What characterizes a self-cured sealant?

A self-cured sealant is characterized by its reliance on a two-part system that polymerizes quickly after being mixed. This type of sealant typically consists of a base and a catalyst that, when combined, initiate a chemical reaction leading to the hardening of the material without the need for any external energy source, such as heat or light. The promptness of this reaction allows for rapid setting, making it convenient for use in dental procedures.

The other characteristics that could potentially apply to sealants, such as the need for a heat source or activation by light exposure, are associated with other types of materials, namely heat-cured or light-cured sealants. Additionally, a self-cured sealant does indeed require a catalyst to initiate polymerization effectively, which distinguishes it from those that don’t require any catalysts. Thus, understanding the quick polymerization aspect of self-cured sealants is essential for dental assistants when selecting and utilizing intheir practices.
