Compomer restorative materials are:
- A- Glass ionomer with polymer components.
- B- Resin systems with fluoride containing glasses.
- C- Composite resin for cervical restorations only.
The most accurate answer about compomer restorative materials is: A. Glass ionomer with polymer components.
Here's why the other options are incorrect:
B. Resin systems with fluoride containing glasses:
While some materials may use fluoride-containing glasses, this is not the defining characteristic of a compomer. Resin systems refer to composite resins, which are distinct from compomers.
C. Composite resin for cervical restorations only:
Composite resins are a different type of restorative material with distinct properties and are not limited to cervical restorations. Compomers are used for various situations besides cervical restorations.
Compomers:
Therefore, compomers are classified as a hybrid material combining the functionalities of both glass ionomer cement and composite resin. They contain:
- Glass ionomer components:
These provide fluoride release and adhesive properties to tooth structure.
- Polymer components:
These offer strength and aesthetic advantages compared to pure glass ionomer cements.
This combination offers specific advantages, such as fluoride release, ease of handling, and good wear resistance, making compomers suitable for various applications in dentistry.
