fa Comparison of images from digital intraoral receptors and cone beam computed tomography scanning for detection of voids in root canal fillings: an in vitro study using micro-computed tomography as validation رادیولوژی دهان، فک و صورت Oral and Maxillofacial Radiology پژوهشي Research <p> <strong>Objective</strong></p><p>  To compare the diagnostic value of six intraoral digital receptors and a cone beam computed tomography scanning system for detection of voids in root fillings. </p><p> <strong>Methods</strong> </p><p> Sixty-seven root-filled roots with oval and ribbon-shaped canals were included. Three standardized radiographic examinations were performed for each root with six intraoral digital receptors. Further, the roots were examined using CBCT. Four observers measured the extension of voids in all images. The true extension of voids was recorded in cross-sectional images from micro-computed tomography scans (micro-CT). The proportion of voids observed in the radiographic image validated against micro-CT was calculated for each system. </p><p> <strong>Results</strong></p><p>  All intraoral receptors underestimated the extension of voids, and few false positives were recorded. CBCT resulted in a higher proportion of correctly observed voids, but with several false-positive recordings. </p><p> <strong>Conclusions</strong></p><p>  The diagnostic value differed little among the six intraoral systems. CBCT overestimated in many cases the proportion of voids in root fillings. </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(13)00144-2/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1641&slc_lang=fa&sid=1 Line Møller 10031947532846007666 10031947532846007666 No Section for Dental Pathology, Operative Dentistry and Endodontics, Department of Dentistry, Health, Aarhus University, Denmark Ann Wenzel 10031947532846007667 10031947532846007667 No Section for Oral Radiology, Department of Dentistry, Health, Aarhus University, Denmark Anne Mette Wegge-Larsen 10031947532846007668 10031947532846007668 No The Danish Army Health Services, Royal Dragoons, Holstebro, Denmark Ming Ding 10031947532846007669 10031947532846007669 No Department of Orthopaedics and Traumatology, Institute of Clinical Research, Odense University Hospital, University of Southern Denmark, Denmark Michael Væth 10031947532846007670 10031947532846007670 No Section of Biostatistics, Department of Public Health, Health, Aarhus University, Denmark Edgar Hirsch 10031947532846007671 10031947532846007671 No Department of Dentomaxillofacial Radiology, School of Dentistry, Leipzig University, Germany Lise-Lotte Kirkevang 10031947532846007672 10031947532846007672 Yes Department of Endodontology, Institute of Clinical Odontology, Faculty of Dentistry, University of Oslo, Norway
