One thing you can do is:
1.Back up your database
2. Make a script to create all table references.
3. Make a script to drop all table references.
4. Make a script to truncate all tables, except the ones you want to keep
Restore your backup in a new database, and use this new database for testing your scripts.
First drop all table references, second run the truncate script and third restore al the table references and probe your database integrity
Hope it helps you
