title: A comparative evaluation of subepithelial connective tissue graft (SCTG) versus platelet concentrate graft (PCG) in the treatment of gingival recession using coronally advanced flap technique: A 12-month study.
abstract: OBJECTIVE
  The objective of this study was to clinically evaluate and compare the efficacy of platelet concentrate graft (PCG) with that of subepithelial connective tissue graft (SCTG) using a coronally advanced flap technique in the treatment of gingival recession.
  
  
  METHODS
  Twelve patients with a total of 24 gingival recession defects were selected and randomly assigned either to experimental site-A (SCTG) or experimental site-B (PCG). The clinical parameters were recorded at baseline up to 12 months post-operatively and compared.
  
  
  RESULTS
  The mean vertical recession depth (VRD) statistically significantly decreased from 2.50 ± 0.48 mm to 0.54 ± 0.50 mm with PCG and from 2.75 ± 0.58 mm to 0.54 ± 0.45 mm with SCTG at 12 months. No statistically significant differences between the treatments were found for VRD and clinical attachment level (CAL), while keratinized tissue width (KTW) gain was statistically significant.
  
  
  CONCLUSIONS
  Both the SCTG and the PCG group resulted in a significant amount of root coverage. The PCG technique was less invasive and required minimal time and clinical maneuver. It resulted in superior aesthetic outcome and lower post-surgical discomfort at the 12 months follow-up.
