Description
Summary:Objective To compare the in vitro decontamination efficacy of two electrolytic cleaning methods to diode laser, plasma, and air-abrasive devices. Material and methods Sixty sandblasted large-grit acid-etched (SLA) implants were incubated with 2 ml of human saliva and Tryptic Soy Broth solution under continuous shaking for 14 days. Implants were then randomly assigned to one untreated control group ( n  = 10) and 5 different decontamination modalities: air-abrasive powder ( n  = 10), diode laser ( n  = 10), plasma cleaning ( n  = 10), and two electrolytic test protocols using either potassium iodide (KI) ( n  = 10) or sodium formate (CHNaO 2 ) ( n  = 10) solution. Implants were stained for dead and alive bacteria in two standardized measurement areas, observed at fluorescent microscope, and analyzed for color intensity. Results All disinfecting treatment modalities significantly reduced the stained area compared to the untreated control group for both measurement areas ( p
