This would actually be called moonlighting because as an OMFS resident you are employed by the hospital that you work with. Some programs look down on it some do not. Either way, you will be pretty busy and may only be able to work 1-2 saturdays a month due to time restraints. It is not like dental school at all. You go to work at like 5:30 a.m., leave? (when the work is done), you are on call a lot, you are studying, reading, making presentations, running clinics, doing off service rotations in things like anesthesia, surgery, medicine. Some residents do it but not a lot.
