In order to become an orthodontist, students need to complete four years of dental school. Coursework in dental school includes anatomy, physiology and microbiology, as well as classes that apply more specifically to orthodontics, such as dental anatomy and occlusion, pediatric dentistry and dental materials.
This article is about the color. For other uses, see Purple (disambiguation). Purple is a color intermediate between blue and red. It is similar to violet, but unlike violet, which is a spectral color with its own wavelength on the visible spectrum of light, purple is a composite color made by combining red and blue.
Blue represents birth, purple represents a transition to royalty, green represents the growth of youth, orange represents strength and maturity, white is purity, and violet -- the last stage before the red and black room representing death in the story -- represents the knowledge and wisdom that comes with age.
