Final answer:
Zinc Oxide Eugenol (ZOE) is used as a dental base due to its sedative effects on the dental pulp, antimicrobial properties, insulating abilities, and its role as a thermal barrier providing protection and support for healing.
Step-by-step explanation:
Zinc Oxide Eugenol (ZOE) is widely used as a base in various applications, particularly in dentistry, because of its unique properties. ZOE exhibits sedative effects on the dental pulp, helps to insulate and protect the tooth, and possesses antimicrobial properties, making it suitable for use as a temporary filling or a permanent dental cement. Its application extends to serving as a base under restorations or deep fillings where it provides a thermal barrier and protective layer for the dental pulp. In addition, ZOE also has a neutral pH and a high degree of biocompatibility which supports healing and is appreciated in dental procedures.
