Among tooth resorption types described for human teeth, the AVDC classification method was totally applicable (100%) in 17 teeth with external surface resorption, 21 teeth with external replacement resorption, and 736 teeth with external cervical root surface resorption, but it was applicable in only 56 of 121 (46.3%) teeth with external inflammatory resorption and none of the teeth with internal resorption.<\/jats:p>\n<jats:p><jats:bold>Conclusions and Clinical Relevance<\/jats:bold>\u2014The AVDC classification method was useful to describe the extent of tooth resorption in dogs, but it did not reflect the radiographic patterns and location of lesions. The AVDC classification method was applicable in some, but not all, of the teeth with various resorption types in dogs. The AVDC classification method could be adapted best to lesions that have radiographic patterns of external replacement resorption and external cervical root surface resorption.<\/jats:p>","DOI":"10.2460\/ajvr.71.7.794","type":"journal-article","created":{"date-parts":[[2010,7,1]],"date-time":"2010-07-01T20:33:46Z","timestamp":1278016426000},"page":"794-798","source":"Crossref","is-referenced-by-count":19,"title":["Radiographic evaluation of the classification of the extent of tooth resorption in dogs"],"prefix":"10.2460","volume":"71","author":[{"given":"Santiago","family":"Peralta","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank J.
