Chemical analysis of sound and carious enamel of permanent tooth
1Head of Pedodontics and Preventive Dentistry, Dr. R. Ahmed Dental College, Calcutta, India.
Abstract:
Enamel consists mainly of inorganic material (96%) and only a small amount of organic substance and water (4%). The inorganic material is similar to apatite. The originally found apatite mineral remains basically unchanged except at the surface in contact with the oral tissues, where diffusion processes operate. Enamel reflects the trace element environment present in the tissue fluids at the time of tissue development. These are variations of types and concentration of inorganic elements found in permanent and deciduous enamel. Variations are also seen in sound and carious enamel.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...

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.
