Unfortunately, there is only a limited amount of information available on the long\u2010term results of root coverage procedures. The goal of this study was to evaluate the short\u2010term and long\u2010term root coverage results obtained with an acellular dermal matrix and a subepithelial graft.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    An\n                    <jats:italic>a priori<\/jats:italic>\n                    power analysis was done to determine that 25 was an adequate sample size for each group in this study. Twenty\u2010five patients treated with either an acellular dermal matrix or a subepithelial graft for root coverage were included in this study. The short\u2010term (mean 12.3 to 13.2 weeks) and long\u2010term (mean 48.1 to 49.2 months) results were compared. Additionally, various factors were evaluated to determine whether they could affect the results. This study was a retrospective study of patients in a fee\u2010for\u2010service private periodontal practice. The patients were not randomly assigned to treatment groups.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    The mean root coverages for the short\u2010term acellular dermal matrix (93.4%), short\u2010term subepithelial graft (96.6%), and long\u2010term subepithelial graft (97.0%) were statistically similar. All three were statistically greater than the long\u2010term acellular dermal matrix mean root coverage (65.8%). Similar results were noted in the change in recession. There were smaller probing reductions and less of an increase in keratinized tissue with the acellular dermal matrix than the subepithelial graft. None of the factors evaluated resulted in the acellular dermal graft having a statistically significant better result than the subepithelial graft. However, in long\u2010term cases where multiple defects were treated with an acellular dermal matrix, the mean root coverage (70.8%) was greater than the mean root coverage in long\u2010term cases where a single defect was treated with an acellular dermal matrix (50.0%).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    The mean results with the subepithelial graft held up with time better than the mean results with an acellular dermal matrix. However, the results were not universal. In 32.0% of the cases treated with an acellular dermal matrix, the results improved or remained stable with time.\n                    <jats:italic>J Periodontol 2004;75:734\u2010743<\/jats:italic>\n                    .\n                  <\/jats:p>","DOI":"10.1902\/jop.2004.75.5.734","type":"journal-article","created":{"date-parts":[[2005,2,2]],"date-time":"2005-02-02T07:54:57Z","timestamp":1107330897000},"page":"734-743","source":"Crossref","is-referenced-by-count":88,"title":["A Short\u2010Term and Long\u2010Term Comparison of Root Coverage With an Acellular Dermal Matrix and a Subepithelial Graft"],"prefix":"10.1002","volume":"75","author":[{"given":"Randall J.","family":"Harris","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,5]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.2004.75.5.734","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:56:16Z","timestamp":1760874976000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.2004.75.5.734"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,5]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2004,5]]}},"alternative-id":["10.1902\/jop.2004.75.5.734"],"URL":"https:\/\/doi.org\/10.1902\/jop.2004.75.5.734","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"value":"0022-3492","type":"print"},{"value":"1943-3670","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,5]]}}}
