Abstract
Sixty patients with irreversibly inflamed permanent molars from those attending the
diagnosis clinic at the Conservative Dentistry Department, Faculty of Dentistry, Alexandria
University, Egypt, were selected for this study. For each patient, pulpotomy procedure was
done. Hemostasis was achieved using a cotton pellet soaked with 2.5% NaOCl and applied
for 2-3 min, then radicular pulps were capped using different materials according to the
grouping. group I (n=15) was capped with Biodentine, group II (n=15) was capped with
MTA. group III (n=15) was capped with PRF+Biodentine, while group IV (n=15) was
capped with PRF+MTA. The cavities in all groups were restored using RMGIC then covered
with resin composite restorations. Patients in all groups returned to the clinic for clinical and
radiographic evaluation at the following one, three, six and 12 months.
CBCT imaging was used to assess the outcome of the treatments at the end of the
study period to detect any pathological changes that might develop and to evaluate the newly
formed dentin bridges under the pulpotomy materials. Pulse oximeter device was used to
evaluate pulp vitality throughout the study period for all groups by measuring the oxygen
saturation levels of the blood vessels.
During the follow-up period, 10 patients were lost during the follow up period and
did not attend for evaluation. Results showed that no statistically significant differences were
found in the clinical and radiographic success rates between all groups. CBCT evaluation
showed no statistically significant difference in the treatment outcomes for all groups.
However, Biodentine stimulated significantly thicker dentin bridges than MTA. Pulse
oximetry evaluation showed that the Regenerative pulpotomy procedure using PRF was able
to regain the vitality of pulpotomized teeth.
