Overview

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

* 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.

Zirconia crown cemented with Predicta® Bioactive CementDRUG

• 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.

Zirconia crown cemented with resin-cementDRUG

• 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.

Inclusion Criteria: * Patients who had no history of allergies * Children who had at least two carious primary incisors. * Teeth with multi-surface carious lesion. * Teeth with no percussion or palpation sensitivity * Teeth with no abscess and/or fistula * Teeth with no prior pulpal treatment * Teeth with no mobility or signs of periodontal disease Exclusion Criteria: * Children with congenital developmental defects (such as amelogenesis imperfecta and dentinogenesis imperfecta) * Children with a history of bruxism, trauma or infraocclusion * Children with a skeletal or dental malocclusion

Outcomes

Primary Outcomes

Retention

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

Time frame: 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months

Fracture

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

Time frame: 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months

Secondary Outcomes

The gingival condition

The gingival condition around cemented crowns will be assessed by calculating the gingival index for each crowned tooth.

Time frame: 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months
