WizWe, Naha City, and NTT West announced results for their 'Dental Health Habituation Support Project' in Naha. Using psychological accompaniment via LINE, approx. 70% of participants established a habit of brushing their children's teeth 5+ times a week. The child dental visit rate also rose from 18% to 45%. The support proved especially effective for parents of 1- and 3-year-olds, periods considered difficult for child-rearing.

WizWe Co., Ltd. (CEO: Kohei Moritani), Naha City (Mayor: Satoru Chinen), and NTT West Corporation (President: Ryota Kitamura) have reported the results of their joint 'Dental Health Habituation Support Project - Polishing more than just teeth. Polishing parent-child trust and future health too.' This demonstration addressed Okinawa's regional issue of high childhood cavity rates by introducing a behavioral science-based habit-formation model to promote daily tooth-brushing habits.

Targeting parents of preschoolers in Naha City, the project provided 'Shiagemigaki Support NAHA' via LINE. It combined image-based messages and two-way communication with dedicated supporters to provide 'psychological accompaniment' that empathized with parents.

Key Demonstration Results 1. Habituation of Tooth Brushing: The average recording rate for brushing 5+ times a week reached 67.4%, exceeding the 60% goal. 66.7% of participants reached their KPIs, indicating approx. 70% habituated. Even the previously non-habituated group saw their recording rate improve to 62.5%. 2. Change in Dental Visit Rates: The dental visit rate for children increased from 18% before the project to 45% upon completion (73% including future intentions). This prompted action in previously non-visiting families. 3. Shift in Health Awareness: 91.9% of parents reported an improvement in their health awareness, showing a ripple effect on conscious change.

Key Factor for Success: Psychological Accompaniment Support The results suggest that psychological support—empathizing with parents' anxieties, affirming what they are currently doing, and offering low-hurdle suggestions—worked effectively beyond simple information sharing. This was particularly crucial during 'difficult periods' such as around age 1 (unstable daily rhythms) and age 3 (resistance due to developing self-will).

Moving forward, the partners aim to expand the Naha model across Okinawa Prefecture and eventually nationwide as a sustainable support model combining technology and psychological accompaniment.
