279 - Comparing Pulpotomy Medicament and Outcomes, an Observational Effectiveness Study

Purpose:

The aim of this study is to determine if there are differences with overall clinical and radiographic success rates of pulpotomies using ferric sulfate or calcium silicate cements, including NeoMTA and Biodentine, completed at Hennepin Healthcare in the clinical and operating room setting.

Methods:

Pulpotomies identified using the dental code D3220 on primary teeth completed between January 2015 and December 2021. Five hundred and sixty-three subjects were identified for a total of 790 teeth treated with pulpotomies. Data was collected between June 2025 and October 2025 for the potential of four year follow up data. Clinical failure was defined by soft tissue pathology, pain, percussion or palpation sensitivity and pathologic mobility, and radiographic failure defined by pathologic radiolucency or pathologic root resorption. Data collected and recorded on RedCAP. Statistical analysis completed in SAS.

Results:

At 12 months, the success difference between FS and CS is not statistically significant but becomes significant (p < 0.005) beginning at 24 months and continuing through 48 months.

When comparing calcium silicate cements to ferric sulfate pulpotomies, the NNT at 48 months was 5.1, which is comparable to previous studies.

Conclusions:

We have shown, with real-world data, the effectiveness of calcium silicate-based cements for primary teeth. Our findings contribute to an expanding knowledge base that CS pulpotomies are more successful than FS pulpotomies, and CS should be used in clinical practice, especially if the tooth is expected to be present for more than 12 months.
