teewai at WASET 2026: Presenting AI Shade Matching to the Dental Research Community

In September 2026, teewai’s approach to AI-assisted tooth-shade matching was presented at the 20th International Conference on Dentistry and Oral Health, organized by the World Academy of Science, Engineering and Technology (WASET) in Rome. The conference is a peer forum for dental and oral-health research, bringing together clinicians, materials scientists and engineers working on digital dentistry, shade science and oral diagnostics.

The presentation focused on teewai’s method for mapping a single phone photo to the VITA Classical shade scale. The core idea: read enamel color in CIE Lab coordinates — the same space used in dental spectrophotometry — rather than in device RGB, then match the L*, a*, b* point to the nearest calibrated VITA shade. Doing this on a phone, without a clinic spectrophotometer, is what makes shade measurement accessible outside the operatory.

Two points drew the most discussion. First, the decision to analyze the raw captured color rather than color-correcting the photo — early normalization experiments inflated whiteness scores by lifting darker frames, so teewai deliberately avoids it. Second, the role of a white reference card as a calibration anchor, which materially improves agreement with clinical shade guides. Both choices trade a little convenience for measurement honesty.

Presenting at a peer research conference is part of how teewai stays grounded in dental science rather than marketing claims. The feedback from clinicians and researchers feeds back into the scoring model and the recommendations engine — so the app you use benefits from the same scrutiny the method gets in the room.
