Clinical Evaluation of Injectable Platelet Rich Fibrin With Connective Tissue Graft for the Treatment of Deep Gingival Recession Defects.

Clinical Evaluation of Injectable Platelet Rich Fibrin With Connective Tissue Graft for the Treatment of Deep Gingival Recession Defects. A Controlled Randomized Clinical Trial.

Aim: The aim of this study was to determine whether the combined connective tissue graft (CTG) with injectable platelet rich fibrin (i-prf) with coronally advanced flap (CAF) improved root coverage of deep Miller Class I or II gingival recessions compared to CTG alone with CAF.

Methods: Seventy-two patients with Miller class I and II gingival recessions were enrolled. Thirty-six patients were randomly assigned to the test group (CAF+CTG+i-prf) or control group (CAF+CTG). Clinical evaluations were made at 6 months

Inclusion Criteria:

• ≥19 years of age,
• Periodontally and systemically healthy,
• FMPS and FMBS <15%,
• Presence of deep Miller class I and II gingival recession defect (≥3 mm in depth) at the buccal aspect of incisors,

Exclusion Criteria:

Smoking,

• Contraindications for surgery,
• Presence of recession defects associated with caries, deep abrasion, restoration or pulpal pathology.
