The objective of this study is to examine caregiver reactions to the use of the hum by Colgate Smart Kids Toothbrush and associated app by children with autism spectrum disorder (ASD).

This is a single-center, pretest-posttest, non-randomized, clinical study involving interviews with caregivers prior to utilization of the research toothbrush and after 4 weeks of product use by the child. All participants enrolled will be children ages 5-12 years and their primary caregivers. Participants will be asked to utilize a Hum by Colgate Smart Kids Toothbrush (manual or battery-powered) for four weeks.

To assure that subjects are comfortable with the oral care regime proposed, toothbrushes will be distributed based on the subject's previous oral hygiene habits. Children who are currently using manual brushes will receive the Hum by Colgate Smart Manual Kids Toothbrush, likewise, children who are used to battery-powered toothbrushes will receive the Hum by Colgate Smart Kids battery-powered toothbrush.

All the participants will be offered the electric toothbrush and will have a chance to try it during the first visit.

All information may be stored or shared for future research purposes. All the information will be de-identified. All audio recordings will be transcribed and de-identified. De-identified means that all identifiers have been removed. The information could be stored and shared for future research in this de-identified fashion. The information may be shared with other researchers within Penn, or other research institutions, as well as pharmaceutical, device, or biotechnology companies. It would not be possible for future researchers to identify the subjects as we would not share any identifiable information about the subjects with future researchers. This can be done without again seeking their consent in the future, as permitted by law. The future use of the information only applies to the information collected on this study.
