Avaliação microbiana da recontaminação de artigos odontológicos estéreis segundo o manuseio das embalagens

The handling of sterilized materials is one of the variables that may contribute to recontamination of the dental material during storage. This study aimed to evaluate the presence of recontamination of sterile dental materials from the handling of the envelopes stored for seven days in storage areas of the Central Supply and Sterilization. We used 72 samples as glass rods, divided into three groups: control group (12 sterilized glass rods without the liner), Group A (30 glass rods wrapped in packaging autoselante stored sealed in a cupboard where it was not allowed to handle the samples) and Group B (30 glass rods autoselante involved in packing, stored in a closet where he was allowed the handling of samples). All samples were submitted to microbiological analysis. We conducted descriptive and comparative analysis of results. Group B showed a higher growth of creamy colonies when compared to group A. Thus, we conclude that manipulation is an important variable in the re-contamination of materials by bacteria, due to the hand being the major route of transmission of these microorganisms.
