T The adhesive material is an intermediate for the attachment of the composite resin to the tooth structure. The adhesive material is divided into two broad categories, namely total-etch and self-etch systems. The total-etch system requires the application of acid etching to form the small porosity in which the adhesive material enters as mechanical retention The self-etch system uses primary acid to modify the smear layer. The composite resin bond to the dentine tissue requires adhesive material and laboratory parameters that are often used to measure the bond is a shear bond test. Objective: to know' the difference of adhesive matenal of fifth and eighth generation to the strength value of shear bond strength composite resin-dentin. Method: 10 premolar teeth that are caries free and revoked for reasons of orthodontic treatment cleaved longitudinally with the bucco-palatal direction to obtain 20 samples of tooth pieces. The maxillary premolar teeth were divided into 2 groups. The first group used the fifth generation adhesive material (Adper Single-bond 2, 3M), the second group used the eighth generation adhesive (Futurabond U. VOCO). The composite resin used is a type of nanofil (FiltekTM Z350XT, 3M). Composite resin samples then incubated with 37°C for 24 hours and 100% humidity . Samples were tested with a Universal Testing Machine with a speed of 0 5mm/min and a maximum load of 50kgf. Results: Independent parametric test T-test showed significant difference between the two groups of adhesive materials (p> 0.05). The mean shear strength values for the fifth and eighth generation adhesives are 6,96+0,68 and 8,91+0,58. Conclusions: There was rio significant difference between 5th and 8lh dental adhesive on the strength value of the dentine-composite resin shear strength.
