The objective of this study is to determine the effect of simulated body fluid (SBF) exposure on two types of opaque dental porcelain, i.e., local opaque dental porcelain and commercial opaque dental porcelain before it can be applied for the dental applications. The first type has been produced at the School of Materials and Mineral Resources Engineering. Two tests were applied to determine the environmental properties. These tests include; compression test and absorption of SBF. For compression test performed after immersed in simulated body fluid, very little changes in strength can be observed for both porcelains. The absorption of simulated body fluid test shows that no change in the weight and no obvious changes when observed under SEM after immersed in SBF at 37°C for certain time. The two types of opaque dental porcelain are nearly at the same range.
