Which component is combined with zinc oxide in root canal cementing materials?

Calcium hydroxide
Hydrogen peroxide
Eugenol
Glycerin

The correct answer is: Eugenol

The combination of zinc oxide with eugenol is a well-established practice in root canal cementing materials. Eugenol is an essential component that enhances the material's properties, making it suitable for dental applications. When mixed with zinc oxide, eugenol forms a paste that has anti-inflammatory, analgesic, and antimicrobial properties, which are crucial during the root canal treatment process. This combination helps to seal the root canal effectively, preventing bacterial leakage and promoting healing in the surrounding tissues. Other components mentioned, such as calcium hydroxide, hydrogen peroxide, and glycerin, serve different functions in dentistry. Calcium hydroxide is often used for pulp capping or as an antimicrobial agent, while hydrogen peroxide is primarily used for its bleaching properties or as an antiseptic. Glycerin is typically used as a lubricant or humectant but does not serve the same critical function when combined with zinc oxide for cementing purposes in root canals. This specificity of eugenol's role distinguishes it as the correct choice in this context.
