The right deciduous maxillary central incisor is known as "E", and the left one is known as "F". The permanent maxillary central incisors are designated by a number. The right permanent maxillary central incisor is known as "8", and the left one is known as "9". [4] [page needed]
During the developmental stages, the permanent tooth germ, specifically of the maxillary incisor lies superior to the apex of the primary incisor. [5] If there is damage to the primary incisor, this will cause an impact on the permanent incisor as well as there is only about a 3mm space of thickness between the primary and permanent teeth. [5]
Its causes can be the same as other forms of enamel hypoplasia, but it is most commonly associated with trauma to a primary maxillary central incisor and the subsequent developmental disturbance of the underlying permanent tooth. [21] This may also result in dilaceration of the root of the permanent tooth. [22]
There are 32 permanent teeth and those of the maxillae (on the top) erupt in a different order from permanent mandibular (on the bottom) teeth. Maxillary teeth typically erupt in the following order: (1) first molar (2) central incisor, (3) lateral incisor, (4) first premolar, (5) second premolar, (6) canine, (7) second molar, and (8) third molar.
It often appears between the roots of the maxillary central incisors. Radiographically, it may often appear as a heart-shaped radiolucency. It is usually asymptomatic, but may sometimes produce an elevation in the anterior portion of the palate. It was first described by Meyer in 1914. [1]
Such tooth avulsion was the intentional removal of one or more teeth, which was done for ritual or aesthetic reasons. It was also used to denote group affiliation. Typically, the maxillary incisors were the teeth most often selected for removal. This practice is still common in parts of Africa. [48]
Incisors are divided further into central and lateral incisors. Among premolars and molars, there are first and second premolars, and first, second, and third molars. The side of the mouth in which a tooth is found may also be included in the name. For example, a specific name for a tooth may be "permanent maxillary left lateral incisor."
Permanent teeth or adult teeth are the second set of teeth formed in diphyodont mammals.In humans and old world simians, there are thirty-two permanent teeth, consisting of six maxillary and six mandibular molars, four maxillary and four mandibular premolars, two maxillary and two mandibular canines, four maxillary and four mandibular incisors.
