Dental students can obtain either a Doctorate of Dental Medicine (DMD) or Doctorate of Dental Surgery (DDS). DMD and DDS are equivalent degrees, and both programs consist of the same four-year curricula. The first two years are comprised of natural and clinical science instruction in classrooms and laboratories.

The word ignorant is an adjective describing a person in the state of being unaware and is often used as an insult to describe individuals who deliberately ignore or disregard important information or facts.
For example ignorance of a law which has not yet been promulgated. Ignorantia juris non excusat or Ignorantia legis neminem excusat is a Latin maxim which means ignorance of the law does not excuse or ignorance of the law excuses no one. The rationale of this maxim is that if ignorance of law was an excuse then any person charged with a criminal offense or subject of a civil suit can claim that he or she was unaware of the law in question and avoid liability.
