Management of a supernumerary tooth fused to a permanent maxillary Central Incisor.
Pediatric dentistry, 2010Co-Authors: Keiichiro Tsujino, Seikou ShintaniAbstract:A supernumerary tooth fused to a normal tooth often causes malocclusion and esthetic problems because of malformation and large crown. This requires treatment such as sectioning and extraction of the supernumerary tooth, modification of crown shape by contouring and restoration, or extraction. Moreover, endodontic treatment is often required as part of the procedure since pulp exposure occurs frequently during sectioning and modification of crown shape. The purpose of this paper was to report the case of a supernumerary tooth fused to the permanent maxillary left Central Incisor in a 9-year-old boy with unilateral (left side) cleft lip and palate and describe its management. After a thorough examination employing X-ray Computed Tomography (CT), the supernumerary tooth was separated from the Central Incisor at the fusion site and extracted under local anesthesia. No endodontic treatment was performed on the conserved Central Incisor. The Central Incisor's rotation was corrected by orthodontic treatment, followed by modification of the crown shape with composite resin. More than 4 years have passed since the first operative treatment, and the Central Incisor still remains vital. This case shows that a precise diagnosis is important in sectioning a fused tooth, and that CT-based data are very useful in planning treatment.

a supernumerary tooth fused to the facial surface of a maxillary permanent Central Incisor case report
Journal of Endodontics, 2000Co-Authors: Euiseong Kim, Yi Tai JouAbstract:A case of a supernumerary tooth fused to the facial surface of a maxillary permanent Central Incisor is reported. Root canal therapy on the maxillary Central Incisor was performed due to pulpal communication between the supernumerary tooth and the maxillary Central Incisor after removing the supernumerary tooth structure. The communication was sealed with mineral trioxide aggregate. The difference between fusion and gemination is discussed.

velocardiofacial syndrome with single Central Incisor
American Journal of Medical Genetics Part A, 2005Co-Authors: Snehlata Oberoi, Karin VargervikAbstract:Three siblings and their mother are reported who all had cytogenetically proven velocardiofacial syndrome (VCFS). One boy had normal dental and craniofacial findings, except for an increased cranial base angle. His sister had only one Central Incisor in the maxilla. One Central Incisor had also been missing in the primary dentition. She had no labial frenulum present. Cephalometry showed a small maxillary unit length indicating mild maxillary hypoplasia, an increased anterior face height, steep mandibular plane angle, retruded chin, and a large cranial base angle. Dental measurements showed retroclined lower Incisors and increased interincisal angle. A second sister had a cleft of the secondary palate. All permanent teeth were present with the exception of a missing Central Incisor in the lower jaw: the single lower Central Incisor was situated in the midline. Her cephalometry showed similar findings as in her sister. All three siblings required palate surgery for speech. Mother was not available for detailed dental and other oral investigations. A single maxillary Central Incisor has previously been reported in VCFS, but to our knowledge a single Central Incisor in the mandible has not been reported previously in this entity. © 2004 Wiley-Liss, Inc.

Solitary median maxillary Central Incisor syndrome and holoprosencephaly: a case report.
Pediatric dentistry, 2010Co-Authors: Elizabete Da Silva Viana, Paulo Floriani Kramer, Luciane Quadrado Closs, Giovana ScalcoAbstract:Solitary median maxillary Central Incisor syndrome (SMMCIS) is a rare anomaly that affects 1 in 50,000 live births. Of unknown etiology, SMMCIS is characterized by the presence of a single Central Incisor located on the maxillary midline and may be associated with developmental defects and systemic alterations. SMMCIS also is associated with short stature, mild forms of deviation in craniofacial morphology, and intellectual disability. The purposes of this paper were to: describe the clinical case of an 8-year-old boy with a permanent Central Incisor located at the midline in association with holoprosencephaly; and highlight the most important aspects related to diagnosis and treatment of solitary median maxillary Central Incisor syndrome.
