Overview

• Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest.
• The research has huge potential for discovering individual food preferences, developing healthy food alternatives and early diagnosis of oral cancers in the future, experts say.
• The AI models were designed to gain a better understanding of individual features of the participant's papillae and to predict the age and gender of each volunteer.
• The AI tool could predict the type of papillae to within 85 per cent accuracy and map the position of filiform and fungiform papillae on the tongue's surface.
• Individuals could be identified with an accuracy of 48 per cent from a single papilla.
