This study found that both autogenous free gingival grafts (FGG) and 2-stage coronally-positioned flaps (CPF) effectively covered denuded roots, with no significant difference in success for treating gingival recession.

Area of Science:

  • Periodontology
  • Restorative Dentistry
  • Oral Surgery

Background:

  • Gingival recession exposes root surfaces, leading to esthetic concerns and sensitivity.
  • Surgical interventions aim to restore soft tissue coverage and improve periodontal health.
  • Autogenous free gingival graft (FGG) and coronally-positioned flap (CPF) are common procedures for root coverage.

Purpose of the Study:

  • To compare the relative success of FGG and CPF in achieving soft tissue coverage of denuded roots.
  • To evaluate the reduction in exposed root surface area and the change in gingival margin position.

Main Methods:

  • Eight patients with bilateral Class I or II gingival recession defects were included.
  • Defects were randomly assigned to either FGG or CPF treatment.

  • Surgical procedures involved root planing, citric acid conditioning (FGG), and flap repositioning (CPF), with outcomes assessed via standardized photographs at multiple time points.

    • Main Results:

    • Both FGG and CPF demonstrated success in covering denuded roots, with no statistically significant difference observed at 3 months post-surgery.
    • Maximum reduction in exposed root surface occurred at 2 weeks, followed by some graft recession.
    • Mean exposed root surface distance decreased from baseline to 1.301 mm for FGG and 1.400 mm for CPF at 3 months.

    Conclusions:

    • Both FGG and CPF are viable surgical options for treating gingival recession.
    • The choice between FGG and CPF may not significantly impact short-term root coverage success.
    • Further long-term studies are warranted to assess the durability of both procedures.
