OBJECTIVES The aim of this study was to analyze whether symmetry of left and right sides, gender, measuring method, and ethnicity have influences on width (W), length (L), and width to length ratio (W/L) of the maxillary central incisor (MCI) and provide

Traumatic intrusion of a maxillary central incisor
The Journal of the American Dental Association, 1969An intruded maxillary right central incisor was successfully removed from the nasal cavity of an auto accident victim. Removal was accomplished by use of a 25-gauge stainless steel wire loop.

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

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.

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

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.
