Background Dental hardware produces streak artifacts on computed tomography (CT) images reconstructed with the standard weighted filtered back projection (wFBP) method. Purpose To perform a preliminary evaluation of an iterative metal artifact reduction (IMAR) technique to assess its ability to improve anatomic visualization over wFBP in patients with dental amalgam or other hardware. Mater...

BACKGROUND The aim of this study was to investigate the ability of Iranian medical and dental students in thinking critically and to assess their ability in using definite components of critical thinking (CT). METHODS Multistage cluster sampling was utilized to recruit 125 preclinical (1(st), 2(nd) and 3(rd) year of study) students in Yazd Shaheed Sadoughi University of Medical Sciences in Ya...

BACKGROUND Every endosseous dental implant is dependent on an adequate amount and quality of peri-implant hard and soft tissues and their fully functional interaction. The dental implant could fail in cases of insufficient bone and soft tissues or due to a violation of the soft to hard tissues to implant shoulder interface with arising of a secondary bone loss. METHOD To overcome this biologi...

PURPOSE Chronic musculoskeletal pain (CMSP) is associated with work stress and burn-out among registered dental hygienists, with prevalence estimates ranging between 64 to 93%. Complementary and alternative medicine (CAM) therapies can be helpful in managing CMSP. The purpose of this study was to determine if dental hygienists who use CAM have greater career satisfaction compared to convention...

PURPOSE To evaluate the relative value of magnetic resonance (MR) imaging versus computed tomography (CT) in the diagnosis of inflammatory paranasal sinus disease. MATERIALS AND METHODS In 30 patients suspected of having or known to have inflammation of the paranasal sinuses, both coronal CT and coronal T1-weighted, three-dimensional, gradient-echo MR imaging of the paranasal sinuses were per...

We present a case of odontogenic maxillary sinusitis whose sinonasal symptomatology was thought to be the consequence of a previous midfacial trauma. The patient was admitted to the Clinic of Oral and Maxillofacial Surgery after more than 10 years of exacerbations of sinonasal symptoms, which began to plague soon after a facial contusion. We decided to perform CT of paranasal sinuses, and despi...

Dentists can be a funny bunch. We all, for the most part, like new technology and gadgets, yet it is very difficult for some of us to change the way we do things, especially when it comes to our practices. Some of our colleagues would be content if they could continue doing procedures and using clinical techniques just as they learned them in dental school. If they never had to learn anything n...

UNLABELLED Cone-beam CT is an exciting development in dental and maxillofacial imaging. This article gives an overview of the subject and discusses some of the implications for dental practitioners. CLINICAL RELEVANCE Dentists should be aware of technological advances that potentially are going to have major implications on their practice. They should have knowledge of the indications, limita...
