Osteochondroma is an osseous protuberance with cartilaginous growth potential that usually forms at the ends of long bones such as knee, hip, shoulder and joints(1). Osteochondromas are one of the most common benign tumours of bone, approximately 35% to 50% of all benign tumors and 8% to 15% of all primary bone tumors (2). Only about 1% of these occur within the head and neck region (1). The mo...

High-resolution real-time tomography of scattering tissues is important for many areas of medicine and biology1-6. However, the compromise between transverse resolution and depth-of-field in addition to low sensitivity deep in tissue continue to impede progress towards cellular-level volumetric tomography. Computed imaging has the potential to solve these long-standing limitations. Interferomet...

introduction : one of the key factors in successful endodontic therapy is to adequately fill the root canals. the aim of this in vitro study was to compare the quality of four different root canal obturation techniques: cold lateral condensation (clc), warm vertical condensation (wvc), obtura ii (oii) and gutta flow (gf) by using micro-computed tomography (micro ct). materials and methods: a to...

Background: Cone-beam computed tomography (CBCT) scanners for image-guided radiotherapy are in clinical use today, but there has been no consensus on uniform acceptance to verify the CBCT image quality yet. The present work proposed new methods to fully evaluate the performance of CBCT in its three-dimensional (3D) reconstruction space. Materials and Methods: Compared to the traditional methods...
