Table/index And Page Mapping

I've just found a blocking lock occuring in a SQL Server.
[color=blue]
>From the waitresource, I found that the blocker has the following[/color]
information:
wait_info: PAGEIOLATCH_EX
wait_resource: 14:1:564312

And the blockee has the following information:
wait_info: LCK_M_S
wait_resource: KEY: 14:405576483:2 (7501a5aa8355)

The problem is that I do not know which object is the blocker holding,
for I understand that for a PAGE lock, it is in the format of
database_id:file_id:page_id

I know the db_id, the file_id but don't know how to map the page_id
(564312) to a table/index in the database.

Can somebody shed some lights on this? thks a lot.
