Abstract

Objective: The present study aimed to compare the efficacy of two disinfectants against Gram-positive bacteria, particularly Streptococcus mutans,
for use as a disinfectant for dental retainers.
Methods: In total, 35 thermoplastic retainers in this study were categorized into three immersion groups: control group; mouthwash group, using
chlorhexidine 0.1%; and denture cleanser tablet group. The retainers were worn for 15 days, and Gram-positive bacteria were enumerated before and
after the retainers were immersed.
Results: We found a significant difference in bacterial numbers between the two disinfectant groups and the non-disinfectant or control group. Both
disinfectant groups had decreased numbers of Gram-positive bacteria.
Conclusions: Disinfectant use is effective in decreasing the load of Gram-positive bacteria on thermoplastic retainers.

Keywords: Disinfectant, Disinfection, Thermoplastic retainer, Gram-positive bacteria, Streptococcus mutans
