Uranium is a naturally occurring weakly radioactive element. High levels of uranium in water may increase the risk of cancer and kidney damage. Most of the uranium that is ingested by food or drink by the human body is excreted, but some amounts are absorbed into the bloodstream and kidneys.
Education and Training for Oral Surgeons. To be certified as a diplomate of the American Board of Oral and Maxillofacial Surgery, an oral and maxillofacial surgeon (commonly called an OMFS or oral surgeon) must graduate from an accredited dental school and be licensed in the state in which he/she is practicing.
Dental school is typically four years (U of Pacific is three years). To specialize into ortho or oral surgery is after that but must be determined during your four years in dental school (sort of like picking a major in college). If you do decide to specialize it may be up to three more years of school and a residency before you get out on your own.
