Tooth Tattoo: A New Paradigm to Detect Bacteria on Teeth Enamel
Oral health is an integral part of good overall health. Dental caries and periodontitis are the most common chronic infectious oral diseases. With a greater understanding of dental caries and periodontal diseases comes an opportunity to promote ‘preventive & interceptive therapy’ much before the onset and progression of the disease. Central to this is early diagnosis. But many yester year diagnostic tools lack selectivity and sensitivity and others being expensive, limit the opportunity for early diagnosis. Researchers at Princeton University, New Jersey led by Micheal McAlpine and Tufts bioengineers Fiorenzo Omenetto, David Kaplan and Hu Tao have developed a tiny graphene nanosensor device for early and highly sensitive detection of bacteria on human enamel and assess patient’s oral health, which they have called Tooth tattoo. The team first published their research in the journal, Nature Communications. Presently the prototype being studied, represents versatile approach just not for caries and periodontal disease detection but could provide window to patient’s overall health.
