The teeth have a more curved distoincisal angle than the primary maxillary central incisor. In the deciduous maxillary central incisor, endodontic treatment is less frequent. From a facial aspect, maxillary canines are approximately one millimetre narrower than the central incisor. In the permanent maxillary central incisor, root canal treatment can be effective. Microdontia of a single tooth is more likely to occur in a maxillary lateral incisor. Studies from Asian populations report that the mandibular incisor is most commonly absent. This is done particularly if the mesiodens is positioned in the maxillary central incisor region. The mesial and distal contacts are more cervical than the central incisor. In males, the size of the maxillary central incisor is larger usually than in females. The lingual fossa is more concave than the central incisor. Crustacean mandibles may be equipped with special teeth (molar and incisor processes). It is directed forward against the lingual surfaces of the lower incisor teeth. Begin by assessing the incisor and molar relationship as described above. A canine is placed laterally to each lateral incisor. The trees are cut down using their strong incisor teeth.
