Utilization of a Bovine Xenograft to Achieve Dental Root Coverage: A Pilot Study

Eight patients with 38 Miller Class I, II, and III gingival recession defects were treated using an acellular bovine dermal matrix graft (Primatrix, Integra) under a coronal positioned flap. There was a significant 2.43-mm reduction in defect depth, 85.96% mean root coverage, and 65.79% complete root coverage at the 6-month follow-up. Patients reported a significant improvement in perceived esthetics as well as trends for reduced dentinal hypersensitivity, minimal postoperative pain, and overall satisfaction with the procedure. The favorable clinical outcomes and oral biocompatibility would benefit from comparative trials to evaluate the material against contemporary grafting techniques.
