Abstract
Clinical data indicate that secondary caries and restoration fracture are the most common problems facing dental resin composites. The objective of this study was to combine whiskers with nano-sized MCPM (monocalcium phosphate monohydrate) particles in dental resins with the MCPM to release Ca and PO4 ions to combat secondary caries. The following mass ratios of MCPM:silicon carbide whiskers were tested: 1:0, 2:1, 1:1, 1:2, and 0:1. The composites were immersed for 1 d to 56 d to measure Ca and PO4 ion release. When the MCPM:whisker ratio was changed from 0:1 to 1:2 and to 1:0, the composite flexural strength (mean sd; n = 5) significantly decreased from (174 26) MPa to (138 9) MPa and to (38 11) MPa (pCitation
