What type of material is typically used with a linear applicator during cavity preparations?

1. Composite resin

2. Calcium hydroxide or glass ionomer

3. Amalgam filling

4. Temporary filling material

The correct answer is: Calcium hydroxide or glass ionomer

The type of material typically used with a linear applicator during cavity preparations is calcium hydroxide or glass ionomer. These materials serve as lining agents in dental procedures. Calcium hydroxide is known for its properties that promote the formation of secondary dentin and help protect the pulp by providing thermal insulation and minimizing bacterial infiltration. Glass ionomer, on the other hand, offers a strong bond to tooth structure and releases fluoride, which can aid in the remineralization of adjacent tooth surfaces. Together, these materials are commonly used in cavity preparations to manage the tooth structure and provide a suitable base or lining before the final restoration is placed. This approach is crucial in ensuring the long-term success of the restoration more than other materials would, such as composite resin, which is primarily used for the final restoration, or amalgam, which is also not typically used as a liner. Temporary filling material is usually applied as a temporary measure and is not intended for use during the preparation stage of cavity restoration.
