A female patient reports an allergic reaction when wearing certain types of jewelry. Which agent should be reduced in the fabrication of her new crown for tooth #30?

In the scenario described, the patient experiences an allergic reaction to certain types of jewelry, which often correlates with sensitivity to nickel. Nickel is a common alloying metal used in dental materials, particularly in some types of crowns and fillings. It is known for its strength and affordability but can provoke allergic reactions in sensitive individuals.

When fabricating a new crown for the patient, it is important to consider her known allergy. Reducing or eliminating nickel in the crown material would help to prevent any possible allergic reactions during or after the crown placement. Other materials, such as gold, palladium, and copper, are less commonly associated with allergic responses and are often well-tolerated by most patients.

Therefore, selecting a crown material that minimizes or prevents exposure to nickel is essential in ensuring the patient's comfort and safety. This adjustment will significantly contribute to positive clinical outcomes and patient satisfaction.
