Final answer:
Zinc oxide eugenol (ZOE) is recognized for its soothing effects on dental pulp and protective qualities, but it is not the preferred base material for composite restorations as it may affect their curing process.
Step-by-step explanation:
Zinc oxide eugenol (ZOE) is often used in dentistry as a material with soothing effects on dental pulp tissue, making it beneficial for use as a base under restorations. However, it is not commonly chosen for bases under composite restorations because it may inhibit the polymerization of some composite materials. ZOE is known for its antimicrobial properties and ability to provide a protective lining to reduce thermal and chemical irritation to the pulp.
ZOE's calming effects on the pulp and its capacity to serve as an insulating layer to guard against the sensitivity that can result from dental procedures have made it a choice material for use under certain types of restorations. In addition to dental applications, zinc oxide is also prominent in medical ointments, rubber goods, and as a white paint pigment that can be marred by pollutants. Nevertheless, due to its potential to interfere with the setting of composites, alternative materials may be recommended for bases underneath composite fillings.
