, 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".
