What is the definition of "dual curing" in dental materials?

The definition of "dual curing" in dental materials refers to the process where curing occurs through both a chemical reaction and light exposure. This means that the material can harden and set not only when activated by light, such as a dental curing light, but also through a chemical reaction that takes place independently of any light source.

This capability is particularly beneficial in dental applications where complete curing is essential to ensure the material's strength and durability, especially in areas that may not be easily accessible to light. Dual-cure materials provide versatility for the dentist and are advantageous in situations where exposure to light is limited, ensuring optimal results for restorations and other dental procedures.
