A lesion that appears dark brown and shiny suggests dental caries were once present, but the demineralization process has stopped, leaving a stain. Active decay is lighter in color and dull in appearance. [14] As the enamel and dentin are destroyed, the cavity becomes more noticeable. The affected areas of the tooth change color and become soft ...
Wright's stain. The mesothelium is composed of an extensive monolayer of specialized cells (mesothelial cells) that line the body's serous cavities and internal organs. The main purpose of these cells is to produce a lubricating fluid that is released between layers, [ 4 ] providing a slippery, non-adhesive, and protective surface to facilitate ...
The staining occurs in the interprismatic region internally on the enamel, which causes the tooth to appear darker or more yellow overall. In a perfect state, enamel is colorless, but it does reflect underlying tooth structure with its stains since light reflection properties of the tooth are low.

Cross-section of a tooth. B is dentin. Dentin (/ ˈ d ɛ n t ɪ n / DEN-tin) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / DEN-teen or / ˌ d ɛ n ˈ t iː n / DEN-TEEN) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth.
Comparison of alphanumeric notation, Palmer notation, ISO 3950 (FDI) notation, Universal Numbering System, and paleoanthropology notation. Dental professionals, in writing or speech, use several different dental notation systems for associating information with a specific tooth.
There are two main methods of detecting dental plaque in the oral cavity: through the application of a disclosing gel or tablet, and/or visually through observation. Plaque detection is usually detected clinically by plaque disclosing agents. Disclosing agents contain dye which turns bright red to indicate plaque build-up. [1]
Amalgam fillings often stain the tooth they are placed in. [11] This is most noticeable in very old fillings, as pigment slowly leaches out of the amalgam filling material and its associated corroded surfaces. In addition, metallic fillings cast a shadow that can be visible through the tooth and make it appear darker.
