Aims: This parallel-group, multi-centre, double-blind, randomized-controlled clinical trial was undertaken to compare the clinical outcomes and patient morbidity of coronally advanced flap (CAF) alone or in combination with a connective tissue graft (CAF1CTG) in single Miller Class I and II gingival recessions. Material and Methods: Three centres enrolled 85 patients with one recession each. Surgery was performed elevating a pedicle flap; 42 sites randomly received a graft under the flap. Measurements were taken by blind and calibrated examiners. Outcome measures included recession reduction, complete root coverage (CRC), intra-operative and post-operative morbidity, dentine sensitivity, and side effects. Results: No differences were noted in the intra-operative and post-operative patientrelated variables between the two groups. Surgical time was significantly shorter in the CAF group. Recession reduction was not statistically different between the two groups, even though a model showed a tendency towards improved outcomes in sites treated with CAF1CTG (adjusted difference 0.33mm, 95% CI5 0.06 to 0.72, p50.1002). Significantly greater probability of CRC was observed after CAF1CTG (adjusted OR55.09, 95% CI51.69–17.57, p50.0033). Dentine hypersensitivity improved in both the groups. Conclusions: Both treatments were effective in providing a significant reduction of the baseline recession and dentine hypersensitivity, with only limited intra-operative and post-operative morbidity and side effects. Adjunctive application of a CTG under a CAF increased the probability of achieving CRC in maxillary Miller Class I and II defects

Measurements were taken by blind and calibrated examiners. Outcome measures included recession reduction, complete root coverage (CRC), intra-operative and post-operative morbidity, dentine sensitivity, and side effects. Results: No differences were noted in the intra-operative and post-operative patientrelated variables between the two groups. Surgical time was significantly shorter in the CAF group.
