A two-part sealant system is often referred to as what?

• A. Self-cured materials
• B. Light-cured sealants
• C. Filled sealants
• D. Unfilled sealants

Answer: (A)

Two-part sealant systems cure by a chemical reaction that starts when the base and initiator components are mixed. This internal, self-driven setting process is why they're described as self-cured or auto-polymerizing. The key idea is that no external energy source, like a curing light, is needed for the setting after mixing. Light-cured sealants, on the other hand, rely on light activation to polymerize, and the terms filled or unfilled describe filler content rather than how the material cures. So the two-part, mixed system is best described as self-cured materials.
