Area of Science:

Dentistry
Medical Imaging
Artificial Intelligence

Background:

Accurate tooth segmentation and numbering are crucial for automated dental diagnosis and treatment planning.
Existing methods may lack the precision required for complex clinical applications.

Purpose of the Study:

To develop and evaluate a multitask learning architecture for precise tooth segmentation and numbering in panoramic dental X-ray images.
To improve the efficiency and accuracy of automated dental diagnostic workflows.

Main Methods:

A novel multitask learning framework integrating a graph convolution network, a detection subnetwork (DSN), and a region segmentation subnetwork (RSSN).
Feature fusion between DSN and RSSN to enhance boundary regression accuracy.
Utilized panoramic X-ray images for training and validation.

Main Results:

The proposed framework achieved high performance across multiple evaluation metrics.
Top F1 score of 0.9849, Dice metric score of 0.9629, and mean Average Precision (mAP) of 0.9810 (IOU = 0.5).
Demonstrated significant improvements in tooth segmentation and numbering accuracy.

Conclusions:

The developed multitask learning framework offers a robust solution for automated tooth segmentation and numbering.
This technology has the potential to substantially enhance clinical efficiency for dentists.
The framework shows promise for advancing automated dental diagnosis and treatment planning.
