ABSTRACT
BACKGROUND The chorion membrane has been used for several decades as an allograft in tissue repair and various periodontal regenerative procedures. The present study, conducted at a single center in India, aimed to evaluate and compare the clinical outcomes of 26 gingival recession sites in chronic smokers treated using a pouch and tunnel technique with connective tissue graft (CTG) and lyophilized chorion membrane (LCM). MATERIAL AND METHODS The study included 22 smokers with 26 sites of recession defect, with Miller's class I and class II gingival recession, which were allotted into control and test groups. The control group (13 sites) was treated with CTG, and the test group (13 sites) was treated with LCM. Clinical parameters like recession depth, recession width, relative clinical attachment level (RCAL), relative gingival position, width of attached gingiva, and width of keratinized gingiva were recorded at baseline and 6 months postoperatively. Visual analogue scores for pain and wound-healing index scores were assessed in the first week after surgery. RESULTS All clinical parameters showed significant improvements from baseline to 6 months postoperatively in the control and test groups. Recession width, RCAL, width of attached gingiva, and width of keratinized gingiva demonstrated significant differences, whereas mean root coverage percentage and recession depth did not show any significant differences between the study groups at 6 months postoperatively. CONCLUSIONS This study supports the role of LCM allograft as a scaffold to promote soft tissue regeneration and has demonstrated a favorable role for its use in root coverage procedures in patients who smoke.
