Background:

Traditional tooth Computed Tomography (CT) image segmentation methods suffer from low accuracy and inefficiency.
Complex dental structures in CT scans pose challenges for precise segmentation.

Purpose of the Study:

To develop an improved segmentation method for tooth CT images using deep learning.
To enhance segmentation accuracy, reduce information loss, and improve positioning in tooth CT image analysis.

Main Methods:

A U-Net network was adapted for tooth image segmentation, incorporating supplementary feature maps during downsampling to minimize information loss.
An attention module was integrated into the U-Net architecture, utilizing subregion average pooling to focus on critical spatial features and improve segmentation accuracy.
The enhanced U-Net model was trained and validated using a dataset from West China Hospital.

Main Results:

The proposed method demonstrated superior segmentation performance and efficiency compared to existing algorithms.
The segmentation resulted in clearer tooth contours, facilitating better diagnostic assistance for clinicians.
The integration of attention mechanisms and modified pooling strategies effectively addressed segmentation inaccuracies.

Conclusions:

The improved U-Net model with an attention module offers a robust solution for accurate and efficient tooth CT image segmentation.
This technique provides clearer dental imagery, significantly supporting clinical diagnosis and treatment planning.
The study highlights the potential of deep learning advancements in dental imaging analysis.
