fa Visualization of the superior and inferior borders of the mandibular canal: a comparative study using digital panoramic radiographs and cross-sectional computed tomography images رادیولوژی دهان، فک و صورت Oral and Maxillofacial Radiology پژوهشي Research <p> <strong>Objective</strong></p><p>  To evaluate the visibility of the superior and inferior borders of mandibular canal using panoramic radiography (PR) and cross-sectional computed tomography (CT) images. </p><p> <strong>Study design</strong></p><p>  Digital panoramic images and cross-sectional CT images of 100 patients were evaluated. The mandibular canal was divided into 4 areas of equal width (1-4), from anterior to posterior. The visibility of the superior and inferior borders was assessed using a 5-point visibility scoring system, with lower scores for worse visibility. </p><p> <strong>Results</strong></p><p>  For both modalities, the superior border showed significantly lower score than the inferior border in all areas. For the superior border, areas 1, 2, and 3 all showed significantly lower scores than area 4 for PR, whereas only area 1 showed a lower score than area 4 for CT. </p><p> <strong>Conclusions</strong></p><p>  The visibility of the superior border was very poor on panoramic images. The use of cross-sectional CT images remarkably improved this poor visualization. </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)00007-2/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1592&slc_lang=fa&sid=1 Nahar Kamrun 10031947532846007377 10031947532846007377 No Oral and Maxillofacial Radiology, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan Akemi Tetsumura 10031947532846007378 10031947532846007378 Yes Oral and Maxillofacial Radiology, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan Yoshikazu Nomura 10031947532846007379 10031947532846007379 No Dental Hospital of Tokyo Medical and Dental University, Tokyo, Japan Satoshi Yamaguchi 10031947532846007380 10031947532846007380 No Oral and Maxillofacial Surgery, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan Otto Baba 10031947532846007381 10031947532846007381 No Biostructural Science, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan Shin Nakamura 10031947532846007382 10031947532846007382 No Oral and Maxillofacial Radiology, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan Hiroshi Watanabe 10031947532846007383 10031947532846007383 No Oral and Maxillofacial Radiology, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan Tohru Kurabayashi 10031947532846007384 10031947532846007384 No Oral and Maxillofacial Radiology, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan
