Abstract:

Diagnosis of horizontal root fractures (HRF) base on clinical andradiographic documents. The aim of this study was to compare the diagnostic accuracy of digital periapical graphs (PSP) with different angulations in different location and Conebeam Computed Tomography (CBCT) in the detection of HFR in central and lateralmaxillary incisors. For this experimental study, 60 human central and lateralmaxillary incisors were selected and were divided in 4 groups and were numbered. In the first group root fractures were created by using mechanical force in the apical third, in the second group were in the middle and the third group were in the cervical part`s of roots, the last group were considered as control group with out any fractures. The two fragment from each tooth were relocated with super glue. Then, radiographic image of all the teeth were taken using digital PSP and CBCT methods. Afterwards, two oral and maxillofacial radiologists assessed the image separately, the data were subjected to specificity and sensitivity for each radiographic technique. The Kappa statistics was used for assessing the agreement between observers. Significant level was considred as p<0.05. CBCT method has higher specificity and sensitivity in the detection of HRF compared to PSP. Kappa value for inter-observer agreement in HRF is equaled /.89 for CBCT and /.72/5 for PA. CBCT, out performed the PSP method in detecting simulated HRF. CBCT should be consider as reliable imaging modality of choice for the diagnosis of HRF.
