fa Detection of vertical root fractures by cone-beam computerized tomography in endodontically treated teeth with fiber-resin and titanium posts: an in vitro study رادیولوژی دهان، فک و صورت Oral and Maxillofacial Radiology پژوهشي Research <p> <strong>Objective</strong></p><p>  The aim of this study was to assess the performance of 2 cone-beam computerized tomography (CBCT) systems for detecting vertical fractures in root-filled teeth with fiber-resin or titanium posts. </p><p> <strong>Study Design</strong></p><p>  CBCT images acquired with the use of Scanora 3D and i-CAT of roots with fiber-resin (n = 30) or titanium (n = 29) posts, before and after the induction of fractures, were assessed by 6 radiologists using Ondemand 3D software. Interobserver agreement was analyzed using kappa statistics. Sensitivity, specificity, accuracy, and positive and negative predictive values were compared with analysis of variance/Student-Newman-Keuls test. </p><p> <strong>Results</strong> </p><p> Interobserver agreement for fiber-resin posts ranged from 0.5 to 0.7 (Scanora 3D) and 0.35-0.76 (i-CAT). For titanium posts, ranged from 0.42 to 0.80 (Scanora 3D) and 0.31-0.73 (i-CAT). Higher sensitivity (0.85 P < .05) and negative predictive values (0.88 P < .001) were observed for i-CAT in roots with fiber-resin posts than with other combinations. </p><p> <strong>Conclusions</strong> </p><p> The diagnostic performance for detecting vertical fractures was higher for roots with fiber-resin than with titanium posts. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(12)00469-5/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1513&slc_lang=fa&sid=1 Rívea Inês Ferreira 10031947532846006918 10031947532846006918 Yes Department of Pediatric Dentistry and Orthodontics, University of São Paulo City, São Paulo, Brazil Golnosh Bahrami 10031947532846006919 10031947532846006919 No Prosthetic Dentistry, Department of Dentistry, Aarhus University, Aarhus, Denmark Flemming Isidor 10031947532846006920 10031947532846006920 No Prosthetic Dentistry, Department of Dentistry, Aarhus University, Aarhus, Denmark Ann Wenzel 10031947532846006921 10031947532846006921 No Oral Radiology, Department of Dentistry, Aarhus University, Aarhus, Denmark Francisco Haiter-Neto 10031947532846006922 10031947532846006922 No Department of Oral Diagnosis, Piracicaba Dental School, University of Campinas, Piracicaba, Brazil Francisco Carlos Groppo 10031947532846006923 10031947532846006923 No Department of Pharmacology, Anesthesiology and Therapeutics, Piracicaba Dental School, University of Campinas, Piracicaba, Brazil
