Before the advent of OPG and CBCT; Intraoral periapical radiography was mainstay of dental imaging since years. CBCT was rst adapted for potential clinical use in 1982 at the Mayo Clinic Biodynamics Research Laboratory. This technique is a recent development and is found to be more efcient and economical than conventional tomography or CT in oral diagnosis. CBCT allows better 3D visualisation...

Detection of iatrogenic root perforation during post-space preparation especially in labiolingual plane can be challenging due to the two-dimensional nature of conventional radiography; this can be even more challenging if the cemented post is radiolucent. Cone-beam computed tomography (CBCT) scans were shown to be a valuable diagnostic aid in diagnosis of such cases. However, in this case, the...

background radiographs play an integral role in the assessment of periodontal disease. in recent years, advent of digital imaging has revolutionized radiology in dentistry. patients and methods in this diagnostic accuracy study, 48 inter proximal surfaces were evaluated in eight patients. these patients had alveolar bone loss in anterior regions because of periodontitis. intraoral (parallel per...

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. W...

BACKGROUND AND AIMS Radiography is used to diagnose the demineralization process and carious lesions; however, conventional radiography and direct digital images do not show these lesions when the amount of demineralization is less than 40%. Digital subtraction radiography has recently been used to improve the diagnostic quality of these le-sions. The purpose of this study was to compare the ca...

Computer-aided diagnosis (CAD) has become one of the major research subjects in medical imaging and diagnostic radiology. Many different CAD schemes are being developed for use in the detection and/or characterization of various lesions found through various types of medical imaging. These imaging technologies employ conventional projection radiography, computed tomography, magnetic resonance i...

Eighty-six osteolytic lesions of the rib cage were examined by means of conventional radiography and ultrasonography. The ultrasonographic criteria of osteolysis are described. Only 1 rib metastasis was missed by ultrasonography while 13 lesions were not detected by x-ray film. Of 63 ultrasonographically guided biopsies, 62 resulted in the final diagnosis; complications were not observed. The r...

In recent years, Latin American countries have used their economic growth to improve their technologies applied to Healthcare. Both the private and the public sector are aware that the only way to improve the quality of life of people is through Health, Food and Education. This economic recovery is reflected in a steady and sustained increase in Healthcare spending, and together with the depend...
