Treatment of gingival recession on permanent maxillary maxillary premolars by coronally advanced flap with a connective tissue graft

Abstract

Background: Gingival recession is a phenomenon in which the gingival tissue narrows in size towards the tooth root. The goal of gingival recession treatment is to achieve root coverage, increase gingival thickness, and stabilize the gingival margin over time. Objectives: To investigate clinical characteristics of gingival recession in permanent maxillary premolars and to evaluate the results of treatment of gingival recession in permanent maxillary premolars by means of flap surgery towards the tooth body combined with subepithelial connective tissue grafting. Subjects and methods: 30 maxillary permanent premolars were diagnosed with gingival recession according to Cairo type 1, cross-sectional descriptive research method, non-controlled clinical intervention. Results: Patients in the study had an average age of 28.67 ± 9.31 years. Regarding gender, our study had a relatively even distribution between men and women. The analysis results showed that there was no statistically significant difference between preoperative clinical indices at the first and second premolars in the study group. The rate of root re-coverage was 94.12% at 3 months after surgery, the rate of completely re-covered roots was 66.33% at 3 months after surgery. There were no cases of postoperative complications, clinical indicators all improved at 3 months after surgery. Conclusion: Treatment of maxillary permanent premolars by coronally advanced flap with connective tissue grafting is a highly effective and safe method in clinical practice.
