Platelet-rich fibrin as a tissue engineering material in accelerate bone healing in rat bone defects: A systematic review and meta-analysis.

Introduction: Various techniques for tissue engineering have been introduced to help regenerate damaged or lost bone tissue. This study aimed to see the potential implication of platelet-rich fibrin (PRF) to accelerate the bone healing process in rat bone defects.

Methods: A systematic literature search was conducted from several electronic databases on subjects looking at the use of PRF in rat bone defects and their results in bone regeneration. Specific results compared PRF vs. other methods, PRF vs. control, and PRV vs. combination PRF and other methods. Science Direct, PubMed, and Cochrane Library were the main information sources. The Cochrane Collaboration method is employed to assess the risk of bias.

Results: A total of 483 rats were used in the twelve studies, and this meta-analysis showed that the PRF vs. other methods pooled odds ratio (OR) obtained was 0.92 (95% CI 0.42-2.04; p = 0.29; I = 18%), PRF versus control OR obtained 9.45 (95% CI 4.68-19.08; P = 0.01; I = 0%), the combination of PRF compared to PRF alone OR obtained 0.12 (95% CI 0.03-0.41; p = 0.01; I = 0%).

Discussion: Platelet-rich fibrin accelerates the bone healing process in rat bone defects compared to physiologically. Platelet-rich fibrin combined with other methods can stimulate rat bone defects than utilization of platelet-rich fibrin only. The small number of articles assessed may cause limitations in sensitivity tests. This study was registered in the research registry (reviewregistry1341).
