Management of gingival recession by coronally advanced flap with and without amniotic membrane: A clinical study

Purpose: Recently, human amniotic membrane (AM) has been reported to have regenerative potential that facilitate repair in the field of oral and periodontal surgeries. Methods: Eighteen subjects with bilateral Miller's class I gingival recession defects were selected. Subjects were allocated randomly to treatment with coronally positioned flap + amnion allograft (test group) and coronally positioned flap alone (control group). The clinical parameters used in this study were width of attached gingiva (AG), clinical attachment level (CAL), pocket depth (PD), width of keratinized gingiva (WKG), length of gingival recession (RL), width of gingival recession (RW). Results: The mean width of attached gingiva at the control sites (A) was found to be 1.33 ± 0.50 mm (range 1.00-2.00), 2.00 ± 0.71 mm (range 2.00-3.00) and 2.22 ± 0.67 mm (range 2.00-3.00) on day 0, 90 and 180, respectively. Thus, it was increased by 0.67 mm and 0.89 mm on day 90 and 180 compared to that of the baseline, which are 50% and 67%, respectively. Conclusions: It can be concluded that combined coronally advanced flap and amniotic membrane have additional advantage in the outcome of periodontal therapy in the management of gingival recession.
