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]
Before the cavity forms, the process is reversible, but once a cavity forms, the lost tooth structure cannot be regenerated. 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]
Oral hygiene practices involve the mechanical removal of plaque from hard tissue surfaces [24] Cariogenic bacteria levels in the plaque determine whether caries will occur or not, therefore, effective removal of plaque is paramount. [25] The removal of plaque inhibits demineralisation of teeth, and increases opportunities for remineralization.
The patients' age is not a limiting factor for the enamel microabrasion technique but in cases of not fully erupted teeth, it may be difficult to place rubber dam for the microabrasion process [8] Microabrasion is not indicated when discoloration is located in dentin such as in dentigenous imperfecta or tetracycline discoloration.
The tablets, sold over the counter in many countries, contain a dye (typically a vegetable dye, such as Phloxine B) that stains the plaque a bright color (typically red or blue). After brushing, one chews a tablet and rinses. Colored stains on the teeth indicate areas where plaque remains after brushing, providing feedback to improve brushing ...
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 ...
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
The purpose of polishing is to remove extrinsic stains, remove dental plaque accumulation, increase aesthetics and to reduce corrosion of metallic restorations. [ 1 ] [ 2 ] Tooth polishing has little therapeutic value and is usually done as a cosmetic procedure after debridement and before fluoride application. [ 3 ]
