简要总结

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

详细描述

  • 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.

结局指标

主要结局

Retention

时间窗: 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months

Retention will be assessed by visual inspection and probe to detect debonded crowns.

Fracture

时间窗: 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months

Fractures will be assessed using visual inspection to detect incomplete fracture lines or complete fractures with loss of crown material.

次要结局

  • The gingival condition(1 week, 1 month, 3 months, 6 months, 9 months, and 12 months)
