Which type of cement is inappropriate for use in provisional coverage?

Zinc phosphate
Glass ionomer cement
Temporary cement
Resin-modified glass ionomer

The correct answer is: Zinc phosphate

Zinc phosphate cement is primarily used for more permanent applications due to its strength and durability, making it unsuitable for provisional coverage, which requires materials that can be easily removed and do not put undue stress on the underlying structures. Provisional coverage serves a temporary function, allowing the patient to maintain dental aesthetics and function while awaiting a more permanent restoration. Temporary cements are specifically formulated for this purpose, providing the ideal balance between retention and ease of removal. Glass ionomer cements and resin-modified glass ionomer cements also serve as suitable options for provisional coverage, as they can bond to tooth structures and release fluoride, offering some level of protection to the tooth underneath while remaining easy to remove when necessary.
