Abstract

Introduction: The aim of the present study was to compare the survival, periapical healing and regaining
sensibility of necrotic mature second premolars with periapical lesion following treatment with two different
regenerative protocols, Platelet Rich Plasma(PRP) versus Platelet Rich Fibrin(PRF) pulp regeneration. Both
regenerative endodontic procedures were used for regeneration of pulp tissue in the root canal.
Methods: Twenty eight patients with mature, single canalled, necrotic, and asymptomatic second premolar
with radiographic evidence of periapical lesion were included. At the first visit, the tooth was anesthetized,
isolated and an access cavity was performed. Mechanical preparation of root canals was performed using the
standardized technique reaching apical canal preparation to K-file size #40-60. Antibiotic paste was injected
in canal, and the cavity was temporarily sealed. Two weeks later, regenerative procedures were performed
by applying PRP (group 1) and PRF (group 2) in root canal and pulp chamber space. Collagen plug was
placed directly over platelet concentrates followed by biodentin. Survival was defined as retention of the
tooth in the arch at 12 months recall. Cone beam computed tomography assessments were done through
recording of bone healing of periapical lesion and density of pulp chamber space at 12 months recall. The
electric pulp test was used to record at 3,6,9 and 12 months follow-up.
Results: There was no statistically significant difference in survival of teeth and healing of periapical
lesions between the two groups at 12 months recall. Readings of sensibility revealed statistically significant
difference (P < .0001) between baseline and the 12-months follow-up,with no statistically significant
difference between the two groups.
Conclusions: PRP and PRF combined with revascularization protocol were successful treatment modalities
for survival of mature necrotic teeth and healing of periapical lesion. Platelet concentrates protocol is
successful in regaining sensibility of necrotic teeth.
