The focus of this article is diagnostic imaging used for the evaluation of temporomandibular disorders and orofacial pain patients. Imaging modalities discussed include conventional panoramic radiography, panoramic temporomandibular joint imaging mode, cone beam computed tomography, and magnetic resonance imaging. The imaging findings associated with common(More)
OBJECTIVE The objective of this study was to determine if phosphor plates used in predoctoral clinics are microbiologically contaminated and to identify the source of contamination. STUDY DESIGN Forty-five of 300 phosphor plates (15%) were randomly selected for examination. The plates were pressed into individual blood agar plates, were incubated using(More)
OBJECTIVE This study was performed to determine: 1) the rate and source of microbiologic contamination of photostimulable phosphor plates (PSP) in a predoctoral clinic; and 2) whether a combination of weekly gas sterilization and barrier protocols can prevent contamination of PSP plates. METHODS Fifty plates in clinical use and 25 gas-sterilized control(More)
OBJECTIVE To test the null hypothesis of no difference in caries detection in dim, bright, and hooded environments for laptop viewing of intraoral radiographs. STUDY DESIGN Extracted posterior teeth were imaged with posterior bite wing geometry by using storage phosphor plates. Images were displayed on a laptop computer placed in 3 lighting environments.(More)
OBJECTIVES To compare the accuracy of local computed tomography (LCT) and conventional radiography for proximal caries detection and depth assessment. STUDY DESIGN An in vitro model was used consisting of 20 extracted posterior teeth with 18 caries lesions. Local computed tomography slices were reconstructed in axial and parasagittal planes from 100 basis(More)
OBJECTIVE The aim of the study was to evaluate the image quality of a photostimulable phosphor (PSP) plate system to determine if image degradation has occurred after a number of clinical uses. STUDY DESIGN Twenty DIGORA Optime PSP plates (Soredex Orion Corp., Helsinki, Finland) were imaged throughout clinical use. Image quality was assessed by using(More)
PURPOSE This study assessed the effectiveness of three antimicrobial mouthrinses in reducing microbial growth on photostimulable phosphor (PSP) plates. MATERIALS AND METHODS Prior to performing a full-mouth radiographic survey (FMX), subjects were asked to rinse with one of the three test rinses (Listerine®, Decapinol®, or chlorhexidine oral rinse 0.12%)(More)
PURPOSE To evaluate the upper airway dimensions of obstructive sleep apnea (OSA) and control subjects using a cone-beam computed tomography (CBCT) unit commonly applied in clinical practice in order to assess airway dimensions in the same fashion as that routinely employed in a clinical setting. MATERIALS AND METHODS This was a retrospective analysis(More)
This study's purpose was to describe a case involving the discovery of a foreign body in the ear canal of an eight-year-old boy, revealed during a recall evaluation to a dental clinic. A panoramic radiograph revealed a radiopaque object in the area of the external auditory meatus. The patient's mother reported one incidence of reported ear pain that(More)
OBJECTIVE The aims of this study were (1) to subjectively quantify the degree of scratching and smudging that had taken place in the junior clinic in the 9 months following the implementation of digital radiology; (2) to compare the findings with a previously published report; and (3) to identify areas in the protocol and training that can be refined to(More)
