Contamination analysis of absorbent paper points and the influence in endodontic treatment. Rev. Assoc. Paul. Cir. Dent. [online]. 2014, vol.68, n.4, pp. 331-335. ISSN 0004-5276.

The purpose of this study was evaluate microbiologically absorbent paper points present in conventional sealed packages or "CELL PACK" type, and paper points that were already being used in clinical practice. So check handling and environment in which they are exposed, contributes to contamination and if the microorganisms found influence in the outcome of endodontic treatment. Were used 4 brands of paper points (EndoPoints, Tanary, Precise and Meta) from sealed packages, called sterilized by the manufacturer in conventional packages and "CELL PACK" type. And 90 absorbent paper points (Tanary, Roeko, Endo Points, Conne Teck), collected from 30 private practices and already being used in clinical practice. All samples were transferred to tubes containing BHI broth and incubated at 37 °C under an atmosphere of CO2. In the presence of contamination, samples were plated on BHI agar and bacterial identification performed through specific tests. None of paper cones from the sealed packs showed microbial growth. However, there was contamination of cones which were in clinical use. The authors conclude that absorbent paper points present in sealed packages, initially are sterile. However, the "CELL PACK" type are more effective and safer, because they have a sufficient number of cones in individual cells. Furthermore, paper points of conventional packs, after opening, may present contamination, contributing to the failure of endodontic treatment
