Aim of the study was to evaluate the clinical efficacy of placental membrane with coronally advanced flap in covering single and multiple Miller's class I and II gingival recession defects.

STUDY DESIGN A total number of 60 teeth in 15 subjects were selected. Patients with bilateral Miller's class I and II gingival recession defects in the maxillary or mandibular anterior and premolar region were selected and divided into two groups using a split mouth design.

GroupI (Control) -30 recession defects treated with coronally advanced flap alone, using Zucchelli's technique.

Group II (Test) - 30 recession defects treated with coronally advanced flap, using Zucchelli's technique along with placental membrane.
