What complex is added to prophylaxis paste to enhance enamel remineralization?

The use of MI paste and NuvaMin in prophylaxis paste is significant because these agents contain a bioavailable form of calcium and phosphate, which play crucial roles in enamel remineralization. The combination of these minerals is designed to mimic the natural mineralization process of teeth, thereby promoting the repair of early carious lesions and enhancing overall enamel strength.

MI paste contains a compound known as Recaldent, which delivers calcium and phosphate to the tooth surface. This helps in the remineralization process by replenishing minerals lost due to demineralization. NuvaMin is another product that provides similar benefits by delivering bioavailable calcium and phosphate, in addition to fluoride, which contributes to further strengthening of the enamel.

In contrast, other options such as quaternary ammonium compounds, triclosan, and hydrogen peroxide do not specifically focus on enhancing the remineralization of enamel. Quaternary ammonium compounds are more commonly used for antimicrobial purposes, triclosan also has an antibacterial function, and hydrogen peroxide is primarily known for its bleaching properties rather than promoting mineral restoration in teeth.
