rhPDGF Mediated Root Coverage Procedure Using Coronally Advanced Flap in Treatment of Multiple Recession Defects: a Case Report

Gingival recession has been defined as the term used to characterize the apical shift of the marginal gingiva from its normal position on the crown of the tooth to levels on the ischolar_main surface beyond the cemento-enamel junction (CEJ). Numerous techniques have been developed for treatment of these defects including rotational and advanced gingival flaps, soft-tissue grafting procedures with autogenous and allograft materials. This paper illustrates a case report of 42-years-old male patient with a chief complaint of thermal ischolar_main sensitivity in relation with front teeth of lower jaw and describes a technique to coronally advance the flap in combination with recombinant human platelet-derived growth factor-BB (rhPDGF-BB) (GEM 21S) to treat multiple gingival recession defects. Patient was followed postoperatively, and healing was evaluated at 1, 3 and 6 months, with recession depth as the primary outcome measure. This case report revealed a favourable tissue response to GEM 21S from both clinical and aesthetic points of view showing excellent plastic surgery results for gingiva.
