Study Arms (2)

Bio-active cement

EXPERIMENTAL

Bio-active cement dispensed into the crown, and the crown was properly positioned over the tooth, cement was allowed to self-set for 20 seconds while maintaining gentle pressure on the crown, then flash cured using a light curing unit to remove excess cement, buccal and lingual surfaces were light cured for extra 10 seconds each.

Drug: Bio-active cement

Packable glass ionomer

ACTIVE COMPARATOR

Dentin conditioner was applied to the prepared crown surfaces for 20 sec, then rinsed, and dried. Capsule was activated, mixed for 10 seconds in an amalgamator, then loaded into the capsule applier to extrude cement directly into the crown, the crown was properly positioned over the tooth, cement was allowed to self-set for 2 minutes while maintaining gentle pressure on the crown, excess cement was removed before complete setting of cement.

Drug: Packable glass ionomer

Interventions

A cement used for crown cementation, specially recommended for pediatric esthetic crowns

Also known as: Bio-cem
Bio-active cement

Glass ionomer cement with improved mechanical properties usually used for restoration of simple small cavities and in Atraumatic Restorative Treatment

Also known as: Fuji IX, High viscosity glass ionomer
Packable glass ionomer
