However, in some situations most clinicians would agree that surgical procedures to increase the amount of keratinized tissue without root coverage are indicated. In this study, 3 surgical procedures were compared in their ability to increase the width of keratinized tissue. They are: the epithelized autogenous masticatory mucosa graft (free gingival graft), autogenous predominately connective tissue graft (connective tissue graft), and acellular dermal matrix.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Forty\u2010five patients referred for treatment of areas with inadequate keratinized tissue were randomly assigned into 1 of 3 groups of 15 each. Each group was treated with 1 of the 3 surgical procedures to increase the width of keratinized tissue. The width of keratinized tissue pre\u2010 and postsurgery was evaluated.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> All 3 groups started with a similar width of keratinized tissue. All of the surgical procedures resulted in a statistically significant increase in the width of keratinized tissue: free gingival graft, 4.1 mm; connective tissue graft, 3.6 mm; and acellular dermal matrix, 4.1 mm.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> A statistically significant increase in the amount of keratinized tissue was obtained with all 3 surgical procedures evaluated. <jats:italic>J Periodontol 2001;72:932\u2010938.<\/jats:italic><\/jats:p>","DOI":"10.1902\/jop.2001.72.7.932","type":"journal-article","created":{"date-parts":[[2005,2,2]],"date-time":"2005-02-02T07:00:05Z","timestamp":1107327605000},"page":"932-938","source":"Crossref","is-referenced-by-count":50,"title":["Clinical Evaluation of 3 Techniques to Augment Keratinized Tissue Without Root Coverage"],"prefix":"10.1002","volume":"72","author":[{"given":"Randall J.","family":"Harris","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2001,7]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.2001.72.7.932","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T08:34:21Z","timestamp":1760862861000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.2001.72.7.932"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,7]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2001,7]]}},"alternative-id":["10.1902\/jop.2001.72.7.932"],"URL":"https:\/\/doi.org\/10.1902\/jop.2001.72.7.932","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"value":"0022-3492","type":"print"},{"value":"1943-3670","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001,7]]}}}
