The surge of interest in testing for the COVID-19 pathogen has led to some innovative tests and test strategies, including at-home tests. However, the FDA has indicated that it is wary of both at-home testing and specimen collection in other than supervised settings, a policy that is meeting with criticism from some quarters, but not all.

San Jose, Calif.-based Align Technology Inc. has won the FDA’s nod for its Itero Element 5D imaging system. The company said the Itero Element 5D is the first intraoral scanner with near-infrared imaging (NIRI) technology that visualizes the internal structure of the tooth in real time. The FDA cleared the device for the detection of interproximal caries lesions above the gingiva and for monitoring the progress of such lesions.
