Which type of stain is relating to the use of betel leaves?

• A. Intrinsic stain
• B. Exogenous stain
• C. Chlorhexidine stain
• D. Orange stain

Answer: (B)

Betel leaves, commonly used in various cultural practices and chewing habits, can lead to discoloration of the teeth due to the substances contained in them. The type of stain that arises from external sources, such as food, beverages, or other substances, is classified as an exogenous stain. This means that the stain originates from outside the tooth structure, resulting from external application or dietary habits. In the case of betel leaves, their complex mixture of ingredients can deposit onto the tooth surface, leading to staining that occurs externally rather than from within the tooth itself. This external nature of the stain is the hallmark of exogenous stains. Other stain types, such as intrinsic stains, originate from within the tooth and are often the result of factors like genetics, aging, or dental trauma. This distinction is key in understanding how different stains are formed and treated in dental hygiene practices.
