Study design: single-center, pretest–posttest, non-randomized clinical study involving interviews with caregivers prior to utilization of a Smart E-Toothbrush after 4 weeks of toothbrushing experience by the child. Questionnaires for caregivers were administered at three timepoints throughout the study, and daily text message questions about toothbrushing frequency were sent to caregivers. Interviews focused on experiences such as thoughts, feelings, intentions, observations, and behaviors upon introduction of the new device.
