Abstract:
Two hundred eighty children including wellnourished, malnourished and infants with intrauterine growth retardation (IUGR) were examined for dental eruption and enamel hypoplasia. In malnourished and IUGR children eruption of teeth was delayed. The prevalence of enamel hypoplsia in wellnourished children was 20% being significantly higher in females as compared to males in age group 1-2 years. Enamel hypoplasia was seen in 36.6% malnourished subjects. Breast-feeding was protective against enamel hypoplasia.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
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.
