PACE, Sandra Regina Boarin  and  HABITANTE, Sandra Márcia. Comparative analysis of the visualization of small files using digital and conventional radiography. J. Appl. Oral Sci. [online]. 2005, vol.13, n.1, pp.20-23. ISSN 1678-7757.

The present work was designed to carry out a comparative analysis of the visualization of small files using digital and conventional radiographs. Forty maxillary molars inserted in human skulls were used; Maillefer K-files #06, #08, #10 and #15 were inserted in the mesiobuccal canals and measured at 0.5mm beyond and 1.5mm before the tip with 0.5-mm intervals, in order to allow five professionals to observe whether the files were at the limit, before or beyond the foramen when visualized on conventional radiographs taken on Insight Kodak film (Eastman Kodak, Rochester, NY, USA) and with the RVG digital system (Trophy). Based on the results obtained, the conclusions were: with the two systems it was possible to visualize #06 K-files in nearly 60% of the evaluated cases; for the others, #08, #10 and #15 K-files, visualization was higher with both radiographic systems, achieving 82% of correct visualization for #15 K-files with the conventional system. The differences between the results of the two systems studied - conventional (Insight film, Kodak F-speed) and last generation digital (RVG - Trophy) radiographs - were not statistically significant according to the Student's t test.
