Abstract

Objective To compare dogûs dental pulp response to partial pulpotomy sealed with improved white Portland cements and ProRoot MTA®. Materials and methods Partial pulpotomy was done in four dogs thirty-five premolars teeth and divided into three groups. Group 1 was capped with ProRoot® MTA mixed with sterile water (n = 10). Group 2 was capped with Portland cement with bismuth oxide mixed with 5% calcium chloride and 1% methyl cellulose (n = 20). After pulp capping, teeth were based with glass ionomer cement and restored with resin composite. Both groups were done in seven and seventy days. Group 3 was positive control group, pulp exposure was open for seven days (n = 5). Teeth were extracted under anesthesia and processed for histopathologic examination to evaluate inflammation and hard tissue formation of the pulp. Results were analyzed by Kruskal-wallis and Chi-square at 0.05 level of confidence. Results There is no statistically different between ProRoot MTA and Portland cement to pulp inflammation and healing in seven and seventy days. No inflammation was observed in both experimental groups. In addition, completed hard tissue formation were detected. The hard tissue morphology and thickness were also not different between both groups. However, significant difference was found between the experimental groups and positive control group which showed moderate to severe inflammations. Conclusion Thai Portland cement with bismuth oxide mixed with calcium chloride and methyl cellulose, when used as pulp capping material, could retain pulp vitality without inflammation and also promote pulp healing and repaired process. Furthermore, it could induce hard tissue formation similar to ProRoot® MTA.
