AI for early detection of gum inflammation


The University of Hong Kong’s Faculty of Dentistry, in collaboration with several international institutions, has made a significant breakthrough in the realm of dental health. They have successfully employed artificial intelligence (AI) to detect gum inflammation, or gingivitis, using intraoral photographs.

The AI Advantage:

Published in the International Dental Journal, the study reveals that AI algorithms can scrutinize intraoral photographs to identify signs of gum inflammation, such as redness, swelling, and bleeding, with an accuracy rate exceeding 90%. This precision rivals that of a dentist’s visual examination. Such advancements in technology can transform the way gum health is monitored, ushering in an era of more tailored dental care.

Collaborative Effort:

The research involved experts from the HKU Faculty of Dentistry, the Department of Computer Science at Hong Kong Chu Hai College, the School of Information Engineering at Guangdong University of Technology, and the Faculty of Dentistry at The National University of Malaysia. The team utilized a dataset comprising over 567 images of gums, showcasing varying inflammation levels, marking one of the pioneering efforts in leveraging AI for gum inflammation detection.

Significance of the Study:

Dr Walter Yu-Hang Lam, the study’s lead researcher from HKU, highlighted the potential of AI in the early detection and management of gum diseases. He noted that many patients often neglect regular dental check-ups, only seeking professional help when they experience severe pain, often at advanced stages of dental diseases. With AI, early detection becomes feasible, allowing timely interventions and promoting better health outcomes.

AI’s Growing Role in Dentistry:

The dental industry has been increasingly integrating AI into its practices. From identifying cavities to forecasting treatment results and designing artificial teeth, AI’s role is expanding. Its application in detecting gum inflammation signifies a transformative step in the diagnosis, treatment, and prevention of gum diseases.

Benefits of AI-aided Intraoral Photographs:

Dr. Reinhard Chun-Wang Chau, an HKU co-researcher, emphasized the advantages of combining AI technology with intraoral photographs. He believes that these images can guide patients to areas they might have missed during cleaning and encourage them to seek dental assistance sooner.

The Power of Interdisciplinary Collaboration:

This study exemplifies the potential of interdisciplinary research. By amalgamating expertise from diverse fields and regions, the team crafted an AI model proficient in detecting gum inflammation, bearing significant public health implications.

Future Endeavors:

Dr Lam envisions extending the AI system’s reach to community services, especially targeting the elderly and marginalized communities. The primary objective is to enhance oral health outcomes and bridge health disparities.
