The poly-acid modified composite are known as
**Core Concept**
The question is testing knowledge of dental materials, specifically types of composite resins used in restorative dentistry. **Poly-acid modified composite resins** are a class of dental restorative materials that combine the benefits of composite resins with those of glass-ionomer cements.
**Why the Correct Answer is Right**
Given the nature of the question, it seems to be pointing towards materials that incorporate poly-acid modifications, which are known for their ability to bond to tooth structure and release fluoride. These materials are designed to have improved mechanical properties compared to traditional glass-ionomer cements while maintaining some of their beneficial characteristics, such as fluoride release and adhesion to tooth structure.
**Why Each Wrong Option is Incorrect**
**Option A:** This choice is incorrect because it does not specify a known type of poly-acid modified composite.
**Option B:** Similarly, this option does not correspond to the known classification of poly-acid modified composites.
**Option D:** This choice is also incorrect as it does not match the description of poly-acid modified composites.
**Clinical Pearl / High-Yield Fact**
It's crucial to remember that **poly-acid modified composite resins** are used for their unique properties, including their ability to adhere to tooth structure and potentially release fluoride, making them a valuable option in certain clinical scenarios.
**Correct Answer:** D. Compomers
