Clinical Trial Summary

This study is meant to assess clinically the possible predictable clinical attachment gain regarding the use of vitamin C with platelet rich fibrin versus platelet rich fibrin alone in the treatment of periodontal intrabony defects

Description:

Treatment of intra-osseous defects through incorporation of vitamin C into platelet rich fibrin scaffold aims to enhance the biologic potential of the endogenous mesenchymal stem cells that exist within the periodontal ligaments and stimulate periodontal tissue regeneration(Yan et al., 2013). As the concept of periodontal tissue-engineering has emerged, many inductive biomolecules were investigated for periodontal regeneration(Bartold et al., 2000).

Vitamin C has shown promising results in periodontal regeneration, in a study vitamin C was suggested to enhance osteoblastic differentiation of periodontal ligament cells through modulating type I collagen-α1β2 integrin interaction leading to increased ALP activity in periodontal ligament cells(Ishikawa et al., 2004). Vitamin C treatment induces expression of cementogenic genes and considered to be a more feasible and safer treatment for clinical cell-based periodontal regeneration(Gauthier et al., 2017).

There is also a study concluding that vitamin C induces the osteogenic differentiation of PDL progenitor cells via PELP1-ERK axis; and this implies that vitamin C may have a potential in the periodontal regeneration(Yan et al., 2013).

Periodontal tissue regeneration aims to increase periodontal in intra-osseous defects thus improving clinical attachment level; reducing probing depth and upgrading the prognosis of teeth(Ramseier et al., 2012).

Resolution of intra-osseous defects through regeneration preserves and improves function and provides patient comfort(Wang et al., 2005). It also facilitates supportive periodontal therapy; performed regularly to maintain periodontal health(Ramseier et al., 2012).
