Belma Muhamedagic, Lejla Muhamedagic Faculty of Medicine, University of Sarajevo, Bosnia and Herzegovina ography-RVG, Trophy Radiologie, Croissy Beaubourg, France [now Trophy, A Kodak Company, Rochester, N.Y.]). RVG is modern diagnostic method based on use of digital roentgen. Principle is use of so called CCD chip in RVG sensor (Figure 1) that put in patient’s mouth (3). The first dental digit...
introduction: the aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.methods: thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. after access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. wi...
introduction: the purpose of this in vitro study was to compare the accuracy of the new electronic apex locator raypex5 with radiography for working length determination of straight and curved root canals. materials and methods: twenty straight and single canals of maxillary central teeth and twenty curved mesiobuccal canals of mandibular molar teeth were used. access cavities were prepared and...
conclusion dt-sfp can improve the detection of relatively early bone abnormalities in acetabular and proximal femur compared with conventional radiography. dt-sfp can also observe the abnormal impact between acetabular and proximal femur. patients and methods ninety-four consecutive patients with discomfort around the hip joint underwent dt-sfp and conventional radiography. the imaging features...
introduction: the purpose of this in vitro study was to compare the accuracy of working length determination using the apex locator versus conventional radiography in c-shaped canals. methods and materials: after confirming the actual c-shaped anatomy using cone-beam computed tomography (cbct), 22 extracted c-shaped mandibular second molars were selected and decoronated at the cemento-enamel ju...
Background and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects. Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...

introduction: success in endodontic treatment depends on various factors. among the most important factors, appropriate preparation of the root canal system and keeping periapical region intact as much as possible could be mentioned. these are achieved by determining the penetration depth of the instruments into the canal i.e. the working length. several methods are introduced for working lengt...
