RESUMO
Introducción: Los dientes supernumerarios constituyen una anomalía de número en la cual se excede la cantidad normal de piezas dentales. La geminación es una anomalía de forma que se caracteriza por la presencia de una corona bífida y una raíz común. Los dientes supernumerarios geminados son de rara aparición; indicar exámenes imagenológicos son importantes para determinar sus características y su relación con las estructuras vecinas. Objetivo: Presentar el caso clínico de un paciente con un diente supernumerario geminado. Caso clínico: Paciente de sexo masculino de 23 años de edad, acude a la consulta odontológica por presentar una elevación del lado izquierdo en el paladar, sin molestias. En el examen clínico se observa un aumento de volumen de mucosa palatina de piezas dentales 24 y 25. Los exámenes de imagen fueron realizados y se diagnosticó un diente supernumerario geminado retenido, se realizó tratamiento quirúrgico y el paciente evolucionó favorablemente. Conclusión: Los dientes supernumerarios geminados son poco frecuentes, una oportuna y correcta evaluación imagenológica, le permitirá al clínico realizar un adecuado diagnóstico y tratamiento(AU)
Introduction: Supernumerary teeth constitute an anomaly of number where the normal number of teeth is exceeded and gemination is an anomaly of shape characterized by the presence of a bifid crown, a common root. Geminate supernumerary teeth are of rare occurrence; indicating imaging examinations are important to determine their characteristics and their relationship with neighboring structures. Objective: To present the clinical case of a patient with a geminate supernumerary tooth. Clinical case: A 23-year-old male patient came to the dental office due to an elevation on the left side of the palate, without discomfort. In the clinical examination, an increase in the volume of the palatal mucosa of teeth 24 and 25 was observed. The imaging examinations were performed and a retained geminated supernumerary tooth was diagnosed, surgical treatment was performed and the patient progressed favorably. Conclusion: Geminate supernumerary teeth are rare; a timely and correct imaging evaluation will allow the clinician to make an adequate diagnosis and treatment(AU)

ABSTRACT The diagnosis and treatment of supernumerary teeth pose a challenge for dental clinicians and pediatric dentists. These teeth are asymptomatic and may cause the delayed eruption of the permanent dentition, altered bone growth and ectopic positioning. This paper reports a case of the surgical removal of supernumerary teeth in the anterior region of the maxilla of a child under general anesthesia in a hospital setting. A six-year-old female patient visited a private dental office in the city of Garanhuns, Brazil, accompanied by her mother, who reported a tooth with a "strange shape" in the anterior region as the main complaint and also reported that her daughter's first dental experience was negative. The clinical examination and imaging tests were performed under general anesthesia to confirm the diagnosis. In view of the patient's dental and behavioral history, surgical treatment was performed in a hospital setting and assisted by a multidisciplinary team. Care in the hospital setting was found to be feasible, providing greater comfort for uncooperative patients.
RESUMO Os dentes supranumerários representam um desafio para clínicos e odontopediatras quanto ao diagnóstico e tratamento. São assintomáticos, podendo gerar atraso na dentição permanente, alteração do crescimento ósseo e posicionamento ectópico. Assim, o presente trabalho teve como objetivo apresentar um relato de caso de remoção cirúrgica de dentes supranumerários na região anterior da maxila de um paciente infantil, em ambiente hospitalar sob anestesia geral. O paciente do sexo feminino, 6 anos, compareceu ao consultório apresentando como queixa a presença de um dente "estranho" na região anterior. Foram realizados o exame clínico e exames de imagem com a confirmação do diagnóstico de dentes supranumerários na região do incisivo central superior direito (11) e do incisivo central superior esquerdo (21). Tendo em vista o histórico odontológico e comportamental da paciente, optou-se em realizar o tratamento cirúrgico em ambiente hospitalar, auxiliado por equipe multidisciplinar. Dessa forma, ao final dos procedimentos foi verificado que o atendimento em ambiente hospitalar é viável para maior conforto do paciente não colaborador.
RESUMO
Abstract Cleidocranial dysplasia (CCD) is a skeletal disorder affecting cranial sutures, teeth, and clavicles, and is associated with the RUNX2 mutations. Although numerous patients have been described, a direct genotype-phenotype correlation for RUNX2 has been difficult to establish. Further cases must be studied to understand the clinical and genetic spectra of CCD. Objectives To characterize detailed phenotypes and identify variants causing CCD in five unrelated patients and their family members. Methodology Clinical and radiographic examinations were performed. Genetic variants were identified by exome and Sanger sequencing, data were analyzed by bioinformatics tools. Results Three cases were sporadic and two were familial. Exome sequencing successfully detected the heterozygous pathogenic RUNX2 variants in all affected individuals. Three were novel, comprising a frameshift c.739delA (p.(Ser247Valfs*)) in exon 6 (Patient-1), a nonsense c.901C>T (p.(Gln301*)) in exon 7 (Patient-2 and affected mother), and a nonsense c.1081C>T (p.(Gln361*)) in exon 8 (Patient-3). Two previously reported variants were missense: the c.673C>T (p.(Arg225Trp)) (Patient-4) and c.674G>A (p.(Arg225Gln)) (Patient-5) in exon 5 within the Runt homology domain. Patient-1, Patient-2, and Patient-4 with permanent dentition had thirty, nineteen, and twenty unerupted teeth, respectively; whereas Patient-3 and Patient-5, with deciduous dentition, had normally developed teeth. All patients exhibited typical CCD features, but the following uncommon/unreported phenotypes were observed: left fourth ray brachymetatarsia (Patient-1), normal clavicles (Patient-2 and affected mother), phalangeal malformations (Patient-3), and normal primary dentition (Patient-3, Patient-5). Conclusions The study shows that exome sequencing is effective to detect mutation across ethnics. The two p.Arg225 variants confirm that the Runt homology domain is vital for RUNX2 function. Here, we report a new CCD feature, unilateral brachymetatarsia, and three novel truncating variants, expanding the phenotypic and genotypic spectra of RUNX2 , as well as show that the CCD patients can have normal deciduous teeth, but must be monitored for permanent teeth anomalies.
RESUMO
RESUMEN Introducción: el tratamiento de dientes incluidos es uno de los problemas que se presentan en pacientes que requieren tratamiento de Ortodoncia. Presentación del caso: paciente de 10 años, con antecedentes de salud que acude a la consulta de Ortodoncia por presentar alteraciones en el brote de los incisivos superiores. Al examen bucal presenta dentición mixta con ausencia clínica de 21. En rayos X panorámico se observa 21 retenido asociado a diente supernumerario. El tratamiento de elección fue la combinación ortodóncica quirúrgica. Conclusiones: con un manejo interdisciplinario adecuado, mediante técnicas innovadoras y económicas, se logró llevar el diente al arco dentario, corregir líneas medias, restablecer la estética y la función en un caso poco común por su localización en los dientes centrales, que, al ser más visibles, puede afectar estética y psicológicamente a los niños en su interacción con el medio social.
ABSTRACT Introduction: the treatment of impacted teeth is one of the problems that arise in patients requiring orthodontic treatment. Case Report: a 10-year-and-5-month patient having a health history comes to the orthodontic office for presenting alterations in the eruption of the upper incisors. On the oral examination she presented mixed dentition with clinical absence of 21 and the panoramic x-rays showed the retention of the 21 which is associated with a supernumerary tooth. The treatment of choice was the surgical orthodontic combination. Conclusions: with an appropriate interdisciplinary management, leaving the traditional way, and by means of innovative along with economic techniques, it was possible to bring the tooth to the dental arch, correct midlines, reestablish esthetics and function in an uncommon case due to its location in the central teeth, which, being more visible, can affect esthetically and psychologically the children in their interaction with the social environment.
RESUMO
ABSTRACT Developmental disorders of human dentition may result in various abnormalities according to etiologic agents and the developmental period involved. The size, shape and number of teeth may be affected. Dental abnormalities can occur singly or in multiples in an individual and may or may not be associated with syndromes. Complementary radiographic examinations are valuable for diagnosis, especially in lesions that are asymptomatic and detected only through examination. The present study is intended to report a case of an incidental finding in panoramic radiography of an odontoma, a supernumerary tooth and permanent tooth agenesis in the same non-syndromic individual. According to the literature, the association of hypodontia and hyperdontia (called concomitant hypo-hyperdontia) is most common. The association of hyperdontia and odontoma is uncommon but still reported. However, regarding the association of hypodontia and odontoma no reports were found, as well as the association of the three pathologies.
RESUMO Os distúrbios de desenvolvimento da dentição humana podem resultar em diferentes anomalias dependendo do agente etiológico e do período do desenvolvimento acometido. O tamanho, a forma e o número dos dentes, dentre outros, podem ser afetados. Podem ocorrer isoladamente ou em conjunto num mesmo indivíduo, bem como estarem ou não associados a síndromes. Os exames radiográficos complementares são valiosos para o diagnóstico, sobretudo quando as lesões são assintomáticas e detectadas incidentalmente no exame. O presente trabalho relata o caso de achado incidental, em radiografia panorâmica, de odontoma, dente supranumerário e agenesia de dente permanente num mesmo indivíduo não sindrômico. Segundo relatos da literatura, a associação de hipodontia e hiperdontia, denominada hipo-hiperdontia concomitante, é a mais comumente encontrada. A associação de hiperdontia e odontoma é incomum, mas ainda é relatada. No entanto, a respeito da associação de hipodontia e odontoma não foram encontrados relatos, bem como da associação das três patologias.
RESUMO
RESUMEN Fundamento: Los odontomas son entidades odontogénicas benignas mixtas, compuestas por una mezcla de células odontogénicas epiteliales y mesenquimatosas diferenciadas, las mismas pueden ser compuestas y complejas. Los hallazgos radiográficos de estos tumores en posiciones supernumerarias son raras menores al 1 %. Objetivo: Describir el caso clínico de un odontoma complejo infrecuente. Presentación de caso: Paciente femenina de 18 años con un trauma facial, que durante el diagnóstico imagenológico se le encontró una imagen anterosuperior de aspecto tumoral en posición supernumeraria, por lo que se decidió realizar la exéresis quirúrgica de la lesión después de finalizado el tratamiento del trauma. El diagnóstico clínico histopatológico fue de un odontoma complejo. Conclusiones: Se recomienda realizar las vistas imagenológicas tipo ortopantomografías o panorámicas a cada paciente que vaya a ser operado de cirugía bucal a fin de poder detectar de forma precoz cualquier alteración en la anatomía y de esta manera estudiar tanto el comportamiento de los odontomas como de otras lesiones intraóseas, lo que puede garantizar un tratamiento temprano y con ello un mejor pronóstico para el paciente.
ABSTRACT Background: Odontomas are mixed benign odontogenic entities, composed of a mixture of odontogenic epithelial and differentiated mesenchymal cells, they can be compound and complex. Radiographic findings of these tumors in supernumerary positions are rare, less than 1%. Objective: To describe the clinical case of a non-frequent complex odontoma. Case report: 18-year-old female patient with facial trauma, during the imaging diagnosis it was found an anterosuperior tumor image in supernumerary position, thus decided to perform the surgical excision of the lesion after the trauma treatment. The histopathological clinical diagnosis was a complex odontoma. Conclusions: It is recommended to perform standard panoramic radiograph imaging for each patient to be operated on oral surgery to detect any early anatomy alteration, so this way to study both, the behavior of odontomas as well as other intraosseous lesions, which can guarantee an early treatment and a better prognosis for the patient.

Dimension, number and shape alterations are frequently observed dental anomalies. Objective: The aim of this study was to map the frequency, the preferred location and the most prevalent types of supernumerary teeth, in the studied population. In addition, to assess the interference that supernumerary teeth may cause in the ectopic eruption of the normal dental series teeth. Methods: This is an observational retrospective study. Data collection was performed by evaluation of dental records of patients treated in an orthodontic clinic. Patients' radiographs, photographs and gypsum dental models were analyzed and data recorded in protocol files, by previously trained undergraduate and postgraduate students. Records from 1984 to 2019 were evaluated, and evaluation lasted two months. Data were stored in Microsoft Office Excel (version 2016) for descriptive analysis. Results: From the 920 patients' records analyzed, 2.7% presented at least one supernumerary tooth, with preferred location on the anterior maxillary area and mandibular parapremolar area. The most prevalent type was the supplemental tooth, with normal eruption orientation and normal alveolar location. Conclusion: The supernumerary teeth of the studied population showed little interference in the ectopic eruption of the normal dental series. Most of the supernumerary teeth were impacted, and, approximately one third of the supernumerary teeth showed deviated eruptions.

Abstract Objective: To investigate the prevalence and characteristics of supernumerary teeth among patients attending the students' dental clinics at the Faculty of Dentistry of the Arab American University, Jenin, Palestine. Material and Methods: This is a descriptive, cross-sectional, retrospective study of 1970 digital panoramic radiographs of patients, age ranging between 12 and 50 years. The radiographs and dental records were reviewed for supernumerary teeth. For each patient with supernumerary teeth, were recorded the demographic variables, number, location, eruption status, type, and morphology, the developmental stages. Descriptive statistics were performed and results were tabulated. Results: Supernumerary teeth were detected in 17 subjects (0.86%), of which 13 were males and 4 were females with a male to female ratio of 3.25:1. Of the 17 patients, 64.7% had one supernumerary tooth while the others had two. The majority (78.3%) of the supernumeraries were located in the maxilla. Around 56.5% of the supernumeraries found in this study were located in the premaxilla. Half of the supernumeraries (52.2%) were erupted, and 47.8% were impacted. Mesiodens was the most frequently seen supernumerary teeth followed by distomolars and premolars. Most of the supernumeraries were fully developed, while 21.7% displayed only crown formation. Conclusion: The prevalence of supernumerary teeth in the study sample was found to be 0.86% and the most frequent type was mesiodens. Supplemental morphology was found to be the most common form of supernumerary teeth.

Abstract Objective: To determine the frequency and characteristics of mesiodens in Indian school children. Material and Methods: 1232 radiographs of patients attending the Department of Oral Medicine and Radiology of the age group of 4-15 years studied for the present retrospective study. The intraoral periapical radiographs and occlusal radiographs of the premaxilla were examined to determine the presence of mesiodens. The data regarding the presence of mesiodens, number, position, location on the arch, shape and associated complications were recorded. Results: Eleven patients had 14 mesiodens, with a frequency of 0.8%. The ratio of boys to girls was 1.2:1. Maximum mesiodens observed in the age group of 7-9 years. Most of the mesiodens were conical in shape and found on the palatal side. Fifty percent of the mesiodens were unerupted. The majority of patients (57.1%) had vertically positioned mesiodens. Midline diastema was the most common complication due to mesiodens (66.7%). Conclusion: Routine check-up during the primary dentition and mixed dentition stages helps for early detection of mesiodens and thus preventing complications. Early identification is useful for planning comprehensive management, initiating proper consultation and referral for evaluation and treatment.

Objective: To identify the dental anomalies that can modify the occlusal characteristics and their distribution in these occlusal alterations in the skeletal patterns of children. Material and Methods: We analyzed charts, panoramic and periapical radiographs of children aged 5 to 12 years from 2009 to 2012. The facial pattern was evaluated through subjective face analysis and cephalometric data, as well as the occlusion of patients with and without (control) dental anomalies. The relationship between the presence of dental anomalies and malocclusion was analyzed by the Chi-square test with significance level of 5%. Results: 73 children (27.8%) presented dental anomalies, being 49.3% in girls and 50.7% in boys in a total of 88 teeth involved. Anomalies observed in decreasing order were: enamel hypoplasias, eruptive ectopias, agenesis, supernumerary teeth, corono-radicular dilaceration, microdontia, transposition and imperfect amelogenesis. Of these, 22.2% presented associated dental anomalies, whose ectopic eruption with enamel hypoplasia were the most frequently encountered. When comparing the control group with children with dental abnormalities it was observed a significant relationship between the presence of dental anomalies and malocclusion (p<0.05). The most frequent alteration among patients with dental anomalies was deep overbite (24.6%), followed by crowding (23.3%), posterior crossbite (14.2%), anterior open bite (12.9%) and anterior crossbite (0.3%). Conclusion: Dental dysgenesis interferes with the development of occlusion and the resulting occlusal problems are distributed differently, taking into account the skeletal facial pattern in patients with and without dental anomalies.

Objective: To determine the prevalence of dental developmental anomalies among patients visiting the dental clinics at Ajman University, United Arab Emirates. Material and Methods: This retrospective study consisted of 425 digital panoramic radiographs. The study sample included people in the United Arab Emirates who have visited the outpatient dental clinics at the Faculty of Dentistry, at Ajman University. These OPGs have been evaluated for the presence of dental anomalies such as: Macrodontia, Microdontia, Talon cusp, Taurodontism, Dilaceration, Ectopic Eruption, Supernumerary teeth or roots, Fusion, Gemination, and Concrescense. Results: 80.7% had at least 1 anomaly, with the maximum of 5 anomalies presented in 1.2% of the sample. Dilacerations were the most commonly identified anomaly (61.4%), followed by missing third molars (22.8%), and Ectopic Eruption (15.5%) where (12.9%) of this anomaly has affected the maxillary canines. Hypercementosis (10.2%) followed by Microdontia (4.6%), which was mostly seen in the Upper laterals. Taurodontism accounted for (4.1%), Macrodontia (2.3%) and Talon cusp (2.3%). Gemination, Dens Invaginatus, and Concrescence were separately present in 1.1%, each one, of the cases observed. Conclusion: Variations in data and results among different studies suggest the impact of racial, genetic and environmental factors. The high frequency of dental anomalies emphasize the need of early detection and diagnosis which can be achieved through radiographic imaging, this would aid in further awareness to minimize any means of complexity in dental problems.

ABSTRACT Mesiodens is the term used for describing the supernumerary tooth that occurs in the maxilla, between the central incisors, in the midline region. These may erupt in the oral cavity or keep themselves impacted. Their presence causes cleaning inadequate, impossibility or difficult of the eruption of the regular teeth and having the aesthetic compromised. This paper aims at showing that early identification of supernumerary teeth, planning and correct approach, allow the preservation of the teeth and adjacent structures. This article presents the clinical case of a seven-year-old child, male, who sought for treatment complaining that teeth 11 didn't appear in the buccal cavity. Clinical and radiographic exams were done and they demonstrated the presence of the supernumerary tooth. The plan of treatment aimed at the correct localization, extraction of this supernumerary tooth and continuous follow up of the case.
RESUMO Mesiodens é o termo utilizado para denominar o dente supranumerário que ocorre na maxila, entre os incisivos centrais, na região de linha média. Esses podem irromper na cavidade oral ou ficarem impactados. A sua presença acarreta higienização inadequada, dificuldade ou impossibilidade de erupção dos dentes regulares e comprometimento da estética. O presente trabalho objetiva mostrar que a identificação precoce de dentes supranumerários, o planejamento e abordagem corretas, permitem a preservação dos dentes e estruturas adjacentes. Este artigo apresenta o caso clínico de criança de 7 anos de idade, gênero masculino, cujos pais procuraram por tratamento com queixa de não esfoliação do dente 51. Foram realizados exames clínicos e radiográficos e estes demonstraram a presença de dente supranumerário invertido. O plano de tratamento teve por objetivo a correta localização, exodontia do mesiodens que não irromperia por ser invertido; e contínuo acompanhamento do caso.
RESUMO
A presença de dentes supranumerários pode causar alterações funcionais e estéticas, principalmente quando localizados na região anterior da maxila, contando, ainda, com complicações na erupção do elemento dental permanente da área afetada. São definidos como dentes de desenvolvimento anormal que podem ocorrer tanto na dentição decídua como na dentição permanente, podendo ser únicos ou múltiplos, uni ou bilaterais permanecer impactados ou erupcionar na cavidade bucal e a sua etiologia permanece ainda desconhecida. A prevalência varia entre 0,8% e 3,7%, em diferentes estudos apresentados, sendo que o sexo masculino é o gênero mais prevalente. Frequentemente eles são diagnosticados em exames de rotina, uma vez que, na maior parte dos casos, são assintomáticos. Quando diagnosticados, a remoção cirúrgica está indicada para que o mesmo não venha causar interferência na dentição permanente. Este artigo apresenta o relato do caso de uma criança de 08 anos de idade que apresentava um dente supranumerário na região dos incisivos centrais superiores e o tratamento realizado foi a exodontia e, posteriormente, tratamento ortodôntico preventivo
The occurence of supernumerary teeth can cause functional and aesthetic changes, particularly when located in the anterior maxilla, as well as complications in the eruption of permanent dental element in the affected area. Such term is defined as abnormal teeth development that may occur either in the primary dentition or in permanent dentition. They can be single or multiple; unilateral or bilateral; remain impacted or erupt in the oral cavity and its etiology remains unknown. The prevalence varies between 0.8% and 3.7% in different studies, and the male is the most prevalent gender. Often they are diagnosed during routine examinations, and are asymptomatic in the majority of the cases. When diagnosed, removal surgery is indicated in order to remove any interference in the permanent dentition. This article presents a case report of a 8 years old patient who presented a mesiodens between upper central incisors and was treated by tooth extraction followed by preventive orthodontic treatment

Dentre os defeitos do desenvolvimento craniofacial, a Hiperdontia representa uma alteração de número do desenvolvimento dentário relevante, devido a sua alta prevalência e ao seu potencial para comprometer funcional e esteticamente os pacientes acometidos. O presente trabalho descreve o caso de um paciente de 5 anos de idade, acometido pelo desenvolvimento de dois elementos dentários supranumerários em região anterior de maxila. O caso foi diagnosticado a partir de avaliação radiográfica associada à erupção ectópica de um dos elementos supranumerários por face palatina dos incisivos superiores decíduos, os quais se apresentavam com mobilidade fisiológica devido ao desenvolvimento de seus sucessores. O tratamento eleito para o caso foi a extração dos elementos decíduos com mobilidade e do elemento supranumerário erupcionado, optando-se pela remoção do elemento supranumerário incluso em momento posterior, uma vez que este não se encontrava associado a nenhum comprometimento funcional ou estético e também pelo fato de que a remoção do mesmo geraria alta morbidade ao paciente pediátrico. O caso descrito salienta a importância do cirurgião no acompanhamento do desenvolvimento craniofacial humano, uma vez que este pode ser acompanhado de distúrbios significativos. Além disso, o presente caso alerta a comunidade odontológica para a importância do bom planejamento e conduta terapêutica adequados para cada caso
Among the defects of craniofacial development, Hyperdontia represents a relevant number of changes of the tooth development, due to its high prevalence and its potential for functional and aesthetically compromising the affected patients. This paper describes the case of a 5 years-old patient, affected by the development of two dental elements supernumerary in the anterior maxilla. The case was diagnosed from radiographic evaluation associated with clinical aspect of ectopic eruption of the supernumerary elements by palatal face of the upper deciduous incisors, which presented with physiological mobility due to the development of their successors. The treatment chosen for the case was the extraction of the deciduous elements mobility and supernumerary element erupted opting up by removal of the supernumerary element included at a later stage, since this was not associate with any functional or esthetic damage, and also by the fact that the removal of that would generate high morbidity to pediatric patient. This case emphasizes the importance of dental surgeon in monitoring of human craniofacial development, since this may be accompanied by significant disorders. Moreover, this case alerts the dental community to the importance of good planning and adequate therapeutic approach for each case

The occurrence of hypodontia (absence of teeth) and hyperdontia (presence of supernumerary teeth) in the same patient is a rarely seen condition in dental practice. Early diagnosis and adequate treatment are very important when addressing this abnormality in the mixed dentition. The approach will depend on the severity of the case and the timing of diagnosis. This paper reports the case of an 11-year-old patient with absence of the permanent maxillary lateral incisors and the mandibular second premolars, with concomitant presence of a supernumerary tooth in the region of the right mandibular lateral incisor. Based on physical and radiographic examination findings, a diagnosis of hypo-hyperdontia was made. The diagnostic and therapeutic management of the case is discussed. The treatment adopted was surgical removal of the supernumerary teeth and esthetic restoration to transform the permanent mandibular canines into lateral incisors.
A ocorrência de hipodontia - ausência de dentes - e hiperdontia - presença de dentes a mais - em um mesmo paciente é uma condição pouco freqüente na clínica odontológica. O diagnóstico precoce e a realização de um tratamento adequado são muito importantes para a abordagem deste tipo de anomalia na dentição mista. A abordagem dependerá da complexidade de cada caso e do momento de diagnóstico da condição. Nesse artigo é relatado um caso de uma paciente com 11 anos de idade com a ausência dos incisivos laterais permanentes superiores e dos segundos pré-molares inferiores, concomitante com a presença de um dente supranumerário na região de incisivo lateral superior direito. Com base no exame físico e radiográfico chegou-se ao diagnóstico de hipo-hiperdontia. As condutas para o diagnóstico e tratamento do caso são abordadas e discutidas. O tratamento adotado foi a remoção do dente supranumerário e a transformação estética dos caninos permanentes superiores em incisivos laterais.
