Study: NCT02286388

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: A one-step partial caries removal procedure for the treatment of deep carious lesions in posterior permanent teeth.
Description: Instruments and procedures:~* Soprolife® (Acteon, La Ciotat, France) dental imaging device to detect dentinal infection status. The green-black light indicates infected dentin, red indicates infected/affected dentin and green indicates healthy dentinal tissue.~* Sterile round bur under water spray coolant followed by final excavation with hand instruments The clinician will remove the superficial necrotic and demineralized dentin with complete excavation of the peripheral demineralized dentin, avoiding excavation close to the pulp.~Hand instruments will be used for final excavation following clinical criteria guidelines (color of residual dentin and probe resistance) and taking in to consideration the color data obtained by the Soprolife® camera.~The operator will stop excavating when the dentin close to the pulp appears red (for infected dentin).

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: The application of an antibacterial dental adhesive (ClearfilTM SE Protect, Kuraray Dental).
Description: Enamel and dentin will be conditioned according to the manufacturer's instructions. Both antibacterial and conventional adhesives are two-steps bonding systems.~The first step consists of the application of a primer to the enamel and dentin for 20 seconds (which allows the completion of etching and priming procedures). The second step consists of the application of the antibacterial adhesive and its light curing for 10 seconds.
