OBJECTIVE Our aim was to compare the Accu-I-Tomo (3DX), the Digora Optime image plate system and F-speed film in detecting chemically created apical lesions. METHODS Lesions were created by applying perchloric acid apical to extracted teeth in jaw specimens for 1, 1.5 or 2 h. After being repositioned, teeth were radiographed with Accu-I-Tomo limited cone beam CT (LCBCT), Digora Optime storage...

Objectives: This study aimed to compare the efficacy of panoramic radiography and the buccal object rule in intraoral periapical radiography for localization of impacted maxillary canine teeth. Methods: A total of 20 panoramic radiographs depicting 28 displaced maxillary canines were evaluated. The ratio of the mesiodistal width of the impacted canine to the mesiodistal width of the...

X‐rays were discovered in 1895 by Wilhelm Roentgen. Digital radiology has overtaken conventional screen‐film radiography since it was introduced in the mid‐1980s.[1] Digital imaging uses sensor of solid‐state, and information is presented and stored as an image using a computer. The dawn of the digital era in dental radiography came in 1987 with the first digital radiography system called radio...

INTRODUCTION The aim of this study was to compare the diagnostic value of cone-beam computed tomography (CBCT) and periapical (PA) radiography in detecting internal root resorption. METHODS AND MATERIALS Eighty single rooted human teeth with visible pulps in PA radiography were split mesiodistally along the coronal plane. Internal resorption like lesions were created in three areas (cervical,...

Maurizio Innocenti, MD, Servizio Nefrologia e Dialisi, Ospedale Umberto 1°, Via del Medolo, 2, I-25100 Brescia (Italy) Dear Sir, Maxwell et al. [1] compared the sensitivity of maxillomandibular and hands versus skeletal roentgenograms as screening techniques for evaluating bone disease in uremic patients. They examined the four following radiological findings xortical or medullary bone loss, su...

This article describes and discusses a method to determine root curvature radius by using cone-beam computed tomography (CBCT). The severity of root canal curvature is essential to select instrument and instrumentation technique. The diagnosis and planning of root canal treatment have traditionally been made based on periapical radiography. However, the higher accuracy of CBCT images to identif...

INTRODUCTION One of the common findings encountered by the clinician at the end of orthodontic treatment is the apical root resorption. Root resorption occurs to various degrees. A severe form of root resorption is characterized by shortening of root for more than 4 mm or more than one-third of the total tooth length. A low incidence rate of resorption is observed based on radiographic findings...

The NDT community discusses about effective film replacement by Computed Radiography (CR) and Digital Detector Arrays (DDA), also known as flat panel detectors, since more than 10 years. Several standards were published by CEN, ASTM and ASME to support the application of phosphor imaging plates in lieu of X-ray film in the year 2005. The European Community funds the project FilmFree, which supp...
