Dragons began life after coach Paul Turner with a 30-22 victory over Magners League rivals Edinburgh in a thrilling clash at Rodney Parade.
Turner was relieved of his duties on 28 January while the Dragons conducted "various investigations", with a disciplinary hearing expected.
His departure from the Welsh region was rubber-stamped earlier this week and Edinburgh drew first blood when a smart kick by Tim Visser allowed fellow wing Lee Jones to touch down for a try which Chris Paterson converted.
A clever switch of direction by Jason Tovey paved the way for a score by Dragons' prop Phil Price before Paterson kicked Edinburgh into a 10-5 lead with a 22nd minute penalty.
The Dragons roared back to claim three tries in the second quarter, starting when Will Harries put Tovey over.
A powerful forward surge brought a try for Lewis Evans, converted by Tovey and a kick by Harries put Ashley Smith over to make it 22-10 at the interval.
Tovey stretched the Dragons' lead with a penalty after 45 minutes and flanker Andrew Coombs burst away from a maul after a lineout for their fifth try of the match.
Edinburgh hit back with a break by Visser and after several phases close to the home line, it was Visser who fought his way over for a try.
In the dying seconds of the game Geoff Cross forced his way over for the third Edinburgh try which Paterson converted but it was not enough to claim a losing bonus point.
