Abstract

Aim: The aim of this trial was to compare the semilunar coronally position flap (SCPF) and the conventional coronally advanced flap (CAF) regarding the applied modifications in treating gingival recession. Materials and methods: Sample consisted of 16 patients with bilateral class I gingival recessions, they were treated with SCPF or CAF. Two modifications were applied: a root surface biomodification with tetracycline (TTC) and suture anchors on the contact points of the tooth. Clinical parameters and a questionnaire were used as measures to evaluate the trial. Wilcoxon test was used for statistical analysis. Results: The mean percentage of root coverage (RC) and complete RC (CRC) was 82.3 ± 15.6% (31.3%, n = 5/16) and 79.8 ± 27.7% (43.8%, n = 7/16), respectively, using SCPF and CAF. Statistically significant differences were observed in the intergroup width of keratinized tissue (WKT), thickness of keratinized tissue (TKT), vestibular depth (VD), and position of the mucogingival junction (MGJ). A significant difference was observed in wound healing index (WHI) 1 week postoperative. Full root coverage esthetic score (RES) was achieved in four teeth using SCPF and in two teeth using CAF. No statistically significant differences were observed in the intergroup in the postoperative pain and root sensitivity during the follow-up. Conclusion: Both SCPF and CAF with the mentioned modifications were effective in managing shallow gingival recessions. However, SCPF’s results showed a significant gain in WKT, TKT, and VD. Clinical significance: Our findings confirm that both procedures with the mentioned modifications can be used to treat gingival recession with effectively and satisfied results for periodontist and patient. Our results suggest it is preferable to use the SCPF in case of a shallow oral vestibulum and high demanded for esthetic.
