    Area of Science:

    • Artificial Intelligence in Healthcare
    • Medical Imaging Analysis
    • Dental Diagnostics

    Background:

    • Dental radiographs are crucial for diagnosis, with AI, particularly Convolutional Neural Networks, showing promise in analysis.
    • Existing datasets lack comprehensive expert annotations and multimodal data, hindering AI development in dentistry.

    Purpose of the Study:

    • Introduce the Tufts Dental Database, a novel multimodal dataset of 1000 panoramic dental radiographs.
    • Facilitate the integration of human expertise into AI for improved dental abnormality detection.
    • Establish benchmark performance for AI systems in dental radiograph analysis.

    Main Methods:

    • Curated a dataset of 1000 panoramic dental radiographs with expert labels for abnormalities and teeth.
    • Classified images based on anatomical location, peripheral characteristics, radiodensity, surrounding effects, and abnormality category.
