Coronally advanced flap alone or with connective tissue graft in the treatment of single gingival recession defects: a long-term randomized clinical trial.

Background: Numerous surgical approaches for the treatment of single gingival recession (GR) defects are documented in the literature. The aim of this 5-year, split mouth-design, randomized clinical trial was to evaluate the effectiveness of coronally advanced flap (CAF) alone versus CAF with connective tissue graft (CAF+CTG) in the treatment of single Miller Class I and II GR defects.

Methods: Thirty-seven patients with 114 bilateral, single Miller Class I and II GR defects were treated with CAF on one side of the mouth and CAF+CTG on the other side.
