Abstract:
Electroodontometric study of 756 intact teeth in 209 patients 18-65 years of age with normal periodontium and different stages of periodontal disease (periodontitis) showed that 96.8% of teeth in patients with mild periodontitis retained normal sensitivity, 68.4% -- with moderate periodontitis and 55% -- with severe periodontitis. Decreased pain threshold was detected in 3.2% of teeth of patients with mild periodontitis, 22.6% -- with moderate periodontitis and 12% -- with severe periodontitis. Increased pain threshold was not detected in teeth of patients with mild periodontitis, but in 9% with moderate periodontitis and in 29% with severe periodontitis it was obvious.

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.
