OBJECTIVE The aim of this study was to compare the accuracy of endodontic file lengths after application of various image enhancement modalities. STUDY DESIGN Endodontic files of three different ISO sizes were inserted in 20 single-rooted extracted permanent mandibular premolar teeth and standardized images were obtained. Original digital images were then(More)
The aim of the study was to evaluate the effect of two lossy image compression methods on fractal dimension (FD) calculation. Ten periapical images of the posterior teeth with no restorations or previous root canal therapy were obtained using storage phosphor plates and were saved in TIF format. Then, all images were compressed with lossy JPEG and JPEG2000(More)
The aim of this study was to evaluate the effect of exposure time and image resolution on fractal dimension (FD) of periapical bone on images obtained using a storage phosphor plate (SPP) system. Periapical images of premolar and molar teeth on both sides of ten dry human mandibles were obtained with Digora Optime (Soredex Corp., Helsinki, Finland) SPP(More)
UNLABELLED This in vitro study evaluated the validity of the decision to replace of a restoration based upon the radiolucent zone beneath a resin composite. MATERIALS AND METHODS Class II cavities were prepared on the approximal surfaces of 40 molars. The teeth were divided into four groups. Clearfil SE Bond, PQ1 or Single Bond was applied in the(More)
OBJECTIVE To test the efficacy of conventional radiometry with indirect digital image analysis in the assessment of the relative radiopacity of dental cements used as liners or bases compared to human enamel and dentin. METHOD AND MATERIALS Disks of 15 different dental cements, 5 mm in diameter and 2 mm thick, were exposed to radiation together with(More)
