Researchers from the Privolzhsky Research Medical University (PIMU) have developed a new method for the rapid diagnosis of tooth decay, based on technologies used in ophthalmology.
They explained that detecting early-stage cavities is challenging because they often present no symptoms, leading to delayed treatment. While X-rays can be helpful, they do not always provide precise information about the extent of enamel damage.
The scientists proposed diagnosing cavities using optical coherence tomography (OCT), a technique widely used in ophthalmology to assess the retina’s condition. This method is “non-invasive, quick, and painless.”
The Institute of Applied Physics of the Russian Academy of Sciences has developed a device capable of distinguishing early forms of cavities from dental plaque by analyzing the OCT signal attenuation coefficient. In simple terms, a light beam is directed at the tooth, reflected, and specialists can then evaluate the condition of the structures based on the reflected light.
PIMU highlighted that the new method not only determines the extent of damage but also accurately delineates its boundaries.
