People today ascribe a number of meanings to the Eye of Horus, including protection, wisdom, and revelation. It is often associated with the Eye of Providence found on US $1 bills and in Freemasonry iconography.
The crown, or visible part of the tooth, forms before the roots do. Eventually, the 20 primary teeth are replaced by 32 permanent teeth. The primary molars are replaced by permanent premolars (also called bicuspids) and the permanent molars come in behind the primary teeth. Most often, the first teeth to emerge are the lower two front teeth (incisors) and the upper and lower first molars, the molars closest to the front of the mouth. They are followed by the upper two front teeth.
Among deciduous (primary) teeth, ten are found in the maxilla (upper jaw) and ten in the mandible (lower jaw), for a total of 20. The dental formula for primary teeth is 2.1.0.22.1.0.2. In the primary set of teeth, there are two types of incisors â centrals and laterals, and two types of molars â first and second. All primary teeth are normally later replaced with their permanent counterparts.
