Domestic rabbits (Oryctolagus cuniculus) are increasingly popular as household pets; therefore, veterinarians need to be familiar with the most common diseases afflicting rabbits including dental diseases. Diagnostic approaches for dental disease include gross oral examination, endoscopic oral examination, skull radiography, and computed tomography (CT). CT overcomes many limitations of standar...

The purpose of this study was to study the absorbed dose in mouth due to scattering in teeth in dental radiography using the monte carlo simulation. The Electron Gamma Shower (EGS-4) system of computer codes was used, which is a general purpose package for Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies above a few ke...

Against this background, lack of reports on the...

Introduction: Radiography plays an important role in the diagnosis of oral and dental disease and one of the most common diagnostic procedures in dentistry. Recent reports have raised concern about the increased use of ionizing radiation in dental imaging and the possibility of cancers. The effective dose of some dental radiographic examinations is high enough, so appropriate ...
