Teeth brown staining

Chlorhexidine may cause brown staining of the teeth and therefore patients are advised not to use chlorhexidine on a long-term basis. 

Several methods have been developed for quantifying dental fluorosis. The most commonly used method is Dean s index [49], which classifies fluorosis on a scale of 0 to 4 as follows class 0, no fluorosis class 1, very mild fluorosis (opaque white areas irregularly covering <25% of the tooth surface) class 2, mild fluorosis (white areas covering 25-50% of the tooth surface) class 3, moderate fluorosis (all surfaces affected, with some brown spots and marked wear on surfaces subject to attrition) and class 4, severe fluorosis (widespread brown stains and pitting). The average score of the two most severely affected teeth is used to derive the classification. Other commonly used methods to rate dental fluorosis include the Thylstrup-Fejerskov Index (TFI) [50] and the tooth surface... 

Tannins are responsible for the brown stains in coffee mugs or on a coffee drinkers teeth. Because tannins are acidic, they can be readily removed with an alkaline cleanser. Use a little laundry bleach on the mug, and brush your teeth with baking soda. 

The relationship between fluoride and dental caries was first noted in the early part of the 20th century when it was observed that residents of certain areas of USA developed brown stains on their teeth. In the 1930s, it was observed that the prevalence and severity of this type of mottled enamel was directly related to high amounts of ingested fluoride [34],... 

Yellowish-brown staining of the teeth was related to imi-penem in several cases (26,27). Staining was mostly removable with dental assistance. 

The effects of fluorides in preventing tooth decay were first observed by a young dentist named Frederick S. McKay in Colorado Springs, Colorado, in 1901. McKay noticed that many of his patients had unattractive brown stains on their teeth. But the rate... 

The supposed human remains were accompanied by flint implements and animal teeth, all of which apparently supported the early date attributed to the find. The flint implements were of a reddish color, matching that of local flints, but spectrographic analysis revealed that they had been artificially stained with chromium and iron salts below the layer of stain there was a white crust, whereas local flints were brown throughout. The animal teeth also seemed to have been "planted" at the burial site so as to suggest an early date the red-brown color of the teeth had also been artificially stained chromium and iron had been found when they were analyzed. A hippopotamus tooth, previously supposed to be contemporary with the tool carved from the elephant s tusk, was also stained with chromium and iron salts and contained little fluorine. 

Some cities add fluorides to their water supply. By doing so, they hope to improve the dental health of everyone living in the city. Young people, whose teeth are still developing, benefit the most. The process of adding fluorides to public water supplies is called fluoridation. Too much fluorine in the water leads to a light brown and permanent staining of teeth. 

The cKent should be warned that the urine might turn brown. This color will disappear when the client is no longer taking the medication. If the cKent is taking an oral suspension, the muse should instruct to rinse the mouth after taking the medication to prevent staining of the teeth.
