Summary
This study developed a deep learning method to identify 11 types of dental restorations. The AI accurately recognized metallic prostheses but showed moderate accuracy for tooth-colored restorations.
Area of Science:
- Dentistry
- Artificial Intelligence
- Computer Vision
Background:
- Dental restorations and prostheses are crucial for oral health.
- Accurate identification of these dental elements is important for diagnosis and treatment planning.
- Automated recognition systems can aid dental professionals.
Purpose of the Study:
- To develop and evaluate a deep learning (DL) model for recognizing 11 types of dental prostheses and restorations.
- To assess the performance of the DL model using metrics like mean average precision (mAP) and mean intersection over union (mIoU).
Main Methods:
- A dataset of 1904 oral photographic images was utilized.
- A DL model was developed using TensorFlow and Keras.
- The model was trained to recognize 11 distinct types of dental restorations.
Main Results:
- The DL system achieved a mean average precision (mAP) of 0.80 and a mean intersection over union (mIoU) of 0.76.
- High accuracy (over 80%) was observed for detecting metallic dental prostheses.
- Moderate accuracy (around 60%) was achieved for tooth-colored prostheses.
Conclusions:
- Deep learning models can effectively recognize metallic dental prostheses with high accuracy.
- Current DL models demonstrate moderate accuracy in identifying tooth-colored dental restorations.
- Further research may be needed to improve the recognition of tooth-colored dental restorations.
