Oklahoma Pit and Fissure Sealants State Practice Exam

Base and catalyst are also known as what?

1. Initiator and inhibitor

2. Binder and filler

3. Initiator and accelerator

4. Hardener and emulsifier

The correct answer is: Initiator and accelerator

Base and catalyst are commonly referred to as initiator and accelerator in the context of chemical reactions, particularly in materials such as dental sealants. The base typically serves as the primary substance that undergoes a chemical change, while the catalyst, often termed as the accelerator, facilitates this reaction without being consumed in the process. This terminology is crucial for understanding how various components work together in the setting and hardening of materials used in clinical practices, including dentistry. In the context of pit and fissure sealants, the acceleration of the polymerization process is vital for achieving the desired hardening effect quickly and effectively, ensuring longevity and protection for the tooth surface. Understanding these roles helps dental professionals appropriately select and use sealant materials in practice.
