Flexural Properties and Elastic Modulus of Different Esthetic Restorative Materials: Evaluation after Exposure to Acidic Drink

Table 2

Mean values (and standard deviations) of flexural strength (MPa). Values have been collected after storage in physiologic solution (Subgroup A, t0), after one week (Subgroup B, t1), and after 30 days (Subgroup C, t2) of immersions in acidic drink.
