HOSA Dental Terminology Practice

What does "self-cured" mean in dental terms?

1. Chemical polymerization of materials when mixed

2. Hardening under ultraviolet light

3. Application of heat to set materials

4. Instant hardening upon exposure to air

The correct answer is: Chemical polymerization of materials when mixed

In dental terminology, "self-cured" refers to the process of chemical polymerization of materials when mixed. This means that certain materials, such as dental resins or cements, undergo a chemical reaction triggered by the blending of two components, typically a base and a catalyst. As these components are mixed, they react to form a solid material without the need for external factors like light or heat. This process is particularly advantageous in various dental applications because it allows for the material to set at room temperature and in a reasonably quick timeframe after mixing. It is commonly used for applications such as filling cavities or bonding materials. While other curing methods such as those relying on ultraviolet light, heat, or exposure to air exist, they apply to different materials or scenarios and are not classified as self-curing. Understanding this distinction is crucial for selecting the appropriate dental materials and techniques for specific treatments.
