Tooth-to-white spot lesion YOLO: a novel model for white spot lesion detection
This paper introduces TW-YOLO, a novel deep learning model designed for highly accurate detection of white spot lesions (WSLs) in intra-oral photographs. By employing a unique two-step detection strategy and preserving original image resolution for critical analysis, the model significantly outperforms traditional YOLOv5 approaches, offering a transformative tool for early intervention in orthodontic patients.
Executive Impact: Revolutionizing Early Orthodontic Intervention
The TW-YOLO model represents a significant leap forward in dental diagnostics, offering enterprises a powerful AI tool to enhance patient care, streamline orthodontic workflows, and mitigate the long-term costs associated with untreated WSLs. Its superior accuracy and focused detection capabilities translate directly into improved clinical outcomes and operational efficiency.

Explainability Analysis: Unveiling Model Focus
Our Score-CAM analysis revealed key insights into TW-YOLO's superior performance. Unlike YOLOv5l, which often diverted attention to irrelevant areas like lips and oral mucosa, TW-YOLO consistently concentrated on the peripheral region of the tooth labial surface, precisely where WSLs are most prevalent. This focused attention on crucial anatomical areas, combined with its ability to retain detail at original resolution through tiled processing, significantly contributed to its improved detection accuracy and reduced false negatives.
