A dental disease characterized by mottling of teeth is due to the presence of which chemical element in drinking water?
Correct answer: A. Fluorine
- A. Fluorine
- B. Boron
- C. Mercury
- D. Chlorine
Explanation
The dental disease characterized by mottling of teeth is known as "dental fluorosis." It is caused by the excessive presence of the chemical element "fluoride" in drinking water. Dental fluorosis is a cosmetic condition that affects the appearance of teeth, leading to white or brown spots, streaks, or pitting on the tooth enamel. It occurs when individuals are exposed to high levels of fluoride during the development of their teeth, typically in childhood. The condition is most often associated with the consumption of water with elevated natural fluoride levels or the use of excessive fluoride-containing dental products.
