Objective: The objective of this study is to evaluate the diametral tensile strength and microhardness of an experimental cement and temporary restorative materials used in endodontics (Zinc Oxide and Eugenol, conventional glass ionomer, Clip F® and Coltosol® F). Material and methods: The sample of this in vitro study consisted in 11 samples were made from each provisional restorative materials, for each property to be evaluated. The samples were stored at room temperature for 24 h. The diametral tensile strength by compression was measured through the Instron® universal testing machine and the microhardness through the Vickers tip microdurometer. The results were analyzed using univariate descriptive statistics and the Kruskal Wallis test was performed for the bivariate analysis. Results: In this study, the experimental cement obtained higher values of diametral tensile strength (0.77 MPa + 0.34) in comparison of Coltosol® F (0.41 MPa + 0.13). In addition, it obtained higher microhardness results (9.45 HV + 0.66) in comparison of Coltosol ® F (6.50 HV + 0.61) and Zinc Oxide and Eugenol (5.62 HV + 0.61). However, lower diametral strength values were observed compared to glass ionomer (24.46 + 4.55) and Clip F® (23.06 + 2.91). Also, the microhardness values were lower compared to the conventional glass ionomer (38.62 + 0.67) and the Clip F® (26.03 + 1.07). In both properties, statistically significant differences were found (p <0.05). Conclusions: The experimental cement did not prove to be a good material compared to the conventional glass ionomer and the Clip F®. However, it obtained better results than Zinc Oxide and Eugenol, and Coltosol® F; which are commonly used in the dental field despite having poor properties.
