Objective: The objective of the study was to assess the efficiency of an antibacterial monomer-containing adhesive in the reduction of white-spot lesions (WSLs) around orthodontic brackets (in vivo) in comparison to the conventional adhesive systems. Materials and Methods: This study was conducted on twenty patients, provided that they required the extraction of the maxillary first premolars as part of their orthodontic treatment plan. This involved only on the maxillary first bicuspids (n = 40) and the left maxillary first premolars represented the control side (n = 20) where the metal brackets (3M, Unitek™ Gemini) were bonded to that side using Transbond XT light cure adhesive (3M, Unitek). Meanwhile, the right side represented the experimental one (n = 20) and the brackets were bonded to them using Clearfil SE protect (Kuraray). After 3 months, both teeth were extracted and examined by both the energy-dispersive X-ray spectroscopy to assess the calcium and phosphorus atomic percentages were assessed in the area surrounding the bracket by and the scanning electron microscopy to evaluate the morphology and crystalline structure of the tooth surfaces. Results: A significant difference between the antibacterial monomer-containing adhesive and the conventional adhesive system in the prevention of the WSLs formation was evident in the study. Moreover, the difference in the enamel surface morphology was noted. Conclusions: Antibacterial monomer-containing adhesive can minimize demineralization around the metal brackets (in vivo) compared to the conventional one after a period of 3 months.
