Toothbrush-Sized Ultrasound Transducer for Painless Gum Disease Screening

Scientists have developed a toothbrush-shaped ultrasound transducer for a less invasive way to screen for gum disease. In tests on animal tissues, this miniaturized device produced results comparable to traditional manual probing. Its small size allows easy access to molars and premolars, while its high-frequency operation provides high-quality images, overcoming limitations of larger transducers. This innovative tool promises a more comfortable and effective approach to diagnosing and treating gum disease.
