AIM: To systematically review the literature and to determine the clinical performance of @entity1104 ( @entity1104 ) for the treatment of @entity154 ( @entity154 ). METHODS: RCTs on @entity154 treatment with 12 months of follow-up were identified through electronic databases and hand-searched journals. Primary outcomes were tooth survival, clinical attachment (CAL) gain, @entity92 ( @entity92 ) reduction and @entity1464 increase (REC). Weighted means and forest plots were calculated for each outcome variable 12 months after surgery. Long-term stability was explored with RCTs of at least 24 months of follow-up. Subgroup analysis was performed according to the type of flap. RESULTS: Twenty-seven trials reporting 647 subjects and 734 defects were identified. Twelve months after @entity1104 , tooth survival was 98% (IQ: 96.77-100), CAL gain 1.65 mm (95% CI: 1.37-1.94; p < 0.0001), @entity92 reduction 2.80 mm (CI: 2.43-3.18; p < 0.0001) and REC increase 1.26 mm (CI: 0.94-1.49; p < 0.0001). Longer follow-up showed similar findings. CI of CAL gain were 1.44-3.52 for recently introduced papilla preservation flaps and 1.25-1.89 mm for access flaps. CONCLUSIONS: The treatment of @entity154 with @entity1104 is associated with high tooth retention and improvement of periodontal clinical parameters. Clinical performance may vary according to the type of surgical flap used.
