“…Two adjacent roots become fused by deposition of cementum between them after the resorption of interdental bone. The process is noted more frequently in the posterior and maxillary region 4 . The developmental pattern often involves a second molar tooth, in which its roots closely approximate the adjacent impacted third molar.…”

“…[5] The frequency of gemination or fusion ranges from 0.01% to 0.04% in the primary and 0.05% in the permanent dentition. [6] Gemination and fusion are generally asymptomatic. However, they can cause unesthetic appearance, space management problems, caries and periodontal disease, and impaction of adjacent teeth also.…”

“…[7] Geminated teeth have a characteristic appearance; the mesiodistal diameter of the clinical crown is larger than normal, and from the incisal edge to the apex of the root, a groove of unequal depth divides the tooth into two, usually unequal parts. [6] Supernumerary teeth are odontostomatologic anomaly characterized by the existence of an excessive number of teeth in relation to the normal dental formula. [8] The incidence in the mandibular anterior tooth area is about 0.01%.…”

Odontogenic anomalies are frequently observed by the pediatric dentist in their routine practice. These anomalies may pose a challenge to the dentist considering the magnitude of severity and the developing dentition of the child. Hyperdontia in the mandibular anterior region is a rare occurrence. We describe a case report of an 8-year-old child presenting with the concurrent occurrence of geminated tooth and a supplemental tooth in the mandibular anterior (incisor) region. Timely extraction of the geminated tooth was done to avoid tooth material arch length discrepancy. The surgical removal of the geminated teeth alleviated the mandibular anterior crowding in the patient, improved esthetics, and prevented the malocclusion due to the tooth material arch length discrepancy from progressing to a more severe form. The patient is presently being monitored every 3 months and will be evaluated for the orthodontic treatment once he attains the complete permanent dentition. It is very important for the dentists to have sound knowledge of the odontogenic anomalies seen in children. Early diagnosis and prompt treatment will help to achieve better occlusion, function, and esthetics in the patient and prevent malocclusion.

“…En ocasiones, la fusión se da entre un diente normal y un supernumerario, casos en los que es difícil establecer si es o no fusión, pues no habrá reducción de la fórmula dentaria [4]. Con frecuencia, la fusión se acompaña de surcos y fisuras adicionales muy profundos, que con facilidad son asiento de lesiones periodontales y endodónticas [1][2][3][4].…”

Resumen. La fusión se define como la unión parcial o completa de dos o más dientes durante su desarrollo; puede ocurrir entre dos dientes normales o entre un diente normal y un supernumerario. Esta anomalía puede ser unilateral o bilateral y puede comprometer cualquier dentición, aunque los dientes deciduos son los perjudicados con mayor frecuencia. Además de afectar la apariencia del paciente, puede causar alteración del espacio en los arcos dentarios, caries y comprometer las estructuras periodontales. En este artículo, se presenta el caso de un joven de 13 años que acude a consulta por repetidos eventos inflamatorios a nivel de la encía vestibular del 22. Estos episodios tienen su causa en la fusión del 22 con un diente supernumerario. Tras la evaluación radiográfica y la planificación adecuada, el diente supernumerario fue extraído, y se eliminó así el surco palatino que se formaba por la fusión de ambos dientes, causa principal de la lesión perioendodóntica que presentaba el paciente.Palabras clave: fusión dental, dentición permanente, supernumerario. Dental Fusion: Report on a Clinical CaseAbstract. Fusion is defined as the partial or complete union of two or more teeth during their development; it can occur between normal teeth or between a normal tooth and a supernumerary tooth. This anomaly can be unilateral or bilateral and can affect any teeth, although deciduous teeth are more frequently damaged. It can also affect the patient's appearance, cause changes in the dental arch space, lead to cavities and affect periodontal structures. This article presents the case of 13-year-old who came in for consultations due to repeated inflammatory events at the level of gum 22. These episodes stem from the fusion of tooth 22 with a supernumerary. After radiographic evaluation and adequate planning, the supernumerary tooth was extracted, and the palatal groove formed by the fusion of both teeth was eliminated, which had been the main cause of the patient's periodontal-endodontic lesion.Keywords: dental fusion, permanent teeth, supernumerary.
