Beware the solitary maxillary median central incisor

Journal of Orthodontics, 2008
The incidence of a solitary maxillary median central incisor (SMMCI) tooth in the general population is low, in either the primary or secondary dentition. The most common cause of a missing maxillary central incisor is trauma, or more rarely hypodontia.

A dual-rooted maxillary central incisor

Journal of Endodontics, 1984
It is a well-known truism that maxillary central incisors are single-rooted, single-canaled teeth (1). Ingle and Beveridge (2) state that maxillary central incisors have one canal 100% of the time. The following case did not, however, adhere to the truism or statistics of 100%. It manifests both two roots and two canals.

Traumatized maxillary central incisor

Journal of Endodontics, 1975
Summary A maxillary right central incisor in a 19-year-old boy had a very large root canal with an open apical foramen and a periapical lesion.

Assessment of Maxillary Central Incisor Crown Form

The International Journal of Periodontics and Restorative Dentistry, 2013
Incisor crown form is thought to be associated with different periodontal features, and it is hypothesized that there are measures of the maxillary central incisor that can be used to characterize its form. The aim of this study was to assess maxillary central incisor crown dimensions to determine morphologic groups.

Complete intrusion of maxillary permanent central incisors

Journal of Clinical Pediatric Dentistry, 2003
Orthodontic extrusion can be time consuming and has a long retention period, making cooperation a critical factor. On the other hand, it has also been shown that surgical techniques may be useful to extrude and save the root. Surgical methods need at least 3 week for root stabilization in new position.
