INTRODUCTION The aim of this study was to evaluate the effects of training duration and case difficulty on the radiographic quality of root canal fillings performed by dental students in Saudi Arabia. METHODS AND MATERIALS A longitudinal cohort study was conducted at King Saud University. Root canal treatments performed by 55 dental students from 2012-2014 were included in the study. Each stu...
AIM The aim of this study was to investigate the quality of endodontic and coronal restorations and the association with periapical status in a Danish population. METHODOLOGY A total of 614 randomly selected individuals (20-60+ years of age) from Aarhus County had a full-mouth radiographic examination. The quality of endodontic and coronal restorations and the periapical status of endodontica...
Dental radiography is an essential component in the delivery of high-quality dental care for dogs and cats. During the 1980s veterinarians began taking radiographs of teeth using standard radiographic units; however, these units made patient positioning difficult and often resulted in suboptimal films. In the 1990s dental radiographic units became a more common part of the veterinary dental dia...
Introduction In radiography, dose and image quality are dependent on radiographic parameters. The problem is caused from incorrect use of radiography equipment and from the radiation exposure to patients much more than required. Therefore, the aim of this study was to implement a quality-control program to detect changes in exposure parameters, which may affect diagnosis or patient radiation do...
OBJECTIVE To investigate whether patients with severe radiographic osteoarthritis (OA) have a different outcome at one year after total hip replacement than patients with moderate radiographic OA. To investigate sex related differences in preoperative radiographic and self reported status and in postoperative outcome. METHODS 184 patients (96 women) with a mean age at surgery of 71.4 years (5...
Introduction: The introduction of digital radiography has led to a significant problem in terms of dose creep. To address this problem, manufacturers have established a set of exposure indicators (EI) as a feedback mechanism to safeguard against overexposure. The EI is the measure of incident exposure to the detector that is directly proportional to the signal-to-noise...
BACKGROUND Currently the standard femoral cementing technique requires cement injection gun to deliver bone cement into the femoral canal. The standard cement gun is expensive and must be imported. There is no previous study about the use of a household caulking gun for femoral cementation. OBJECTIVE To compare the radiographic quality of cementing technique in proximal femur between using st...
At present, the American Dental Association and the American Academy of Oral Maxillofacial Radiology have guidelines for the dental environment that include quality assurance and control of film-based radiography. Approximately 19%-30% of US dental offices currently use some form of digital intraoral radiography, and growth is expected to continue. It is anticipated that new tools and guideline...
