Compare the antimicrobial effectiveness of common antimicrobial paste immediately after pulp therapy and in different storage conditions.
Staphylococcus aureus, Staphylococcus epidermis, Streptococcus mutans, Streptococcus oralis, Enterococcus faecalis; Escherichia coli and Bacillus subtilis sample were used. The storage conditions utilized were: at room temperature--the paste was subjected to a natural aging process at room temperature for a 24-hour and 7, 14, 28, 60 and 90 day periods (GPRT). Refrigerator storage--the paste was placed to a natural aging process in a refrigerator at 4 degrees C for a 24 hour and 7.14, 28, 60 and 90 day periods (GPR). To perform the immediate effect analysis (GPi or zero time), of each mixture either at room or refrigerator temperature, the preparation procedure was similar, although GPR, iodoform, Rifocort and camphorated paramonochlorophenol were stored in the refrigerator and then taken out, dosed and manipulated, and had their immediate effect tested after a 1-week period at storage of 4 degrees C average temperature. The testing methodology was Dilution in Solid Medium-Agar. The Wilcoxon Test and Friedman variance analyses were used.
The GP paste showed antimicrobial activity at all experimental times.
The pastes presented antimicrobial effectiveness at all experimental times.
比较牙髓治疗后即刻及在不同储存条件下普通抗菌糊剂的抗菌效果。
使用金黄色葡萄球菌、表皮葡萄球菌、变形链球菌、口腔链球菌、粪肠球菌、大肠杆菌和枯草芽孢杆菌样本。所采用的储存条件为:室温——将糊剂在室温下进行自然老化处理,分别处理24小时以及7、14、28、60和90天(GPRT)。冰箱储存——将糊剂置于4℃冰箱中进行自然老化处理,分别处理24小时以及7、14、28、60和90天(GPR)。为了对每种混合物在室温或冰箱温度下进行即刻效果分析(GPi或零时间),制备程序相似,不过GPR、碘仿、利福平糊剂和樟脑对氯苯酚在冰箱中储存,然后取出、计量并操作,在平均温度4℃储存1周后测试其即刻效果。测试方法为固体培养基琼脂稀释法。采用威尔科克森检验和弗里德曼方差分析。
GP糊剂在所有实验时间均显示出抗菌活性。
