The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions. [8]
The most acknowledged theory for supernumerary teeth is hyperactivity of dental lamina. [6] On completion of the dentition, the dental lamina is usually destroyed and reabsorbed, but when remnants fail to resorb, it can continue to proliferate abnormally. This abnormal proliferation can form the extra tooth bud leading to supernumerary teeth ...
The agents most commonly used to intrinsically change the color of teeth are hydrogen peroxide and carbamide peroxide. Oxygen radicals from the peroxide in the whitening agents contact the stains in the interprismatic spaces within the enamel layer. When this occurs, stains will be bleached and the teeth now appear lighter in color.
Hematoxylin staining shown as "basophilic" at top, seen with dual staining with hematoxylin and eosin (H&E). Haematoxylin stain is commonly followed (or counterstained) with another histologic stain, eosin. [10] [11] [1] When paired, this staining procedure is known as H&E staining, and is one of the most commonly used combinations in histology.
Teeth affected in this way are also usually more susceptible to further staining acquired throughout life. Amelogenesis imperfecta is a rare condition that affects the formation of enamel (amelogenesis). The enamel is fragile, the teeth appear yellow or brown, and surface stains build up more readily. [1]
A basophil granulocyte is surrounded by lightly staining eosinophilic erythrocytes in an H&E staining. Eosinophilic (Greek suffix -phil-, meaning loves eosin) is the staining of tissues, cells, or organelles after they have been washed with eosin, a dye. Eosin is an acidic dye for staining cell cytoplasm, collagen, and muscle fibers.
The nicotine and tar in tobacco, combined with oxygen, turns yellow and over time will absorb into the pores of enamel and stain the teeth yellow. The dark brown to black stains along the gum line of the teeth are the result of the porous nature of calculus immediately picking up the stains from nicotine and tar. Betel chewing. [12] Betel ...
Universal numbering system. This is a dental practitioner view, so tooth number 1, the rear upper tooth on the patient's right, appears on the left of the chart. The Universal Numbering System, sometimes called the "American System", is a dental notation system commonly used in the United States. [1] [2]
