Four classes (A+, A\u2212, B+, and B\u2212) were identified on the basis of these variables. To validate the classification three different calibrated examiners applied the proposed classification system to 46 gingival recessions and \u03ba statistics were performed. The classification was used on 1,010 gingival recessions from 353 patients to examine the distribution of the four classes.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    The \u03ba statistics for intrarater agreement ranged from 0.74 to 0.95 (almost perfect agreement), whereas interrater agreement ranged from 0.26 to 0.59 (moderate agreement). Out of 1,010 exposed root surfaces associated with gingival recession, 144 showed an identifiable CEJ associated with a root surface defect (Class A+, 14%); 469 an identifiable CEJ without any associated step (Class A\u2212, 46%); 244 an unidentifiable CEJ with a step (Class B+, 24%); and 153 an unidentifiable CEJ without any associated step (Class B\u2212, 15%).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    The proposed classification describes the dental surface defects that are of paramount importance in diagnosing gingival recession areas.\n                  <\/jats:p>","DOI":"10.1902\/jop.2010.090631","type":"journal-article","created":{"date-parts":[[2010,4,9]],"date-time":"2010-04-09T11:43:23Z","timestamp":1270813403000},"page":"885-890","source":"Crossref","is-referenced-by-count":129,"title":["Classification of Dental Surface Defects in Areas of Gingival Recession"],"prefix":"10.1002","volume":"81","author":[{"given":"Giovanpaolo","family":"Pini\u2010Prato","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Debora","family":"Franceschi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Cairo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele","family":"Nieri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Rotundo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,6]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"44","volume-title":"Glossary of Periodontal Terms","author":"American Academy of Periodontology","year":"2001"},{"key":"e_1_2_7_3_1","first-page":"8","article-title":"A classification of marginal tissue recession","volume":"5","author":"Miller PD","year":"1985","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2006.050038"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1987.58.10.674"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0757.1993.tb00213.x"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2008.01244.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2009.080565"},{"key":"e_1_2_7_9_1","first-page":"57","article-title":"The treatment of gingival recession associated with deep corono\u2010radicular abrasions (CEJ step) \u2013 A case series","volume":"1","author":"Pini\u2010Prato G","year":"2004","journal-title":"Perio\u2013Periodontal Practices Today"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1999.70.9.1064"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2005.76.5.713"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2008.01346.x"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2009.090041"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.2307\/2529310"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1999.70.9.1077"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2006.10.038"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0b013e31816ae3ec"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2008.01348.x"}],"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.2010.090631","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:11:30Z","timestamp":1760872290000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.2010.090631"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,6]]},"references-count":17,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2010,6]]}},"alternative-id":["10.1902\/jop.2010.090631"],"URL":"https:\/\/doi.org\/10.1902\/jop.2010.090631","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"value":"0022-3492","type":"print"},{"value":"1943-3670","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,6]]}}}
