Science Buddies: "Ask an Expert"

My daughter wants to do this project to determine the effectiveness of caries indicator to show tooth decay. My dentist gave us teeth, some with visible decay and some without. I know how caries indicator works but can't figure out how to measure the effectiveness. Any suggestions on this?

Hi,

A science project on tooth decay would be an excellent project, and you are right to be concerned about measuring the results... Is your daughter planning to use the bright pink vegetable dye that dentists use or another method? Please describe the measurement technique that you are thinking about using. Ideally, your daughter will want to design a controlled experiment with measurable results.

Has your daughter found any background reference articles? What is the research question? Here is the guide for doing science projects from the Science Buddies website that contains step-by-step suggestions for each stage of a project.
