          Abstract

          RESUMEN: El diente supernumerario de ubicación nasal es una patología de baja prevalencia en la población con diferentes formas y sintomatología clínica. Es importante establecer un diagnóstico respecto a sus características clínicas y radiológicas para realizar una planificación de tratamiento quirúrgica adecuada, con nula o escasas complicaciones post intervención. Presentación del caso: En el presente estudio se reporta el caso de un niño de 10 años de edad, sin antecedentes mórbidos, que recurre al servicio por presentar un diente supernumerario en la línea media hallado radiográficamente. El CBCT demuestra un mesiodens en el septum nasal, palatal inclinado e invertido, parcialmente erupcionado cubierto por mucosa nasal, con su corona en sentido a la cavidad nasal en relación a las fosas nasales. El diente fue extraído con anestesia general mediante un abordaje transoral a través de una vestibulotomía. El diente supernumerario nasal es una patología poco prevalente. Es importante conocer sus características clínicas y radiográficas ya que determinarán el tipo de abordaje a realizar. El grado de erupción, la distancia a la espina nasal anterior y su sintomatología asociada son fundamentales para determinar si el abordaje quirúrgico es intraoral o extraoral.

          ABSTRACT: The supernumerary tooth of nasal location is a pathology of low prevalence in the population with different forms and clinical symptoms. It is important to establish a diagnosis regarding its clinical and radiological characteristics in order to carry out adequate surgical treatment planning, with few or no post-intervention complications. Case presentation: This study reports the case of a 10-year-old boy, with no morbid history, who presented a supernumerary tooth, found radiographically in the midline. CBCT showed a mesiodens in the nasal septum, tilted and inverted palatal, partially erupted covered by nasal mucosa, with its crown facing the nasal cavity in relation to the nostrils. The tooth was extracted under general anesthesia using a transoral approach through a vestibulotomy. The nasal supernumerary tooth is a rare pathology. It is important to know its clinical and radiographic characteristics since they will determine the type of approach to be used. The degree of eruption, the distance to the anterior nasal spine and its associated symptoms are essential to determine whether the surgical approach is intraoral or extraoral.

          Supernumerary teeth: review of the literature and a survey of 152 cases.

          A review of the literature relating to supernumerary teeth is presented along with a survey of 152 cases. The study population consisted of 152 children who visited the department of Paediatric Dentistry at the Jordan University Hospital. Patients ranged in age from 5 to 15 years. Supernumeraries were detected by clinical examination and radiographs. Males were affected more than females with a sex ratio of 2.2 : 1. Seventy-seven percent of the patients had one supernumerary tooth, 18.4% had double teeth, and 4.6% had three or more supernumeraries. Ninety percent of the supernumerary teeth occurred in the premaxilla, of which 92.8% were in the central incisor region and of these latter 25% were located in the midline. The other 10.4% of the supernumeraries were located in the premolar, canine, molar, and lower central incisor regions. Two cases were of non-syndrome supernumerary teeth. Seventy-five percent of the supernumeraries were conical, 83.1% were in the normal vertical position and 26.5% were erupted. Conical-shaped supernumerary teeth had a significantly higher rate of eruption compared to the tuberculate type.

            Prevalence, etiology, diagnosis, treatment and complications of supernumerary teeth

            The aim of this article was to review the literature on supernumerary teeth, analyzing their prevalence, etiology, diagnosis, treatment and possible complications. An electronic search was made in the Pubmed-Medline database up to January 2014 using the key search terms “multiple supernumerary teeth” (n=279), “prevalence supernumerary teeth” (n=361), and “supernumerary teeth” (n=2412). In addition to the articles initially identified, others were included in the review proceeding from a manual search and from any references considered of relevance. Supernumerary teeth are those that exceed the normal dental formula. They are more common in men, more common in the upper maxilla, and more prevalent in permanent dentition. Complications associated with supernumerary teeth include dental impaction, delayed eruption, ectopic eruption, overcrowding, spacing anomalies and the formation of follicular cysts. The treatment of supernumerary teeth depends on their type, position, and possible complications, detected clinically and radiographically. No clear consensus exists as to the best time to extract unerupted supernumerary teeth. Key words:Hyperdoncia, supernumerary teeth, impacted teeth, treatment, permanent teeth, deciduous teeth.

              Supernumerary Teeth: Review of the Literature with Recent Updates

              A supernumerary tooth (ST) is defined as any tooth or odontogenic structure that is formed from tooth germ in excess of usual number for any given region of the dental arch. They may be single or multiple and unilateral or bilateral in distribution and can occur in any region of the dental arch. These may occur in primary and permanent dentition. Supernumerary teeth are more frequent in males. They are classified based on form, morphology, location, and occurrence. Several hypotheses have been proposed to explain the occurrence of ST. However, combination of environmental and genetic factors has been proposed. Supernumerary teeth cause a range of complications like crowding, displacement, dilacerations, cyst formation, and so forth. Early identification and appropriate treatment plan should minimize the potential complications caused by ST.
