Purpose: Root fracture is a clinical problem which often is difficult to detect and diagnose. As the root fracture detection is based on demonstration of a fracture line or lines, radiographic examination is important. The aim of this study was to compare diagnostic efficacy of direct digital radiography with conventional radiography for detecting experimental root fractures. Materials & Method...

background: the most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate.   objective: the present study is aimed at initially establishing a baseline for local-reference dose level in mazandaran, iran in 12 projections of th...

introduction proper cleaning and shaping of the root canal system is one of the most important aspects of endodontic therapy. to estimate the canal length before instrumentation in endodontic treatment, traditionally, conventional radiographic techniques and, recently, direct digital radiography (ddr) are applied. the application of computer technology in radiography has allowed less exposure t...

OBJECTIVES To compare the differences between conventional radiography and digital computerized radiography (CR) in patients presenting to the emergency department. METHODS The study enrolled consecutive patients presenting to the emergency department who needed chest radiography. Quality score of the radiogram was assessed with visual analogue score (VAS-100 mm), measured in terms of millime...

conclusion for the identification of nasal bone fractures, ct was significantly superior to conventional radiography. although a staff radiologist showed better values in the identification of nasal bone fracture and differentiation between depressed and non-depressed fractures than a trainee, there was no statistically significant difference in the interpretation of conventional radiography an...

successful endodontic therapy depends on adequate mechanical and chemical debridement of the canal which requires knowledge of the canal morphology. conventional radiography has been used to evaluate the canal type; however, direct digital radiography has recently been practiced for this purpose due to the shortcomings of conventional radiography. the aim of the present study was to compare the...

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...
