Ever wonder how successful it is at killing harmful bacteria in a person's mouth? Several types of bacteria are commonly found in the mouth, but high school student, Israt Hossain, decided to test the effectiveness of several products - fluoride rinses \u003cem\u003eand\u003c\/em\u003e antiseptic mouthwashes - on inhibiting the growth of \u003cem\u003eStaphylococcus epidermidis\u003c\/em\u003e. \u003c\/p\u003e\u003cp\u003e\u003cspan id=\"more\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eTo complete this project, he chose to test six different mouthwashes, along with water as a control. The only other items he needed, besides the various products, were Petri dishes, agar, sterile paper disks, and a place to incubate the samples.

There are a bunch of detergents out there so, to narrow down his testing field, Dao began his project with a survey of local laundry mats to determine which brands were the most popular. His results showed that Tide, Gain, and All were the popular choices. \u003c\/p\u003e\n\u003cp\u003eTo complete the project, Dao needed the following materials - a sterile Petri dish, agar, sterile filter paper, detergent samples, and a place to incubate the samples. After 24 hours, he checked the results and measured the zones of inhibition.
