现代根管治疗术中广泛地应用牙胶尖来充填根 管,而牙胶尖却不能通过常规的高温高压方式进行消毒。以往的文献所报道的在进行椅旁快速消毒牙胶尖的各种方法中,以次氯酸盐和戊二醛最为有效。但前者存在次氯酸盐不稳定的缺点。 本文对5种市售2％戊二醛溶液用于牙科椅旁快速消毒牙胶尖的效果进行评价。 材料和方法 选取Dentsply #80和Diadent #80两种品牌牙胶尖,消毒或干燥。部分备用,部分用枯草杆菌(ATCC6633)孢子悬浊液浸泡30min进行人工污染。选取5种市售戊二醛溶液,并使终浓度均为2％。每
Modern root canal therapy widely used gingival canals to fill the root canal, while the gutta percha point is not through the conventional high temperature and pressure disinfection. Hypochlorite and glutaraldehyde are most effective in various methods reported in prior literature for rapid disinfection of gutta percha near chairs. However, the former has the disadvantage of hypochlorite instability. In this paper, 5 kinds of commercially available 2% glutaraldehyde solution for dental chairs next to the rapid disinfection gutta-percha evaluation. Materials and methods Dentsply # 80 and Diadent # 80 two brands of gutta percha, disinfection or drying. Part of spare, some with Bacillus subtilis (ATCC6633) spore suspension immersion 30min artificial contamination. Five commercially available glutaraldehyde solutions were selected and the final concentration was 2%. each
