Regenerative endodontic procedures are intended to replace damaged tooth structures, including dentine and root structures, in addition to cells of the pulp-dentine complex. This treatment modality have been tested on immature necrotic teeth because they are anticipated to have a greater chance of pulp tissue regeneration.
However, it has been recently suggested for treating fully formed mature necrotic permanent teeth with closed apices since the conventional root canal treatment yielded many drawbacks.
A number of studies have evaluated the regeneration outcomes of using blood clot as a scaffold. However, there are limited studies in the literature on using other scaffolds such as platelet-rich fibrin (PRF).
This clinical study will evaluate clinically and radiographically the effectiveness of PRF versus induced bleeding in treating mature necrotic teeth. Fifty patients with necrotic mature teeth with periapical lesions will be invited to participate in this study. Teeth will be treated using calcium hydroxide as intracanal medicament then using PRF (n=25) and blood clot (n=25) as scaffold. All teeth will be sealed coronally using NeoMTA Plus™. Treated teeth will be assessed clinically and radiographically using 2D periapical radiographs. The reported clinical and radiographic outcomes will be compared using SPSS.
