Could a 3D scanner replace the dental plaque check?
NCT ID NCT07152314
First seen Jun 26, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
This study tests whether a 3D intraoral scanner can accurately measure dental plaque compared to the traditional method of applying a dye and visually scoring. Twenty adults with at least 20 natural teeth and visible plaque will be scanned before and after plaque disclosure and after brushing. The goal is to see if the digital method matches the standard clinical plaque index.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- intraoral scanner imaging
- What this could lead to
- If successful, this could provide a faster, more objective way to measure dental plaque, potentially improving diagnosis and monitoring of gum disease.
- What could go wrong
- This is a small, early-stage study with only 20 participants. The digital method may not prove accurate enough to replace traditional plaque scoring, and results may not apply to everyone.

Who is studied
Recruitment will be carried out through different communication channels, including informative posters distributed in the dental clinics of UnG, digital dissemination on the university's official website and its institutional social networks, direct invitation to patients who are on the waiting list of the periodontics clinic, and dissemination by the professors of the undergraduate and graduate clinics. All promotional materials will clearly state the inclusion and exclusion criteria, as well as provide contact information for scheduling, initial screening, and the ethics committee approval number. All participants will attend the Center for Clinical Studies of Univeritas UnG.
