If you have a clean backup (one without any corruption) and an unbroken chain of log backups up to present, you can do a page restore. Or you can restore the full backup over the DB followed by all log backups to bring the DB back to current time with no corruption (take a tail-log backup first).

If the DB is not in full recovery or you don't have the necessary log backups, then you're looking at either losing data by restoring to the last good backup or by repairing. You can, in that case, try to repair then restore a copy of the DB elsewhere and sync in the missing data.
