effect rather than bacterial sterilization.
The part where the bristles are attached to the head can be full of bacteria such as Streptococcus, which causes oral cavity.
Antibacterial test for Silver Nano toothbrushes was successfully verified.
In the first experiment, a Silver Nano toothbrush was submerged on a culture medium of Streptococcus. The results were positive as bactericidal and antifungal inhibition were not shown.
In the second experiment, both Nano toothbrush and ordinary toothbrush were rinsed after brushing. As a result of culturing, the bacterial proliferation was significantly lower in that of the Nano toothbrush than in the ordinary toothbrush.
The Silver Nano toothbrush proved its capability in restraining the remaining bacteria.
In conclusion, the Silver Nano toothbrush contains a harmless residual bacterial inhibitory effect rather than bacterial sterilization.
Frequently asked questions
Where can bacteria accumulate on a toothbrush?
Bacteria such as Streptococcus can accumulate around the areas where the bristles are attached to the toothbrush head. These areas were highlighted as potential sites of bacterial contamination.
What experiments were conducted on Silver Nano toothbrushes?
Two experiments were conducted. The first involved placing a Silver Nano toothbrush in a Streptococcus culture medium, while the second compared bacterial growth on Silver Nano and ordinary toothbrushes after rinsing.
How did the Silver Nano toothbrush compare with an ordinary toothbrush?
The Silver Nano toothbrush showed significantly lower bacterial proliferation than the ordinary toothbrush after rinsing. This result demonstrated its ability to inhibit residual bacterial growth.
Does Silver Nano technology sterilize toothbrushes?
The experiments did not demonstrate a clear sterilizing effect. Instead, the findings indicated that Silver Nano technology helps inhibit the growth of residual bacteria.
What was the main conclusion of the antibacterial tests?
The Silver Nano toothbrush demonstrated an inhibitory effect on residual bacterial growth. The findings emphasized bacterial growth inhibition rather than bacterial sterilization.
