After tooth extraction, the sockets were randomly allocated to two groups applying a split\u2010mouth design: (1) ARP using deproteinized bovine bone mineral containing 10% collagen (DBBM\u2010C) covered by a collagen membrane and (2) spontaneous healing (control). CAL, probing pocket depth (PD), bleeding on probing (BOP), gingival recession (REC), and bone levels were evaluated at the adjacent teeth of the extraction sockets at baseline and after 6\u00a0months of follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 14 patients were available for reexamination.
