Resumo
Objective: To determine the initial mechanical stabilization of conventional glass ionomer cements (GICs) indicated for the atraumatic restorative treatment (ART) in different storage periods. Material and Methods: Specimens were divided according to the GIC (n=12): IZ - Ion-Z, KM - Ketac Molar Easymix, RS - Riva Self Cure, and GL - Gold Label 9. They were prepared and stored in distilled water. Superficial microhardness (SMH) was evaluated (KHN) in three phases: (A) after 1, (B) 3, and (C) 7 days of storage. Data were submitted to 2-way ANOVA and Tukey tests (alpha = 5%). Results: The average KHN values for phases A, B, and C were, respectively, 33.05 +/- 9.74; 33.21 +/- 10.31 and 52.07 +/- 11.75 (IZ); 50.35 +/- 11.39; 66.05 +/- 10.48 and 67.77 +/- 13.80 (KM); 89.63 +/- 15.59; 71.31 +/- 23.86 and 57.70 +/- 16.89 (RS); 42.18 +/- 9.03; 68.54 +/- 6.83 and 57.95 +/- 8.24 (GL). Significant differences were observed: GIC, time, and interaction of both (p<0.05). KHN values differed between the groups, except in the GIC parameter for KM and GL. The time parameter values of phase A were lower than those of B and C, except for IZ and RS. Conclusion: The initial mechanical stabilization differed between the types of GIC tested and the storage time, and after the final period, all had similar SMH.
