Neuroblastoma is a nervous system malignancy. The extension of intra-abdominal neuroblastoma to the spinal canal is a rare condition. In this case report, we present a patient with monoplegia and a huge intra-abdominal mass with intra spinal extension and cord compression.

introduction: the purpose of this study was to evaluate external root surface temperature rise during post space preparation using la axxess bur, beefill pack system, and peeso reamer drill. materials & methods: the distal canals of forty-five extracted human permanent mandibular first molars were instrumented in crown-apical manner and obturated with lateral condensation technique. teeth were ...

Objective: Diagnosis of vertical root fractures (VRFs) is critical in endodontics. Cone Beam Computed Tomography (CBCT)  has significantly enhanced image quality compared to digital radiography (DR) and greatly aids the diagnosis of VRFs but, metal artifacts has remained as a problem in VRF detection.  This study evaluated the effect of intra canal posts on the diagnostic accuracy of CBCT and D...

Background The treatment of root canal infection consists of eradicating microbes from the root canal and preventing re infection by root filling. Though the existing intra canal medicaments fight against multidrug resistant microbes in root canal, still re-infections occurs. The objective of this study is to synthesize new b-lactam compounds and evaluate their antimicrobial activity to treat r...

An 8-year-old Warmblood gelding presented with a history of progressive ataxia for 6 weeks. Intra- and intervertebral ratios measured from lateral radiographs the cervical spine were within normal limits. Computed tomographic myelography revealed focal compression dorsal ventral contrast column as well displacement spinal cord canal due to bulging soft tissue attenuating material in half juncti...

introduction: effective durable adhesion between post material and dentine using resin cements is essential for longevity of restoration. the aim of this in vitro study was to compare the effect of different irrigants on smear layer removal after post space preparation. methods and materials: a total of 75 extracted anterior human teeth were selected. the canals were instrumented by rotary syst...

OBJECTIVE The aim of this study was to investigate in vivo microorganisms detected in root-filled teeth with post-treatment apical periodontitis and quantify colony-forming units (CFU) during endodontic retreatment. MATERIALS AND METHODS Fifteen root-filled teeth had their previous gutta-percha removed and were randomly instrumented before being divided into three groups and medicated with ei...

Procedure Following nonsurgical root canal treatment, a post space is created in the root canal by careful removal of the coronal canal obturating material. A sufficient amount of material must be retained in the apical portion of the canal to maintain an adequate apical seal. A custom or proprietary post is fitted and cemented into the root canal for core retention. The post should be passivel...

objectives: the main disadvantage of fiber posts is their low bond strength to root canal wall. the aim of the present study was to assess the effect of different root canal post space treatments on push-out bond strength of fiber posts to root dentin. materials and methods: after post space preparation in 40 endodontically treated human premolars, the teeth were randomly divided into four expe...

Objectives: The purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (DEC) could accelerate the amount of orthodontic tooth movement (OTM) in young adult mixed breed dogs. Methods: Fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. Orthodontic force...
