Tebaldi suffered an ankle injury in January but after missing out on Italy's opening three matches of the RBS 6 Nations, he is back in the fold.
As one of two scrum-halves in the 30-man Italy squad - Jacques Brunel names his matchday squad on Thursday - Tebaldi is set to play some part against Ireland, having last featured for the Azzurri in the summer of 2012.
In his first season since his move to the Ospreys, Tebaldi has caught the eye and while his ankle injury was untimely, he believes his move to Wales has paid dividends.
"I have been growing as a presence in the field, at the level of control of the game at certain moments where maybe before I could lose myself in something foolish," said 26-year-old Tebaldi.
"I have a greater focus and I analyse the details that emerge from pre-and post-game video. It's a 'perfectionist style', and typically Anglo-Saxon.
"Besides being on the sea, Swansea has some very beautiful places around. The Gower Peninsula is a popular holiday resort. There are beautiful beaches."
