Abstract Aim To compare dental pulp responses to capping with iR oot BP Plus and mineral trioxide aggregate ( MTA ) in dogs. Methodology Pulps in 36 incisors of three 8‐month‐old beagle dogs were mechanically exposed and assigned to two experimental groups ( iR oot BP Plus group and MTA group, n = 15 per group) and one control group ( n = 6). Direct pulp capping was performed using either iR oot BP Plus or MTA . The animals were sacrificed 3 months later. Histological sections were stained with haematoxylin and eosin and categorized using a histologic scoring system. Statistical analysis was performed using the Mann–Whitney U ‐test, with the significance set at 0.05. Results The majority of specimens in both experimental groups were associated with complete calcified bridge formation and the absence of pulpal inflammation. There was no significant difference in pulp response to iR oot BP Plus or MTA after 3 months ( P > 0.05). Conclusion iR oot BP Plus and MTA had similar favourable results when used as pulp‐capping agents.
