Comparison of the effect of novel fast setting calcium silicate cement containing fluoride (Protooth) and MTA in direct pulp capping of primary molars; A split-mouth randomized controlled clinical trial

Abstract

Objective: The aim of the current study was to compare the success rate of MTA with a novel fast setting calcium silicate cement (protooth) in Direct pulp capping(DPC) of primary molars. Methods: A total of 90 bilaterally symmetrical primary molars with deep carious lesions on 45 patients aged 5-8 years old were incorporated into a randomized split mouth clinical trial. After caries removal, the teeth randomly underwent DPC with either MTA or protooth. The teeth were then restored with amalgam. Clinical and radiographic evaluations were performed at 6 and 12 month intervals. Chi square test under SPSS 18 was utilized to analyze the data and the significance level was set at 0.05. Results: At the end of the final follow up, 72 teeth on 36 patients were available for evaluation. The overall success rate in the MTA treated teeth (94.5%) did not show a significant difference with the protooth treated teeth (91.7%; P value>0.05). Conclusions: within limitations of the current study, the findings from this study, indicated that the novel calcium silicate cement “protooth” can be successfully used in the direct pulp capping of primary molars with similar outcomes compared to MTA.
