Abstract

Statement of the Problem: During the orthodontic treatment, microbial plaques may accumulate around the BRACKETs and cause caries, especially in high-risk patients. Finding ways to eliminate this microbial plaque seems to be essential.Purpose: The aim of this study was to compare the antibacterial effects of nano copper oxide (CuO) and nano zinc oxide (ZnO) coated BRACKETs against STREPTOCOCCUS MUTANS (S.mutans) in order to decrease the risk of caries around the orthodontic BRACKETs during the treatment.Materials and Method: Sixty BRACKETs were coated with nanoparticles of ZnO (n=20), CuO (n=20) and CuO-ZnO (n=20). Twelve uncoated BRACKETs constituted the control group. The BRACKETs were bonded to the crowns of extracted premolars, sterilized and prepared for antimicrobial tests (S.mutans ATCC35668). The samples taken after 0, 2, 4, 6 and 24 hours were cultured on agar plates. Colonies were counted 24 hours after incubation. One-way ANOVA and Tukey tests were used for statistical analysis.Results: In CuO and CuO-ZnO coated BRACKETs, no colony growth was seen after two hours. Between 0-6 hours, the mean colony counts were not significantly different between the ZnO and the control group (p>0.05). During 6-24 hours, the growth of S.mutans was significantly reduced by ZnO nanoparticles in comparison with the control group (p< 0.001). However, these bacteria were not totally eliminated.Conclusion: CuO and ZnO-CuO nanoparticles coated BRACKETs have better antimicrobial effect on S.mutans than ZnO coated BRACKETs.
