Figure 3

Mean (standard deviation) of modulus of elasticity and biodegradation rates of dentin beams treated with different PACs, gallic acid and its derivatives and association of C1 and PGG. Different symbols represent statistical significant difference (p < 0.05). No statistically significant difference was observed between groups at baseline (p > 0.05). A1: procyanidin A1; A2: procyanidin A2; B1: procyanidin B1; B2: procyanidin B2; C1: procyanidin C1. Ga: gallic acid; MGa: methyl-gallate; PGa: propyl-gallate; PGG: penta-O-galloyl-β-D-glucose.
