目的:探讨不同的药物在铸造桩冠修复过程中根管再感染防治中的疗效。方法:将255颗牙齿进行根管取模后放置3种不同药物,A组使用樟脑酚组,B组使用氢氧化钙,C组使用抗生素。封药后观察不同药物对防止铸造桩冠修复过程根管再感染的临床效果。结果:三组的总有效率分别为89.4%、88.2%和100%,放置抗生素混合制剂,与其他两组比较,疼痛发生率明显降低,差异有显著性(P<0.05)。结论:根管内放置抗生素混合制剂,可以抑制根尖炎症,有效的防止铸造桩冠修复过程中的根管再感染。
Objective: To investigate the efficacy of different drugs in the prevention and treatment of root canal reinfection during the process of casting crown restoration. Methods: Three different drugs were placed in 255 teeth after root canal injection. A group used camphor phenol group, B group used calcium hydroxide and C group used antibiotic. Sealing drugs observed after different drugs to prevent the casting crown restoration process of root canal re-infection clinical effect. Results: The total effective rates of the three groups were 89.4%, 88.2% and 100%, respectively. Compared with the other two groups, the incidence of pain was significantly lower (P <0.05). Conclusion: The antibiotic mixture placed in the root canal can inhibit root apical inflammation and effectively prevent root canal re-infection during the process of casting crown restoration.
