ABSTRACT
Background: Gingival recession type 2 (RT2) is characterized by the gingival recession associated with loss of interproximal attachment. The interproximal attachment loss is less than or equal to the buccal attachment loss. Various surgical strategies, such as connective tissue grafts (CTG) and coronally advanced flaps (CAF), were employed to deal with this situation. However, the best technique remains controversial. The present study aimed to evaluate and compare the efficacy of different surgical techniques for treating RT2 gingival recessions, focusing on root coverage, clinical attachment level (CAL) gain, keratinized tissue width (KTW) increase, and patient-reported outcomes. Methods: Thirty participants with RT2 gingival recession were randomly assigned to 3 groups: Group A (CTG alone), Group B (CAF alone), and Group C (CTG+CAF). The outcome was assessed at baseline and six months post-surgery. Results: The combined technique (Group C) obtained the superior effects with 82.5% root coverage, a CAL gain of 2.8 mm, and a KTW increase of 1.8 mm. Group A and Group B confirmed 75.3% and 68.7% root coverage, CAL gain of 2.4 mm and 2.1 mm, and KTW increases of 1.5 mm and 1.2 mm, respectively. Patient-reported aesthetic satisfaction turned into highest in Group C. Statistical analysis indicated significant differences in results between the groups (p < 0.05). Conclusions: The combination of CTG and CAF offers the best clinical outcomes and patient satisfaction in treating RT2 gingival recessions. These results support the approval of combined surgical strategies as the ideal technique for treating complex gingival recessions.
