ABSTRACT

ABSTRACT Dilated odontoma is a rare dental developmental anomaly that belongs to a class od dens in dente, being rarely described in the posterior region of the mandible. To be describe a dilated odontoma in the lower third molar region. this study had a qualitative, transversal, descriptive and documentar approach, of the case report type. Developed in the Integrated Health Clinics of a University in the Extreme South of Santa Catarina, in the Dentistry Service. This article presets a case of dilated odontoma in a 32-year-old male patient. The patient had pain and swelling in the left posterior region of the mandible. The Crown of this element was clinically within the normal range, however the radiographic examination showed barrel-shaped root alteration in element 38 and expansion of the buccal and lingual cortical bone. An incisional biopsy of the anomaly whas performed and sent to anatomopathological examination. According to the clinical, radiographic and anatomopathological characteristics, the diagnosis of dilated odontoma was reached. Due to the aberrant root anatomy, complete removal was chosen. The diagnosis of this abnormality depeds on the clinical, radiographic and anatomoathological characteristics and its therapy varies according to the invagination. In cases of deep invagination, extraction is indicated.


RESUMO O Odontoma Dilatado é uma rara anomalia de desenvolvimento dentário que pertence a uma classe de dens in dente, sendo raramente descrito na região posterior da mandíbula. O objetivo desse artigo foi descrever um Odontoma Dilatado na região de terceiro molar inferior. Materiais e métodos: este estudo teve abordagem qualitativa, transversal, descritiva e documental, do tipo relato de caso. Desenvolvido na Universidade do Extremo Sul Catarinense, no Serviço de Odontologia. Este artigo apresenta um caso de Odontoma Dilatado em um paciente do sexo masculino de 32 anos. O paciente apresentou dor e inchaço na região posterior esquerda da mandíbula. A coroa deste elemento encontrava-se, clinicamente, dentro dos padrões de normalidade, entretanto no exame radiográfico foi demonstrada a alteração radicular em forma de barril no elemento 38 e expansão de cortical óssea vestibular e lingual. Foi realizada a biópsia incisional da anomalia e enviado ao anatomopatológico. De acordo com as características clínicas, radiográficas e anatomopatológicas, chegou-se no diagnóstico de Odontoma Dilatado. Devido a anatomia aberrante optou-se pela remoção completa. O diagnóstico desta anormalidade é dependente das características clínicas, radiográficas e anatomopatológicas e sua terapêutica varia de acordo com a invaginação. Em casos de invaginação profunda a exodontia está indicada.

ABSTRACT

El diente invaginado (DI) es una alteración en el desarrollo del órgano dentario, el cual se produce a consecuencia de una invaginación del epitelio interno del órgano del esmalte, también conocido con otros nombres, entre ellos dens in dent. Tiene una serie de características clínicas, histológicas e imagenológicas debidamente descritas a través de la literatura. Su variante más extrema presenta una configuración muy compleja y, debido a la magnitud de la invaginación que presenta, se le denomina también odontoma dilatado, término que para algunos profesionales genera confusión.Este término ha sido mencionado como sinónimo tanto de DI como, en algún momento, de una nueva variante de odontomas, si bien existe una diferencia entre ambos tipos: uno es una anomalía del desarrollo y el otro, un crecimiento de aspecto hamartomatoso. Sin embargo, la literatura sigue utilizando ambos términos para definir al DI, por lo que es importante conocer el origen y tener claro que la controversia está basada en referencias históricas y de costumbre. (AU)


The invaginate tooth (IT) is an alteration in the development of the dental organ, which occurs as a consequence of invagination of the internal epithelium of the enamel organ. IT is also known as "dens in dente", among other denominations, and presents a series of clinical, histological and imaging characteristics. The most extreme variant of IT has a very complex configuration, and the magnitude of the intussusception has led to it also being called dilated odontoma, being a term that generates confusion in some professionals.While the term odontoma has been reported as a synonym for both IT as well as a new variant of odontomas, there is a difference betweene the two types: one is a developmental anomaly and the other is a growth with a hamartomatous appearance. However, the literature continues to use both terms to define IT, and thus, it is important to know the origin and be aware that the controversy is based on historical and customary references.

ABSTRACT

A fissura labiopalatina é uma malformação craniofacial que, como o próprio nome induz, envolve lábio, rebordo alveolar e palato. Pode ser acompanhada por algumas anomalias dentárias como o dens in dente, que necessita de avaliação radiográfica para auxílio em seu diagnóstico. Objetivo: Identificar nas radiografias periapicais o dens in dente em indivíduos com fissura labiopalatina, especificamente na região próxima à fissura. Metodologia: Foram avaliados 10 exames de radiografias periapicais de indivíduos com fissura labiopalatina, do arquivo de imagens digitais da Seção de Diagnóstico Bucal do Hospital de Reabilitação de Anomalias Craniofaciais (HRAC-USP, Bauru-SP, Brasil). Em uma primeira etapa, foram identificados os dens in dentes de cada indivíduo e posteriormente classificados de acordo com Oehlers (1957). Após essas etapas, todos os prontuários dos indivíduos foram avaliados quanto ao histórico de tratamento desses dentes. Conclusão: Na amostra radiográfica de indivíduos com fissura labiopalatina, encontrou-se a maior frequência do dens in dente no dente 12. De acordo com a classificação de Oehlers, 70% dos casos foram grau II, 30% grau I e o grau III não foi encontrado. Entre os lados das fissuras avaliadas com a presença de dens in den-te, 40 % estavam do lado direito, 40% bilateralmente e 20% do lado esquerdo. A radiografia periapical é fundamental para complementar o diagnóstico clínico. O tratamento pode variar de acordo com os níveis de comprometimento dessa anomalia dentária e depende da correta avaliação por parte do dentista.


The cleft lip and palate is a craniofacial malformation that, as its name induces, involves the lip, alveolar ridge, and palate. It may be accompanied by some dental anomalies such as dens in dente, which needs radiographic evaluation to aid in its diagnosis. Objective: To identify in periapical radiographs the dens in dente in individuals with cleft lip and palate, specifically in the region close to the cleft. Methods: Ten periapical radiographs of individuals with cleft lip and palate from the digital image file of the Oral Diagnosis Section at Hospital for Rehabilitation of Craniofacial Anomalies - University of São Paulo (Bauru, São Paulo, Brazil) were evaluated. In a first step, the dens in dente of individuals were identified. In a second step, they were classified according to the Oehlers (1957). After these phases, all the records of the individuals were evaluated regarding the treatment history of these teeth. Conclusion: In the radiographic sample of individuals with cleft lip and palate, the highest frequency of dens in dente was found in tooth 12. According to the Oehlers classification, 70% of the cases were type 2, 30% type 1, and type 3 was not found. Between the sides of the cleft evaluated for the presence of dens in dente, 40% were on the right side, 40% bilaterally, and 20% on the left side. Periapical radiography is essential to complement the clinical diagnosis. Treatment can vary according to the levels of impairment of this dental anomaly and depends on the correct evaluation by the dentist.

ABSTRACT

Introdução: dens in dente é uma anomalia rara de desenvolvimento, caracterizada pela invaginação dos tecidos dentários, podendo variar de um ligeiro aumento da fosseta do cíngulo a um profundo sulco, que pode se estender até o ápice dentário. Objetivo: o objetivo do presente artigo foi relatar um caso clínico e descrever as peculiaridades dos achados clínicos e radiográficos de um dens in dente Tipo III A, com ênfase na descrição de sua morfologia completamente atípica, além das dificuldades que foram encontradas no diagnóstico e durante o tratamento endodôntico. Caso clínico: o paciente compareceu ao ambulatório de uma clínica de Endodontia com queixa de dor e leve edema. Ao exame clínico e radiográfico, observou-se imagem sugestiva de dens in dente no elemento #22, sendo, então, proposto tratamento endodôntico convencional, com estudo tomográfico. Resultados: após 1 ano e 6 meses de acompanhamento, o paciente encontrava-se assintomático. Notou-se reparo satisfatório, com formação óssea, apesar da sobre-extensão do cone. Conclusão: foi possível perceber a importância da tomografia computadorizada de feixe cônico como auxiliar no diagnóstico e planejamento da conduta frente a casos de dens in dente, principalmente por aumentar as chances de sucesso, evitando a perda precoce de elementos dentários (AU).


Introduction: Dens invaginatus is a rare dental anomalycharacterized by invagination of dental tissues, which maybe from a slight increase in the pit of the cingulum to a deep groove that may extend to the tooth apex. This report describes clinical and radiographic findings and the morphology of a completely atypical and unique anomaly, and discusses the difficulties in the diagnosis and endodontic treatment of the root canal of teeth with this complex anatomy. Clinical case: Patient seen in the outpatient clinic of the Endodontic Service with a complaint of pain and mild edema. Clinical and radiographic examinations were suggestive of invagination itooth #22, and conservative endodontic treatment and CT scans were indicated. Results: Patient was asymptomatic and had no functional disorders at 18 months of follow-up. Repair and new bone formation were satisfactory, despite cone overextension. Conclusion: Cone-beam CT seems to be an important method of diagnosis and treatment planning in cases of dens invaginatus, especially because it increases the chances of treatment success and prevents the early loss of teeth (AU).

ABSTRACT

Los dientes pueden presentar trastornos originados por factores externos o hereditarios que afectan su forma. Dens in dente es una anomalía durante el desarrollo que resulta en la invaginación del esmalte y dentina, en la cara lingual o vestibular, que puede extenderse profundamente dentro de la raíz. El talón cuspídeo es caracterizado por la proyección de una cúspide accesoria en el cíngulo de los órganos dentarios anteriores y la superficie oclusal de los posteriores. Se presenta el caso de una niña de 7 años de edad, con dens in dente y talón cuspídeo en el incisivo central superior derecho que provoca interferencia oclusal prematura, sin sintomatología. Se realizó desgaste gradual del talón cuspídeo, con aplicación de fluoruro de sodio. El diagnóstico temprano de anomalías dentales en pacientes pediátricos es la clave para un tratamiento conservador y preventivo para el adecuado funcionamiento masticatorio y estético del paciente (AU)


Teeth may have disorders caused by external or hereditary factors that affect their shape. Dens invaginatus is an anomaly during development that results in invagination of the enamel and dentin, lingual or vestibular surface, which can extend deeply into the root. Talon cusp is characterized by the projection of an accessory cusp in the cingulate area in anterior and occlusal aspects of the posterior teeth. We present a case of a 7 year old girl with dens invaginatus and talon cusp on the maxillary central incisor that causes premature occlusal interference, without symptomatology. The treatment employed were gradual wear of cuspal talon with several applications of sodium fluoride. Early diagnosis in pediatric patients is the key to a conservative and preventive treatment for a proper masticatory and aesthetic functioning of the patient (AU)

ABSTRACT

Introduction: there are three types of dens in dente: Type I, minimal invagination confined to the crown of the tooth which does not extend beyond the amelocemental junction; Type II, invagination extends to the pulp chamber, but remains within the root canal with no communication with the periodontal ligament; and Type III, invagination extends to the root of the affected tooth, beyond the cementoenamel junction. The term dilated odontoma is used to describe the most severe variant of invagination (Type III), which is characterized by crown and/or root dilation of the affected tooth. Objective: describe a rare case of a dilated odontoma shaped dens in dente in a mesiodens and its imaging findings, diagnosed by cone beam computed tomography. Case presentation: a 14-year-old male patient was referred for radiographic examination of the mandible and maxilla to determine the cause of abnormal tooth eruption chronology. Two mesiodens were found on the maxilla. Due to the peculiar morphology of the mesiodens on the right side, cone beam computed tomography was performed. Multiplanar reconstructions revealed an oval structure on the eruption path of the upper right central incisor, in contact with its palatal surface. Coronal and sagittal reconstructions showed that invagination extended beyond the cementoenamel junction, without any additional apical/lateral formation. Conclusions: the final diagnosis was dilated odontoma shaped type II dens invaginatus in a mesiodens(AU)


Introducción: existen tres categorías de dens in dente: Tipo I, invaginación mínima confinada a la corona del diente y que no se extiende más allá de la unión amelo-cementaria; Tipo II, la invaginación se extiende a la cámara de la pulpa, pero permanece dentro del canal de la raíz, sin comunicación con el ligamento periodontal; y Tipo III, la invaginación se extiende a la raíz del diente afectado, más allá de la unión cemento-esmalte. El término odontoma dilatado se utiliza para describir la variante más grave de la invaginación (tipo III), que se caracteriza por la dilatación de la corona y/o laraíz del diente afectado. Objetivo: describir un caso raro de un dens in dente con formato de odontoma dilatado en un mesiodiente y sus hallazgos imagenológicos, diagnosticados mediante tomografía computarizada de haz cónico. Presentación del caso: paciente varón, 14 años de edad, fue enviado a un servicio de Radiología Odontológica con el fin de determinar la causa de anómala cronología de la erupción dental en maxilar superior y mandíbula. Dos mesiodientes fueron identificados en el maxilar superior. El mesiodiente del lado derecho llamó la atención debido a su peculiar morfología, por lo que se realizó la tomografía computarizada de haz cónico. Las reconstrucciones multiplanares revelaron una estructura ovalada ubicada en el trayecto de erupción del incisivo central superior derecho, en contacto con su superficie palatina. Reconstrucciones coronales y sagitales demostraron que era posible identificar la extensión de la invaginación más allá de la unión cemento-esmalte, sin constitución de forma apical/lateral accesoria. Conclusiones: el diagnóstico final fue dens invaginatus tipo II en forma de odontoma dilatado en un mesiodiente(AU)

ABSTRACT

Introdução: o defeito da morfologia nos dens invaginatus provoca falta de suprimento sanguíneo para a polpa e consequente necrose pulpar, culminando em lesão periapical. A intervenção com cirurgia paraendodôntica é comum nesses casos, em que o tratamento endodôntico conservador não é bem-sucedido, devido à complexa anatomia e inacessibilidade do tecido pulpar. Esse caso relata um tratamento endodôntico cirúrgico bem-sucedido, como evidenciado pela Tomogra a Computadorizada de Feixe Cônico (TCFC), em dens in dente tipo III com lesão periapical considerável. O tratamento endodôntico foi realizado em sessão única, seguido por apicectomia e retropreparo da cavidade, com auxílio de microscópio operatório e uso de pontas ultrassônicas, e obturação retrógrada com Agregado Trióxido Mineral (MTA). Osso bovino lio lizado e membrana de colágeno foram inseridos para preencher a cavidade. Após três anos de acompanhamento, radiogra as periapicais, TCFC e reconstrução 3D foram realizadas, apresentando resultados favoráveis no que diz respeito ao reparo da lesão.

ABSTRACT

Dens invaginatus is a developmental variation of a tooth resulting from an alteration in the normal growth pattern of the dental papilla. It is clinically characterized by a palatine furrow that can be limited to the coronal pulp or may extend to the radicular apex. The commonly affected tooth is maxillary lateral incisor. The occurrence of multiple dens invaginatus is extremely rare. Although a clinical examination may reveal a deep pit or fissure on the lingual surfaces of maxillary anterior teeth, the radiographic examination is the choice for diagnosis of dens invaginatus. Familiarity with the radiographic appearance of this anomaly is essential for the dental practitioner. The purpose of this paper is to present a clinical case of multiple dens invaginatus involving maxillary anterior teeth which was diagnosed during routine radiographic evaluation.

ABSTRACT

Dens in dente is a dental development malformation that involves more commonly the upper lateral incisors. Infection of the canal of these teeth can cause the formation of chronic periapical lesions. The present study aimed to describe an integrated approach between the endodontic therapy and surgical intervention in an upper lateral incisor with dens in dente type II. A female patient, 14 years old, sought for dental care complaining of left palatal and paranasal bulging. Clinical, radiological and histopathological findings suggested periradicular cyst. First, marsupialization was performed to reduce the size of the lesion and to favor its enucleation, with less risk of injuring the tooth and vital structures. After diagnosis of pulp necrosis and in attempt to reduce the infection via canal, we used the reciprocating instrumentation associated with irrigation with sodium hypochlorite, intracanal medication based on calcium hydroxide and filled with a thermoplastic filling. After a year of marsupialization, fistulectomy and complete enucleation of the lesion were performed. Proservation was performed 1, 3, 6 and 12 months following marsupialization. Six months after enucleation, we observed the periradicular repair and remission of symptoms. The extensive apical lesion associated with dens in dente type II can be treated with a combination of surgical and endodontic therapy.


Dens in dente é uma malformação no desenvolvimento dentário que envolve mais comumente os incisivos laterais superiores. A infecção do canal destes dentes podem causar a formação de lesões periapicais crônicas. O objetivo deste trabalho é descrever uma abordagem integrada entre a terapia endodôntica e a intervenção cirúrgica em um incisivo lateral superior com dens in dente tipo II. Paciente de 14 anos, gênero feminino, procurou atendimento odontológico com queixa de abaulamento em região palatina e paranasal esquerda. Os achados clínico, radiográfico e histopatológico sugeriram cisto perirradicular. Marsupialização foi realizada inicialmente para reduzir o tamanho da lesão, favorecer a enucleação da mesma, com menor risco de injuriar o dente e as estruturas vitais. Diagnosticado necrose pulpar e na tentativa de combater a infecção via canal, empregou-se a instrumentação reciprocante associada a irrigação com hipoclorito de sódio, medicação intracanal a base de hidróxido de cálcio e finalizou-se com uma obturação termoplastificada. Após um ano do procedimento de marsupialização realizou-se a fistulectomia e a completa enucleação da lesão. A proservação foi realizada 1, 3, 6 e 12 meses posteriormente a marsupialização. Seis meses após a enucleação observou-se a reparação perirradicular e remissão dos sintomas. A extensa lesão perirradicular associada ao dens in dente tipo II pode ser solucionada com uma combinação entre a intervenção cirúrgica e endodôntica.

ABSTRACT

Dens invaginatus is a developmental malformation that causes changes in the internal anatomy of the tooth. Fusion and twinning are terms commonly used to describe the clinical presentation of double teeth. The presence of double dens invaginatus is extremely rare. Therefore understanding the complex morphology, type and extension of dens invaginatus are very essential. To establish the diagnostic hypothesis based on a periapical radiograph is a challenge for all different dentistry specialties. With cone-beam computed tomography (CBCT), the diagnostic dilemma is minimized because of the accurate visualization of the anatomy. The visualization of three-dimensional structures is very helpful in the diagnosis of these complex anatomic variations as it favors precise definition of the problem and treatment planning. With this case report, we would like to highlight how CBCT helped in the evaluation and treatment planning of Double dens invaginatus of a fused supernumerary tooth and maxillary central incisor, which could not be done using the intraoral periapical method.

ABSTRACT

Dens invaginatus is one of the most frequent malformations in dental elements. It can affect all teeth, even primary and supernumerary ones. It consists of an invagination of the crown surface, which happens during odontogenesis and penetrates the interior of the pulp chamber of the dental elements involved. In some cases, it can reach the apical tooth area. The maxillary lateral incisor is the most common site of occurrence. Due to its complex and variable anatomy, the tooth may present pulp necrosis and open apex, making it difficult to salvage. Oehlers classified them into types I, II, and III according to their complexity. This article reviews the literature and describes the treatment of a maxillary central incisor with type II invagination. The invaginated structure in this case detached due to various instrumentations during the change of dressing phase, facilitating root canal filling. In conclusion, this case shows that many methods are capable of removing the invaginated area of a dens invaginatus type II.

.

O dente invaginado é uma das alterações de desenvolvimento que mais incide sobre os elementos dentários, podendo acometer qualquer dente existente na cavidade oral, inclusive decíduos e supranumerários. Consiste em uma invaginação da superfície da coroa, que ocorre na odontogênese, que penetra no interior da cavidade pulpar dos elementos dentários envolvidos, podendo chegar, em algumas situações, à região apical. O incisivo lateral superior permanente é o que apresenta maior envolvimento. Por apresentar uma anatomia complexa e variável, quando diagnosticado, o dente pode apresentar necrose pulpar e rizogênese incompleta, o que torna a sua manutenção muitas vezes de difícil solução. Em 1957, Oehlers classificou-os, conforme sua complexidade, em tipos I, II e III. Foi realizada uma revisão da literatura e descrito o tratamento de um incisivo medial superior com invaginação tipo II, cuja estrutura invaginada se desprendeu devido às várias instrumentações durante as trocas de curativo, o que facilitou sua obturação. Pudemos concluir com este caso a viabilidade, através de diversos métodos, da remoção da porção invaginada no tratamento de dentes invaginados tipo II.

ABSTRACT

Dens invaginatus is a developmental anomaly resulting from infolding of the surface of the tooth crown before calcification has occurred. While several mechanisms have been proposed for the cause of this phenomenon the exact etiology is not known. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. The nature of the problem may increase the risk of pulp disease and complicate any root canal treatment. Dens invaginatus has been seen very commonly in maxillary lateral incisors; however, reported cases in peg laterals are few. A case is reported here of unusual presentation of dens invaginatus in a peg lateral. The problems associated with treatment of such teeth are discussed.

ABSTRACT

La sinusitis odontogénica afecta la mucosa de los senos maxilares y puede ser causada por la evolución de una lesión en el diente con formación de pus periapical que avanza en el interior de la cavidad sinusal. Se presenta un caso de un paciente con dens in dente en el diente incisivo lateral superior derecho, que sufrió el proceso de caries evolucionando en la región periapical, contaminando la mucosa sinusal de este lado, lo que causó el dolor, abultamiento y el desplazamiento del diente. La cirugía se realizó a través de acceso de Caldwell-Luc para el curetaje de la lesión, lo que indica la presencia en el diagnóstico histopatológico la presencia de quiste abscedado y sinusitis. Después de 18 meses de control, se observó la regeneración ósea y el reposicionamiento alveolar espontáneo de los dientes implicados. Los autores advierten que cíngulos profundos y dens in dente son las enfermedades de los dientes que merecen atención para el diagnóstico y la prevención de los procesos de caries con el fin de evitar complicaciones mayores.


Odontogenic sinusitis affects mucous membrane of the maxillary sinus and can be caused by the evolution of a tooth injury with formation of periapical abscess that advances into the sinus cavity. We present a patient with dens in dente in the upper right lateral incisor tooth, which suffered carious process and periapical abscess, contaminating the sinus mucosa on this side, which caused pain, bulging and tooth displacement. Surgery was performed via a Caldwell-Luc access for curettage of the lesion, indicating the presence in the histopathological diagnosis of radicular cyst abscess and sinusitis. After 18 months of control, alveolar bone regeneration and spontaneous repositioning of teeth involved was observed. The authors warn that cingulum deep in dens in dente are diseases of the tooth that deserve attention for the diagnosis and prevention of carious processes in order to avoid further complications.

ABSTRACT

El diente invaginado es una malformación que resulta probablemente de un desdoblamientode la papila dental durante el desarrollo dentario. Los dens invaginatus son dientes clínicamentesignificativos, debido a la gran facilidad de afección de la pulpa. La profundidaddel defecto estructural varía de una leve ampliación del cíngulo a una invaginación quese extiende al ápice. El presente artículo relata el caso de una mujer de veintitrés años deedad, quien refiere una fístula de diez años de evolución en la mucosa en el fondo de sacoa la altura del diente lateral superior izquierdo (diente 22). Luego de la exploración clínica yradiográfica se diagnostica un dens in dente unilateral con necrosis pulpar y absceso apicalcrónico, para lo cual se realizó terapia de conductos y cirugía apical con éxito radiográficode dos años de evolución...


Invaginated tooth is a malformation likely resulting from a splitting of dental papilla duringtooth development. Dens invaginatus are clinically important teeth due to the easy affectionof the dental pulp. Invagination depth varies from a slight enlargement of the cingulum untoan extended invagination to the apex. This article reports the case of a female patient aged23, who referred fistula with ten years of evolution in tooth 22. The clinical and radiographicdiagnosis was dens in dent with necrosis and chronic suppurative periapical periodontitis.The root canal therapy and apical surgery were performed showing successfully radiographicevolution within a two-year follow-up period...

ABSTRACT

One of the most common dental anomalies is dens invaginatus. As the name indicates, it is an invagination of the coronary or root surface, bounded by enamel, which can be so profound as to simulate the appearance of a tooth inside another. Usually occurs in permanent maxillary lateral incisors, followed by maxillary central incisors, premolars, canines and less frequently molars. In this article we will describe the cone beam computed tomography features of a type III dens invaginatus.


Uma das anomalias dentárias mais comuns é o dens invaginatus. Assim como o nome indica, é uma invaginação da superfície coronária ou radicular, delimitada por esmalte, que pode ser tão profunda a ponto de simular a aparência de um dente dentro do outro. Normalmente ocorre em incisivos laterais superiores permanentes, incisivos centrais superiores, pré-molares, caninos e, menos frequentemente, molares. Neste artigo será descrito os achados por tomografia computadorizada de feixe cônico de um dens invaginatus tipo III.

ABSTRACT

Talon cusp is an uncommon anomaly, whose etiology may be disturbances in the morphodifferentiation stage. Dens in dente is also a rare anomaly that is challenging in clinic as it may cause pulp necrosis or periapical lesions due to the communication with the oral cavity. This article reports multiple talon cusps on permanent maxillary and mandibular incisors and molars in 3 siblings. A 9-year-old boy presented with structures like nodules, shaped as cylindrical cones with a sharp point or a raindrop with deep developmental fissures on the palatal aspect of the maxillary central incisors, lingual aspect of the mandibular central incisors and labial aspect of both mandibular first molars. The buccal surface of the maxillary right central incisor was also affected. Some of them exhibited dens in dente. His 15-year-old sister had prominent talon cusps on the palatal surface of maxillary central incisors and buccal surface of the mandibular first molars and mandibular left second molar. His 7-year-old brother had only one trace talon on the maxillary left central incisor. No syndrome was identified in the patients. In conclusion, genetic inheritance may be a causative factor in talon cusp.


Cúspide em garra (talon cusp) é uma anomalia incomum, cuja etiologia pode estar relacionada a distúrbios no estágio de morfo-diferenciação. Dens in dente é também uma anomalia rara que impõe desafios na prática clínica, uma vez que pode causar necrose pulpar ou lesões periapicais devido à comunicação com a cavidade oral. Este artigo relata múltiplos casos de cúspide em garra em incisivos e molares superiores e inferiores permanentes em 3 irmãos. Um menino de 9 anos apresentou-se com estruturas nodulares em formato de cone cilíndrico com uma ponta aguda ou de "gota de chuva", com fissuras de desenvolvimento profundas na face palatina dos incisivos centrais superiores, e face lingual dos incisivos centrais e vestibular de ambos os primeiros molares inferiores. A face vestibular do incisivo central superior esquerdo também foi afetada. Alguns dentes apresentavam dens in dente. Sua irmã de 15 anos apresentava cúspides em garra proeminentes na face palatina dos incisivos centrais superiores e face lingual dos primeiros molares inferiores e segundo molar inferior esquerdo. Seu irmão de 7 anos apresentava apenas uma cúspide em garra vestigial no incisivo central superior esquerdo. Nenhuma síndrome foi identificada nos pacientes. Conclui-se que a herança genética pode ser um fator causativo da cúspide em garra.
