What Shinu suggested should work, though I wouldn't use !important.
I should also note that we do not apply bullets of that kind. Quite the contrary -- we remove them, as styles for bullets are hard to work with and the standard defined bullets offer little or no customization depending on the browser.
Perhaps you could provide me with a live URL so I could see your exact case and why the bullets are appearing.
All the best,
the Telerik team
