BACKGROUND AND OBJECTIVE: The aim of this interventional, parallel-assignment, single-blinded, randomized, efficacy study was to investigate the efficacy of the treatment of gingival recessions by osteogenic cell transfer. This is the first randomized clinical trial of this nature.
MATERIAL AND METHODS: Treatment of Miller class I or II gingival recessions >4 mm was randomly defined by casual sorting and performed by newly forming bone graft (NFBG) and coronally advanced flap (CAF) or subepithelial connective tissue graft (SCTG) and CAF (control). Clinical examinations were performed by a single blinded examiner at baseline and at 3, 6, and 9 months after surgery. Parameters investigated were recession height (REC), probing depth (PD), clinical attachment level, gingival bleeding index (GBI), plaque index (PlI), and keratinized gingiva width (KGW).
RESULTS: Both techniques achieved similar percentage of root coverage, but NFBG was more effective in pocket depth reduction, attachment level gain, and reduction of plaque accumulation and of bleeding on probing.
CONCLUSIONS: These findings suggest that the transfer of osteogenic cells by NFBG is able to improve clinical attachment level and to cover denuded roots. NFBG can be used as an alternative treatment of deep recessions (≥4 mm), where the restoration of lost periodontal tissues is intended.
