Thus, the aims of this study are two\u2010fold: 1) to evaluate the long\u2010term outcomes following CAF in the treatment of gingival recession (GR); and 2) to explore the influence of several tooth\/patient\u2010related factors on the stability of gingival margin at 5, 10, and 20 years after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Ninety\u2010four patients with 97 GR (73 Miller`s Class I and 24 Miller's Class III) were treated with CAF in a private practice between 1984 and 1996. Recession depth (RD), probing depth (PD), keratinized tissue (KT) width and patient\/tooth\u2010associated variables were recorded for each GR at baseline, 1 year, 5 years, 10 years, 15 years and 20 years after surgery. Parametric, non\u2010parametric, and logistic regression statistics were used throughout the study<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 72 patients with 72 GR were available for analysis at the 20\u2010year follow\u2010up examination (final patients\u2019 dropout rate\u00a0=\u00a023.4%). Statistically significant improvements were found for RD in all evaluations (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.05). Little more than a half (56%) of the sites treated with CAF did not display RD changes between the short\u2010term (i.e., 1 year) and long\u2010term (i.e., 20 years) examinations. Overall, mean root coverage (MRC) decreased from 68.59% to 56.11%. The achievement of complete root coverage (CRC) 1 year after treatment was associated to GR not presenting interdental tissue loss (<jats:italic>P\u00a0<\/jats:italic>=\u00a00.001), the root condition (i.e., lack of non\u2010carious cervical lesion [step] \u2013 <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001), an attached KT band\u00a0\u2265\u00a02\u00a0mm (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.019), and baseline RD (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.020). GR recurrence seemed to be influenced by age, RD at 1\u2010year follow\u2010up, sites displaying an attached KT\u00a0&lt;\u00a02\u00a0mm and interdental tissue loss.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The aging process, the condition of the interdental periodontal tissue, and the presence of an attached KT band\u00a0&lt;\u00a02\u00a0mm seem to be negative factors influencing the stability of the gingival margin during the 20\u2010year observation period.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jper.17-0379","type":"journal-article","created":{"date-parts":[[2018,2,12]],"date-time":"2018-02-12T02:58:37Z","timestamp":1518404317000},"page":"265-274","source":"Crossref","is-referenced-by-count":62,"title":["Long\u2010term evaluation (20 years) of the outcomes of coronally advanced flap in the treatment of single recession\u2010type defects"],"prefix":"10.1002","volume":"89","author":[{"given":"Giovan Paolo","family":"Pini Prato","sequence":"first","affiliation":[{"name":"Tuscany Academy of Dental Research (ATRO)  Florence Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Magnani","sequence":"additional","affiliation":[{"name":"Private practice  Florence Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leandro","family":"Chambrone","sequence":"additional","affiliation":[{"name":"Unit of Basic Oral Investigation (UIBO) School of Dentistry El Bosque University, Bogota, Colombia;
