Summary

This study compares two types of toothbrushes to see which one stays cleaner after use. Researchers want to know if toothbrushes with charcoal-infused bristles have fewer bacteria than standard toothbrushes with nylon bristles.

Participants in this study are adults and children who do not have gum disease or other major health issues. Everyone in the study will be assigned one of two types of toothbrushes:

* An eco-friendly toothbrush with charcoal bristles.
* A standard toothbrush with nylon bristles. Participants will use their assigned toothbrush at home for two specific time periods (one day and one week). They will follow simple instructions on how to brush and store the toothbrush. After each time period, they will return the toothbrush to the researchers.

The research team will test the bristles in a lab to count the bacteria. They will also measure how well the charcoal bristles stop bacteria from growing compared to the nylon bristles. This will help determine if charcoal toothbrushes are a more sanitary and eco-friendly option for daily oral care.
