Impact of Oral Health Chatbot With and Without Toothbrushing Training on Childhood Caries.

Objectives: Standalone oral health chatbots targeting young children's oral health are rare. The aim of this research was to compare the effectiveness of a standalone chatbot and a combination chatbot with in-person toothbrushing training for caregivers in improving young children's oral health.

Methods: A randomised, parallel, 2-group pretest-posttest design was employed with 320 caregiver-child pairs (aged 6-42 months).
