Which cement is described as lacking strength and used for temporary coverage?

Zinc oxide eugenol type I is recognized for its properties that make it suitable for temporary coverage in dental procedures. This cement is characterized by its weak strength which is ideal for temporary use as it allows for easy removal when a more permanent restoration is required. It also has soothing qualities which can help alleviate sensitivity in the tooth structure underneath.

Reasons for using zinc oxide eugenol type I for temporary restorations include its ease of mixing and application, as well as its ability to create a barrier against bacteria and provide some degree of protection for the underlying tooth. This is particularly essential in scenarios where a more permanent solution will follow after a limited time, preserving the health of the tooth throughout that interim period.

In comparison, options such as glass ionomer type II and type I glass ionomer are used for more permanent applications and have better strength and adhesion properties. Composite resin is a more robust material suitable for definitive restorations rather than temporary use.
