Abstract: Objective To observe the longterm clinical outcome of the resin restoration plus multiple coronally advanced flap technique (MCAF) for the treatment of gingival recession associated with noncarious cervical lesion (NCCL). Methods Three patients with multiple gingiva recession with NCCL were selected, and the resin restoration + MCAF combined with subepithelial connective tissue graft (SCTG) was performed to repair the soft and hard tissue defects. Pocket depth (PD), bleeding index (BI), plaque index (PLI), recession height (RD), keratinized tissue width (KTW) and gingiva thickness (GT) were measured at baseline and followup 3year after treatment and the root coverage esthetic score (RES) was calculated. Results Totally 3 patients and 10 sites were treated. The mean PD at baseline and followup were (1.10±0.32) mm and (1.65±0.34) mm, P=0.001. The mean BI at baseline and followup were (0.10±0.32) and (0.50±0.53) mm, P=0.037. The mean PLI at baseline and followup were (0.30±0.48) mm and (0.40±0.52) mm, P=0.660. All sites achieved 100% root coverage and significant augmentation of KTW and GT, and the P value was ＜0.000, 0.003 and ＜0.000. The mean RES at 3year followup was 9.40±0.95. Conclusion The resin restoration plus MCAF could efficiently repair the soft and hard tissue defects caused by NCCLs, and present a great esthetic outcome.
