What color stain is typically caused by tar?

1. Brown

2. Green

3. Red

4. Blue

The correct answer is: Brown

The typical color stain caused by tar is brown. This is a result of the natural properties of tar, which usually comes from the combustion of organic materials, such as tobacco or other plants. When tar comes into contact with teeth, it can leave behind a dark brown stain that can be difficult to remove. Understanding this can be particularly important in dental hygiene and coronal polishing, as it highlights the necessity of effective cleaning techniques to remove such stains. Other colors mentioned, like green, red, and blue, are usually associated with different substances or stains, but brown is distinctly linked to the presence of tar. Thus, being able to identify the characteristic stains caused by various substances is crucial for effective dental care and maintenance.
