Bacterial Contamination of Endodontic Materials before and after Clinical Storage.


PMID 28951029

Abstract

The aim of this study was to evaluate the bacterial contamination in endodontic consumables (gutta-percha points, rubber dams, paper mixing pads, caulking agents, and endodontic instrument sponges [EISs]) before and after clinical use and storage. Materials were randomly sampled in triplicates at 3 time points (t All tested materials showed a varied number of contaminated samples at the 3 time points (except EIS at t The majority of the tested materials harbored bacteria in their samples before and after clinical storage. Nosocomial infection derived from commonly used consumables could have an impact on the outcome of endodontic treatment.
