Interfacial Stress and Bond Strength of Bulk-Fill or Conventional Composite Res...
Duarte,Júlio César Lemos; Costa,Ana Rosa; Veríssimo,Crisnicaw; Duarte,Renata Webster; Calabrez Filho,Saturnino; Spohr,Ana Maria; Borges,Gilberto AntonioAbstract The aim was to evaluate the microtensile bond strength (mTBS) to dentin and interfacial stress in a class II cavity restored with bulk-fill or conventional composite resins and the margin interfaces. Vertical slot class II cavities in the mesial face, with the gingival end in dentin, were prepared in 72 third molars, being divided into groups (n=24): G1-Tetric N-Ceram; G2-Tetric N-Ceram Bulk-Fill; G3-S...
Effect of Dentin Preparation Mode on the Bond Strength Between Human Dentin and...
Cerqueira,Lara Almeida Cyrillo; Costa,Ana Rosa; Spohr,Ana Maria; Miyashita,Eduardo; Miranzi,Benito André Silveira; Calabrez Filho,SaturninoAbstract The aim was to evaluate the influence of different dentin preparation mode in the smear layer characteristics (SL), hybrid layer (HL), and microtensile bond strength (µTBS) to dentin with two resin cements. The occlusal dentin of 120 third molars was exposed. The teeth were divided into 4 groups (n=30) according to the dentin preparation mode: 1- fine grain diamond bur; 2- coarse grain diamond bur; 3- ...
