Buffon saves Juventus' unbeaten run
Gianluigi Buffon kept out Francesco Totti's second-half penalty to extend Juventus' unbeaten run in Serie A to 14 games.
Daniele De Rossi had put Roma ahead in the fifth minute before Giorgio Chiellini equalised on the hour mark.
Roma had a chance to go in front two minutes later but Totti's central spot-kick was saved by Buffon.
The Turin giants climbed back to the top of the standings with the draw and are level on 30 points with Udinese.
Roma, who went into the game at the Stadio Olimpico on the back of two straight defeats, dropped to ninth.
Juventus picked up where they left off after the re-start and levelled in the 61st minute when Chiellini headed Estigarribia's cross-shot past Stekelenburg.
Roma could have gone back in front one minute later after Vidal brought down Erik Lamela in the area. Totti struck the resulting spot-kick with power but right down the middle and Buffon kept it out.
Juventus then had an opportunity to take all three points with two minutes remaining when Eljero Elia found substitute Fabio Quagliarella in the box and his strike was saved by Stekelenburg.
