Everything about The Mandibular Central Incisor totally explained
The
mandibular central incisor is the
tooth located on the
jaw, adjacent to the midline of the
face. It is mesial (toward the midline of the face) from both
mandibular lateral incisors. As with all
incisors, its function includes
shearing or cutting food during
mastication, commonly known as chewing. There are no
cusps on the tooth. Instead, the surface area of the tooth used in eating is called an incisal ridge or incisal edge. Though the two are similar, there are some minor differences between the
deciduous (baby) mandibular central incisor and that of the
permanent mandibular central incisor.
Notation
In the
universal system of notation, the deciduous mandibular central incisors are designated by a letter written in uppercase. The right deciduous mandibular central incisor is known as "P", and the left one is known as "O". The
international notation has a different system of notation. Thus, the right deciduous mandibular central incisor is known as "81", and the left one is known as "71".
In the universal system of notation, the permanent mandibular central incisors are designated by a number. The right permanent mandibular central incisor is known as "25", and the left one is known as "24". In the
Palmer notation, a number is used in conjunction with a symbol designating in which quadrant the tooth is found. For this tooth, the left and right central incisors would have the same number, "1", but the right one would have the symbol, "┐", over it, while the left one would have, "┌". The international notation has a different numbering system than the previous two, and the right permanent mandibular central incisor is known as "41", and the left one is known as "31".
Anatomy
The central incisors have
fossa on their lingual surfaces.
