Aim: Various surgical procedures have been proposed as effective treatment methods for recession defects. The purpose of this study was to compare the clinical outcome of gingival recession therapy using coronally advanced flap (CAF) or semilunar coronally positioned flap (SCPF). Material and Method: Procedures were performed in 18 patients having bilateral miller class I or class II buccal recession defects. Randomly assigned sites received either CAF or SCPF treatment. Clinical parameters measured at baseline, 3 months and 6 months after the procedure included recession depth, clinical attachment level and pocket depth. Results: Recession depth decreases from 2.27 ± 0.80 to 0.33 ± 0.75 with coronally advanced flap (85.46% root coverage) and from 2.16 ± 0.68 to 0.57 ± 0.75 mm (73.61% root coverage with SCPF). The differences obtain after the treatment in recession depth (RD), clinical attachment level (CAL) and pocket depth (PD) between the two procedures were nonsignificant. Conclusion: The finding from this study indicates that coronally advanced flap and semilunar coronally positioned flap can be successfully used to treat class I and class II gingival recession. There was no statistically significant difference regarding the treatment outcome of two procedures. Clinical Significance: Both techniques can be used in clinical practice for treating gingival recession.
