OBJECTIVE: Compare the antimicrobial effectiveness of common antimicrobial paste immediately after pulp therapy and in different storage conditions.
STUDY DESIGN: 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.
RESULTS: The GP paste showed antimicrobial activity at all experimental times.
CONCLUSION: The pastes presented antimicrobial effectiveness at all experimental times.
