It is derived from the Greek words leuko ("white") and nychia ("nails"). The most common cause is injury to the base of the nail (the matrix) where the nail is formed . </P> <P> It is harmless and most commonly caused by minor injuries, such as nail biting, that occur while the nail is growing . Leukonychia occurs most commonly in healthy individuals, unrelated to any known nutritional or physiological deficiency . When caused by injury the marks will disappear as the nail grows outwards, however a dietary deficiency will cause recurrent leukonychia . </P>
