If you already tried restoring a backup you may have another things to do, but it seams that it's corrupted.
Try one or all this ideas:
Restore a backup with other name for the database.
Data and objects transfered to other database.
Detach and attach the database with a new name.
Once the tables containing errors identified, try to run
DBCC CHECKTABLE with option REPAIR_REBUILD or even REPAIR_ALLOW_DATA_LOSS. the last one can result in data loss, so be sure to run it within a transaction (if data loss occurs make a rollback)
If all your backups are corrupted you don't have too many options, so good luck...

I ran dbcc checkdb before and the same errors were displayed. I tried dbcc checkalloc and an error was displayed on the object ID 99. But this objects not exist anymore.
My solution (a bit boring) is creating a new database and use export data in order to export the entire database's objects. I tried to restore from full backup, but the errors exist in the backup.
