Dental gemination in the inferior canine in both dentition: case report / Geminación dental en canino inferior en ambas denticiones: reporte de caso

Geminate teeth are anomalies arising from the attempt of the division of a only one germ, characterized by invagination and resulting in incomplete formation of two teeth. In general, it presents two crowns, totally or partially separated, with one root and one root canal. Female patient, 8 years old, Asian descent (Chinese), attended a private clinic (Odemira Dental Clinic) in Odemira, Portugal, for a routine consult. At intraoral clinical examination differentiated coronary anatomy, of the tooth 83 was found, with the presence of a bifid crown in which there was a central groove that came from the cemento-enamel junction. The radiographic exam revealed the presence of only one wide root canal, and two separate pulp cavities, each one corresponding to a portion of the bifid crown. There was also, its permanent successor, with similar radiographic features In our case we could observe the alteration in the inferior canine of both dentition with a bifid crown and radiographically only one root as well as only one root canal with two pulp cavities.

Los dientes geminados son anomalías derivadas del intento de división de un solo germen, que se caracteriza por la invaginación y provoca la formación incompleta de dos dientes. En general, el diente presenta dos coronas, total o parcialmente separadas, con una sola raíz y un conducto radicular. Paciente mujer de 8 años de edad, ascendencia asiática (China), asistió a una clínica privada (Clínica Dental Odemira) en Odemira, Portugal, por una consulta de rutina. Al examen clínico intraoral se encontró una diferencia anatómica coronaria, del diente 8.3, con la presencia de una corona bífida en la cual había un surco central desde la unión cemento-esmalte. El examen radiográfico reveló la presencia de un solo conducto radicular, ancho, y dos cavidades pulpares separadas, cada una correspondiente a una parte de la corona bífida. Además se encontró su sucesor permanente, con similares características radiológicas. En nuestro caso, pudimos observar la alteración en el canino inferior de la dentición, tanto con una corona bífida y una sola raíz radiográficamente, así como un solo canal de la raíz con dos cavidades pulpares.

Kabuki make-up (Niikawa-Kuroki) syndrome: dental and craniofacial findings in a Brazilian child

This article reports the case of a Brazilian child diagnosed with Kabuki make-up syndrome (KMS), addressing the clinical features observed, with emphasis on the disease-specific oral and craniofacial manifestations. The patient had the distinctive KMS craniofacial appearance, mild delayed mental development, fingers with prominent fingertip pads and visual deficit. The dental findings included fusion of the left mandibular incisors (central and lateral), gemination of the right mandibular central incisor and congenital agenesis of the right mandibular lateral incisor, in the primary dentition, as well as absence of both permanent mandibular lateral incisors. Fusion and gemination have not been previously referred to as typical dental features in KMS. The detection of unique dental findings, such as missing teeth and dental anomalies of form in the primary dentition by means of clinical and radiographic examinations, might consist of a helpful diagnosis parameter in identifying children who may have milder forms of Kabuki syndrome.

Este artigo relata o caso de uma criança portadora da Síndrome de Kabuqui e descreve as características clínicas observadas, com ênfase nas manifestações craniofaciais e intrabucais. O paciente apresentava características craniofaciais clássicas da síndrome, deficiência mental leve, déficit visual e atraso no desenvolvimento dental. Os achados intrabucais incluíam a fusão dos incisivos inferiores do lado esquerdo (central e lateral), geminação do incisivo central inferior direito e agenesia do incisivo lateral inferior direito na dentição decídua bem como ausência dos incisivos laterais inferiores permanentes. Fusão e geminação ainda não foram descritas em pacientes com a síndrome. Assim, a detecção de achados dentais como agenesias e anomalias de forma na dentição decídua, por meio de exames clínicos e radiográficos, são importantes para auxíliar no diagnóstico de crianças com uma forma moderada da Síndrome de Kabuqui.

Fused supernumeraries in deciduous dentition: a case report.

The occurrence of supernumerary teeth and fusion of two teeth is not a very rare findings but the fusion of two supernumeraries especially in primary is very rare. Reported here, is a case of three supernumerary teeth present in the same region, out of which two of them were fused with each other. Since the interference with the normal eruption of the permanent successor was anticipated, the fused supernumeraries were extracted.

Connation of permanent incisors: a report of two cases.

Presented here are two uncommon cases of connation of permanent incisors. The term connation is being used in this paper instead of fusion, gemination etc., as it ideally describes the anomaly. Various treatment modalities have also been recommended for such cases.

Fusion of primary incisors--a report of six cases.

Six cases of asymptomatic dental twinning anomalies in the primary dentition are reported in 4205 school children. A clinical and radiographic presentation of the cases of fusion of primary incisor teeth is illustrated. This clinical entity has been found to appear with varied clinical and radiographic appearances. An association of fusion of primary incisors with the number of succedaneous teeth was seen.

Tratamento endodôntico de um dente fusionado / Endodontic management of a fused tooth: case report

Bilaterally fused primary mandibular incisors--a case report.

Fusion of teeth results from abnormal events in the embryologic development of teeth. In most cases the clinical and radiological findings allow only a presumptive diagnosis to be established since the specific terminology described refers to the etiology of the process, which often cannot be established. An unusual case of bilateral fusion in primary mandibular incisor region in a four-year-old boy is reported.
