For a patient with tooth sensitivity to cold receiving a PFM crown, what is the cement of choice?

In the context of a patient experiencing tooth sensitivity to cold undergoing the placement of a porcelain-fused-to-metal (PFM) crown, polycarboxylate cement is the most suitable choice. This cement is known for its biocompatibility and its ability to provide a significant amount of thermal insulation. For patients with sensitivity, especially to cold stimuli, using polycarboxylate can help reduce the risk of further discomfort after the crown placement.

Polycarboxylate cement has good adhesion to both tooth structure and the metal substructure of the crown, which enhances its effectiveness. Additionally, its relatively low film thickness allows for a more accurate fit and marginal integrity around the crown, which is crucial for preventing further sensitivity and ensuring a long-lasting restoration.

In contrast, while other materials like glass ionomer cement are also considered for their good properties, they may not offer the same level of thermal insulation and could lead to sensitivity in certain cases. Zinc phosphate, although a strong option, can be irritating to the pulp and is less suitable for sensitive patients. Zinc silicone phosphate has limitations in terms of adhesion and use in cementing crowns on potentially sensitive teeth. Thus, polycarboxylate cement is indeed the preferred option for reducing sensitivity while ensuring a
