Summary

Researchers are testing whether artificial intelligence can identify dental anxiety in children by analyzing their speech. Children aged 8 to 12 at a pediatric dentistry clinic answer short questions before treatment, and their voice recordings are examined for acoustic and language patterns. The study compares these AI results with three standard anxiety questionnaires to see how well the technology distinguishes between children with lower and higher fear. No treatment is given or changed; the goal is to see if a quick speech test could serve as a reliable anxiety screening tool.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Multimodal speech-based dental anxiety assessment using artificial intelligence
What this could lead to
If it works, this could give dentists a quick, objective way to spot anxious children before treatment, helping them tailor care and reduce fear.
What could go wrong
The study is observational and early, so the AI may not be accurate enough for real-world use. Speech patterns vary widely, and results may not apply beyond this specific group.

Who is studied

he study population consisted of children aged 8-12 years who attended the Department of Pediatric Dentistry at Marmara University Faculty of Dentistry for routine dental care between September 2025 and February 2026. Eligible children completed a standardized speech recording and three dental anxiety assessments during a single visit before dental treatment. Children with both lower and higher levels of dental anxiety were included. Participation did not alter or delay the dental care planned for any child.
