials: in this study, bovine long bone was used. after primary preparation of bones, longitudinal sections with 4-cm diameter were cut and encod...

UNLABELLED Need for the study: The most important procedure for a successful endodontic treatment is the cleaning and shaping of the canal system. Understanding the internal anatomy of teeth provides valuable information to the clinician that would help him achieve higher clinical success during endodontic therapy. AIMS To evaluate by computed tomography-the internal anatomy of mandibular sec...

INTRODUCTION This study analyzed the in vivo microbiological status of the root canal systems of mesial roots of mandibular molars with primary apical periodontitis after 1- or 2-visit endodontic treatment. METHODS Mesial root canals were instrumented by using either a combination of K3 and LightSpeed instruments (mesiobuccal canals) or the ProTaper system (mesiolingual canals), with 5% NaOCl...
