HOSA Dental Terminology Practice

A "self-cured" material in dentistry is one that undergoes a chemical reaction to harden when the components are mixed together. This type of material does not rely on external light sources or heat; instead, it creates a polymerization process that occurs due to the chemical interactions between the constituents of the material when combined.

For instance, common examples of self-cured materials include certain types of dental resins and cements that are used for fillings and prosthetics. The reaction typically involves an initiator that starts the polymerization process, leading to the setting of the material. This distinction is crucial in dental practice because it determines how the material is applied and cured, influencing the handling properties and time constraints during clinical procedures.

Other options detail characteristics that do not pertain to self-cured materials. Moisture-induced hardening relates to materials like some types of cement but does not define self-curing. While a hardening agent may be involved in various materials, self-cured materials specifically utilize a chemical reaction rather than solely relying on an agent. Lastly, refrigeration is not a necessary condition for self-cured materials; rather, it is associated with certain types of dental products to prolong shelf life but does not affect the curing process itself.
