Objectives: The primary objective of this study was to assess the clinical and radiographic survival of teeth treated with the NHFS (non-hemostasis ferric subsulfate) pulpotomy – a novel pulpotomy technique in which hemostasis of the radicular pulp is not attempted or confirmed. A secondary objective was to determine if preoperative radiographic caries depth was predictive of pulpotomy survival. Methods: A retrospective chart review for children that received one or more NHFS pulpotomies between January 1st 2017 and May 31st 2022 was conducted. Preoperative radiographic caries depth was assessed with a modified version of the ICDAS™ radiographic scoring system. Three clinical outcomes (pain, pathological mobility, and soft tissue pathology) and two radiographic outcomes (pathologic radiolucency and pathologic root resorption) were used to determine pulpotomy survival. Teeth were evaluated at intermittent recalls within the study period. Kaplan Meier curves were used to estimate clinical and radiographic survival over time. A semiparametric Cox Proportional Hazards model was used to investigate the association between preoperative radiographic caries depth and pulpotomy survival. Results: A total of 821 teeth from 377 children were evaluated over the study period. The mean follow up time was 24 months. Survival analysis found the aggregate probability of clinical and radiographic survival at 24 months to be 97.6% (95% CI [96.1,98.8]) and 80.3% (95% CI [75.5,85.9]) respectively . An association between preoperative radiographic caries depth and pulpotomy outcomes could not be determined. Conclusions: NHFS pulpotomies demonstrated similar clinical and radiographic survival rates to comparable conventional pulpotomies in the literature. Therefore, confirmation of hemostasis may not be a valid indicator of pulpal inflammatory status.
