Introduction. Does high-resolution visualization of microcalcifications improve diagnostic reliability? Method. X-rays were taken of mamma specimens with microcalcifications in 32 patients (10 malignant; 22 benign) using conventional radiography (12 Lp/mm) and high-resolution radiography (2000 Lp/mm). Histological sections were subsequently prepared and correlated to the microradiographic image...
introduction: inappropriate condensation of gutta-percha or improper use of sealer can lead to voids in root canal filling material and consequent failure of the treatment. timely detection of voids within root canal filling may prevent complications. in this study, we compared the accuracy of digital and conventional radiograph for detecting voids within root canal fillings . materials & metho...
Introduction: External root resorption is a clinical problem that often cannot be detected clinically. Thus, radiography plays a crucial role in its diagnosis. However, optimal radiographic quality with minimal radiation exposure {2.1 [EN] Verify English word/phrase choice} is an important factor in selecting the appropriate radiographic technique. The aim of this study was the comparison of ac...
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...
OBJECTIVE The objective of this study was to assess the impact of filmless operation and computed radiography on technologists' examination times compared with conventional film-based operation and film-screen radiography. CONCLUSION Compared with conventional film-screen operation, filmless operation using computed radiography was associated with a significant decrease in technologist examin...
