Conebeam computed tomography (CBCT) is a technology new to dentistry that provides 3-D imaging of the oral and maxillofacial complex. Bitewing, periapical, and panoramic images are commonplace for diagnosis and treatment planning in dentistry. The 3-D data provided by conebeam technology uses a low quantity of radiation and provides insight into anatomy as an adjunct to 2-D imaging. As 3-D imag...

It is difficult to take intraoral radiographs in some patients who are intolerable to place the film in their mouth. For these patients, Newman and Friedman recommended a new technique of extraoral film placement. Here we report various cases that diagnostic imaging was performed in patients using the extraoral periapical technique. This technique was used to obtain the radiographs for the pati...

objectives: this study aimed to compare the diagnostic accuracy of inverted and unprocessed digitized periapical radiographs for detection of peri-implant defects. materials and methods: a total of 30 osteotomy sites were prepared in three groups of control, study group 1 with 0.425 mm defects and study group 2 with 0.725 mm defects using the sic and astra tech drill systems with 4.25mm and 4.8...

objectives: this study sought to assess the diagnostic accuracy of cone beam computed tomography (cbct) with different voxel sizes and intraoral digital radiography with photostimulable phosphor (psp) plate for detection of periapical (pa) bone lesions. materials and methods: in this ex vivo diagnostic study, one-millimeter defects were created in the alveolar sockets of 15 bone blocks, each wi...

Bacterial infections of the dental pulp result in tissue destruction and periapical bone resorption. The availability of genetically engineered mouse strains is a major advantage in the use of this model system for studies of periapical pathogenesis. The main limitation of the mouse model is its small size, and the necessity for laborious histologic analyses to quantify periapical bone destruct...

PURPOSE The purpose of this clinical feasibility study was to evaluate the applicability of magnetic resonance imaging (MRI) for the assessment of apical periodontitis in direct comparison with cone beam CT (CBCT). MATERIALS AND METHODS 19 consecutive patients (average age 43 ± 13 years) with 34 lesions in total (13 molars, 14 premolars and 7 front teeth) were enrolled in this feasibility stu...

introduction: bacterial infection of tooth pulp can progress into periapical diseases. root canal treatment has been established as the best treatment. in cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. materials & methods: in this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. all teeth showed...

OBJECTIVE The aim of this study was to compare the equivalent and effective doses of different digital radiographic methods (panoramic, lateral cephalometric and periapical) with cone-beam computed tomography (CBCT). METHODS Precalibrated thermoluminescent dosimeters were placed at 24 locations in an anthropomorphic phantom (Alderson Rando Phantom, Alderson Research Laboratories, New York, NY...

conclusions based on 8.2 mm cut-off point could differentiate 83% periapical granulomas and 79% radicular cysts from radiography images. background the distinction between radicular cysts and apical granulomas is important in treatment decision. objectives the current study aimed to differentiate these two lesions based on radiography images. results average size of radiography in periapical gr...
