National Dental Assisting Examining Board (NDAEB) Practice Exam

Which quality is NOT associated with Calcium Hydroxide?

1. Protects pulp from chemical irritation

2. Stimulates the production of secondary dentin

3. Increases sensitivity of the tooth

4. Compatible with all types of materials

The correct answer is: Increases sensitivity of the tooth

Calcium hydroxide is primarily known for its role in endodontics and various restorative procedures, where it provides important benefits to dental tissues. It is recognized for its protective qualities, including its ability to shield the pulp from chemical irritation, which can be caused by dental materials used during procedures. This protective mechanism helps maintain the health and integrity of the pulp tissue. Additionally, calcium hydroxide stimulates the production of secondary dentin, a process crucial for maintaining the vitality of the tooth when the pulp is under threat. This substance encourages the dental pulp to adapt and respond to various challenges during treatment. While calcium hydroxide exhibits many beneficial properties, it is not associated with increasing the sensitivity of the tooth. In fact, one of its functions is to provide a barrier that aids in reducing sensitivity following procedures that may otherwise leave the pulp exposed or vulnerable to irritants. Furthermore, it is noted for its compatibility with numerous materials used in dentistry. While it's important to consider specific interactions with certain materials in clinical settings, it is generally accepted that calcium hydroxide can be used in conjunction with a variety of restorative materials without causing adverse reactions. Thus, the quality of increasing tooth sensitivity does not align with the established benefits and characteristics of calcium hydroxide in dental practice.
