感染根管细菌的培养检测及药敏试验

The Bacteria Detection and Drug Sensitivity Test from Infected Root Canals

目的 为临床应用敏感药物治疗感染根管提供细菌学依据。方法 对 5 6例感染根管进行细菌培养 ,并用琼脂稀释法 ,对细菌进行药敏试验。结果 感染根管的细菌检出率、阳性率均很高 ,厌氧菌、需氧菌对各种抗菌药物敏感。结论 细菌与感染根管关系密切 ,临床应选择敏感性药物进行治疗。

Objective To provide bacteriological basis for curing infected root canals with sensitive drugs.Methods We have made bacterial cultivation for 56 cases with infected root canals and drug sensitive test with agar dilution.Results The rates of bacteria detection and positive rates from infected root canals were high. Anaerobia and aerobia were sensitive to different kinds of antibiotics. Conclusion Bacteria have close relation to infected root canals. Sensitive drugs should be selected in clinical treatment. [
