FDA has cleared an Ortek Therapeutics 510(k) for the Ortek ECD, a lightweight tabletop device designed as an aid for dental professionals to diagnose and monitor dental cavities in the biting surfaces of molars and premolars. In clinical trials, the device detected the earliest forms of mineral loss in enamel well before an actual cavity was formed, the company says. It uses electrical conductance to diagnose and monitor enamel lesions. “When teeth begin to lose minerals, dentinal fluid from within the tooth percolates through the breached enamel site and enables the ECD to complete its electrical circuit,” the company says.
