摘要:

 背景:有研究表明TiO2-xNx薄膜对变形链球菌、黏性放线菌及白色念珠菌具有良好的抗菌效果。

目的:进一步评价TiO2-xNx薄膜托槽的抗菌性能。 

方法:纳入10例正畸患者,将口内牙齿以上下中线分为左右两侧,分别粘接普通金属托槽和TiO2-xNx薄膜托槽,在矫治前、矫治后1,2,3,4周检测正畸菌斑指数、牙龈指数、龈沟出血指数及釉质脱矿指数。

结果与结论:普通金属托槽组矫治后1,2,3,4周的正畸菌斑指数、牙龈指数、龈沟出血指数及釉质脱矿指数均高于矫治前(P < 0.05);TiO2-xNx薄膜托槽组矫治后3周的牙龈指数高于矫治前(P < 0.05),矫治后1,2,3周的龈沟出血指数高于矫治前(P < 0.05),矫治后2,3,4周的釉质脱矿指数高于矫治前(P < 0.05);TiO2-xNx薄膜托槽组矫治后1-4周的正畸菌斑指数、龈沟出血指数均低于普通金属托槽组(P < 0.05),矫治后2-4周的牙龈指数、釉质脱矿指数均低于普通金属托槽组(P < 0.05)。表明TiO2-xNx薄膜托槽具有较好的抗菌效果,可更好地控制和清除菌斑。

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 all 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 excellent antibacterial properties, which is better to control and removal dental plaques.
