Zinc oxide eugenol is not suitable for use with resin restorations because its chemical composition can interfere with the bonding process of resin materials. Resin restorations rely on a strong chemical bond to the underlying tooth structure, and eugenol, a component of zinc oxide eugenol, can inhibit the polymerization of resin materials. This leads to compromised bond strength and durability of the restoration.

In contrast, other materials like zinc phosphate, calcium hydroxide, and glass ionomer can be used effectively with resin restorations. Zinc phosphate provides a strong base, calcium hydroxide promotes dentin healing and can enhance bonding by creating a favorable environment, and glass ionomer can also bond well with resin and release fluoride, which is beneficial for tooth health.
