Objective: The objective of this study was to evaluate the histological response of rat molars to four materials placed on the dental pulp.Methods: We used 24 female Wistar rats (6 per group). The pulp chamber roof of the first and second upper molars was perforated. After control of bleeding (<5 minutes), a pulp coating material (ProRoot®MTA, Ifabond™, Calcipast+I or Biodentine™) was placed. After 30 days of treatment, the molars were observed under an optical microscope.Results: ProRoot®MTA produced no inflammation of any pulp (p<0.0005). With Calcipast+I, inflammation was absent only in 18.7% of the pulps. All samples in all groups presented pulpal vitality. The ProRoot®MTA, Ifabond™ and Biodentine™ groups showed a dentin bridge and reparative den.. View More»
