Automatic segmentation of teeth is crucial for diagnosing tooth structures, damages, and proposing the best dental treatments. Panoramic radiographs use ionizing radiation with a limited dose to capture a large area of the maxilla and mandible in a single projection.
Artificial intelligence enabled panoramic radiographs improve dental diagnostics and identify precise dental anamoly suggests a new study published in the Journal of Dentistry.
This research focuses on performing teeth segmentation with panoramic radiograph images using a denoised encoder-based residual U-Net model, which enhances segmentation techniques and has the capacity to adapt to predictions with different and new data in the dataset, making the proposed model more robust and assisting in the accurate identification of damages in individual teeth.
The effective segmentation starts with pre-processing the Tufts dataset to resize images to avoid computational complexities. Subsequently, the prediction of the defect in teeth is performed with the denoised encoder block in the residual U-Net model, in which a modified identity block is provided in the encoder section for finer segmentation on specific regions in images, and features are identified optimally. The denoised block aids in handling noisy ground truth images effectively.
Results
Proposed module achieved greater values of mean dice and mean IoU with 98.90075 and 98.74147. Proposed AI enabled model permitted a precise approach to segment the teeth on Tuffs dental dataset in spite of the existence of densed dental filling and the kind of tooth.
The proposed model is pivotal for improved dental diagnostics, offering precise identification of dental anomalies. This could revolutionize clinical dental settings by facilitating more accurate treatments and safer examination processes with lower radiation exposure, thus enhancing overall patient care.
