INTRODUCTION: The addition of some chemicals to mineral trioxide aggregate (MTA) may improve the physical properties of the biomaterial. The aim of this study was to compare a combination of MTA with/without CaCl(2) as pulp-capping agents in dogs' teeth. METHODS: The dental pulp of 32 teeth in four dogs were exposed and capped with either MTA or MTA/CaCl(2). After 2 months, the animals were sacrificed, and the teeth were prepared for histological evaluation. Pulpal response to the two capping materials was evaluated in terms of necrosis, inflammation, and formation of a calcified bridge. The chi-square test was used for data analysis. RESULTS: Histological results showed a higher percentage of inflammation and necrosis and a lower percentage of calcified bridge formation in MTA/CaCl(2) samples compared with MTA; however, the differences were not statistically significant (P > .05). CONCLUSIONS: The addition of CaCl(2) to MTA pulp-capping agent did not improve the properties of this biomaterial.
