摘要: Abstract: The aim of the present study was to evaluate fracture resis-tance teeth restored with resin composite. Forty-eight maxillary pre-molar were chosen and randomly divided six groups: G1 (con-trol): sound teeth; G2: MOD preparation, unrestored; G3: + Adper Single Bond 2 / P60; G4: Easy One G5: P90 restorative system; G6: P90. Speci-mens subjected compressive axial loading (0.5 mm/min). Flex-ural strength modulus elasticity also tested (n = 7). only statistical equivalence noted for G3 (p < 0.05). Flexural varied among com-posites 10). reestablishment resistance in premolars Class II preparations is restorative-sys-tem-dependent. silorane system not able recover fracture.Descriptors: Compressive Strength; Dentin-Bonding Agents; Dental Restoration, Permanent.
