fa Diagnostic accuracy of charge-coupled device sensor and photostimulable phosphor plate receptor in the detection of external root resorption in vitro رادیولوژی دهان، فک و صورت Oral and Maxillofacial Radiology پژوهشي Research <b> Background and aims.</b> Early diagnosis of external root resorption is important for accurate treatment. The purpose of this study was to compare the efficacy of a charge-coupled device (CCD) sensor and a photostimulable phosphor (PSP) plate receptor in the diagnosis of artificial external root resorption. <div><b>Materials and methods.</b> In this diagnostic in-vitro study, 40 maxillary incisors were mounted in a segment of dry bone and preliminary radiographs were obtained using CCD and PSP sensors. Artificial resorption cavities were produced on the middle-third in half of the samples and on the cervical-third in the other half on the buccal root surfaces. Radiographs were repeated and images were evaluated. Data were statistically analyzed using chi-square and diagnostic tests. </div><div><b>Results.</b> There were no significant differences between the two sensors in the sensitivity (P =0.08 and 0.06) and specificity (P =0.13) for the diagnosis of resorption in both root areas. The overall accuracy of CCD was higher than PSP sensor however, the difference was not statistically significance (P >0.05). </div><div><b>Conclusion</b>. CCD and PSP sensors chosen for the present study produced similar results in diagnosing simulated external root resorption.</div><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Journal of Dental Research, Dental Clinics, Dental Prospects </p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://dentistry.tbzmed.ac.ir/joddd/index.php/joddd/article/view/1218" target="_blank"><font color="#0000ff">Full Text</font></a></p> Dental radiography, digital radiography, root resorption 0 0 http://idai.ir/browse.php?a_code=A-10-32-3307&slc_lang=fa&sid=1 Shirin Sakhdari sh_sakhdari@dentaliau.ac.ir 100319475328460015231 100319475328460015231 Yes Department of Oral & Maxillofacial Radiology, Maxillofacial Research Center,Islamic Azad University, Dental Branch, Tehran- Iran Zohreh Khalilak 100319475328460015232 100319475328460015232 No Department of Endodontics, Islamic Azad University, Dental Branch, Tehran- Iran Elham Najafi 100319475328460015233 100319475328460015233 No Department of Endodontics, Faculty of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran Rezvaneh Cheraghi 100319475328460015234 100319475328460015234 No Department of Epidemiology and Reproductive Health at Reproductive Epidemiology Research Center, Royan Institute for Reproduc- tive Biomedicine, ACECR, Tehran, Iran
