About the study
The purpose of this study is to test photobiomodulation (PBM) with a non-invasive light device for reducing discomfort during dental treatments in children. We plan to conduct a series of three clinical studies in 200 school-aged children requiring routine dental treatment. The first study aims to test if PBM works for tooth and soft tissue by assessing response to cold testing and probing of gums. The second study aims to test if use of PBM on soft tissues before injection reduces discomfort. The third study aims to test if PBM can be used to do simple dental fillings in baby teeth without numbing injection.
