Aim:
To obtain baseline knowledge of levels of dental caries in 12-year-old children residing in areas with varying levels of fluoride in drinking water in Pakistan; and to observe a dose-response relationship between the prevalence of dental caries at different concentrations of fluoride in drinking water.
Method:
Clinical examination of children and analysis of samples of drinking water.
Results:
The maximum reduction of caries in relation to fluoride levels in Pakistan was witnessed between the fluoride concentrations of 0.00-0.33ppm.
Conclusions:
There are no gold standards for setting up a universal optimal level of fluoride in drinking water and each country needs to determine the concentration of fluoride in their drinking water in accordance with its socio-economic and climatic conditions, dietary and oral hygiene habits of its population, and local research to determine how much fluoride is beneficial in the control of caries.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
