Abstract
Background: Pulp capping is a dental treatment to prolong pulp vitality by applying biocompatible materials to the dental pulp. The selection of a pulp capping material with high compressive strength properties is crucial because the oral environment is subjected to repeated functional and para-functional stresses. Objective: To determine the differences in compressive strength of 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--tricalcium phosphate-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 (UTM). Data from the compressive strength test were subjected to Shapiro-Wilk normality test, one way ANOVA, and Tukey post hoc test. Result: The compressive strengths of the three groups of nano α--tricalcium phosphate-based pulp cap prototype materials were different. The compressive strength decreased as the percentage content of nano α--tricalcium phosphate decreased, but the results (between treatment groups) were not significant. 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).
