Selective removal to soft dentin (SRSD)
Selective removal to firm dentin (SRSD)
The patients in SRSD group will be randomized into two subgroups as Group A and Group C. After caries removal to soft dentin calcium silicate based material (Biodentine) will be applied in Group A while will not be applied in Group C prior to placement of the resin composite restoration. The procedure, starts with access to caries tissue by the removal of surrounding unsupported enamel.Carious tissue at the periphery of the cavity will be prepared to hard dentin using round tungsten carbide burs and/or an excavator, while soft carious dentin will remain in the pulpal aspect of the cavity to prevent pulp exposure. Operative procedures will be performed by an experienced (over 10 years) specialist. Moisture control will be provided using cotton rolls and continuous aspiration.
Procedures will be done using local anesthesia. The procedure, starts with access to caries tissue by the removal of surrounding unsupported enamel. Caries tissue in the periphery including the enamel-dentinal junction will be removed using round tungsten carbide burs and/or an excavator until hard, dry dentin remains. Pulpo-proximal caries tissue will be removed until hard or leathery dentin remains. Operative procedures will be performed by an experienced (over 10 years) specialist. Moisture control will be provided using cotton rolls and continuous aspiration. Restoration will be performed after caries removal to firm dentin and placement of calcium silicate based material (Biodentine).
