ABSTRACT

The calcifying epithelial odontogenic tumor is a rare benign neoplasm that accounts for approximately 1% of all odontogenic tumors. Most of the cases occur in the posterior mandible, and a few involve the maxilla. Despite their relatively indolent biological behavior, tumors in the maxilla tend to grow fast. We report the case of a 33-year-old female patient exhibiting swelling in the right maxilla. An isodense area associated with an impacted supernumerary tooth was found on imaging examination. The histopathologic diagnosis was a calcifying epithelial odontogenic tumor. The treatment of choice was surgical removal of the lesion and associated dental elements. The patient has been followed up for 11 months and shows no signs of recurrence. Besides describing this case, we reviewed the literature on the association of calcifying epithelial odontogenic tumors with supernumerary teeth and found two case reports addressing this subject.

ABSTRACT

ABSTRACT Introduction: Supernumerary teeth in cases of cleft lip and palate do not result from the division of normal germs before the formation of hard tissue. Deciduous and permanent teeth odontogenesis begins after the face has formed, either with or without the cleft. Discussion: The most acceptable hypothesis to enable understanding of the presence of supernumerary teeth on one or both sides of the cleft palate is hyperactivity of the dental lamina in its walls. This hyperactivity, with the formation of more tooth germs, must be attributed to mediators and genes related to tooth formation, under strong influence of local epigenetic factors, whose developmental environment was affected by the presence of the cleft. Conclusion: The current concepts of embryology no longer support the fusion of embryonic processes for the formation of the face, but rather the leveling of the grooves between them. All human teeth have a dual embryonic origin, as they are composed of ectoderm and mesenchyme/ectomesenchyme, but this does not make it easy for them to be duplicated to form supernumerary teeth.


RESUMO Introdução: Os dentes extranumerários nas fissuras labiopalatinas não são resultado da divisão dos germes normais antes da formação do tecido duro. A odontogênese dos decíduos e permanentes inicia-se depois de formada a face, com ou sem fissuras. Discussão: A hipótese mais plausível para compreender a presença dos dentes extranumerários em um ou nos dois lados da fissura labiopalatina é a hiperatividade da lâmina dentária em suas paredes. Essa hiperatividade, com formação de mais germes dentários, deve ser atribuída aos mediadores e genes relacionados à formação dos dentes, sob forte influência de fatores epigenéticos locais, cujo ambiente de desenvolvimento foi afetado pela presença da fissura. Conclusão: Os conceitos atuais da embriologia não fundamentam mais a fusão de processos embrionários para a formação da face, e sim o nivelamento dos sulcos entre eles. Todos os dentes humanos têm uma dupla origem embrionária, pois se compõem de ectoderma e mesênquima/ectomesênquima, mas isso não facilita sua duplicação para formar dentes extranumerários.

ABSTRACT

Introducción: Los dientes supernumerarios son anomalías donde hay un aumento de la fórmula dental normal. Ocasionalmente provocan complicaciones, como la formación de un quiste dentígero. Por lo infrecuente del hallazgo, y más aún del reporte de esta asociación, se realizó la presentación del caso. Objetivo: Describir el manejo de un supernumerario distomolar en rama mandibular asociado a un quiste dentígero, enfatizando en la importancia de los estudios imaginológicos preoperatorios y el abordaje quirúrgico endobucal. Presentación del caso: Paciente femenina de 34 años, que se extrajo los terceros molares en la adolescencia, y que 3 meses atrás presentó una celulitis facial por la que se le realizó una ortopantomografía, y se detectó un molar en la rama mandibular. Al examen bucal se encontró ligera expansión de la tabla vestibular de rama mandibular izquierda. Se constató en la ortopantomografía la presencia de una estructura dentaria del grupo molar asociada a área radiolúcida, lo que se corroboró en una tomografía. Se planificó la exéresis de ambos mediante abordaje endobucal bajo anestesia general. No se presentaron complicaciones. La paciente fue egresada a las 24 horas y fue seguida evolutivamente por consulta externa durante 6 meses. El diagnóstico histopatológico indicó la presencia de un quiste. Conclusiones: La detección de un diente supernumerio distomolar en rama mandibular asociado a quiste dentígero es una situación clínica infrecuente que permite explotar los beneficios de estudios imaginológicos digitales y crear un plan de tratamiento que culmine en la exéresis exitosa por vía endobucal, sin complicaciones(AU)


Introduction: Supernumerary teeth are anomalies in which there is an increase of the normal dental formula. They occasionally cause complications, such as the formation of a dentigerous cyst. Because of the unusual finding, and even more because of the report of this association, a case presentation is carried out. Objective: To describe the management of a supernumerary distomolar in the mandibular ramus associated with a dentigerous cyst, making emphasis on the importance of the preoperative imaging studies and the endo-buccal surgery approach. Case presentation: 34 years old female patient from whom the third molars were removed during adolescence, who presented facial cellulitis 3 months before the molars removal, which was a reason to perform an orthopantomography. Then, a molar in the mandibular ramus was detected. During oral examination, a light vestibular table expansion in the left mandibular ramus was found. The presence of a dental structure from the molar group which was associated with a radiolucent area was confirmed by orthopantomography, and was also confirmed by CT-scan. Exeresis of both molars under general anesthesia was planned, with an endo-buccal approach. There were no complications. The patient was discharged 24 hours later, and was treated in the outpatient consulting room for 6 months. Histopathological diagnosis revealed the presence of a cyst(AU) Conclusions: The finding of a supernumerary distomolar tooth in the mandibular ramus associated with a dentigerous cyst is an infrequent clinical situation that allows to make good use of the benefits of digital imaging studies, and implement a treatment plan that ends in a successful exeresis via an endo-buccal route, without any complications(AU)

ABSTRACT

Dente supranumerário é definido como um distúrbio de desenvolvimento caracterizado pela presença de um ou mais elementos dentários fora do número considerado normal de uma arcada. A ocorrência dos supranumerários pode ocasionar uma variedade de complicações, como por exemplo, apinhamento de dentes permanentes, erupção retardada e/ou ectópica, rotação dentária, formação de diastema, desenvolvimento de lesões císticas, reabsorção de dentes adjacentes. Na maioria das vezes o diagnóstico da presença desse elemento é realizado por exame clínico e radiográfico de rotina. O objetivo do presente trabalho foi relatar um caso clínico de retenção prolongada de um dente decíduo e erupção retardada de um dente permanente em decorrência da presença de um elemento supranumerário diagnosticado apenas aos 12 anos de idade. Após a identificação do elemento supranumerário e análise de exames radiográficos complementares,foi realizada cirurgia para remoção dos elementos decíduo e supranumerário, bem como acompanhamento por três meses do processo eruptivo do elemento impactado,um segundo pré-molar inferior direito o qual se posicionou favoravelmente na arcada dentária. Concluiu-se que a detecção em momento oportuno e a remoção de elementos supranumerários, também respeitadas à necessidade e oportunidade cirúrgica, são importantes para evitar danos futuros à oclusão dos pacientes, devendo-se dar importância ao acompanhamento e evolução clínica do caso.


Supernumerary teeth is defined as a developmental disorder characterized by the presence of one or more dental elements out of a number considered normal arch. The occurrence of supernumerary can cause a variety of complications, such as crowding of the permanent teeth,delayed and / or ectopically erupting, tooth rotation, diastema training, development of cysticlesions, resorption of adjacent teeth. In most cases the diagnosis of the presence of this elementis made by clinical examination and routine radiographic. The aim of this study was to reporta case of prolonged retention of a primary tooth eruption and delayed a permanent tooth dueto the presence of a supernumerary element diagnosed only 12 years old. After identifying the supernumerary element and analysis of complementary radiographs, it was carried out surgeryto remove the elements deciduous and supernumerary and monitoring for 3 months of the eruptive process impacted element, a premolar law that favorably-positioned in the dental arch.It was concluded that the timely detection and removal of supernumerary elements also respected the need and surgical opportunity, are important to prevent future damage to the occlusion of patients, should be given importance to the monitoring and clinical outcome.

ABSTRACT

INTRODUCTION: Orthodontic-surgical treatment was performed in patient with skeletal Class III malocclusion due to exceeding mandibular growth. Patient also presented upper and lower dental protrusion, overjet of -3.0 mm, overbite of -1.0 mm, congenital absence of tooth #22, teeth #13 and supernumerary impaction, tooth #12 with conoid shape and partly erupted in supraversion, prolonged retention of tooth #53, tendency to vertical growth of the face and facial asymmetry. The discrepancy on the upper arch was -2.0 mm and -5.0 mm on the lower arch. METHODS: The pre-surgical orthodontic treatment was performed with extractions of the teeth #35 and #45. On the upper arch, teeth #53, #12 and supernumerary were extracted to accomplish the traction of the impacted canine. The spaces of the lower extractions were closed with mesialization of posterior segment. After aligning and leveling the teeth, extractions spaces closure and correct positioning of teeth on the bone bases, the correct intercuspation of the dental arch, with molars and canines in Angle's Class I, coincident midline, normal overjet and overbite and ideal torques, were evaluated through study models. The patient was submitted to orthognathic surgery and then the post-surgical orthodontic treatment was finished. RESULTS: The Class III malocclusion was treated establishing occlusal and facial normal standards.


INTRODUÇÃO: o presente trabalho apresenta um tratamento ortodôntico-cirúrgico realizado em paciente portadora de má oclusão de Classe III esquelética com crescimento mandibular, protrusão dentária superior e inferior, trespasse horizontal de -3,0mm, trespasse vertical de -1,0mm, ausência congênita do dente 22, dentes 13 e supranumerários inclusos, dente 12 com forma conoide e parcialmente irrompido em supraversão, retenção prolongada do dente 53, tendência ao crescimento vertical da face e assimetria facial. A discrepância na arcada superior era de -2,0mm, e na inferior era de -5,0mm. MÉTODOS: o tratamento ortodôntico pré-cirúrgico foi realizado com extrações dos dentes 35 e 45. Na arcada superior foram extraídos os dentes 53, 12 e supranumerário, para efetuar o tracionamento do canino incluso. Os espaços das extrações inferiores foram fechados com mesialização do segmento posterior. Após o alinhamento e nivelamento dos dentes, foram avaliados por meio de modelos de estudo o fechamento dos espaços das extrações e o posicionamento correto dos dentes nas bases ósseas, a intercuspidação correta das arcadas dentárias, com molares e caninos em Classe I de Angle, linhas medianas coincidentes, trespasse horizontal e trespasse vertical normais e torques ideais. A paciente foi encaminhada para realização de cirurgia ortognática e, em seguida, o tratamento ortodôntico pós-cirúrgico foi finalizado. RESULTADOS: a má oclusão de Classe III foi corrigida, estabelecendo padrões oclusais e faciais normais.

ABSTRACT

Although developmental anomalies of tooth number are quite common in permanent dentition, concomitant occurrence of hypohyperdontia is a very rare mixed numeric anomalous condition of teeth. Very few cases of this condition have been reported in the English literature. Here we report such a rare case noted in a 26 year-old male dental graduate with no other associated systemic condition or syndrome.

ABSTRACT

PURPOSE: Dental fusion is defined as the union of two dental germs at some stage of their development. The aim of this article is to report the endodontic treatment of two clinical cases of dental fusion. CASE DESCRIPTION: In the first case, the patient was referred by an orthodontist for endodontic treatment of tooth 12, which was fused to 13. Surgical separation and later replacement of the involved elements in the dental arch was indicated. In the second case, the patient sought dental attendance due to spontaneous pain. In the radiographic exam, gemination in tooth 11 and fusion of 21 with a supernumerary tooth was observed. The fused teeth were endodontically treated, and patients were referred to other dental specialties to reestablish esthetics and function. CONCLUSION: The dentist must be able to diagnose, differentiate and treat these dental anomalies adequately, with the goal of maintaining patients' oral health.


OBJETO: Fusão dental é definida como sendo a união de dois germes dentais em algum momento do estágio de desenvolvimento. O objetivo desse artigo foi descrever o tratamento endodôntico de dois casos de fusão dental. DESCRIÇÃO DO CASO: No primeiro caso clínico, o paciente foi orientado pelo ortodontista a realizar tratamento endodôntico do dente 12, o qual estava fusionado ao dente 13. Foi realizada a separação cirúrgica dos elementos dentais e posterior reposicionamento no arco dental. No segundo caso clínico, o paciente procurou atendimento relatando dor espontânea na região anterior superior. Por meio do exame radiográfico, foi observado geminação do dente 11 e fusão do dente 21 com dente extranumerário. Em ambos os casos os dentes fusionados foram tratados endodônticamente e os pacientes encaminhados para restabelecimento da estética e função. CONCLUSÃO: O cirurgião dentista deve ter habilidade de diagnosticar, diferenciar e tratar adequadamente as anomalias dentárias, objetivando a manutenção da saúde oral dos pacientes.

ABSTRACT

Objective: To present an uncommon case of numeric abnormalities in a non-syndromic patient.Discussion: Dental numeric abnormalities in development of the permanent dentition are quite common;however, combined occurrence of hypodontia and hyperdontia is a rare phenomenon, especiallyin a non-syndromic situation. This paper describes a 28-year-old non-syndromic man with missing mandibularlateral incisors and an erupted mandibular mesiodens. This is only the third case, to the best ofour knowledge, with the two anomalies manifesting in the anterior region of the mandible.


Objetivo: Apresentar um caso incomum de anomalias numéricas num caso de paciente não sindrômico. Discussão:Anomalias dentárias numéricas no desenvolvimento da dentição permanente são comuns; entretanto, a ocorrênciacombinada de hipo e hiperdontia é um fenômeno raro, especialmente em situações não sindrômicas. Este artigo descreve o caso de um paciente masculino não sindrômico apresentando ausência de incisivos laterais mandibularese um mesiodens mandibular erupcionado. Esse é o único caso, pelo melhor de nosso conhecimento, com as duasanomalias manifestando-se simultaneamente na região anterior da mandíbula.

ABSTRACT

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch and the talon cusp is a rare dental developmental anomaly seen on the lingual surface of anterior teeth. This paper presents a rare clinical case of development of talon cusp in a mesiodens with multiple lobes, which interfered with both occlusion and appearance of an 11-year-old patient. During clinical interview, the patient reported difficulty on mastication. Clinical and radiographic examination revealed that a supernumerary tooth with completely formed root was causing an occlusal interference. The supernumerary tooth was diagnosed as multi-lobed mesiodens associated with a palatal talon cusp. The treatment plan consisted in the extraction of the supernumerary tooth followed by orthodontic treatment for diastema closure and tooth alignment.


Mesiodens é um dente supranumerário mais comumente visto no arco maxilar na linha média, e a cúspide em garra (talon cusp) é uma anomalia dental de desenvolvimento rara que ocorre na face lingual de dentes anteriores. Este artigo apresenta um caso clínico raro de desenvolvimento de uma cúspide em garra em um mesiodens multilobulado que causava interferência tanto na oclusão quanto na aparência de um paciente de 11 anos de idade. Durante a entrevista clínica, o paciente relatou dificuldade na mastigação. Exame clínico e radiográfico revelou que um dente supranumerário com raiz completamente formada estava causando interferência oclusal. O dente supranumerário foi diagnosticado como sendo um mesiodens multilobulado associado a uma cúspide em garra palatina. O plano tratamento consistiu na extração do dente supranumerário seguida de tratamento ortodôntico para fechamento de diastema e alinhamento dos dentes.

ABSTRACT

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.

ABSTRACT

Concomitant hypodontia and hyperdontia is a rare condition of unknown etiology. One such case of occurring in identical twins in mixed dentition is presented and discussed. A sibling, especially a twin of an affected patient, should be suspected of having a similar problem, even if he or she is asymptomatic. Genetic factors probably play an important etiological role in the co-occurence of partial anodontia and supernumerary teeth.

ABSTRACT

Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between reduced enamel epithelium and the tooth crown of an unerupted tooth. When observed with erupted and complete dentition the diagnosis is a surprise; as about 95% of dentigerous cysts involve the permanent dentition and only 5% are associated with supernumerary teeth. The usual age of clinical presentation of dentigerous cyst due to supernumerary tooth is during the first four decades. Mesiodens is a supernumerary tooth situated between the maxillary central incisors. More frequently the mesiodens occurs unilaterally, but it may also be bilateral, while three or more supernumerary teeth in the median region of the palate are more rarely found. We report a rare case of dentigerous cyst in association with multiple mesiodens in a 14-year-old female patient.

ABSTRACT

The management of two unusual cases of dens invaginatus and talon cusp is presented. The first concerns talon cusp in maxillary primary and permanent lateral incisors, a supplemental tooth with dens invaginatus hampering eruption of the permanent incisors. The other present with bizarre crown morphology of a lateral incisor with talon cusp, dens invaginatus and a palatal accessory cusp-like structure. Early diagnosis and management are important to avoid complications.

ABSTRACT

Supernumerary teeth which occur both in the primary and the permanent dentition are seen more frequently in the permanent dentition causing a variety of pathological disturbances. Presented herewith is a case report of a patient with a mesiodens which had caused flaring of the maxillary central incisors and impeded normal eruption of the maxillary lateral incisors. Extraction of the mesiodens was carried out; subsequently followed by the space closure utilizing simple fixed orthodontic therapy.

ABSTRACT

O cisto dentígero, também conhecido como folicular, é o segundo tipo mais comum entre os cistos odontogênicos. Na mandíbula, sua localização mais freqüente é no terceiro molar, enquanto que, na maxila, os dentes caninos são mais envolvidos. O cisto dentígero é capaz de tornar-se o mais agressivo dos cistos odontogênicos, estando sempre associado à coroa de dentes retidos ou impactados. Seu crescimento contínuo pode provocar expansão das corticais ósseas, com conseqüente assimetria facial; deslocamento de dentes e reabsorções radiculares externas em dentes vizinhos. Embora seja mais freqüente, em ordem decrescente, nos terceiros molares inferiores, caninos superiores, terceiros molares superiores, e pré-molares inferiores, é possível que esteja associado a dentes supranumerários. Portanto, não deve ser afastada a hipótese diagnóstica de cisto dentígero, pelo simples fato de o paciente apresentar todos elementos dentários na arcada, uma vez que estas lesões císticas podem envolver dentes supranumerários. Os autores relatam, no presente trabalho, um caso clínico de cisto dentígero originado de um dente supranumerário, com suas características clínicas e radiográficas. A importância do exame histopatológico para a confirmação do diagnóstico é ressaltada

ABSTRACT

Mesiodens is a supernumerary tooth with a cone shaped crown and a short root situated between the maxillary central incisors. Supernumerary teeth occur as isolated dental findings or as part of a syndrome. They are frequently discovered when a normal tooth is either delayed in its eruption or displaced often resulting in arch length inadequacy. An early diagnosis allows early intervention, more favourable prognosis and minimal complications. Presented here are two cases of unusual bilateral mesiodens.

ABSTRACT

Dentes ectópicos foram descritos em uma grande variedade de locais, sendo sua ocorrência em seios paranasais extremamente rara. Relatamos um caso no qual uma paciente com quadro clínico de sinuosi crônica foi submetida a tomografia computadorizada de seios da face que revelou a existência de uma pansinusite e uma estrutura de densidade óssea em regiäo de células etmoidais posteriores a esquerda. Esta paciente foi submetida a cirurgia tendo sido detectada durante o ato cirúrgico, uma estrutura de consistência óssea de aspecto morfológico semelhante a um dente. A descriçäo anatomopatológica da massa encontrada foi de dente ectópico de estrutura habitual. O diagnóstico clínico radiológico é muitas vezes inconclusivo, porém é importante, devido ao aumento de morbidade associada com tal patologia
