The Use of Platelet Rich Fibrin in Pulpal and Periodontal Regeneration in Mature Teeth

Completed · Not applicable

Conditions studied: Pulpal Necrosis

In brief

In cases of permanent tooth avulsion, it is widely accepted that some necrosis always occurs after avulsion injury. If the pulp tissue does not revascularize or if endodontic therapy is not performed, the pulp space can become infected. Platelet rich fibrin (PRF) is a second generation platelet concentrate that allows the clinician to obtain fibrin membranes enriched with platelets and growth factors from an anticoagulant-free blood harvest. Clinical relevance of PRF and revascularization has been demonstrated in several case studies of avulsion. To date no human clinical trials have been performed evaluating the effectiveness of PRF on pulpal revascularization after reimplantation and its benefits in limiting inflammation. The following study consists of two phases: Phase 1: An in vitro model evaluating the effects of PRF in limiting inflammatory response of pdl cell cultures in the presence of an inflammatory mediators. Phase 2: An in vivo model utilizing mature teeth previously treatment planned for extraction, treating with PRF, reimplanting teeth and following for three to four months before extracting and performing histological analysis. If PRF is capable of promoting revascularization in mature teeth the potential benefits extend to limiting the need for endodontic therapy following mature tooth avulsion, potential for mature tooth transplantation in situations of congenitally missing teeth, and utilization of PRF in endodontic revascularization therapy.
