Setup Route To Not Push Onto History Stack

How would I setup routes so it doesn’t push onto the history stack and add the back button.

The specific example I have is having a log in page redirect to a root view, but not having the back button displayed on the root view.

Here is the route code I have:

$stateProvider

  .state('login', {
    url: '/login',
    templateUrl: 'client/views/login.tpl'
  })

  .state('root', {
    url:'/root',
    templateUrl: 'client/views/root.tpl'
  })
