HESI General Chairside Assisting Practice Exam

Which dental material is compatible with all types of restorative materials?

1. Glass ionomer

2. Composite resin

3. Calcium hydroxide

4. Amalgam

The correct answer is: Calcium hydroxide

Calcium hydroxide is known for its compatibility with various types of restorative materials. Its unique chemical properties, primarily its ability to stimulate reparative dentin formation and provide a suitable environment for bonding, make it a preferred choice when it interacts with other materials. Calcium hydroxide is commonly used as a liner under restorative materials due to its biocompatibility and ability to promote healing in the dental pulp. It works well with glass ionomer, composite resins, and amalgams, allowing these materials to adhere effectively without causing adverse reactions. This compatibility is crucial in dental procedures, as it ensures the longevity and success of the restoration while maintaining the health of the tooth structure beneath. Other materials, while effective in their specific applications, may not exhibit the same broad compatibility. For example, glass ionomer and composite resins are more limited in terms of the materials they can effectively bond to, while amalgam has its specific protocols and interactions based on the materials used in conjunction with it. Therefore, calcium hydroxide stands out as the material that can be safely used with all types of restorative materials in dentistry.
