What cement can be used as a base and obtundant for dental procedures?

Zinc oxide eugenol is recognized for its properties that make it suitable as a base and obtundant in dental procedures. It has a soothing effect on the pulp due to the eugenol content, which helps in reducing inflammation. This property is particularly beneficial when it is used in deep cavity preparations where the pulp may be sensitive or exposed. The cement also has good sealing abilities and can provide thermal insulation, which helps in protecting the pulp from thermal irritants.

Additionally, zinc oxide eugenol can be used with a variety of restorative materials and serves as an effective barrier against bacteria, reducing the likelihood of postoperative complications. Its ease of manipulation and ability to set quickly under moisture are also advantageous in clinical settings. These combined properties make zinc oxide eugenol an ideal choice for dentists when selecting a cement for bases and obtundants in restorative dentistry.

In comparison, while other options like zinc phosphate, glass ionomer, and calcium hydroxide also have their own uses in dental applications, they may lack some of the specific soothing properties and sealing capabilities that zinc oxide eugenol offers, making it the more effective choice in this context.
