Summary

The study aims to compare the efficacy of using bioactive cement versus resin-cement for cementation of anterior pediatric zirconia crowns.

Detailed description

* For the bioactive cement group (Predicta® Bioactive Cement), the prepared tooth will be dried using compressed air but not desiccated. Cement will be dispensed through the auto-mixtip directly into the crown, and the crown will be properly positioned over the tooth; cement will be allowed to self-set for 20 seconds while maintaining gentle pressure on the crown. Buccal and lingual margins will be flash-cured for 10 seconds each using a light-curing unit to immediately cure the excess cement for easier removal, and buccal and lingual surfaces will then be light-cured for an extra 10 seconds each. * For the resin-cement group, the tooth will be dried with compressed air but not desiccated. The sealant will be applied with the syringe; then, the crown will be appropriately positioned over the tooth, and cement will be allowed to self-set for 2 minutes and cured while maintaining gentle pressure on the crown. Excess cement will be removed before the cement is completely set.
