Abstract

Background: The importance of esthetics has escalated over the years. The purpose of any perioplastic surgery is to address gingival recession while ensuring predictable root coverage and a pleasing appearance. An array of surgical procedures have been recommended for the management of recession defects. The present study compares the clinical and patient related outcome measures of coronally advanced flap with chorion membrane and connective tissue graft in the management of multiple adjacent gingival recessions. Methods: The study was a prospective randomized controlled trial which included eight systemically healthy patients with an age range of 30-44 years with 36 labial/buccal, multiple adjacent, Cairo's RT1 gingival recession defects, bilaterally. CAF+CM was performed on one side whereas CAF+CTG was performed on the other side. The two groups were compared clinically at three and six months postoperatively. Results: There was statistically significant decrease in recession depth, recession width, probing depth and clinical attachment level in both the groups from baseline to three and six months. However, intergroup comparisons revealed no statistically significant difference. At six months, both groups showed statistically significant improvements in keratinized tissue width and gingival thickness. The gingival thickness of the CAF+CM group increased significantly at three and six months. In terms of root coverage aesthetic score (RES), there was no significant difference observed between the two groups. In terms of patient reported outcome measures (PROMS), patients preferred the CAF+CM technique. Conclusion: Within the limits of the current study, the use of chorion membrane resulted in considerable root coverage and increased gingival thickness. Periodontal regeneration can be facilitated by the distinctive features of the chorion membrane. Coronally advanced flap plus chorion membrane is a novel approach for root coverage procedures.
