Modified minimally invasive surgical technique with clindamycin-augmented or non-augmented platelet-rich fibrin in periodontal regeneration: A randomized clinical trial

Injectable platelet-rich fibrin (I-PRF), a second-generation platelet concentrate, is widely used to enhance soft and hard tissue healing alone or in combination with biomaterials, relying on its harboring of various pivotal growth/differentiation factors.

Description
Summary:Injectable platelet-rich fibrin (I-PRF), a second-generation platelet concentrate, is widely used to enhance soft and hard tissue healing alone or in combination with biomaterials, relying on its harboring of various pivotal growth/differentiation factors. This randomized trial assessed the effect of clindamycin (CLN) augmented injectable platelet-rich fibrin (I-PRF) with modified minimally invasive surgical technique (M-MIST) versus I-PRF alone with M-MIST on the clinical and radiographic parameters in the management of periodontal intra-bony defects in patients with stage-III grade B periodontitis. This is a 9-month parallel-grouped, two arm, double-blinded, randomized controlled trial (RCT) that included 28 patients (n = 28) with stage-III grade B periodontitis, who were allocated randomly to test- (CLN/I-PRF + M-MIST, 50 μL of CLN per 1 mL of I-PRF; n = 14) or control-group (I-PRF + M-MIST; n = 14). Clinical attachment level (CAL; primary outcome), probing depth (PD), gingival margin level (GML), plaque index (PI), and gingival index (GI) were recorded at baseline, 3, 6, and 9 months, whereas radiographic parameters radiographic linear defect depth (RLDD), and radiographic defect area (RDA) were recorded at baseline, 6, and 9 months. The CLN release kinetics from the I-PRF were further characterized. Compared to baseline, both groups independently demonstrated significant improvements in CAL, PD, GML, GI, PI, RLDD and BDA at 3, 6 and 9 months (p
