The right deciduous maxillary canine is known as "C" and the left one "H". In international notation, the right deciduous maxillary canine is known as "53" and the left one "63". In the universal system of notation, the permanent maxillary canines are referred to by numbers. The right permanent maxillary canine is known as "6" and the left "11".
A distinctive feature is the nearly straight outline this tooth has compared to the maxillary canine which is slightly more bowed. As in the maxillary canine, the mesial incisal edge (or cusp ridge) is shorter than the distal side, however, the cusp is displaced slightly lingual relative to the cusp of the maxillary canine.
If it is a deciduous tooth that is being referred to, then a different number is used: upper right; upper left; lower left; lower right; The second and third numbers refer to the location of the tooth from front to back (or rostral to caudal). This starts at 01 and goes up to 11 for many species, depending on the total number of teeth.
An ectopic maxillary canine is a canine which is following abnormal path of eruption in the maxilla. An impacted tooth is one which is blocked from erupting by a physical barrier in the path of eruption.
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).
The removal of only the maxillary first premolars is the second likeliest option, in 14.5% of cases. [10] The practice of premolar extraction developed in the 1940s in the United States, and was initially greatly contested in the orthodontic field, due to the changes to the facial structure caused by the retraction of the arches.
Adult teeth are numbered 1 to 8, with primary teeth indicated by a letter A to E. 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]
The right deciduous mandibular canine is known as "R", and the left one is known as "M". The international notation has a different system of notation. Thus, the right deciduous mandibular canine is known as "83", and the left one is known as "73". In the universal system of notation, the permanent mandibular canines are designated by a number.
