Astudy on antibacterial effect of tray cleaner containing surface active agent.

Abstract

Bacteria that are adhered to alginate impression material remains in the impression material, and the treatment to disinfect should be done during removal of the impression and cleaning of the tray. Therefore, experimental tray cleaner (EX) containing the surface active agent, (Sodium alkyl di-aminoethyl glycine), which has antibacterial effect is produced.

The purpose of this study was to examine antibacterial effect of EX, solutions of each component of EX (1.00% EDTA-2Na, 0.50% EDTA-4Na, 1.26% Na₃PO₄, 0.25% Na₂CO₃, and 0.04% ADEG-Na), Super Tray Cleaner^® (SP, SHOFU), and Treclean^® (TC, GC) to Staphylococcus aureus (IFO 14462).The results are as follows:

1. The surface active agent, ADEG-Na, showed stronger antibacterial effect than any other component of EX.

2. The EX was stronger antibacterial effect than the EX without ADEG-Na.

3. The EX had stronger antibacterial effect than SP and TC. It suggested that the ADEG-Na played an important part for antibacterial effect in EX.
