Evaluation of the readability, quality, and accuracy of AI chatbot responses to questions about deleterious oral habits.

Résumé

BACKGROUND: Artificial intelligence (AI)-based chatbots are increasingly used by parents as convenient and fast-access sources of information on health-related topics.

These were classified into seven categories based on specific types of deleterious oral habits, including thumb sucking, bruxism, pacifier use, bruxism, tongue thrusting, lip sucking, nail biting, and mouth breathing. Responses from each AI chatbot were evaluated using multiple evaluation tools including Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), the modified DISCERN tool (mDISCERN), Global Quality Score (GQS), and misinformation scoring system.
