A Randomized Split Mouth Clinical Trial Comparing Mineral Trioxide Aggregate with a New Fast-setting Calcium Silicate Cement in Direct Pulp Capping of Primary Molars: A Preliminary Report from a Long-term Follow-up

AIMS AND OBJECTIVES: This study was done to compare the success rate of a novel fast-setting calcium silicate cement (protooth) with mineral trioxide aggregate (MTA) in direct pulp capping (DPC) of primary molars. MATERIALS AND METHODS: Forty-five patients with an age range of 5–7 years with 90 bilaterally symmetrical primary molars that had deep carious lesions were incorporated into a randomized split mouth clinical trial. Initially, the caries was removed. Afterward, the teeth randomly underwent DPC with either MTA or protooth. Restoration of the teeth was done by amalgam fillings. Clinical and radiographic examinations were performed after 6 months. To analyze the data, Chi-square statistical test was used. Values < 0.05 were considered statistically significant. RESULTS: After 6 months of follow-up, 88 teeth on 44 patients were available for evaluation. The MTA-treated teeth showed a success rate of 95.5%, while the same outcome for the protooth-treated teeth was 93.2%. The difference did not yield a statistically significant difference (p value > 0.05). CONCLUSION: The findings of this study showed favorable results for the novel calcium silicate cement “protooth” when compared to the outcomes of MTA in the DPC of primary molars. CLINICAL SIGNIFICANCE: The constant need for the development of more effective materials in the modern pediatric dentistry makes this novel cement of particular interest for pedodontists. The new cement is biocompatible, hydrophilic, and has fast-setting time and adequate tensile strength with favorable clinical results in the DPC of primary molars which can benefit pedodontists in their clinical practice.
