  # In a child with high caries incidence, the most appropriate cement for a band and loop space maintainer is:

A. Zinc phosphate

B. Glass ionomer

C. Zinc oxide and eugenol

D. Polycarboxylate cement

The correct answer is B. Glass Ionomer cement.

Fewer biological reactions occur with GIC than ZOE, Zinc phosphate, and zinc polycarboxylate but prolonged hypersensitivity can arise. Glass ionomer cements may be antimicrobial and, through fluoride release, provide protection against secondary caries.
