| Type | Number | Device | Decided |
|---|---|---|---|
| * | DEN990002 | Kavo Diagnodent Our reading of the summary gave K983658, which is not in FDA’s 510(k) list. The device the summary names is FDA’s De Novo DEN990002, Kavo Diagnodent (Kavo America), granted Feb 22, 2000; older De Novo requests were first filed under a 510(k) number, so this links to the grant. | 2000 |
