What does ZOE stand for in dental materials?

  1. Zinc oxide-eugenol

  2. Zinc orthophosphate-eugenol

  3. Zinc oxide-ethylmethacrylate

  4. Zirconium oxide-eugenol

The correct answer is: Zinc oxide-eugenol

ZOE stands for Zinc oxide-eugenol, which is a common dental material known for its unique properties. This material is largely used in dental procedures due to its effective pain relief capabilities and excellent sealing properties. Zinc oxide serves as the primary component, while eugenol, which is derived from clove oil, adds analgesic and antibacterial effects, making ZOE particularly useful in temporary fillings and as a base under dental restorations. Its biocompatibility makes it a preferred choice for many dental applications, especially in procedures involving sensitive pulp tissues. The other options mentioned, such as Zinc orthophosphate-eugenol or Zirconium oxide-eugenol, do not accurately represent the widely recognized abbreviation ZOE in the context of dental materials. Each of those alternatives refers to different compounds that lack the specific combination of zinc oxide and eugenol that defines ZOE.
