What is one of the main uses of zinc oxide and eugenol?

Zinc oxide and eugenol is primarily known for its use as a temporary filling material due to its properties that facilitate effective sealing and provide comfort to the patient, especially after dental procedures. Its unique formulation offers a soothing effect on the dental pulp, which is particularly beneficial in cases where the pulp may be sensitive or inflamed.

This material helps to preserve the integrity of the tooth while providing a barrier against further decay or potential irritation from thermal stimuli. The use of zinc oxide and eugenol in temporary fillings allows for a suitable interim solution while a more permanent restoration can be placed later, showcasing its purpose in dental practice effectively.

The other choices do not appropriately reflect the main use of zinc oxide and eugenol, as it is not primarily intended for functions like root canal sealing, permanent cementation, or composite bonding. Each of those applications typically utilizes different materials specifically designed to meet the required properties and long-term durability.
