Post crown cementation sensitivity is primarily caused by what?

• A. Misalignment
• B. Microleakage
• C. Improper cleaning
• D. Infection

Answer: (B)

Post crown cementation sensitivity is primarily caused by microleakage. This phenomenon occurs when there are gaps between the crown and the tooth structure, allowing dental fluids and bacteria to penetrate the interface. Such leakage can lead to the exposure of the underlying dentin or pulp to irritants, resulting in discomfort or pain after the crown is placed. Microleakage can be influenced by several factors, including the quality of the crown fit, the cement used, and the bonding technique. If microleakage is present, it may lead to thermal sensitivity, an increase in bacterial colonization, or even secondary caries development, all of which can compromise the health of the tooth and contribute to patient discomfort. Other factors, such as misalignment, improper cleaning, or infection, may contribute to sensitivity in some scenarios, but they are less common causes in the context of post-cementation sensitivity. Misalignment may lead to occlusal issues, improper cleaning might affect the bonding process, and infection usually arises from pre-existing conditions rather than the cementation procedure itself. Thus, understanding microleakage is crucial for diagnosing and addressing sensitivity following crown placement.
