A two\u2010level (patient and site) model was constructed, with the 6\u2010month changes in bREC and iREC as the dependent variables.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> 1) Significant 6\u2010month increases in bREC (\u22120.6 \u00b1 0.7 mm) and iREC (\u22120.9 \u00b1 1.1 mm) were observed. 2) bREC change was significantly predicted by presurgery interproximal probing depth (PD) and depth of osseous dehiscence at the buccal aspect. 3) iREC change was significantly predicted by presurgery interproximal PD and the treatment modality, with defects treated with SFA in combination with a graft material and a bioactive agent being less prone to iREC increase compared to defects treated with SFA alone.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> After buccal SFA, greater post\u2010surgery increase in bREC must be expected for deep intraosseous defects associated with a buccal dehiscence. The combination of a graft material and a bioactive agent in adjunct to the SFA may limit the postoperative increase in iREC.<\/jats:p>","DOI":"10.1902\/jop.2015.150040","type":"journal-article","created":{"date-parts":[[2015,4,30]],"date-time":"2015-04-30T12:36:49Z","timestamp":1430397409000},"page":"1038-1046","source":"Crossref","is-referenced-by-count":23,"title":["Change
