An Evaluation of Mechanical Properties of a New Dual-cure, Universal, Bioactive Luting Cement.

AIM AND BACKGROUND

The aim of this study was to determine the properties of a new luting cement, BioCem®, by evaluating shear bond strength (SBS) and flexural strength (FS).

MATERIALS AND METHODS

A total of 60 extracted deciduous molars were included in this study. Samples were divided into two groups: Group I, Fuji I® ( = 30), and group II, BioCem® ( = 30). Each tooth was embedded in one acrylic block, such that the flattened enamel surface was exposed. Cylinders of 6 mm diameter and 8 mm height were prepared and evaluated for SBS using a universal testing machine. Ten rods of 25 × 2 × 2 mm of each material were prepared using a custom mold to evaluate the FS using a universal testing machine. Statistical Package for the Social Sciences (SPSS) version 20.0 was used for statistical analyses. Intergroup analysis was performed using an independent sample -test.

RESULTS

Upon comparing the SBS values of the luting agents and prepared enamel surfaces, glass ionomer cement (GIC) displayed the highest value, while BioCem® displayed the lowest. Upon comparing the FS values of the luting agents and prepared enamel surfaces, BioCem® performed better than GIC.

CONCLUSION

BioCem® may be used as a luting agent for the cementation of stainless steel crowns (SSCs) on primary teeth.

CLINICAL SIGNIFICANCE

BioCem®, a recently developed luting cement, may be used for cementing SSCs to the surfaces of prepared deciduous teeth; it exhibits significantly higher FS but lower SBS than that of GIC.
