Semi-supervised classification of dental conditions in panoramic radiographs using large language model and instance segmentation: A real-world dataset evaluation

Bernardo Silva, Jefferson Fontinele, Carolina Letícia Zilli Vieira, João Manuel R. S. Tavares, Patricia Ramos Cury, Luciano Oliveira·June 25, 2024

Summary

This study proposes a semi-supervised learning method for classifying thirteen dental conditions in panoramic radiographs, leveraging large language models and a combination of masked autoencoders and Vision Transformers. The approach outperforms baselines in terms of Matthews correlation coefficient, addressing the limited labeled data issue. The authors validate their method using two extensive datasets, showing results competitive with human practitioners. The study highlights the potential of combining textual reports, image analysis, and unlabeled data to enhance dental diagnosis, with a focus on context-rich image crops and inter-rater agreement for improved performance. Future research should continue to explore data augmentation, alternative learning methods, and optimal crop sizes for more accurate and efficient dental image analysis.
