Objective: To evaluate the effect of adhesive application on the shear bond strength (SBS) of orthodontic tubes to acid-etched human enamel using different temperatures and orthodontic composite resins. Methods: One hundred and twenty metal tubes were bonded to human third molars, which were randomly divided into three groups depending on the composite used: Transbond XT (XT); Transbond Supreme LV (LV); and Light Bond (LB). Each group was divided into four subgroups depending on the temperature (5 degrees, 20 degrees, 40 degrees, and 60 degrees) applied to the composite before cementing. For each experimental subgroup, half the specimens were bonded in combination with XT Primer. After 72h, a SBS test was performed using a universal testing machine. Statistical analysis was performed using ANOVA, post hoc intergroup comparisons, chi-square test, and linear regression. Two representative molar surfaces from each subgroup were assessed under Scanning electron microscope. Results: The composite type only influenced XT regarding LB. The use of adhesive does not affect the SBS values of any composite. The flowable composites with adhesive containing zirconia (LV) as a filler showed lower SBS when cooled to 5 degrees C and when increases the temperature from 40 degrees C. Whether adhesive was used or not, composites with silica as filler (LB) showed lower SBS at 60 degrees C and increased to 5 degrees C. Conclusions: For all composites, from 20 degrees C, SBS values tend to increased and started to decline at 40 degrees C except when adhesive is applied to the quartz-filled composite, which continues to increase, and the silica-filled composite without adhesive, which tend to decreases from 5 degrees C.
