Study Groups

1
Partial removal of carious dentine. Carious dentine partial removal plus restoration in one session. The group is divided according to the filling material: amalgam or resin.
Partial removal of carious dentine
All procedures will be carrying out under local anesthesia and rubber dam. The treatment will be performed as follow: access to the lesion using rotator instruments (if necessary); fully removal of carious tissue from the cavity walls according to hardness criteria by rotator instruments and/or hand excavator; removal of the necrotic carious tissue (soft and disorganized carious tissue) from the cavity floor by hand excavator (to avoid pulp exposure); cleaning with distilled water and drying with sterile filter paper; group randomization. If the tooth is assigned to test group: cavity floor covered with calcium hydroxide cement; restoration using amalgam or steel crown following their usual clinical procedures based on the instructions of the manufacturer
2
Stepwise excavation: Carious dentine removal performed in 2 steps: partial removal of carious dentine, indirect pulp capping (calcium hydroxide cement); temporary filling with IRM; cavity re-opening after 60 days, removal of the remaining soft carious tissue and filling (amalgam or resin).
Stepwise excavation
The treatment will be performed as follow: access to the lesion using rotator instruments (if necessary); fully removal of carious tissue from the cavity walls according to hardness criteria by rotator instruments and/or hand excavator; removal of the necrotic carious tissue (soft and disorganized carious tissue) from the cavity floor by hand excavator (to avoid pulp exposure); cleaning with distilled water and drying with sterile filter paper; group randomization. If the tooth is assigned to SE: indirect pulp capping with calcium hydroxide cement; temporary filling with IRM; cavity re-opening after 60 days, removal of the remaining soft carious tissue and filling following the same procedures described to test group.
