    An in-vitro comparison of the setting time, pH and radio-density of pre-mixed calcium silicate pulpotomy cements
    (University of the Western Cape, 2024) Bargo, Asmaa Yousif; Peck, Craig
    Background: A pulpotomy is a procedure in Paediatric Dentistry aimed at preserving pulp vitality and maintaining tooth integrity. The choice of pulp medicament is crucial for successful outcomes. While Mineral Trioxide Aggregate (MTA) is considered to be the gold standard in a pulpotomy procedure, it has drawbacks such as high cost, variability in mixing, poor handling and long setting time. Several new calcium silicate-based materials have been developed over time, with updated formulations of MTA aimed at addressing these disadvantages. Biodentine, as the first calcium silicate cement indicated for pulpotomy, has been shown to have comparable properties and outcomes to MTA. Biodentine offers a more consistent mix and easier application, making it more comparable to the updated premixed MTA formulations. Aim: The aim of this study was to compare two relatively new pre-mixed calcium silicate medicaments (NeoPUTTY and TheraCal PT) to Biodentine (control) with regards to their setting time, pH and radio-density. The rationale for this study is focused on evaluating whether these newer products meet the criteria for an ideal pulp medicament, particularly in Paediatric Dentistry where efficiency and efficacy are paramount. Existing literature lacks research comparing these properties among newer pre-mixed medicaments. Methods: The study employed a comparative laboratory experimental design, following the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM) standards.
