The past few decades have witnessed remarkable progress in the application of artificial intelligence (AI) and machine learning (ML) in medicine, notably in medical imaging. The application of ML to dental and oral imaging has also been developed, powered by the availability of clinical dental images. As ML models become more adaptive day by day, there is a huge scope for further enhancement of these tools and their application in dentistry.

ML, as a branch of AI, empowers computers to learn and make decisions from data without being explicitly programmed. It's like teaching a computer to recognize patterns or trends. Instead of providing rigid instructions, you feed the machine a lot of information, and it figures out how to solve problems or make predictions on its own. For instance, it can identify objects in photos, predict stock market trends, or recommend movies based on your preferences. Machine Learning is all about computers learning from data to assist us in solving complex problems and making smarter decisions.

ML, the ever-evolving domain of AI, has, in recent years, become synonymous with innovation across various industries. It is the digital guardian behind self-driving cars, the curator of personalized playlists, and the diagnostic powerhouse in healthcare. But in the realm of dentistry, its remarkable potential to revolutionize oral care has remained relatively uncharted territory.

Applications currently available in the dental industry:

  • V7: A computer vision platform that allows dentists to build and deploy AI solutions for dental imaging, such as dental decay and periodontal disease detection, oral cancer detection, endodontics, and orthodontic treatment planning.
  • Dentem: A cloud-based dental practice management software that uses ML to automate tasks such as appointment scheduling, billing, patient communication, and analytics.
  • Denti.AI: A dental image analysis software that uses ML to detect and diagnose dental caries, periodontal diseases, bone loss, and other oral conditions.
  • Pearl: A dental AI company that offers various products such as Smart Margin (a margin marking software for dental restorations), Smart Radiology (a radiograph interpretation software), and Smart Triage (a teledentistry software).
  • Overjet: A dental AI company that provides products such as Overjet Vision (a dental charting software), Overjet Clinical Review (a dental claims review software), and Overjet Research Platform (a dental research software). The accuracy of ML software depends on various factors, such as the quality and quantity of the data used to train and test the ML models, the choice and complexity of the ML algorithms, the performance metrics and evaluation methods, and the clinical relevance and applicability of the results.

Accuracy rates:

Some of these software have reported high accuracy rates for different tasks and domains in dentistry. For example:

  • V7 claims to achieve an accuracy of 99.7% for dental decay detection, 98.9% for periodontal disease detection, and 97.8% for oral cancer detection.
  • Dentem claims to reduce human errors by 80% and increase productivity by 30%.
  • Denti.AI claims to achieve an accuracy of 95.4% for dental caries detection, 94.2% for periodontal disease detection, and 92.6% for bone loss detection.
  • Pearl claims to achieve an accuracy of 97% for margin marking, 96% for radiograph interpretation, and 95% for tele dentistry.
  • Overjet claims to achieve an accuracy of 98% for dental charting, 97% for dental claims review, and 96% for dental research.

However, these accuracy rates may not reflect the true performance of these software in real-world settings, as they may be based on limited or biased data or use inappropriate or inconsistent metrics. Moreover, accuracy is not the only criterion to evaluate the usefulness of ML software, as other factors such as reliability, validity, interpretability, generalizability, usability, and cost-effectiveness should also be considered.

Therefore, it is important to critically appraise the evidence and claims of these softwares before adopting them in clinical practice. More rigorous and standardized research is needed to validate and compare these software and their ML models. Ethical and legal issues such as data privacy, consent, liability, and accountability should also be addressed.


Some of the limitations of ML software are:

  • They may not be able to handle complex or rare cases that require human expertise and judgment, such as interdisciplinary or ethical issues.
  • They may not be able to explain their reasoning or decisions, which can affect the trust and acceptance of the users and patients.
  • They may not be able to generalize to different settings or populations, such as different dental systems, cultures, or demographics.
  • They may not be able to cope with the dynamic and evolving nature of dentistry, such as new technologies, techniques, or standards.
  • They may pose ethical, legal, and social challenges, such as data privacy, consent, liability, and accountability.

The use of ML in dentistry is still in its early stages, but it has the potential to revolutionize the way that dental care is delivered. ML models can help dentists to make more accurate diagnoses, provide more personalized treatment plans, and improve patient outcomes.

Other applications:

ML is also being investigated for use in a variety of other areas of dentistry, such as:

  • Drug discovery and development: ML can be used to identify new drug targets and to design and develop new drugs for the treatment of dental diseases.
  • Predictive analytics: ML can be used to predict the risk of developing dental diseases, such as caries and periodontal disease. This information can be used to develop personalized prevention strategies.
  • Clinical decision support: ML can be used to develop clinical decision support systems that can help dentists to make more informed treatment decisions.
  • Quality improvement: ML can be used to monitor the quality of dental care and to identify areas where improvements can be made.


  • One of the key challenges in the development of ML models for dentistry is the need for large and high-quality datasets. Dental data is often difficult to collect and can be subject to a variety of biases. As a result, it is important to carefully consider the data collection process when developing ML models for dentistry.
  • Another challenge is the need to ensure that ML models are explainable and interpretable. Dentists need to understand how ML models make decisions to trust them. As a result, it is important to develop ML models that are transparent and can be easily explained to dentists.


The future of ML in dentistry is bright. ML has the potential to transform the way dental care is delivered and to improve the lives of patients worldwide. As ML technology continues to develop, we can expect to see even more innovative applications of ML in dentistry.
