Enamel Matrix Derivative and Coronal Flaps to Cover Marginal Tissue Recessions

Background: Correcting recession defects is one of the goals of periodontal therapy, and the efficacy and predictability of the various techniques are important considerations for both patients and clinicians. Several reports have examined the outcome of gingival recession treatment by means of coronally positioned flaps (CPF) and enamel matrix derivative (EMD). The purpose of this study was to clinically evaluate the use of EMD in association with CPF to cover localized gingival recessions compared to CPF alone.Methods: Twenty-two patients with Miller Class I or II gingival recessions >2 mm were included. One recession from each patient was treated in the study. Two treatments were randomly assigned: coronally positioned flap with EMD (test) and coronally positioned flap alone (control). Clinical parameters measured at baseline and 1, 6, and 12 months included gingival index, plaque index, probing depth, clinical attachment level, vertical and horizontal recession, and width of keratinized gingiva.Result...
