The purpose of this in vitro study was to investigate the canal configuration types, and the prevalence and location of anatomical variations in the mesiobuccal (MB) and mesial roots of permanent maxillary and mandibular first molars after instrumentation. The number and the type of canals were determined before instrumentation using conventional methods. All root canals from the 47 MB roots an...

AIM To evaluate the incidence of anatomical variations and abnormalities of the third ventricle floor encountered during the endoscopic third ventriculostomy (ETV) procedure in myelomeningocele-associated hydrocephalus (MAH) cases. MATERIAL AND METHODS A retrospective analysis was performed on 455 pediatric MAH cases that had been treated with ETV. This case series consisted of the patients w...

BACKGROUND AND PURPOSE Daily anatomical variations can cause considerable differences between delivered and planned dose. This study simulates and evaluates these effects in spot-scanning proton therapy for lung cancer patients. MATERIALS AND METHODS Robust intensity modulated treatment plans were designed on the mid-position CT scan for sixteen locally advanced lung cancer patients. To estim...

OBJECTIVE Anatomical variations of the dental canal structures are present in a small proportion of the population and often go undiagnosed. In such cases, there could be an increased risk of complications during surgery and failure of anesthesia. The aim of this study was to search for anatomical anomalies in a relatively large random population by using 3-T high-field magnetic resonance imagi...

  Background: Variations of the brachial plexus are common and a better awareness of the variations is of crucial importance to achieve successful results in its surgical procedures. The aim of the present study was to evaluate the anatomical variations of the brachial plexus in adult cadavers.   Methods: Bilateral upper limbs of 32 fresh cadavers (21 males and 11 females) consecutively referre...

INTRODUCTION The intracranial vascular anatomical variations, although rare, represent a interesting field of research, since many anomalous variants are possible and in most cases they remain asymptomatic. The capability of the cerebral circulation to adapt to several flow changes is confirmed by the fact that in several cases these anatomical variation compensate for an eventual unsuccessful ...

Objective: The aim of this study was to detect and describe the existence and incidence of anatomical variations of the coeliac trunk by Using imaging technique. Materials and Methods: 80 patients visited the, radiology department of S.M.S.MEDICAL college jaipur . To cover the whole abdominal aorta in each patient, spiral CT angiography scan will be made and thin slices (0.6 mm) axial images wi...

PURPOSE Despite the fact that anatomical variations of the celiac trunk are well explored in the literature, information on these vessels diameters is scanty. The aims of the present study were to describe the arterial diameters of the celiac trunk and its main branches, and to investigate if these diameters are altered in those cases presenting anatomical variations of these vessels. METHODS...

AIM To highlight anatomical variation in the mandibular canine. SUMMARY Two clinical case reports are presented to illustrate anatomical variation in the human mandibular canine. Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment procedures. Many investigators have reported the anatomical variations associated with mandibular can...

Back Ground: Sinusitis affects millions of people each year and is a major cause of concern worldwide. Chronic rhino-sinusitis is an inflammation of Nose and Paranasal sinuses and the aetiology of it is multifactorial. Anatomical variations of nose and paranasal sinuses are one of the most important aetiological factor for chronic sinusitis. The approach to patients with chronic rhinosinusitis ...
