The primary efficacy endpoint was percentage of root coverage (RC). Secondary efficacy parameters included width of keratinized tissue (KTw), probing depth (PD), clinical attachment level (CAL), clinician rating of color and texture compared with surrounding tissues, and patient esthetic satisfaction.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Seventeen patients were available for the 5\u2010year recall. Mean RC between 6 months and 5 years changed from 89.5% to 77.6% for CMX + CAF test sites and 97.5% to 95.5% for CTG + CAF control sites. KTw averaged &gt;3 mm for both test and control sites at 5 years. PD was equivalent at all time points. The 6\u2010month to 5\u2010year changes for RC, KTw, and PD were not significantly different between therapies. CAL change from 6 months to 5 years was greater for CTG + CAF (0.26 mm) than CMX + CAF (\u22120.21 mm). Tissue color match to surrounding tissues remained similar for both therapies throughout the study. There was a difference in tissue texture at both 6 months and 5 years, with CMX + CAF sites tending to be \u201cequally firm\u201d and CTG + CAF sites \u201cmore firm.\u201d Patient satisfaction was high, with no statistical difference in satisfaction between therapies at any time point.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    When balanced with patient\u2010reported satisfaction, clinical rankings of esthetics, and control and historical RC results reported by other investigators, CMX + CAF appears to present a viable and long\u2010term alternative to traditional CTG + CAF therapy.\n                  <\/jats:p>","DOI":"10.1902\/jop.2015.150386","type":"journal-article","created":{"date-parts":[[2015,10,15]],"date-time":"2015-10-15T12:21:33Z","timestamp":1444911693000},"page":"221-227","source":"Crossref","is-referenced-by-count":49,"title":["Long\u2010Term Results Comparing Xenogeneic Collagen Matrix and Autogenous Connective Tissue Grafts With Coronally Advanced Flaps for Treatment of Dehiscence\u2010Type Recession Defects"],"prefix":"10.1002","volume":"87","author":[{"given":"Michael K.","family":"McGuire","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
