通常认为局限性龈炎和菌斑在局部沉积有关。第一磨牙带环紧靠牙龈,患者清洗其周围牙龈困难,在临床上不能区别细菌性龈炎抑或为矫治器附件的腐蚀产物对局部组织刺激引起的发炎。作者认为矫治器附件的腐蚀产物对菌斑的抗菌作用比对牙龈粘膜的细胞毒性作用大,因此可以预防局限性龈炎。本文目的是评价在矫治器中不同金属附件的细胞毒素作用和抗菌作 It is generally accepted that localized gingivitis is associated with localized plaque deposition. The first molar band is in close contact with the gums and the patient has difficulty in cleaning the gingiva around them, clinically indistinguishable from bacterial gingivitis or inflammation of the tissue caused by local tissue irritation of the appliance accessories. The authors concluded that the corrosive products of the appliance attachment have a greater antibacterial effect on the plaque than the cytotoxic effect on the gingival mucosa and thus prevent localized gingivitis. The purpose of this paper is to evaluate the cytotoxic and antibacterial activities of different metal attachments in appliances
