Green and yellow stains on anterior teeth are associated with poor oral hygiene and what type of bacteria?

Pseudomonas
S. mutans
Chromogenic
Actinomyces

The correct answer is: Chromogenic

The answer is C Chromogenic. This type of bacteria can cause stains on teeth due to its pigmentation properties, which can result in green and yellow stains on anterior teeth. This is often associated with poor oral hygiene and can be prevented by practicing good oral hygiene habits and visiting the dentist regularly. Options A, B, and D are all types of bacteria that can be found in the mouth, but they are not directly responsible for causing these specific types of stains. Pseudomonas, for example, is commonly found in soil and water and can cause infections in other parts of the body, but not typically in the mouth. S. mutans is known for causing tooth decay and cavities, while Actinomyces is associated with causing tooth infections and abscesses. Overall, while these bacteria can contribute to poor oral health, they are not directly responsible for the green and yellow stains on teeth.
