England's captain says that Ben and Jonny Bairstow could play as specialist batters in the final Test because of injuries.
Bairstow was hit on the hand while scoring his century in the first day of the fourth Test, while Ben Stokes picked up a side strain.
England earned a draw in the series and avoided a big defeat.
"We have to see where they are," said Root.
We have to assess everyone and see what their bodies can handle.
"You can pick both of them as a bat and batter as well - both of them have been playing as a batter."
England will have to make at least one change for the day-night Test, which starts at 04:00 GMT on Friday, after Buttler flew home with a broken finger.
The 30-year-old is in contention to make his Test debut, after being seen working hard on his wicketkeeping during Wednesday's practice.
He has a good understanding of the country.
He brings a lot of energy when he's around the group and he loves cricket.
He'll put everything into it if he gets his chance.
We must harness the last-day performance.
Stuart Broad and James Anderson saw out the final 12 balls of the match to earn a draw as England were all out for 91 on the final day of the fourth Test.
The performance needs to beharnessed and taken forward.
It shows a lot about where we're at as a team, if you look at the week that we had, whether it be Covid leading into the game, a couple of injuries that we had to manage throughout the game as well, it shows a lot about where we're
We showed a lot of character after three very difficult games where we've underperformed and not shown the best of our skills, so it's definitely something for us to build on moving forward.
The desire, the fight and the pride that everyone showed out there, is something that we have to harness and we have to play with more frequently throughout five days.
We have proven to ourselves that we can do that now.
I won't be asking for a rest.
Australia have fitness concerns of their own, with Mitchell Starc and Scott Boland set to be assessed.
Starc, who is the only pace bowler on either side to play in the four Tests so far, says he is not looking for a break.
When asked if he was carrying any injuries, Starc said it was up to the selectors.
I'm feeling good. I would like to play. I won't be requesting a rest.
Should Starc or Boland be ruled out, Jhye Richardson and Michael Neser will be in Australia's squad.
Australia have decisions to make about their batting line-up. After missing the fourth Test with Covid, Head is able to return, but his replacement, Khawaja, made twin centuries.
