Codes, names, and usual number of roots: (see chart of teeth at Universal Numbering System) 11 21 51 61 maxillary central incisor 1; 41 31 81 71 mandibular central incisor 1; 12 22 52 62 maxillary lateral incisor 1; 42 32 82 72 mandibular lateral incisor 1; 13 23 53 63 maxillary canine 1; 43 33 83 73 mandibular canine 1; 14 24 maxillary first ...
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".
Hence the left and right maxillary central incisor would have the same number, "1", but the right one would have the symbol, "┘", underneath it, while the left one would have, "└". [ citation needed ]
In 1891, Victor Haderup devised a variant of eight tooth quadrant system in which plus (+) and minus (-) were used to differentiate between upper and lower quadrants, and between right and left quadrants (e.g., +1 = upper right central incisor; 1- = lower left central incisor). Primary teeth were numbered as upper right (05+ to 01+), lower left ...
- Non-working condyle: This is the side to which the mandible is moving away from (e.g. if the mandible moves laterally to the right, the left condyle is the non-working side condyle) The maximum lateral movement of the mandible to the left or right side is approximately 10-12mm [2]
Over time, the cyst decreases in size and bone regenerates in the cavity space. Marsupialization could also be performed, which involves suturing the edges of the gingiva surrounding the cyst to remain open. The cyst then drains its contents and heal without being prematurely closed. The end result is the same as the cystostomy, bone regeneration.

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] Peg laterals typically occur on both sides, [2] and have short roots. [2] Inheritance may be involved, [2] and the frequency of microdontia in the upper laterals is just under 1%. [1]
