What is incorrect regarding compomers?

Compomers, or polyacid modified resin composites, are a class of dental materials that combine features of both glass ionomer cements and resin composites. Understanding the characteristics of compomers helps clarify the nuances in their properties compared to other materials.

The correct assertion regarding compomers is that they have less fluoride release than resin modified glass ionomer cements (RMGIs). RMGIs are specifically formulated to release fluoride, which is beneficial for preventing caries and promoting remineralization. While compomers do release some fluoride, the quantity is generally lower when compared to RMGIs. This characteristic is important for clinicians to consider when selecting materials for restorative procedures, especially in situations where fluoride release is a priority for caries prevention.

The other statements about compomers accurately reflect their properties: they are polyacid-modified resin composites, they chemically bond to tooth structure through the polyacid component, and they do exhibit improved physical characteristics, such as aesthetics and wear resistance, compared to traditional glass ionomer cements. However, their fluoride release does not surpass that of RMGIs, marking the distinction that makes option B the incorrect statement.
