ABSTRACT
Objective: To evaluate differences in compressive strength among three prototype groups of pulp capping materials with different percentages of materials and one control positive group (TgCaviliner). Method: The object of the study was TgCaviliner and nano α-TCP based pulp cap prototype materials that were light cured in a cylindrical mold with a diameter of 4 mm and a thickness of 6 mm. The molded samples were removed and stored for 24 hours. After storage, the samples were tested for compressive strength using a Universal Testing Machine. Data were analyzed using the Shapiro-Wilk test, one way ANOVA, and Tukey post hoc test. Result: Compressive strengths varied among the prototype groups, with lower strength observed in formulations containing less nano α-tricalcium Conclusions: The results of the compressive strength test obtained an average value that exceeded the minimum limit required by the liner material of 5 MPa (ISO 3107 2011).
