Step-by-step explanation:
The process of changing the material from a pliable state to a hardened restoration is called curing. Curing is commonly used in the fields of dentistry and construction. In dentistry, dental restorations such as fillings, crowns, and bridges are made by placing a pliable material, such as composite resin or dental cement, into the prepared tooth and then curing it using light or heat. This causes the material to harden and become a durable restoration.
