مستخلص: Introduction: The goal of this research was to experimentally evaluate the surface morphology and adhesion capacity of Streptococcus mutans (U159) on brackets with thin films of titanium nitride (TN) and of titanium nitride doped with calcium phosphate (TNCP).
Methods: Twenty-four metallic brackets were equally allocated to 3 groups (n = 8), according to the type of covering (no covering, TNCP, and TN). The coatings were deposited by cathodic cage (TNCP and TN groups) and were evaluated by scanning electron microscopy and energy dispersive x-ray spectrometry. The biofilm formation of S. mutans on the surface of brackets was determined by crystal violet assay and subsequent optical density quantification.
Results: There was homogeneity on the surface morphology of the tie wing area in all groups, whereas the TNCP group has presented particles in the slot. After 24 hours, a biofilm of S. mutans was formed in all the observed groups. The optical density obtained in all 3 groups was similar (no covering, 0.347 ± 0.042; TNCP, 0.238 ± 0.055; TN, 0.226 ± 0.057), with no statistically relevant difference (P = 0.06).
Conclusions: The thin film of TNCP has altered the surface of the bracket's slot, whereas the coatings of TN and TNCP have not altered the superficial morphology of the tie wings. The presence of coatings have not influenced the formation of the S. mutans biofilm on the surface of metallic brackets.
