title: Effectiveness of implant surface decontamination using a high-pressure sodium bicarbonate protocol:  an in vitro study.
abstract: OBJECTIVE
  To evaluate the effectiveness of a high-pressure sodium bicarbonate spray protocol to decontaminate implant surfaces intentionally inoculated with bacteria.
  
  
  METHODS
  Twenty commercially pure titanium implants, 10 with machined surfaces and 10 with rough surfaces, were inoculated with Streptococcus sanguis and then submitted to a decontamination protocol using a high-pressure sodium bicarbonate spray device for 1 minute under aseptic conditions.
  
  
  RESULTS
  After the application of the decontamination protocol, all bacterial cells were removed from the tested implants, regardless of surface roughness.
  
  
  CONCLUSIONS
  The results suggest that regardless of the implant surface roughness, the protocol using high-pressure sodium bicarbonate spray for 1 minute, under aseptic conditions, was effective in removing all the viable bacterial cells.
