Ireland scored seven tries to thrash Italy 46-7 in their Six Nations match in Dublin on Saturday.
The result improved Ireland's points difference to +81, which could prove to be vital if they go on to beat France in Paris next weekend.
Brian O'Driscoll, who will retire after the Six Nations, became rugby's most-capped Test player (140) and set up first-half tries for Jonathan Sexton and Andrew Trimble.
Ireland led 17-7 at the break and scored another five tries in the second half.
