Bournemouth extended their unbeaten run in the Premier League to four games after a stalemate with Brentford at the Vitality Stadium.
Chances were at a premium for both sides, although the hosts may have felt unfortunate not to be awarded a penalty in the first half.
Jordan Zemura burst onto the ball and looked to be tripped by Kristoffer Ajer's flailing leg, but referee Thomas Bramall decided to stick with his original decision despite being referred to the pitchside monitor.
Brentford had the better of the few opportunities in front of goal but Ivan Toney could only fire over the crossbar from close range after Josh Dasilva's cushioned pass.
The Cherries have now failed to score in their last three home games, despite stretching their unbeaten run to four games for the first time since October 2018.
The hosts remain 12th in the table, while the visitors drop down to 10th.
