Effectiveness of Hyaluronic Acid on Multiple Adjacent Gingival Recessions Using a Coronally Advanced Flap

The potential benefit of adding hyaluronic acid (HA) to the coronally advanced flap (CAF) operative technique to cover multiple adjacent recessions has not been sufficiently investigated. Improving aesthetics is one of the primary goals of root recession coverage periodontal surgery, and little is known about the same in multiple adjacent gingival recession coverage therapy. In patients with a sufficient amount (≥2 mm) of keratinized tissue, the coronally advanced flap (CAF) has been shown to be very effective in the treatment of multiple recessions, especially in terms of aesthetic results. The researchers concluded from a database search (Epistemonikos, Cochrane, Medline) that there is no evidence to support the use of HA + CAF to achieve greater root coverage in the treatment of multiple gingival recessions.
