Implications
The paper presents a hybrid Deep Learning model combining CNNs for feature extraction and LSTMs for sequence modeling to predict tooth extraction decisions from intraoral and extraoral images. It addresses class imbalance using oversampling techniques.
The study utilized a dataset of 1720 images from 215 patients. Various CNN architectures (VGG16, VGG19, ResNet50, ResNet101, EfficientNetB0) were evaluated. Key techniques included image preprocessing, data augmentation, and different class balancing strategies (subsampling, oversampling).
The VGG19 model with minority class oversampling achieved the best performance with an F1-Score of 89.52% and an AUC of 95.21%, significantly improving sensitivity (81.03%) compared to baseline. Intraoral images were found to provide more diagnostic value than extraoral images.
This Deep Learning solution has significant potential as an orthodontic clinical decision support system, reducing inter-clinician variability and aiding in more objective treatment planning. It provides a robust framework for predicting tooth extraction needs even with limited datasets.

Impact of Image Data Type
Models performed better in classifying intraoral images (AUC values higher than extraoral images), suggesting these views provide more diagnostic information for tooth extraction decisions. The integration of both types further enhances performance. This insight is crucial for optimizing data collection in future AI-powered diagnostic tools.
The VGG19 model, when using intraoral images, achieved an F1-Score of 85.15% and an AUC of 93.04%, showcasing the diagnostic value of detailed intraoral views.
