The aim of the present study was to evaluate the clinical efficacy of a coronally advanced flap procedure with the additional use of enamel matrix protein derivative (EMD) to treat gingival recession and to compare it to the subpedicle connective tissue graft procedure (CTG).<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> The study was conducted in six different periodontal clinics. Miller Class I or II buccal recession type defects in the anterior or premolar teeth were treated in 70 consecutive patients, 30 with EMD and 40 with CTG. At baseline and 6 and 12 months post\u2010surgical treatment, vertical recession defect, defined as the distance from cemento\u2010enamel junction to gingival margin; width of keratinized tissue; and probing depth were recorded and the percentage of coverage of the original defect was calculated. Statistical analyses consisted of t\u2010test, analysis of variance, and analysis of covariance<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> At 6 months, percent of root coverage was 77.4% \u00b1 11.92% in EMD and 84.1% \u00b1 11.97% in CTG (statistically significant at <jats:italic>P<\/jats:italic> = 0.024). At 12 months, percent of root coverage in EMD was 71.7% \u00b1 16.14% and 87.0% \u00b1 12.22% in CTG; again, differences between groups were statistically significant (<jats:italic>P<\/jats:italic> &lt;0.001). Differences between the 6\u2010 and 12\u2010month vertical recession defect and percent of root coverage recordings within each group were also statistically significant.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> The connective tissue graft procedure was superior to the coronally positioned flap with the addition of enamel matrix proteins derivative in percentage of coverage and increase in width of keratinized tissue. The EMD procedure is a predictable treatment for root coverage that is relatively easy to perform and presents low patient morbidity, and is appropriate especially where a substantial increase in the width of keratinized tissue is not of prime importance. <jats:italic>J Periodontol 2004;75:600\u2010607<\/jats:italic>.<\/jats:p>","DOI":"10.1902\/jop.2004.75.4.600","type":"journal-article","created":{"date-parts":[[2005,2,2]],"date-time":"2005-02-02T07:55:45Z","timestamp":1107330945000},"page":"600-607","source":"Crossref","is-referenced-by-count":53,"title":["A Multicenter Comparative Study of Two Root Coverage Procedures: Coronally Advanced Flap With Addition of Enamel Matrix Proteins and Subpedicle Connective Tissue Graft"],"prefix":"10.1002","volume":"75","author":[{"given":"Carlos E.","family":"Nemcovsky","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zvi","family":"Artzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haim","family":"Tal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Avital","family":"Kozlovsky","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ofer","family":"Moses","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,4]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.2004.75.4.600","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T13:40:47Z","timestamp":1760881247000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.2004.75.4.600"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,4]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2004,4]]}},"alternative-id":["10.1902\/jop.2004.75.4.600"],"URL":"https:\/\/doi.org\/10.1902\/jop.2004.75.4.600","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"type":"print","value":"0022-3492"},{"type":"electronic","value":"1943-3670"}],"subject":[],"published":{"date-parts":[[2004,4]]}}}
