The aim of this study was to evaluate the bond strength of a self-etching adhesive system on teeth subjected to Co-60 irradiation. Thus, 24 human third molars were selected. Of these, 12 were randomly selected and exposed to total radiation of 1935,588 cGy (corresponding to the effective biological dose of 35 daily cycles of 2000 cGy). The teeth were prepared by removing the occlusal enamel, exposing a flat dentin surface. The Single Bond Universal Adhesive System (3M/ESPE) was applied to each group according to the manufacturer's instructions. Then, two resin increments, of 2 mm each, of composite resins Filtek Z350 XT (3M/ESPE) or Aura (SDI) were added, which were light cured for 20s. There were, therefore, four analysis groups: Aura + irradiated Universal Single Bond (ASBI), Aura + non-irradiated Universal Single Bond (ASBNI), Filtek Z350 + irradiated Universal Single Bond (FZSBI) and Filtek Z350 + irradiated Universal Single Bond (FZSBNI). The samples were sectioned, yielding toothpick-shaped specimens. To evaluate the bond strength, a microtensile test was performed using the EMIC DL - 2000 machine (EMIC, Brazil) with a load cell of 500N and a microtensile speed of 0.5 mm/min. Although the radiation doses applied may cause some structural changes in the dentin, this did not interfere with the bond strength of teeth that were or were not exposed to radiation and that were restored using a self-etching adhesive system. No statistically significant difference was found in the bond strength between the groups, whether comparing the irradiated and non-irradiated groups, or between the different resins used: ASBI (35.76 Mpa), ASBNI (34.32 Mpa), FZSBI (32.20 Mpa) and FZSBNI (38.37 Mpa).
