Publications

With over 12 years of research and over 60 peer-reviewed publications on The Canary System™, the science supporting the technology behind The Canary System™ is the cornerstone of Quantum Dental Technologies. Ensuring robust and quality-driven data is as important to our users and patients as it is to us. To that end, we have engaged in two investigational studies approved by Health Canada. The purpose of these studies is to ensure that The Canary System™ is safe and effective in detecting early tooth decay. For more information on our studies, see below:
