Clinical evaluation of platelet-rich plasma and bioactive glass in the treatment of intra-bony defects

Abstract

Background: There are limited numbers of studies focused on the using of platelet-rich plasma (PRP) combined with different types of bone substitutes in intra-bony defects.

Aim: The purpose of this study was to evaluate the effect of bioactive glass graft material (BG) with and without PRP on the clinical healing of intra-bony defects.

Materials and methods: Twenty-nine intra-bony defects were randomly treated with either PRP/BG or BG alone. Clinical parameters were recorded at baseline and repeated 9 months after surgery and surgical reentries were also performed.

Results: The results showed that both treatment modalities were effective. Pocket depth reduction of 3.60 +/- 0.51 mm, clinical attachment gain of 3.3 +/- 1.77 mm and defect fill of 3.47 +/- 0.53 mm were noted in the PRP/BG group, with 3.29 +/- 1.68, 2.86 +/- 1.56 and 3.36 +/- 0.55 mm improvements, respectively, noted for the BG group. None of the differences between the two treatment modalities were statistically significant.

Conclusions: It is suggested that both PRP/BG combination and BG alone are effective in the treatment of intra-bony defects. The results also showed that using PRP with BG has no additional benefit in the reduction of pocket depth, clinical attachment gain and defect fill.
