ABSTRACT
AIM:
To investigate the effects of titanium dioxide(TiO2)nanotube arrays on the early adhesion behavior of Porphyromonas gingivalis(Pg),Tannerella forsythia(Tf)and Actinobacillus actinomycetemcomitans(Aa)be-fore and after loaded with minocycline hydrochloride(MN).METHODS:
TiO2nanotube arrays were prepared by ano-dization and loaded with MN.Titanium slices were divided into 3 groups according to different treatmentmethods:
pure polishing titanium(Ti)group,TiO2nanotube titanium(TiO2)group, and MN(120 μg)TiO2nanotube titanium(MN TiO2)group.The antibacterial properties of the titanium tablets were evaluated by the bacteriostasis test.RESULTS:
The Ti had no antibacterial activity.The antibacterial activity of TiO 2to Aa,Pg and Tf was poor,with only about 20%of anti-bacterial rate after 4 h.After loaded with MN,its antibacterial activity was enhanced,and the antibacterial rate was up to 77%after 4 h.CONCLUSION:
No antibacterial activity in the Ti group was observed.If TiO2nanotube arrays were formed on the surface and MN was loaded,the antibacterial activity on periodontal pathogens was stronger.
