Background and objectives: Platelet-rich fibrin (PRF) is a new generation of biomaterial that proved to be an effective tool in numerous clinical uses. This study aims at expanding the range effectiveness of PRF in promoting bone healing by histological evaluation.
Materials and methods: We performed a pair of two calvaria defects on 35 Wistar rats. The left defect was left empty as a control and the right defect was augmented with PRF. After 45 days, the experiment was terminated and the calvaria were collected and underwent morphological and histological analysis.
Results: New bone formations have been shown to be prevalent in the PRF augmented defect.
Conclusions: PRF increases the body's natural ability to heal and regenerate bone.
