ABSTRACT
Epithelial root sheath plays a key role in guiding the development of tooth root. Any problems during its growth can lead to various forms of defects or abnormalities in the development of tooth root. Radicular invaginatus may occur when the epithelial root sheath excessively proliferates and infolds into the dental papilla. In terms of tissue origin and occurrence mechanism, the radicular dens invaginatus is similar to the coronal invaginatus which is led by the proliferation and infolding of enamel organ. However, there had been no consensus on the term and classification of this type of developmental abnormality as well as the relationships among the dens invaginatus, the radicular invaginatus and the palatogingival groove. From the role of epithelial root sheath during root development, the manifestations of root developmental defects and abnormalities will be analyzed. The pathogeny, classification, clinical characteristics of the radicular invaginatus, the relationship with the dens invaginatus and the impact on treatment were specially focused on.

Dens invaginatus is a rare developmental anomaly of the teeth that is caused by the infolding of enamel organs or the penetration of their proliferations into dental papillae before calcification has occurred. The presence of double dens invaginatus is extremely rare. This paper describes the use of cone beam computed tomography in the evaluation of a maxillary lateral incisor with double dens invaginatus and periapical periodontitis. The tooth was treated through microscopic root canal therapy. The tooth was free of clinical symptoms, and the periradicular lesion narrowed during the follow-up period of 1 year.

El diente evaginado (DE) es una anomalía del desa-rrollo que se define como un tubérculo o protube-rancia que se extiende desde la superficie oclusal del diente afectado. La fractura o desgaste de esta pro-longación, internamente compuesta por tejido pul-par, puede causar diversas enfermedades pulpares, como pulpitis, necrosis pulpar e incluso dar lugar a una periodontitis apical. En el presente caso clíni-co se muestra el tratamiento de DE en un segundo premolar superior izquierdo que presentaba como diagnóstico necrosis pulpar y absceso alveolar cró-nico. El tratamiento consistió en realizar la terapia endodóntica con técnica de apexificación empleando BiodentineTM (AU)
Dens evaginatus (DE) is a dental developmental defect defined as a tubercle or protuberance that extends from the occlusal surface of the affected tooth. Fracture or wear of this extension, internally composed of pulp tissue, can cause diverse pulp diseases, such as pulpitis, pulpal necrosis and it can even induce apical periodontitis.The following clinical case shows the treatment of DE in a maxillary left second premolar diagnosed with pulp necrosis and chronic alveolar abscess. The treatment of choice was endodontic therapy using BiodentineTM (AU)

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. (AU)

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.

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).

We report a clinical case of type Ⅲ dens invaginatus with endodontic-periodontal lesion in a maxillary lateral incisor. The palatal radicular anomaly predisposed the tooth to periodontal lesions. The caries along the palatal groove caused tooth pulp necrosis and periapical lesions. By means of microscopic root canal therapy, apical surgery, and guided periodontal tissue regeneration, the apical and periodontal infection were controlled, and the affected tooth was retained.

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)

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)

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.

Talon’s cusp is an anomalous structure that projects palatally from the cingulum areas of maxillary or mandibular anterior teeth. This dental anomaly may pose several pathological, functional and esthetic problems. Talon cusps usually affect a single tooth, but may rarely affect an entire sextant. Such multiple talon cusps may not always occur in association with a syndrome. Furthermore, they may exhibit a genetic pattern of inheritance. This article emphasizes rare occurrence of such nonsyndromic multiple talon cusps in two siblings.

Dens invaginatus is a well-known malformation of teeth, which probably results from an invagination of enamel organ into dental papilla during tooth development. The endodontic treatment of invaginated teeth may be challenging due to difficulties in accessing the root canals and also due to complex variations of internal morphology. This article presents the endodontic management and follow-up in a rare case of right mandibular second premolar with Oehlers' type III dens invaginatus. The result of cold pulp testing was positive for this tooth but it was associated to a sinus tract and periapical lesion. Herein, it is described the root canal therapy of this tooth combined with periapical surgery, emphasizing the importance of proper diagnosis and planning by using cone beam computed tomography (CBCT). This case report presents the proper periapical healing 6 months after the combination of nonsurgical and surgical treatments. It also shows that CBCT is an important auxiliary examination to avoid errors in diagnosis and subsequent treatment of dental anomalies.
Dens invaginatus é uma malformação dentária já bem reconhecida, que provavelmente resulta de uma invaginação do órgão do esmalte para dentro da papila dentária durante o desenvolvimento do dente em questão. O tratamento endodôntico de dentes invaginados pode ser um desafio devido às dificuldades de acesso aos canais radiculares e também devido à complexidade da morfologia interna. Este artigo apresenta o manejo endodôntico e o acompanhamento de um caso raro de segundo pré-molar inferior direito com dens invaginatus Tipo III de Oehlers. O resultado do teste de sensibilidade pulpar ao frio foi positivo para este dente, mas o mesmo estava associado a uma fístula e lesão periapical. Relata-se o tratamento de canal deste dente associado à cirurgia periapical, enfatizando a importância de um correto diagnóstico e plano de tratamento, utilizando a tomografia computadorizada de feixe cônico (TCFC). Este relato de caso mostra reparo periapical adequado 6 meses após a combinação dos tratamentos não-cirúrgico e cirúrgico. Mostra também que a TCFC é um importante exame auxiliar para evitar erros no diagnóstico e posterior tratamento de anomalias dentárias.
