Atypical extraction of maxillary central incisors
American Journal of Orthodontics and Dentofacial Orthopedics, 2010This case report describes a Class I crowded malocclusion with an ankylosed maxillary central incisor that was in infraocclusion and labially displaced. The patient had wide maxillary teeth, and the option of extracting the maxillary central incisors followed by space closure, with lateral incisors substituting for the central incisors, was chosen.

Traumatized maxillary central incisor
Journal of Endodontics, 1975Summary 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. There was a small radiopaque substance, 2 mm in diameter, adjacent to the apex of this tooth. Histologic examination of the fragment showed that it was a portion of the root tip.

A dual-rooted maxillary central incisor
Journal of Endodontics, 1984It 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.

Single central maxillary incisor and holoprosencephaly
American Journal of Medical Genetics, 1987AbstractA holoprosencephalic child was born to a mother with a single central maxillary incisor. The infant had a median cleft lip, a flat nose with a single nostril, hypotelorism, and normal chromosomes. The head was brachycephalic and small, and computed tomography (CT) of the brain showed semilobar holoprosencephaly. The mother had mild hypotelorism

The occurrence of a single median maxillary central incisor (SMMCI) is a very rare condition and might be a sign of a more severe midline defect, which could be a mild degree of holoprosencephaly. Absence of the internasal and partial absence of the intermaxillary suture has been observed in a fetus with holoprosencephaly. The purpose of this study was

The management of the dilacerated impacted maxillary central incisor
Dental Update, 2016The clinical problem of how best to manage a dilacerated, impacted maxillary central incisor will only be encountered rarely. The treatment aim should be to achieve results that are indistinguishable from normal appearance in a way that is appropriate for the patient.

The primary Maxillary Central Incisor in the Solitary Median Maxillary Central Incisor syndrome.
European journal of paediatric dentistry, 2012Solitary Median Maxillary Central Incisor (SMMCI) is a developmental anomaly in the permanent dentition with one single central incisor in the maxilla, positioned exactly in the midline. This condition has been associated with extra- and intraoral malformations in the frontonasal segment of the cranium and face. It is not known whether the centrally

Root canal system of the maxillary central incisor
Journal of Endodontics, 1990To better assess the efficacy of mechanical preparation of root canals, transparent specimens of 510 extracted maxillary central incisors were investigated for thickness and curvature of the root canal, condition of any accessory canals, and location of the apical foramen.

Assessment of Maxillary Central Incisor Crown Form
The International Journal of Periodontics and Restorative Dentistry, 2013Incisor 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.
