Múltiples Dientes Supernumerarios en Paciente Pediátrico No Sindrómico. Una Revisión de la Literatura y Presentación de Caso Clínico / Multiple Supernumerary Teeth In A Non-Syndromic Pediatric Patient. A Review Of The Literature and Presentation of a Clinical Case

Aquellos casos en que se excede la fórmula dentaria normal primaria de 20 dientes o definitiva de 32 dientes se conocen como dientes supernumerarios o hiperodoncia. Los supernumerarios se pueden presentar de manera única o múltiple y de forma heteromórfica o eumórfica. El supernumerario más prevalente es el mesiodens, se da más en hombres, en dentición permanente y en el maxilar. Su etiología no está confirmada, pero puede deberse a una hiperactividad de la lámina dental. El tratamiento varía de acuerdo a cada paciente según si está afectando a la dentición normal o no y el desarrollo que tengan las estructuras dentarias. El siguiente reporte de caso habla de un paciente de 6 años, no sindrómico, en donde se presentó con un mesiodens erupcionado y se encontraron más supernumerarios gracias a la radiografía complementaria.

Those cases in which the primary normal dental formula of 20 teeth or the final one of 32 teeth is exceeded are known as supernumerary teeth or hyperdontia. The supernumeraries can be presented in a single or multiple way and in a heteromorphic or eumorphic way. The most prevalent supernumerary is the mesiodens, it occurs more in men, in the permanent dentition and in the maxilla. Its etiology is not confirmed, but it may be due to hyperactivity of the dental lamina. The treatment varies according to each patient depending on whether it is affecting the normal dentition or not and the development of the dental structures. The following case report talks about a 6-year-old, non- syndromic patient, who presented with an erupted mesiodens and more supernumeraries were found thanks to the complementary radiography.

Tubercular intranasal mesiodens is oro-facial digital syndrome

Ectopic eruption of teeth has been reported in mandibular condyle, coronoid process, orbit, maxillary antrum, palate, nasal septum and chin. But an erupted supernumerary nasal tooth is rare. Although asymptomatic in some, a nasal tooth has the potential to cause epistaxis, septal perforation, rhinorrhea and several other complications. It is still rare for a nasal tooth to be associated with Oro-facial-digital syndrome which is a genetic malformation involving oral, facial and digital structures syndrome include hypertrophic frenula, lingual hamaartomas, ankyloglossia, dental caries, anomalous anterior teeth, enamel hypoplasia, supernumerary teeth and missing teeth. Presented is a case of an erupted tubercular mesiodens in the nasal cavity of a boy aged ten years. To the best of our knowledge, this is the first reported case of a nasal tooth in a child with oro-facial-digital syndrome. Children born with structural anomalies of the face, oral cavity and digits should be thoroughly evaluated to rule out the possibility of syndromes. Moreover, a multidisciplinary approach is required to render the best treatment of the patient. Also, a nasal tooth should be considered a possibility amongst undiagnosed nasal masses

Multiple dental anomalies and aggressive periodontitis: A coincidence or an association.

Aggressive periodontitis (AgP) comprises a group of rare, often severe, rapidly progressive forms of periodontitis mostly characterized by an early age of clinical manifestation and a distinctive tendency for cases to aggregate in families. Abnormal dental morphology and position have been associated with severe periodontal diseases. The purpose of this paper is to report a case of multiple dental anomalies associated with AgP. This paper reports a case of unusual association of multiple dental anomalies to AgP. Clinical findings and history led to the diagnosis of localized AgP, and radiologically. It was associated with multiple dental anomalies, especially supernumerary roots. Thus, the present case represents a very interesting demonstration of AgP association with supernumerary roots and the nature of this association merits further investigations.

Cementum analysis in cleidocranial dysostosis.

OBJECTIVE: Cleidocranial dysostosis (CCD) is a skeletal disorder associated with dental anomalies such as failure or delayed eruption of permanent teeth and multiple impacted supernumerary or permanent teeth. Absence of cellular cementum at the root apex is presumed to be one of the factors for failure or delayed eruption. The aim of this study was to analyze the root cementum of supernumerary(S) and permanent teeth (P) of a CCD patient and to compare the findings with those of normal individuals with special emphasis on delayed eruption. MATERIALS AND METHODS: Ground sections of 12 extracted teeth (9S + 3P) of a CCD patient and 12 teeth of normal individuals (5S + 7P) were taken for the study. The sections were longitudinal and 50 microm thick. Root characteristics were recorded with the aid of a light microscope. RESULTS: The absence of apical cellular cementum, increased root resorption and increased percentage of the gap type of cemento-enamel (C-E) junctions were significant findings noted both in the supernumerary and permanent teeth of the CCD patient. CONCLUSION: The presumption of cellular cementum is essential for tooth eruption is not supported by the findings of the present study. Delayed exception could be attributed to various other factors like mechanical obstruction, reduced serum alkaline phosphatase levels etc. Also, the significance of the increased percentage of the gap type of C-E junctions and its role in tooth eruption has to be further evaluated.

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.

Molariform supernumerary tooth--a case report.

The occurrence of a single supernumerary tooth in the upper canine region a rare condition is reported. The crown resembles a molar tooth, thus suggesting a molariform supernumerary tooth.

Estudo sobre prevalência de dentes supranumerários numa populaçäo infantil na faixa etária de 6 a 12 anos com vistas à prevençäo de futuras maloclusöes / A study about supernumerary teeth prevalence in a child population with ages ranging from 6 to 12 years with the objective of preventing future malocclusions

Os dentes supranumerários säo descritos como dentes formados em maior número que os de série normal. Embora raros na dentadura decídua, aparecem com certa freqüência na dentiçäo mista e dentadura permanente, principalmente na regiäo ântero-superior da cavidade bucal. O objetivo deste estudo foi avaliar a prevalência destes elementos dentários, sua localizaçäo e possíveis alteraçöes patológicas derivados de sua presença, numa populaçäo infantil de 6 a 12 anos de idade, na Clínica de Graduaçäo da Faculdade de Odontologia de Piracicaba, Universidade Estadual de Campinas (UNICAMP)

Inverted mesiodens--a case report.

A nine and a half years old female school child was examined in a during routine dental examination. The patient had swelling over maxillary midline area just near the labial frenum. Both the central incisors were in position. Radiographic examination revealed presence of an inverted supernumerary tooth between the roots of the central incisors. Surgical extraction of the supernumerary was planned. A unique case of inverted (upside down) mesiodens is presented.
