Thank you.Off the top if my head ost_ticket, ost_ticket__CDATA, ost_attachment, ost_file, ost_file_chunk, ost_ticket_thread, ost_form_entry_values.. there are probably more. Personally I would back up the database first, drop the database, and then restore the ost_config, and other tables that I was sure have nothing to do with tickets and work that way instead,.
