Multiple gingival recession coverage using indigenously prepared amnion-chorion membrane: a clinical study

A prospective clinical study was conducted to evaluate the effectiveness of indigenously prepared amnion-chorion membrane for the management of multiple adjacent gingival recession. 15 healthy subjects, 8 female and 7 male ranging in age from 18 to 55 years, with maxillary anterior and premolar gingival recession defects were included and all the subjects were treated with the Zucchelli technique along with the placement of amnion-chorion membrane. Clinical examination post-surgery revealed healthy gingival tissues with color and texture blending with adjacent tissues. Complete root coverage was obtained in 44 out of a total of 52 sites with percentage mean root coverage accounting to 97.77%. Also, a statistically significant increase in the width and thickness of keratinized tissue was observed (p < 0.01). Long-term, multicentric, randomized controlled clinical trials with a larger sample size are needed in the future to confirm the findings of the present study and explore the potential of amnion-chorion membrane for its use in regenerative periodontics.
