Area of Science:

Artificial Intelligence in Dentistry
Periodontal Disease Diagnosis
Medical Imaging Analysis

Background:

Periodontitis significantly impacts oral and systemic health.
Traditional diagnosis via clinical probing is time-consuming, uncomfortable, and operator-dependent.
Novel methods are needed for efficient and accurate periodontal assessment.

Purpose of the Study:

To investigate the feasibility of using computer vision on radiographs to estimate periodontal stability.
To develop models for classifying teeth and patients based on periodontal health from radiographic data alone.

Main Methods:

Intraoral radiographs were used to train computer vision models.
A 3-way classification model categorized teeth as healthy, stable, or unstable.
A binary patient classifier determined overall stability based on tooth status.

Main Results:

The tooth classification model showed moderate performance (AUCs 0.56-0.71, F1 scores 0.45-0.57).
The patient classification model achieved an AUC of 0.68 and an F1 score of 0.74.
Saliency maps highlighted clinically relevant areas around teeth.

Conclusions:

Computer vision can estimate periodontal stability from radiographs, potentially reducing reliance on clinical probing.
Further model refinement is necessary, particularly for tooth-level classification accuracy.
Radiographic analysis using AI shows promise for improving periodontal disease management.
