My senior project is about the bacterial contamination of used toothbrushes aims to evaluate and identify the bacterial contamination on daily used toothbrushes. I distributed 50 toothbrushes among students living in dorms. They signed a consent form, and I asked them a questionnaire. By the 1st of March, I collected, analyzed and figured out the types of bacteria found on the distributed toothbrushes. Then I connected my results with the questionnaire they answered.
