The Effect of Platelet-Rich Fibrin (PRF) in Accelerating Periodontal Regeneration: A Randomized Controlled Clinical Trial.

BACKGROUND

Regeneration of periodontal tissues is an essential component in treating periodontal disease, and there is an increasing focus on biological agents that might improve the healing process.

MATERIALS AND

METHODS

The randomized controlled clinical study included a cohort of 60 individuals diagnosed with chronic periodontitis. Each participant was randomly allocated to one of two groups: the experimental group (n = 30), which underwent PRF in combination with traditional open flap debridement (OFD), and the control group (n = 30), which received OFD alone. Clinical criteria such as probing pocket depth (PPD), clinical attachment level (CAL), and bone fill percentage were assessed at baseline and after 6 months. Furthermore, cone-beam computed tomography (CBCT) was used to evaluate bone regrowth radiographically.

RESULTS

Following a period of 6 months, the experimental group had a notable decrease in postpartum depression (mean decrease of 4.2 mm) and an increase in central artery ligation (mean increase of 3.5 mm) compared to the control group, which had a mean decrease in postpartum depression of 2.8 mm and a mean increase in central artery ligation of 2.1 mm. The test group had a notably greater proportion of bone fill (45%) in comparison to the control group (30%). Further radiographic study verified enhanced bone regeneration in the areas treated with PRF.

CONCLUSION

The use of Platelet-Rich Fibrin (PRF) in combination with traditional periodontal surgery greatly expedites the process of periodontal regeneration, as shown by notable enhancements in clinical indicators and bone regeneration.
