Why should some cements, including zinc oxide and eugenol, be avoided for patients sensitive to eugenol?

The reason for avoiding cements such as zinc oxide and eugenol in patients sensitive to eugenol lies in the potential for allergic reactions. Eugenol, which is an active ingredient in these cements, can lead to hypersensitivity in some individuals. This sensitivity may manifest as localized irritation, allergic contact dermatitis, or other allergic reactions that can be uncomfortable or harmful to the patient.

Allergic reactions to eugenol can vary in severity and can complicate treatment outcomes, making it essential for dental professionals to be aware of a patient’s sensitivities before selecting materials. By opting for alternative cements that do not contain eugenol, practitioners can better ensure patient comfort and safety, preventing any adverse responses during or after dental procedures.
