Black-line stain has a very different origin and requires an alternate method of removal. This stain is calculus-like and forms along the gingival third of the tooth near the gingival margin. Black line stain is seen in patients of all ages, yet is more common in women and in patients with good oral hygiene. There appears to be a natural tendency to forming black line stain as it often reforms despite regular self-care. The quantity of black line stain may be less when plaque biofilm is eticulously removed.3 Black line stain is firmly attached to the teeth and often requires moderate scaling to be removed. from: http://www.dimensionsofdentalhygiene.com/print.asp?id=468
