    I wished the tested against electric toothbrush:

    Moreover, while the present study com-
    pared the self-charged toothbrushes with conventional nylon tooth-
    brushes, further comparisons with commercially available electric,
    sonic, or antimicrobial-coated alternatives are essential for fully es-
    tablishing the translational advantage of the piezoelectric approach
    over existing oral care technologies
