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. |
