The second-rower will be looking to make a big impact against the Men of Gwent and may come up against former team mate Richard Hibbard.
"We've had a great couple of months with lots of hard work so hopefully now it is going to pay dividends.
"There is definitely an extra buzz around the place this week knowing we have a game coming up, the sessions have been sharper and more focused."
Denton who also played 40 times for Leinster added: "The Dragons have a lot of quality throughout their squad so it will be a big test for us but an important one with the Championship season approaching."
