Perforations measuring 0.3 and 0.6\u2003mm in diameter and 0.15 and 0.3\u2003mm in depth, respectively, were made on the lingual root surfaces in thirty teeth, and four were used as controls. Next, teeth were mounted on an apparatus and radiographed at mesial, distal, and orthoradial angulations. CBCT images were also taken. The analysis of the intraoral radiographic and tomographic images was carried out by two experts using standardized scores. Data were then compared statistically. <jats:italic>Results<\/jats:italic>:\u00a0A strong agreement between the examiners was observed in both diagnosis methods, the intraoral radiographic (<jats:italic>r<\/jats:italic>\u2003=\u20030.93) and the tomographic analysis (<jats:italic>r<\/jats:italic>\u2003=\u20031.0). Tomography had higher statistically significant detection values than intraoral radiography (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05). In intraoral radiographs, the detection was significantly greater (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05) in the mandibular bicuspids, compared with their maxillary counterparts. The ability to detect 0.6\u2010mm perforations by intraoral radiography was significantly higher than that of 0.3\u2010mm perforations (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05). <jats:italic>Conclusion<\/jats:italic>:\u00a0Cone beam computed tomography showed better diagnostic ability compared with intraoral radiography, regardless of the tooth or the dimensions of the resorption evaluated.<\/jats:p>","DOI":"10.1111\/j.1600-9657.2011.01113.x","type":"journal-article","created":{"date-parts":[[2012,1,11]],"date-time":"2012-01-11T09:19:21Z","timestamp":1326273561000},"page":"268-272","source":"Crossref","is-referenced-by-count":55,"title":["Comparative
