RESUMEN
OBJECTIVES: To systematically review the performance of access flap (OFD) in the treatment of class II furcation defects (FD). METHODS: RCTs evaluating surgical treatment of class II FD with OFD, minimum 6 months follow-up were identified. Screening, data extraction, and quality assessment were conducted independently by three reviewers. The primary outcomes were tooth survival and change in the horizontal clinical attachment level (HCAL). Changes in vertical clinical attachment level (VCAL), reduction of pocket probing depth (PPD), recession increase (REC), horizontal (HBL), and vertical bone level (VBL) were also collected. RESULTS: The search identified 1571 studies out of which 11 articles met the inclusion criteria. Data analysis was performed on 199 patients and 251 FD. Tooth survival was seldom reported. Altogether with inflammatory amelioration, the weighted mean differences were for HCAL 0.96 mm [CI: (0.60, 1.32), p < 0.001], 0.55 mm [CI: (0.00, 1.10), p = 0.05] for VCAL gain. PPD reduction over 6 months was 1.38 mm [CI: (0.91, 1.85), p < 0.01]. Potential risk of bias was identified. CONCLUSIONS: Teeth with mandibular class II furcation involvement treated with OFD show significant clinical improvements 6 months after surgery. Nevertheless, in order to better understand the magnitude of these changes and their clinical relevance, prospective long-term trials are needed.

AIM: A moderate acute-phase response occurs 24-h following full-mouth non-surgical treatment (FM-SRP). The aim of this study was to compare acute-phase (24-h) and medium-term (3 months) inflammation after quadrant scaling (Q-SRP) versus FM-SRP. MATERIAL & METHODS: Thirty-eight periodontitis-affected subjects were randomly allocated to FM-SRP or Q-SRP after a baseline visit. Periodontal and anthropometric parameters were collected at baseline and 3 months. Serum samples were drawn at baseline, 1, 7, and 90 days after treatment. High-sensitivity assays of inflammation and endothelial assays were performed. RESULTS: FM-SRP produced a greater acute-phase response after 24 h [threefold increase in C-reactive protein (CRP), twofold increase in interleukin (IL-6), and a slight increase in tumour necrosis factor]. No differences in systemic biomarkers were noted between groups at any later follow-ups. Both periodontal treatments produced a comparable improvement in clinical periodontal parameters with no between-group differences. Treatment time was positively associated with the relative 24-h increase in CRP (R = 0.5, p < 0.001) and IL-6 (R = 0.5, p = 0.002), while the number of deeper (>6 mm) pockets predicted only the relative increase in IL-6 (R = 0.4, p < 0.05). CONCLUSIONS: FM-SRP triggers a moderate acute-phase response of 24 h duration compared to Q-SRP. Further research is needed to assess the eventual impact of such findings on the risk of vascular events is advocated. (ClinicalTrials.gov NCT01857804).
