Tooth Anatomy

1.1K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

    Area of Science:

    • Artificial Intelligence in Dentistry
    • Medical Image Analysis
    • Dental Diagnostics

    Background:

    • Cracked teeth pose a diagnostic challenge due to subtle and irregular features.
    • Early detection is vital to prevent further dental damage and complications.

    Purpose of the Study:

    • To develop an automated system for accurate cracked tooth detection and segmentation.
    • To improve upon existing methods for identifying subtle dental fractures.

    Main Methods:

    • An improved Mask R-CNN instance segmentation network was utilized.
    • ResNeXt-50(32×4d) backbone and a Crack Feature Enhancement Module (CFEM) were incorporated.
    • A redesigned mask head with encoder-decoder structure and dynamic snake convolutions was implemented.

    Main Results:

    • The proposed method demonstrated superior performance compared to state-of-the-art techniques.
    • Experiments on real intraoral images confirmed the model's effectiveness in detecting tooth cracks.
    • The system achieved more accurate and earlier detection of cracked teeth.

    Conclusions:

    • The developed AI model offers a significant advancement in diagnosing cracked teeth.
    • This technology facilitates timely interventions, reduces invasive treatments, and preserves tooth structure.
    • The availability of code and datasets promotes further research and application in dental diagnostics.
