Abstract

Objective: 

Resin-based composite (RBC) restoration are susceptible to degradation by acids. Recent advances in RBC have incorporated organically modified ceramics into their formulations. The objective of the study was to document the effect of combined solution of lactic and acetic acids on the microhardness values of two ceramic based nanohybrid composites (CBNC).

Materials & Methods:

This experimental laboratory-based study was conducted on 40 specimens, 20 in each of the two CBNCs (Tetric N-Ceram and Ceram-X). The test specimens were made in a standard split mold having dimensions of10 mm diameter and 2 mm thickness. The specimen was cured and the baseline Vickers hardness number (VHN) was measured and the remaining microhardness assessment was done after the various immersion periods of 0, 2, 7 and 21 days. The data was analyzed in statistical program (SPSS version 25.0). Descriptive statistics along with repeated measures ANOVA was used for the comparison of microhardness. The level of p-value to be significant was set as 0.05.

Results:

The change in microhardness of both Tetric N-Ceram and Ceram-X after immersion in test media was statistically insignificant. It can be concluded that there was no effect of combined solution of acids on surface microhardness of both test materials.

Conclusion:

Within the limitations of this study it was concluded that the microhardness of Ceram-X and Tetric NCeram did not change significantly after different immersion periods in test immersion media.
