A basic stain stains the bacteria (the stain is a positively charged molecule that attaches to cells which are negatively charged or to negatively charged molecules in cells.) A negative stain does not stain cells (why its called a negative stain), it stains the background around the cells.
Causes of Intrinsic Staining. Intrinsic staining can occur either before the teeth have emerged, while they are still developing, or after they have emerged. Pre-eruptive staining, which occurs while the teeth are developing, is most often caused by medications or by fluoride. The most common causes of pre-eruptive intrinsic staining are excess fluoride intake either by the mother during pregnancy or by the child while the permanent teeth are developing. Tetracycline, an antibiotic, is also a common cause of this type of discoloration. Post-eruptive staining occurs after the teeth have emerged. The most common causes of this kind of intrinsic staining are trauma and extrinsic staining that reaches the inner layers of the teeth through cracks or surface damage. Trauma can create intrinsic discoloration when blood from a damaged pulp fills the small tubes inside the tooth.
