photoacoustic imaging

Engineering research at the University of California San Diego has led to a technique that could update how teeth and gums are imaged. Researchers combined squid ink with light and ultrasound to create a new dental imaging method to examine a patient’s gums in a more comprehensive and accurate way than existing methods and also non-invasive way. The image can show the entire pocket depth around teeth consistent and accurately without prodding the gums of the patient. The conventional method for dentists to assess gum health is to use an instrument called a periodontal probe which is a thin, hook-like metal tool that is marked like a tiny measuring stick and inserted in between the teeth and gums to see if the gums have shrunk back from the teeth, creating pockets. This method of measuring pocket depth is considered a … Read more
