A single and dual component dental composite restorative featuring anti-microbial and low Coefficient of Thermal Expansion (CTE) compounds is disclosed. The exemplary anti-microbial compound is zinc oxide. The CTE of the dental composite restorative is the same as, or substantially similar, to that of dentin. By maintaining a CTE substantially similar to that of dentin, the Margin Percolation phenomenon is minimized, which decreases the incidence of secondary caries.
