From: Preventive effect of a high fluoride toothpaste and arginine-carbonate toothpaste on dentinal tubules exposure followed by acid challenge: a dentine permeability evaluation

Figure 2

Experimental design. The specimens were divided into 3 groups (G1- Negative control; G2 – Duraphat® 5000 toothpaste; G3 – Colgate® Pro-Relief. Dentine permeability evaluation was performed at baseline (Stage 1); after 37% phosphoric acid application (Stage 2); after treatment (Experimental Groups- Stage 3); after erosion (Stage 4).
