Italy), and after 2 minutes of activation, following the manufacturer's instructions, the gel started to modify its consistency, producing oxygen bubbles. Its color changed from translucent green to light grey, and at this phase, a dentine excavator (ASA Dental, Bozzano, Italy) was used to remove the altered tissue (Figure 4).
