AI Transforms Dental Care From Cavity Detection to Patient Self-Management
Comprehensive review reveals how artificial intelligence is revolutionizing dental caries management across clinical practice, education, and patient care.
Summary
This comprehensive review examines how artificial intelligence is transforming dental caries management beyond traditional 'drill and fill' approaches. AI applications span risk assessment, early detection from radiographic images, treatment planning, dental education through simulations, and patient self-care tools that track brushing patterns. The technology shows particular promise in analyzing multiple risk factors simultaneously to predict cavity development, with some systems achieving 81% accuracy in predicting future caries in children. AI-powered diagnostic tools demonstrate 68-99% accuracy in detecting cavities from various types of dental X-rays, potentially reducing subjective interpretation errors.
Detailed Summary
Dental caries affects over 3 billion people globally, making it one of the most prevalent chronic diseases despite being largely preventable. This comprehensive review explores how artificial intelligence is revolutionizing caries management through a patient-centered, risk-based approach that prioritizes prevention and early intervention over traditional restorative treatments.
The authors examined AI applications across four key areas: clinical risk assessment, diagnostic imaging, professional education, and patient self-care. For risk prediction, AI systems analyze multiple factors simultaneously - from demographics and oral hygiene habits to genetic markers and microbiome data. The MiC (Microbial Indicators of Caries) system achieved 81% accuracy in predicting future cavities in children by analyzing oral microbial shifts. These multi-factorial approaches outperform traditional risk assessment tools like CAMBRA and Cariogram.
In diagnostic imaging, deep learning algorithms, particularly convolutional neural networks (CNN), show remarkable performance in detecting caries from radiographs. Accuracy ranges from 68.7-94.59% on bitewing X-rays and 82-99% on periapical and panoramic images. Popular algorithms include ResNet, YOLOv5, U-Net, and custom models like CariesNet. However, performance varies significantly due to limited sample sizes and dataset heterogeneity.
For dental education, AI enables risk-free training through simulations and virtual case studies, allowing students to practice clinical skills without patient risk. In patient care, AI-powered tools track brushing patterns, provide real-time feedback, and improve oral hygiene compliance through personalized recommendations.
The technology's strength lies in processing vast amounts of data simultaneously - combining radiographic images, clinical history, genetic factors, and behavioral patterns to create comprehensive risk profiles. This holistic approach represents a significant advancement over single-factor assessment methods, potentially enabling truly personalized preventive care strategies.

Methodology
This is a comprehensive narrative review examining AI applications in dental caries management across multiple domains. The authors analyzed existing literature on AI algorithms including machine learning, deep learning, and neural networks applied to caries risk assessment, diagnostic imaging, education, and patient care. The review focused on performance metrics including sensitivity, specificity, accuracy, F1 scores, and intersection-over-union scores from various published studies with sample sizes ranging from 197 to 4,278 cases.
Study Limitations
The review notes significant limitations including small sample sizes and substantial dataset heterogeneity across studies, leading to variable AI performance. Most systems rely on supervised learning requiring extensive manual data annotation. Limited real-world validation and standardization of AI tools remain challenges. The authors emphasize need for larger, population-diverse cohorts with robust clinical annotations to accurately represent AI performance in clinical practice.
