Description

Introduction. The study investigated the tensile strength of temporary zinc oxide cement reinforced with 23% ethanolic extract of propolis in upper premolars. Hypothesis Formulation Propolis extract 23% binds to zinc oxide temporary cement without significantly altering the tensile strength properties. Results Group A showed a tensile strength of 12.3 ± 6.5 MPa and a maximum load of 118 ± 58N. Group B showed a resistance of 15.9 ± 3.2 MPa and a maximum load of 134 ± 47N. No statistically significant differences (P>0.05) were found between the groups according to the Wilcoxon test. Conclusions The addition of 23% ethanolic extract of propolis to zinc oxide temporary cement does not significantly modify the tensile properties.

Methods. Thirty human upper premolars mounted on acrylic blocks were used with temporary crowns fabricated from a siliconized guide with condensation silicone. The teeth were divided into two groups: group A (control) with eugenol-free provisional cement and group B (experimental) with the same cement plus propolis extract. The tensile test was performed with an Instrom 3369 universal machine.
