ORIENT succumbed to a fourth straight defeat without scoring when Ryan Lowe's first half goal gave Milton Keynes Dons the points at stadiummk.
Lowe's close range goal came at the end of a first period that the Dons dominated and could have had more from.
Orient improved after the break and David Mooney was denied three times by home keeper David Martin before Kevin Lisbie had a final minute effort ruled out.
It wasn't to be for the Londoners as the minutes without a goal continue to rack up.
Milton Keynes began on the front foot that they were to occupy for the majority of the opening period and twice got in behind the O's inside the first few minutes.
Luke Chadwick had their first opportunity but shot straight at Ryan Allsop when one-on-one with the O's keeper.
Then Chadwick turned provider, slipping a ball through to Dean Bowditch, but the Dons man took a heavy touch and allowed Allsop to sweep up the danger.
With 12 minutes on the clock, Allsop was less assured in dealing with a long range Angelo Balanta effort, as the ball squirmed out of his grasp and onto the post, but luckily for the O's it bounced back into the keeper's hands.
The game was being played at a rather low-key pace, but the home side were dominating possession and had another half chance on 20 when a corner was only headed half clear and Darren Potter fired harmlessly over on the volley.
Allsop was called into action again just after the half hour when Martin Rowlands was caught in possession inside the O's half and the Dons advanced possession to Lowe.
He did well to make space for himself as he entered the box, but Allsop got an excellent hand to his fierce shot to push it over the top and to safety.
A Dons breakthrough was on the cards though so it came as little surprise when it arrived four minutes before the interval.
Lowe was the man to finish, knocking home from close range after Bowditch got in down the right to supply an inviting low cross.
Moses Odubajo had a shot well blocked by home defender Anthony Kay as half time neared, but the hosts were comfortable in their lead at the break.
The O's came out at the start of the second period with a real purpose, however, and three chances came Mooney's way in the first eight minutes after the restart.
First he latched onto a cross from Odubajo and drilled goalwards, but keeper David Martin was able to block by his near post.
Then Lee Cook ran forcefully at the Dons backline and slipped the ball to Mooney, but Martin dived down well to his right to smother.
Finally, Orient caught the hosts in possession as they looked to play out and Cook feeds the striker again, but his right footed shot was directed straight at Martin and the Dons escaped.
Following that burst of activity, the O's were then squeezed out of the game again as it became more and more scrappy.
They were grateful for a fine save from Allsop to keep them in it midway through the half when Balanta pulled the ball back for Chadwick by the penalty spot, and his low drive was somehow diverted over the bar by the O's keeper.
Kevin Lisbie and Dean Cox came off the bench for the away side as they continued to search for that elusive goal.
In stoppage time they thought they had it when Cook's corner was knocked home by Lisbie, but it was with his hand rather than his head and it remained 1-0 to the Dons.
