About

The clinical trial studies patients with gingival recession defects (receding gums).

The goal of the study is to test whether the additional use of enamel matrix derivatives (EMD), combined with the use of a coronally advance flap (CAF) and a CM (collagen matrix), shows a better outcome compared to a comparison group. The comparison group comprises patients receiving treatment with CAF and CM without the use of EMD.

Full description

The study aims to evaluate the influence of the additional use of EMD in treatment of gingival recession defects using a coronally advance flap (CAF) and a CM (collagen matrix) by means of digital and clinical assessment methods. The reference group comprises patients receiving treatment with CAF and CM without the application of EMD.

In this prospective, randomized, controlled study, recession height and area, width and thickness of keratinized gingiva, pocket probing depth, and the clinical attachment level were measured at baseline and followed-up for one year.

15 patients with 24 gingival recession defects (Recession Type 1 after Cairo/Miller Class I or II) were recruited and were randomly assigned into the two treatment groups.
