When this tooth is newly erupted into the mouth, the incisal edges have three rounded features called mammelons. [10] Mammelons disappear with time as the enamel wears away by friction. Generally, there are gender differences in the appearance of this tooth. In males, the size of the maxillary central incisor is larger usually than in females.
The maxillary teeth are the maxillary central incisors (teeth 8 and 9 in the diagram), maxillary lateral incisors (7 and 10), maxillary canines (6 and 11), maxillary first premolars (5 and 12), maxillary second premolars (4 and 13), maxillary first molars (3 and 14), maxillary second molars (2 and 15), and maxillary third molars (1 and 16).
Bolton Analysis is a tooth analysis developed by Wayne A. Bolton to determine the discrepancy between size of maxillary and mandibular teeth. This analysis helps to determine the optimum interarch relationship. This analysis measures the Mesio-distal width of each tooth and is divided into two analyses. [1] [2]
The maxillary second molar is the tooth located laterally from both the maxillary first molars of the mouth but mesially from both maxillary third molars. This is true only in permanent teeth. In deciduous teeth, the maxillary second molar is the last tooth in the mouth and does not have a third molar behind it.
The right permanent maxillary first molar is known as tooth "3", and the left permanent maxillary first molar is known as tooth "14". In the Palmer notation, a number and symbol are used to identify the tooth. The number identifies the tooth position relative to the midline, and the symbol identifies the quadrant of the mouth.
A single tooth is smaller than normal. [3] Localized microdontia is far more common than generalized microdontia, [2] and is often associated with hypodontia (reduced number of teeth). [1] The most commonly involved tooth in localized microdontia is the maxillary lateral incisor, which may also be shaped like an inverted cone (a "peg lateral"). [3]
The teeth have a more curved distoincisal angle than the primary maxillary central incisor. [7] The tooth is longer cervicoincisally than it is mesiodistally. [ 7 ] The average length of the primary lateral incisor is 15.8 mm, with the average crown length being 5.6 mm and the root length average being 11.4 mm. [ 8 ]
