Aim: The aim of this research was to evaluate the efficiency of Steri® 350glass bead sterilizer, on the infection control of the active part of the orthodontic pliers. Methods: Nine orthodontic pliers were sterilized in the steam autoclave at 121ºC in 20 minutes and subsequently the active part of each plier was dipped in a culture for Bacillus stearothermophilus. Later, the active part of each plier was putted into the Steri® 350 in the following periods: 3, 5, 10, 15, 20, 30, and 40 seconds at 255ºC to evaluate the efficiency of this method in the infection control. Results and conclusions: This sterilization method has been effective to control the presence of Bacillus stearothermophilus on the active part of orthodontic pliers at 255ºC in 10 seconds.
