0.05. Results: The Control group's shear bond strength was statistically higher than that of the other groups (16.1 MPa for the control group and 12.9 MPa, 10.8 MPa for luteolin 1% and Luteolin 3%, respectively). However, the SBS results of this study demonstrated that the mean of all groups was more than that recommended by Reynolds (5.9-7.8 MPa) in (1975). The disc diffusion method showed that 3% luteolin modified adhesive was more effective than luteolin 1% and the control groups, with a larger bacterial inhibition zone. Conclusions: The incorporation of Luteolin NPs in orthodontic resin produced an antibacterial effect againstStreptococcus mutans and Lactobacillus acidophilus without compromising the shear bond strength.]]>
