Study Arms (3)

Dentin Conditioning & RM-GIC

ACTIVE COMPARATOR

Dentin Conditioning: After washing and drying -but not desiccating- Dentin Conditioner 20% (GC, Japan) will be applied using a cotton pellet for 20 seconds then rinsed thoroughly and gently dried. RM-GIC: RM-GIC (Fuji II LC) will be applied in \<2mm incremental layers afterward light-cured for 10 sec (1,000 mW/cm2) per increment to fill the cavity.

Other: Dentin ConditioningOther: RM-GIC

1-step adhesive & Cention N

EXPERIMENTAL

1-step adhesive: A universal adhesive system (Tetric® N-Bond Universal) will be applied on both enamel and dentin and gently scraped for 20 sec, then dispersed with oil-free gentle air stream, then light-cured for 10 sec (1,000 mW/cm2). Cention N: The cavity will be restored using cention N followed by light curing for 10sec (1,000 mW/cm2)

Other: 1-step adhesiveOther: Cention N

Dentin roughness & Gingival retentive groove preparation & Cention N

EXPERIMENTAL

Dentin roughness: Using a round carbide bur size 14/16, (H1SEM.204.014 VPE5 or H1SEM.204.016 VPE 5, Komet Dental, Lemgo, Germany) on a low-speed handpiece. (No bevel preparation will be made) Gingival retentive groove preparation: Using size-010 round carbide bur (H1SEM.205.010 VPE 5, Komet Dental, Lemgo, Germany) on a low-speed handpiece. Cention N: The cavity will be restored using cention N followed by light curing for 10sec (1,000 mW/cm2)

Other: Cention NOther: Dentin roughnessOther: Gingival retentive groove preparation
