AI systems promising for diagnosis of dental caries on intraoral radiographs suggests a study published in the Journal of Dentistry.

UNMUTE
This study aimed to assess the reliability of an AI-based system that assists the healthcare processes in the diagnosis of caries on intraoral radiographs. The proximal surfaces of the 323 selected teeth on the intraoral radiographs were evaluated by two independent observers using an AI-based (Diagnocat) system. The presence or absence of carious lesions was recorded during Phase 1. After 4 months, the AI-aided human observers evaluated the same radiographs (Phase 2), and the advanced convolutional neural network (CNN) reassessed the radiographic data (Phase 3). Subsequently, data reflecting human disagreements were excluded (Phase 4).

For each phase, the Cohen and Fleiss kappa values, as well as the sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy of Diagnocat were calculated. Results: During the four phases, the range of Cohen kappa values between the human observers and Diagnocat were κ=0.66–1, κ=0.58–0.7, and κ=0.49–0.7. The Fleiss kappa values were κ=0.57–0.8. The sensitivity, specificity and diagnostic accuracy values ranged between 0.51–0.76, 0.88–0.97 and 0.76–0.86, respectively. The Diagnocat CNN supports the evaluation of intraoral radiographs for caries diagnosis, as determined by consensus between human and AI system observers. The study may aid in the understanding of deep learning-based systems developed for dental imaging modalities for dentists and contribute to expanding the body of results in the field of AI-supported dental radiology..
