## **Core Concept**
In dental restorations, particularly for Class V cavities, the material used must adhere well to tooth structure, withstand occlusal forces, and ideally provide some protection against caries. Class V cavities are typically found on the gingival third of the facial or lingual surfaces of teeth.

## **Why the Correct Answer is Right**
The correct answer, Glass Ionomer Cement (GIC), is often considered the material of choice for Class V cavities due to its adhesive properties to tooth enamel and dentin, fluoride release which provides protection against secondary caries, and biocompatibility. These characteristics make GIC particularly suitable for non-load bearing restorations like those often required in Class V lesions.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option does not specify a dental material commonly used for restorations, making it an unlikely choice for Class V cavities.
- **Option B:** While composite resins are widely used in dentistry for various restorations, they may not bond as well to dentin as GIC and do not release fluoride.
- **Option C:** This option seems to be missing or incomplete and does not directly correspond to a commonly recognized dental restorative material.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that Glass Ionomer Cement (GIC) is especially useful in cases where a high fluoride release is beneficial, such as in patients at high risk of caries or in non-load bearing restorations like Class V cavities.

## **Correct Answer:** D. Glass Ionomer Cement.
