The mandibular lateral incisor is the tooth located distally (away from the midline of the face) from both mandibular central incisors of the mouth and mesially (toward the midline of the face) from both mandibular canines. As with all incisors, their function is for shearing or cutting food during mastication, commonly known as chewing. There are no cusps on the teeth. Instead, the surface area of the tooth used in eating is called an incisal ridge or incisal edge. Though relatively the same, there are some minor differences between the deciduous (baby) mandibular lateral incisor and that of the permanent mandibular lateral incisor.

  • The mandibular lateral incisor is the tooth located distally (away from the midline of the face) from both mandibular central incisors of the mouth and mesially (toward the midline of the face) from both mandibular canines. As with all incisors, their function is for shearing or cutting food during mastication, commonly known as chewing. There are no cusps on the teeth. Instead, the surface area of the tooth used in eating is called an incisal ridge or incisal edge. Though relatively the same, there are some minor differences between the deciduous (baby) mandibular lateral incisor and that of the permanent mandibular lateral incisor. In the universal system of notation, the deciduous mandibular lateral incisors are designated by a letter written in uppercase. The right deciduous mandibular lateral incisor is known as "Q", and the left one is known as "N". The international notation has a different system of notation. Thus, the right deciduous mandibular lateral incisor known as "82", and the left one is known as "72". In the universal system of notation, the permanent mandibular lateral incisors are designated by a number. The right permanent mandibular lateral incisor is known as "26", and the left one is known as "23". 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 lateral incisors would have the same number, "2", 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 lateral incisor is known as "42", and the left one is known as "32". (en)
  • Het volwassen, menselijk gebit telt vier laterale snijtanden, één in ieder kwadrant. Vanaf het midden van het gebit staan ze na de centrale snijtanden en vóór de hoektanden. Zoals de naam al zegt, dienen snijtanden om voedsel af te "snijden" tijdens het kauwen. Om deze functie te kunnen vervullen hebben de laterale snijtanden een relatief scherpe snijrand. De laterale snijtanden verschijnen in het wisselgebit meestal vlak na de centrale snijtanden, zo rond het 7e levensjaar. (nl)
  • L'incisivo laterale inferiore è il secondo dente dell'arcata dentaria. È leggermente più alto e grosso del centrale inferiore: è l'incisivo più lungo (23.5 mm, di cui 9.5 mm coronali e 14 radicolari), e più stretto (ha il diametro mesiodistale di 5.5 mm, quello vestibolo-linguale di 6.5). Il rapporto corona/radice indica che è un dente dotato di un forte ancoraggio, per poter sopportare le funzioni masticatorie svolte. Presenta numerose similitudini con l'incisivo centrale inferiore.
