This study assesses the clinical and radiological success of pulpotomy of the second primary molars with irreversible pulpitis using
Formocresol, MTA and Platelet Rich Fibrin (PRF) and monitors the teeth to see the success of the treatments during (6 months-12
months). The research consisted of 36 upper and lower second primary molars for children between the ages of 5 and 9 years. Each
of them had one or more second primary molar with irreversible pulpitis requiring pulpotomy, and the molars of the research
sample were divided into three groups equally according to the treatment method followed (treatment with Formocresol, treatment
using MTA, and treatment using PRF). Treatments were evaluated through periodic child reviews and clinical and radiological
examinations of the treated tooth by three specialists from the Department of Pediatric Dentistry to assess the success of the
treatment. Where, we reviewed the patient to evaluate treatment after 6 months - 12 months. The treatment success rates of MTA in
pulpotomy of primary molars with irreversible pulpitis were slightly higher than PRF, while formocresol had the worst prognosis
among the materials used in pulpotomy. MTA is superior to PRF and formocresol in pulpotomy of primary teeth with irreversible
pulpitis, and PRF was a successful and effective material in pulpotomy ofprimary molars and it can be an alternative to formocresol
and MTA.
