Background: This systematic review evaluated the most effective therapeutic approach to treat periodontal furcation defects with a minimum follow-up of 12 months. The primary outcome was clinical attachment level (CAL). Secondary outcomes were probing pocket depth, gingival margin level, gingival index and plaque index.
Methods: A comprehensive search of studies published up to December 2019 and listed in PubMed/MEDLINE, Scopus, and Cochrane Library databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) statement. Two reviewers independently searched eligible studies, made a final article selection, and extracted the data of the selected studies to evaluate qualitatively and quantitatively (meta-analysis).
Results: Overall, 19 studies were selected for the analysis. Six hundred and eighteen patients (mean age, 45.3) were treated. More commonly used treatment was polytetrafluoroethylene barrier (ePTFE), followed by enamel matrix derivative (EMD) and open-flap debridement (OFD). Only one study evaluated maxillary arch and remaining evaluated mandibular arch. All treatments provided CAL gain, but meta-analysis did not show significant difference among more commonly used treatments and controls (P=0.91; P=0.47; P=0.08, respectively).
Conclusion: There is no difference on effectiveness of main therapeutic approaches evaluated for treatment of Class II periodontal furcation defects.
