Which of the following is NOT a characteristic of compomers compared to hybrid composites?

Compomers, which are materials that combine features of resin composites and glass ionomer cements, do have some distinguishing characteristics when compared to hybrid composites. One important characteristic is their ability to absorb moisture, which can lead to acid-base reactions. This is due to their composition, allowing them to interact with the surrounding environment differently than hybrid composites.

Additionally, compomers are designed to release fluoride, a beneficial property that enhances caries resistance through bonding with saliva. This fluoride release is crucial in maintaining the health of surrounding dentin during restorative procedures.

The statement regarding the compressive strength is significant here. Although compomers can be quite strong, hybrid composites generally demonstrate higher compressive strength. This higher strength allows hybrid composites to perform better under the stress of occlusal forces, which is especially important for restorations in posterior teeth (Classes 1 and 2).

The final option emphasizes that hybrid composites are the materials specifically recommended for Class 1 and 2 restorations. While compomers may also be used in some cases, they are not the sole materials for these classifications, making the statement valid.

Therefore, the option stating that compomers have a higher compressive strength does not hold true when compared to hybrid composites, highlighting the importance of proper
