[Characteristics of dental enamel and its resistance to caries]
Abstract:
Systematical research of basic texture characteristics (specific surface area, specific volume and size of micro-, meso- and macropores, porosity) of intact dental enamel of persons with various degree of resistance to caries has been performed using methods of adsorption and Hg-porosimetry. Studied objects have been shown to be small-porous (total porosity epsilon = 4-6%), roughly-dispersed (specific surface S6ET = 0.7-1.5 m2/g) materials. Regularities of changes of specific surface and porous structure in researched samples have been established. More mesoporous enamel structure has been shown to form in the series of samples varying from high level of resistance to very low level. Meanwhile intact dental enamel has the same degree of macroporosity irrespective of the level of its resistance to caries. Micropores within the samples have been established to be heterogenous and their volume to be very insignificant (2-4 x 10(-9) m3/g). Substantiation of various degree of resistance of intact dental enamel to carious process has been suggested within the framework of structurally-geometrical approach.

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...

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.
