A porcine collagen matrix (Mucograft®) vs connective tissue graft in the treatment of multiple gingival recessions: A comparative clinical study

Abstract

Aim: The aim of this study was to compare the use of porcine collagen matrix (PCM) (Mucograft®) with coronally advanced flap (CAF) and connective tissue graft (CTG) with CAF in the treatment of multiple gingival recessions (MGRs). Materials and methods: Ten patients with 48 multiple recessions were enrolled in this study and divided into test group (PCM + CAF) and control group (CTG + CAF). Clinical param-eters, such as gingival recession (GR), probing depth (PD), clinical attachment level (CAL), and width of keratinized tissue (WKT) were recorded at baseline and at 6 months follow-up. Root coverage (RC %) and complete root coverage (CRC) were evaluated at 6 months postsurgery. Results: The mean of GR at baseline was 3.23 ± 0.49 in the PCM + CAF group and 3.25 ± 0.53 in the CTG + CAF group. At 6 months, the mean of GR reduction was 0.17 and 0.08 mm for PCM + CAF and CTG + CAF respectively, and CRC was obtained in 83% in the test group and 71% in the control group. The mean WKT gain was 1.58 mm in the test group and 1.42 mm in the control group (p < 0.001). Conclusion: Within the limitations of this study, using PCM + CAF in the treatment of MGRs is a successful option and could serve as an alternative to CTGs. Clinical significance: The PCM with CAF represents a clinical and esthetic treatment of MGRs.
