    The present study evaluated the erosive influence of tucupi on the resistance of the adhesive bond to enamel and dentin. 168 healthy bovine incisors teeth were used, divided into 12 groups (n = 14). For erosive cycling, distilled water (negative control), cola-based soft drink (positive control) and tucupi were used. The adhesive strategies used were: (1) total acid conditioning (conventional) and (2) self-conditioning. All specimens were subjected to cycling with the drinks described above for 5 days and, after 24h of the 5th day, composite resin cylinders were made for the micro shear resistance test. The data showed normal distribution and were analyzed by two-way ANOVA, followed by the Tukey post-test (p≤0.05). There were no significant differences in enamel (p>0.05). In dentin, only the groups exposed to cola-based soft drink showed significant differences (p<0.01). The erosive challenge with tucupi did not influence the bond strength to enamel and dentin, independent of the adhesive strategy used.
