Clinical Outcomes of Free Gingival Graft Following Recipient Bed Preparation with Er,Cr:YSGG Laser Versus Scalpel: A Split-Mouth Randomized Clinical Trial

Comparison of conventional and modified sling suture techniques in free gingival graft operations-a randomized controlled clinical trial

BACKGROUND

The aim of this study was to investigate the effects of conventional suture (CS) and modified sling suture (MSS) techniques, applied in free gingival graft (FGG) surgery using gingival unit graft (GUT) and conventional graft (CG) techniques, on clinical parameters and graft dimensions.

METHODS

52 individuals having Cairo Type 2 (RT2) and Type 3 (RT3) gingival recessions in mandibular anterior were divided into four groups as (a) GUT + MSS (n = 13), (b) GUT + CS (n = 13), (c) CG + MSS (n = 13) and (d) CG + CS (n = 13). Keratinized tissue width (KTW), relative gingival recession height (rGRH), and relative vestibule depth (rVD) measurements were recorded using a digital caliper and UNC 15 periodontal probe. Dimensional changes (Δ) of the graft surface area (GSA) was determined by ImageJ software. All measurements were done at baseline, 1st and 3rd months.

RESULTS

It was determined that the increase in KTW in the 1st and 3rd months in GUT + CS group was significantly higher than GUT + MSS group (p < 0.05). There was no statistically significant difference in Δ rVD and Δ rGRH values between the groups. When ΔGSA (mm2) values were compared between the groups, the decrease in the 1st and 3rd months in the CG + MSS group was found to be significantly higher than the GUT + MSS and GUT + CS groups (p < 0.05).

CONCLUSION

Within the limits of this study, it can be concluded that keratinized tissue can be obtained successfully with both GUT or CG techniques in FGG surgery, on the other hand, regardless of the suture technique, GUT showed less graft shrinkage than CG.

The Effects of Cyanoacrylate on Clinical Healing and Self-Reported Outcomes Following Free Gingival Graft Surgery: A Randomized Clinical Study

Objective: This study aims to reveal the effects of cyanoacrylate application at the recipient bed and the donor site in free gingival graft surgery on graft dimensions, clinical healing parameters and patient-based outcomes. Methods: Free gingival graft operations were conducted on individuals who were randomly assigned to control or test groups. In the test group, the graft was stabilized and the donor site was coated with cyanoacrylate. In the control group, 6/0 polyvinylidene fluoride sutures were used for stabilization, while the donor site was left untreated. Variables including re-epithelization, post-operative complications, pain, bleeding and quality of life at recipient site, and color match, graft dimensions at donor site were assessed for up to 6 months. Results: Twenty-three individuals completed the study. No differences were observed in any variable between groups except horizontal dimension loss of the graft, which was more abundant in the cyanoacrylate group at six months (p>0.05, p
