The aim of this study was to compare the outcomes in the early wound healing after harvesting a subepithelial connective tissue graft (SCTG) using the single incision technique and collagen haemostatic sponge (CHS) placement, with and without suturing the palate. 36 subjects were randomized to receive (n=18, Suture group-SG) or not a suture (n=18, no Suture group-nSG). Outcomes variables were: Early healing index (EHI) at 7, 14 and 30 days, self-reported pain using a visual analogue scale (VAS) at 7 and 14 days, immediate (iB) and delayed bleeding (dB). Data obtained were compared by Fisher's exact test, T test for independent sample, Mann-Whitney test (U test) and Wilcoxon sign test as appropriate. The level of significance was set at p < 0.05. Statistical analysis was performed with Infostat version 2015.
This study evaluated the outcomes in the early healing of palatal wounds after harvesting a subepithelial connective tissue graft (SCTG) using the single incision technique with placement of a collagen haemostatic sponge (CHS) without suturing the palate. The primary outcome of this study was to evaluate the early wound healing index (EHI).
