“…Infections/inflammatory processes within the jawbone – in the immediate vicinity of an integrating implant – such as periapical lesions (79, 85) around neighboring teeth, cysts (which are often underestimated on radiographs) (24, 86), root remnants, or foreign bodies (e.g. endodontic material) (19), seriously interfere with osseointegration.…”

“…Nevertheless, periapical lesions confined to cancellous bone could be detected radiographically using pixel values using one of the tools of the digital image, the histogram 2 . Only a few studies employing animal models 3,7,8 or human biopsies 10,21,23 have compared the diagnostic and quantifying accuracy of radiographs to the gold standard represented by the histology. The aim of this study was to induce periapical disease in rats to assess the pixel values in different experimental periods to evaluate the bone loss progression.…”

ObjectiveThis study evaluated experimentally-induced periapical bone loss sites using digital radiographic and histopathologic parameters. Material and MethodsTwenty-seven Wistar rats were submitted to coronal opening of their mandibular right first molars. They were radiographed at 2, 15 and 30 days after the operative procedure by two digital radiographic storage phosphor plates (Digora®). The images were analyzed by creating a region of interest at the periapical region of each tooth (ImageJ) and registering the corresponding pixel values. After the sacrifice, the specimens were submitted to microscopic analysis in order to confirm the pulpal and periapical status of the tooth. ResultsThere was significant statistically difference between the control and test sides in all the experimental periods regarding the pixel values (two-way ANOVA; p<0.05). ConclusionsThe microscopic analysis proved that a periapical disease development occurred during the experimental periods with an evolution from pulpal necrosis to periapical bone resorption.

“…Some studies even report that (direct) digital radiography provides equivalent (13,14) or improved (15) diagnostic results compared with conventional film. Software to process digital images continues to become more and more sophisticated and user-friendly.…”
