Clinical Evaluation Comparing Tunneled Coronally Advanced Flap and Modified Coronally Advanced Tunnel With Connective Tissue Graft for Managing Single Gum Recession

Clinical Evaluation of Tunneled Coronally Advance Flap (TCAF) Versus Modified Coronally Advanced Tunnel With Connective Tissue Graft in Management of Single Recession Defects (RT2): A Randomized Clinical Trial

The technique under investigation aims to provide effective root coverage while offering the advantage of being less invasive.

Limited RCTs have been found in the literature comparing the root coverage capacity of the tunneled coronally advanced flap versus modified coronally advanced tunnel combined with connective tissue graft in single RT2 defects. So, this trial aims to fill this gap of knowledge.

Inclusion Criteria:

• Patients with single RT2 gingival recession defect ≥ 2 mm
• Age >18 years old.
• Systemically healthy patients with no contraindications for periodontal surgeries.
• Gingival and plaque index less than 20%.
• No previous surgeries at the defect site.
• Accepts 6 months follow-up period (compliant patients).

Exclusion Criteria:

• RT1 gingival recession.
• Smokers >10 cigarettes a day a contraindicating for any plastic periodontal surgery.
• Poor oral hygiene.
• Active periodontitis patients.
• Patients on medications causing gingival enlargement.
• Pregnancy.
• Teeth mobility ≥ 1 mm.
• Patients using fixed or removable orthodontic appliances.
• Restoration and/or periapical radiolucency at the defect site.
