The objective of this split-mouth, double-blind, randomized controlled trial was to compare the clinical effect of treatment of 2- or 3-wall intrabony defects with open flap debridement (OFD) combined or not with enamel matrix proteins (EMP). Thirteen volunteers were selected with one pair of or more intrabony defects and probing pocket depth (PPD) > 5 mm. All individuals received instructions regarding oral hygiene and were submitted to scaling and root planing. Each participant received the two treatment modalities: test sites were treated with OFD and EMP, and control sites received only OFD. After 6 months, a significant reduction was observed in PPD for the EMP group (from 6.42 ± 1.08 mm to 2.67 ± 1.15 mm) and for the OFD group (from 6.08 ± 1.00 mm to 2.00 ± 0.95 mm) (p < 0.0001), but with no significant difference between groups (p = 0.13). A significant gain in relative attachment level (RAL) was observed in both groups (EMP: from 13.42 ± 1.88 mm to 10.75 ± 2.26 mm, p < 0.001; OFD: from 12.42 ± 1.98 mm to 10.58 ± 2.23 mm, p = 0.013), but with no significant difference between groups (p = 0.85). Gingival recession (GR) was higher in the EMP group (from 1.08 ± 1.50 mm to 2.33 ± 1.43 mm; p = 0.0009) than in the OFD group (from 0.66 ± 1.15 mm to 1.16 ± 1.33 mm; p = 0.16), but this difference was not significant (p = 0.06). In conclusion, the results showed that OFD combined with EMP was not able to improve treatment of intrabony defects compared to OFD alone.

We undertook a randomized controlled trial of subzone II fingertip amputations, comparing standard treatment with topical application of gelatin microspheres prepared with basic fibroblast growth factor (b-FGF) to provide a slow, sustained release of b-FGF with microsphere degradation. Forty-eight digits from 42 patients were randomized into the two study arms. The microspheres were applied as a paste on exposed tissue surfaces, whereas standard treatment was without any topical treatment. Patients were treated either with microsurgical revascularization or by simple composite graft, based on the surgeon’s clinical decision. Tissue survival of the replanted fingertips was measured by a blinded evaluator 3 weeks postoperatively. A modest improvement in survival was seen with b-FGF-microsphere application for both revascularized and composite grafted fingertips, though this did not achieve statistical significance. Whether the slow release of b-FGF through a bioresorbable carrier gives any improvement in outcome in patients with subzone II fingertip amputations is unproven.
