The effectiveness of enamel matrix protein (Emdogain® ) in combination with coronally advanced flap in the treatment of multiple marginal tissue recession: A clinical study

Abstract

Background: Gingival recession resulting in root exposure is a common problem faced by clinicians. This clinical study compared the results obtained by treating gingival recession using enamel matrix derivative (Emdogain gel® ) along with coronally positioned flap and coronally positioned flap alone. Materials and Methods: Twenty patients with a total of 46 gingival recession defects, each patient with a minimum of two recession defects, were included in the study. The test group, which consisted of 10 patients with 22 recession defects, was treated by enamel matrix derivatives (Emdogain gel) in combination with a coronally positioned flap, while the control group, which consisted of 10 patients with 24 gingival recession defects, was treated with 24% ethylenediaminetetraacetic acid (EDTA; Prefgel® ) in combination with coronally positioned flap. Results: Student′s paired and unpaired t-test was used for statistical analysis. If the probability value (P) was less than 0.05, it was considered significant. Data from this study demonstrated that application of (EMD) Emdogain gel resulted in a statistically significant increase in root coverage, gain in the clinical attachment level (CAL), and probing pocket depth (PPD) reduction when compared with coronally advanced flap (CAF) alone, but there was no statistically significant difference in the width of keratinized gingiva (WKG) between the two groups.
