【 摘 要 】

Introduction: Detection of root fracture is challenging bothclinically and radiographically. Root fractures occur in differentplanes with unpredictable presentations.Aim: The aim of the study was to evaluate the diagnosticaccuracy of selected digital image enhancement tools in thedetection of horizontal Root Fracture (RF).Materials and Methods: Fifty three roots, of single and multirooted teeth, in eight dentate human cadaver mandibles wereselected for this study. Following minimally traumatic extractionof the teeth, horizontal fractures were induced in 23 roots andremounted in the empty sockets of their respective humandry mandibles. The remaining teeth with no fractures wereused as the control group. Twenty two periapical radiographswere obtained by using the paralleling technique and usingComplementary Metal Oxide Semiconductor (CMOS). ImageJ software was used to enhance the original images with theInversion (IN), Histogram-Equalization (EQ) and Polynomial(Poly) tools. A total of 88 periapical images (original and threeenhanced images) were reviewed independently by three Oraland Maxillofacial Radiologists and two Endodontists. ReceiverOperating Characteristic (ROC) curve analysis was used toevaluate the accuracy of fracture detection and the kappastatistic was used to assess agreement among reviewers.Results: The diagnostic accuracy for one of the observerswas significantly different in detection of RF with only EQenhancement tool. Sensitivity and specificity were notsignificantly different. Interobserver agreement showed nosignificant difference between imaging methods. Intra-observeragreement was high to moderate.Conclusion: There was no significant difference between thedifferent imaging modalities. No statistical difference for theagreement was found among or between the endodontists andradiologists in this study.
