Clinical outcomes of pulpotomy using a premixed injectable calcium silicate cement on mature permanent teeth: A two-center randomised controlled trial

Objectives: The aim of this study was to evaluate the outcomes of pulpotomies performed using a newly-developed, premixed, injectable calcium silicate cement with flowable consistency, compared to mineral trioxide aggregate (MTA) in mature permanent teeth with reversible pulpitis. Materials: and methods: Mature permanent teeth that met the inclusion criteria were randomly divided into two groups according to pulpotomy material (ProRoot MTA group, Endocem MTA Premixed group). After pulp exposure, the superficial pulp was either removed to a depth of 2 mm (partial pulpotomy) or completely amputated to the level of the root canal orifice (full pulpotomy). A 3-mm layer of either material was randomly placed over the pulp wound, followed by the application of a thin layer of a light-cured glass ionomer composite liner. The restoration procedure was then carried out during the same visit. Results: : Out of the total 87 teeth enrolled, 71 teeth (37 in the ProRoot MTA group and 34 in the Endocem MTA Premixed group) were clinically and radiographically evaluated at one year. The overall pulpotomy success rate was 94.4% (67/71); 93.9% in the ProRoot MTA and 97.1% in Endocem MTA Premixed with no significant difference between the groups. Calcific bridge formation occurred in 6 (24.0%) cases in the ProRoot MTA group and 10 (40.0%) cases in the Endocem MTA Premixed group. Conclusions: : Endocem MTA Premixed is a viable alternative to ProRoot MTA for single-visit pulpotomies of permanent molars. Clinical Relevance: Premixed injectable calcium silicate cement with flowable consistency can be considered as a potential alternative to MTA cement for single-visit pulpotomies.
