The purpose:
was to determine the effectiveness of two disinfecting agents in impressions with irreversible hydrocolloids.
Methods and Materials:
10 students of Autonomous University of Tamaulipas-Dentristy Faculty were selected, after the nature of the study was explained and signed the consent form, it was proceeded to obtain dental impressions with irreversible hydrocolloids (Phase Plus^R, Zhermak) in the upper arch (n=10). The dental impressions were sectioned and placed in Petri dishes with Trypticasein Soy Broth as culture media. Afterwards, a sample was taken to isolate identify and make bacterial stock and then was divided into three groups: Group A: 0.5ml of bacterial stock + 0.5ml of Saline Solution (PiSA^R) Group B: 0.5ml of bacterial stock + 0.5ml Etanol + 2-propanol (Z 7 Spray^R Zhermak) Group C: 0.5ml of bacterial stock + 0.5ml of Morinda Citrifolia, incubation time was two minutes and was inoculated in culture media, and counted after 24 hrs of incubation.
A significant relevance of the antimicrobial factor agent (p=<0.0001) was identified. The control group presented the highest values in relation with the bacterial count (media=4.69 +_ 0.65 Log10UFCxml) followed by the Morinda citrifolia group (media=2.25+_ 1.76 Log10UFCxml) and the Etanol + 2-propanol group reported a minor growth (media=1.03+_ 1.93Log10UFCxml). The bacteria that was isolated more times was the Staphylococcus aureus ( 30%).
The Morinda citrifolia and the Di-ethanol decreased the bacterial growth in irreversible hydrocolloids.
