Evaluating the efficacy of human placental amnion membrane in combination with modified coronally advanced flap technique in the management of gingival recession: An interventional study

Abstract

A common problem experienced by adults is the recession of the gingiva resulting in unpleasant appearance of their teeth. There are various techniques to achieve the gingival recession coverage (GRC). But, only few techniques such as connective tissue grafts, coronally advanced flap technique (CAF) have been proved effective in achieving 100% recession coverage. The present study aims at evaluating the efficacy of amnion membrane along with CAF in the management of GRC. Materials and methods: A total number of 10 patients with class I or class II gingival recession were included in the study. The clinical parameters such as Probing depth (PD), clinical attachment level (CAL), thickness of attached gingiva (TAG), width of keratinized gingiva (WKG), height of gingival recession (HGR), percentage of recession coverage (PRC) and recession coverage esthetic score (RCES) were measured at baseline, 3 months and 6 months post-operatively. The patients were treated using amnion membrane in combination with modified coronally advanced flap technique (MCAF). Results: The patients showed statistically significant improvement in all the clinical parameters at the 3 months and 6 months follow-up visit. 97.8% CRC was observed by the end of 6 months. Moreover, the RCES showed remarkable esthetic outcome at the post-operative 6 months visit. Conclusion: Modified coronally advanced flap technique produces excellent clinical outcomes in terms of GRC. The use of amnion membrane aids in faster healing and improves the TAG which is an important aspect for the long term stability of the results obtained.
