Clinical evaluation of periosteal pedicle flap in the treatment of gingival recessions for esthetic root coverage: A randomized controlled clinical trial.

Abstract

Root coverage using subepithelial connective tissue graft (SCTG) is gold standard with few drawbacks such as requirement of second surgical site, reduced donor tissue availability, and increased surgical complications and pain. Periosteal pedicle graft (PPG) due to its rich source of pluripotent stem cells and nonrequirement of second surgical site could be a successful alternative for invasive SCTG. Therefore, current research aims to compare the amount of root coverage obtained with PPG to SCTG. Fifty-two single gingival recessions were included in the sample, with 26 patients allocated to the SCTG (control) and PPG (test) groups at random. At baseline, 3, and 6 months after surgery, clinical measurements of probing depth, clinical attachment level (CAL), recession depth (RD), recession width (RW), and width of keratinized tissue were taken. Both procedures, i.e., SCTG and PPG, resulted in root coverage to a variable extent and a significant decrease in RD (1.69, 1.38 mm in SCTG and PPG groups, respectively) and RW, CAL gain is found in both the groups without any intergroup statistical variance. Complete root coverage (CRC) was obtained in 14 out of 26, i.e., 53.8% defects in both SCTG and PPG groups. A better comfort level is found in the group treated with PPG. Gingival recessions can be successfully treated with PPG, which has predictability comparable to SCTG and does not require a second surgical site.
