After thorough scaling and root surface conditioning with 10% tetracycline\u2010HCl, a trapezoidal mucoperiosteal flap was prepared. A customized barrier was applied to cover the defect. Barriers adhered directly to tooth and bone and no sutures were used. The barrier was subsequently covered by a coronally positioned flap. Assessments of probing depths were performed by means of a controlled\u2010force electronic probe, and recession was determined on stone models with a digital caliper at baseline and 12 months following therapy.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Eight barriers showed limited exposure (1 to 2 mm) with minimal signs of gingival inflammation between 2 and 6 weeks following surgery. Comparing baseline measurements with outcomes at 12 months, significant root coverage and probing attachment gain were observed (\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.0001, paired\n                    <jats:italic>t<\/jats:italic>\n                    test). Mean gingival recession was reduced to 0.4 \u00b1 0.5 mm, corresponding to a mean root coverage of 91.9%, and overall attachment gains amounted to 4.2 mm. A significant gain of keratinized tissue was found (2.9 \u00b1 0.7 mm), and mean probing depths were slightly reduced from 2.2 to 1.7 mm.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    The results of this study indicate favorable outcomes after using a new bioabsorbable barrier material for root coverage in recession\u2010type defects.\n                    <jats:italic>J Periodontol 2000;71:1433\u20101440.<\/jats:italic>\n                  <\/jats:p>","DOI":"10.1902\/jop.2000.71.9.1433","type":"journal-article","created":{"date-parts":[[2005,2,2]],"date-time":"2005-02-02T06:37:42Z","timestamp":1107326262000},"page":"1433-1440","source":"Crossref","is-referenced-by-count":13,"title":["Evaluation of a New Bioabsorbable Barrier for Recession Therapy: A Feasibility Study"],"prefix":"10.1002","volume":"71","author":[{"given":"S\u2298ren","family":"Jepsen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernd","family":"Heinz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehrdad Arjomand","family":"Kermanie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karin","family":"Jepsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2000,9]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.2000.71.9.1433","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:05:43Z","timestamp":1760871943000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.2000.71.9.1433"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,9]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2000,9]]}},"alternative-id":["10.1902\/jop.2000.71.9.1433"],"URL":"https:\/\/doi.org\/10.1902\/jop.2000.71.9.1433","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"value":"0022-3492","type":"print"},{"value":"1943-3670","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,9]]}}}
