Aim: The study aimed to compare calcium hydroxide, mineral trioxide
aggregate (MTA), biodentine and platelet rich fibrin (PRF) as direct pulp
capping agents in permanent mandibular molars.
Materials and methods: 60 permanent mandibular molars with symptoms of
reversible pulpitis were divided into 4 groups according to the agent used (n
= 15): calcium hydroxide, MTA, Biodentine, PRF according to the direct
pulp capping agent used. The patients were recalled after 1 week, 1,3 6 and 12
months for pain and periapical status assessment.
Results: After a follow - up of 12 months PRF showed maximum dentine
thickness formation.
Conclusion: PRF can be used as an alternative to MTA for direct pulp
capping in teeth with reversible pulpitis.
Keywords: Platelet rich fibrin, direct pulp capping, tertiary dentine,
Biodentine.
