Step-by-step explanation:
Indirect pulp capping is a dental procedure used to treat deep cavities that are close to the pulp without exposing it. The success of indirect pulp capping is dependent on several factors. It is important to remove all caries at the enamel-dentin junction to ensure that the cavity is properly cleaned. The use of calcium hydroxide as a liner or base is also beneficial as it promotes dentin repair and protects the pulp. Additionally, a well-sealed restoration is necessary to prevent the entry of bacteria and further decay.
