Treatment of Gingival Recession With Tunnel Technique Using Connective Tissue Graft and Injectable Platelet Rich Fibrin

Condition(s) studied

Investigational drug(s) / intervention(s)

Tunnel with connective tissue graft and injectable platelet rich fibrin: Tunnel with connective tissue graft and injectable platelet rich fibrin

Tunnel with connective tissue graft only: Tunnel technique with connective tossue graft only without injectable platelet rich fibrin

Study summary

Gingival recession is a common periodontal problem. Consequences include teeth sensitivity, poor esthetics and impaired oral hygiene access. Mild cases are managed by optimizing oral hygiene measures, correction of any causative factor such as faulty tooth brushing, improper dental restoration or denture clasp. Prescription of desensitization products such as specific tooth gels or mouth washes can manage the sensitivity problem. Deeper recession defects need to be addressed by surgical procedures. Coronally advanced flap with connective tissue graft is the gold standard procedure. However, it has some drawbacks due to the need for papillary incisions and vertical incisions in some cases. Within the era of minimally invasive periodontology, tunnel technique with connective tissue graft showed results comparable to coronally advanced flap with connective tissue graft but with some limitations. Addition of another agent may enhance the results of tunnel technique. Injectable platelet rich fibrin is known for its content of growth factors and effects on soft tissue healing. Aim: The study aim is to compare the surgical management of gingival recession with tunnel technique using connective tissue graft and injectable platelet rich fibrin to tunnel with connective graft without injectable platelet rich fibrin.

Methodology: 30 patients with miller class I or II gingival recession will be enrolled. 15 in the test group (Tunnel+ CTG+ i-PRF) and 15 in control group (Tunnel+ CTG). Clinical evaluation at 6 months

Eligibility

Primary outcome measure(s)

• Recession depth — 6 months after the surgery
  it will be recorded as the distance between the CEJ and gingival margin-measurements were performed at the mid-buccal aspect of the teeth, by manual probe and were rounded up to the nearest millimeter.
• Keratinized tissue height — 6 months
  It will be measured from the mucogingival junction to the gingival margin-measurements were performed at the mid-buccal aspect of the teeth, by manual probe and were rounded up to the nearest millimeter.
• Gingival thickness — 6 months
  It will be measured at a mid-buccal location 1 mm apical to the probing depth level with an spreader. It will be pierced, perpendicularly to the mucosal surface, through the soft tissue with light pressure until a hard surface is felt. The silicone disk stop will then be placed in tight contact with the soft tissue surface. Penetration depth will be measured.
