ABSTRACT

BACKGROUND:

TiO2-xNx film has good antibacterial effects on Streptococcus mutans, Actinomyces viscosus and Candida albicans.

OBJECTIVE:

To investigate the antimicrobial property of TiO2-xNx bracket.

METHODS:

Ten orthodontic patients were selected, and their teeth were divided into two parts by oral midline and respectively treated with ordinary metal brackets and TiO2-xNx bracket. Orthodontic plaque index, gingival index, gingival sulcus bleeding index and enamel demineralization index were detected before, and at 1, 2, 3, 4 weeks after orthodontic treatment. RESULTS AND

CONCLUSION:

For the ordinary metal brackets, the orthodontic plaque index, gingival index, gingival sulcus bleeding index and enamel demineralization index were al increased after orthodontic treatment (P < 0.05); for the TiO2-xNx bracket, the gingival index was increased at 3 weeks after treatment (P < 0.05), the gingival sulcus bleeding index was increased at 1, 2, 3 weeks after treatment (P < 0.05), and the enamel demineralization index was increased at 2, 3, 4 weeks after treatment (P < 0.005). Compared with the ordinary metal brackets, the orthodontic plaque index and gingival sulcus bleeding index were lower in the TiO2-xNx bracket group at 1-4 weeks after treatment (P < 0.05), and the gingival index and enamel demineralization index were lower in the TiO2-xNx bracket group at 2-4 weeks after treatment (P < 0.05). These findings indicate that the TiO2-xNx film bracket has excelent antibacterial properties, which is better to control and removal dental plaques.
