Energy output and in vitro biologic effects of an ionic toothbrush.

Unlabelled: The Soladey™ toothbrush has a moisture-permeable titanium dioxide (TiO2) resin core in the replacement brush end of a handle activated by light conversion power cells. Purported to have an antibacterial effect and remove more plaque than an ordinary toothbrush, this study was undertaken to establish output measurements of the dry and wet TiO₂ core of the toothbrush during typical illumination of the handle, then quantify lipid peroxidation in three distinct lipid-containing solutions, and bactericidal effects in a live bacterial suspension grown from suctioned oral secretions.

Methods: Within a range of illumination of the power cells in the handle, corresponding flow of electrons emitted from dry and wetted TiO2 cores was measured.
