RESUMEN
The objective of this article is to report the clinical case and 4-year follow-up of a 5-year-old child with multiple dental anomalies, emphasizing the importance of early diagnosis and use of combined pediatric surgery and orthodontic approaches. A 5-year-old boy, accompanied by his mother, sought dental care for dental caries and tooth pain. Clinical and radiographic examinations revealed active caries, a supernumerary primary tooth in the region of the mandibular right second premolar, and severe ankylosis of the primary mandibular right second molar. The treatment plan involved extraction of the supernumerary tooth as well as sectioning and extraction of the ankylosed molar. When the patient was 6 years old, the permanent mandibular right first molar showed signs of an altered eruptive process, and orthodontic treatment was initiated. A unilateral band-and-loop space maintainer with coil springs designed to move the permanent first molar was placed on the primary first molar. A new panoramic radiograph, obtained when the patient was aged 7 years, suggested the presence of an odontoma in the apical region of the primary maxillary right canine. Surgical removal and histopathologic examination of the lesion confirmed that it was a developing odontoma. After surgery, due to occlusal anomalies that included transverse maxillary deficiency, deep overbite, and midline deviation, the patient underwent rapid maxillary expansion therapy with a Haas-type appliance. When the patient was 8 years old, orthodontic treatment continued with a removable palatal Hawley expander and a orthodontic mandibular lingual arch. Currently, at the age of 9 years, the child is still undergoing fixed orthodontic treatment after surgical exposure of the impacted permanent maxillary right canine and bonding of an orthodontic attachment to enable traction. A multidisciplinary approach to the management of dental anomalies promotes a favorable prognosis and ensures comprehensive treatment of young patients.

Odontoma is the most common odontogenic tumour derived from both epithelial and mesenchymal components of the tooth-forming apparatus. It is commonly diagnosed in the second and third decades of life when a radiograph is taken for some other purpose, as most cases are asymptomatic. This case involves a young boy, with the chief complaint of pain and swelling in the lower left back region. An intraoral examination revealed a carious and hypoplastic left permanent mandibular first molar. Although the molar was suspected as the source of his symptoms, radiographic imaging revealed multiple odontomas and missing second and third molar tooth buds. This case highlights the pathological effects of odontomas on surrounding teeth, including the malformation of the first molar and aplasia of the second and third molars. The sole management depends on the early diagnosis, histopathological examination to rule out malignancy and conservative surgical excision of these tissues.

Odontome gelten zusammen mit den Amelo- blastomen als die häufigsten odontogenen Tumoren. Sie entstehen während der embryo- nalen Zahnkeimentwicklung durch fehlerhaft differenziertes Keimgewebe und werden daher auch als Hamartome bezeichnet. Somit sind sie also strenggenommen keine klassischen Neoplasien.

Odontogenic tumors are rare tumors of the jaws that arise from remnants of the tooth forming apparatus. Some odontogenic tumors demonstrate strong predilection for pediatric patients including the unicystic ameloblastoma, adenomatoid odontogenic tumor, ameloblastic fibroma, ameloblastic fibro-odontoma, odontoma, and primordial odontogenic tumor. In this review, we discuss the clinical, radiographic, histopathologic, and molecular characteristics of select odontogenic tumors that demonstrate pediatric predilection and review management.

Introdução: o odontoma é considerado como um frequente tumor odontogênico benigno, podendo ser classificado em tipo composto ou tipo complexo. O cisto dentígero é o mais comum entre os cistos odontogênicos de desenvolvimento, onde envolve a coroa da unidade dentária no nível da junção amelocementária. Há poucos estudos na literatura do encontro das duas lesões, acometendo o mesmo local na cavidade oral. O diagnóstico pode ser constituído por exame clínico e de imagem. Objetivo: apresentar um caso clínico de odontoma composto e cisto dentígero em região de parassínfise mandibular esquerda abordando as caraterísticas clínicas destas duas lesões e as adequadas formas de tratamento. Relato de caso: paciente do sexo masculino, 16 anos de idade, compareceu ao ambulatório do Centro Odontológico da Escola Bahiana de Medicina e Saúde Pública (Salvador, Bahia), portando encaminhamento de ortodontista, solicitando exodontia da unidade dentária 33 inclusa associada a um odontoma. Ao realizar exames físicos e imaginológicos detectou-se a hipótese diagnóstica de odontoma composto associado a unidade dentária, envolto em folículo pericoronário ou cisto dentígero. Foi realizada biópsia excisional das duas lesões e exodontia da unidade. A análise histopatológica confirmou o diagnóstico para odontoma composto associado a cisto dentígero na unidade 33. Ao acompanhamento de 03 meses, paciente apresentou neoformação óssea da região de parassínfise mandibular, mediante a análise de novos exames imaginológicos. Discussão: há poucos estudos na literatura da associação entre as duas lesões, porém relatos afirmam que o odontoma pode ser encontrado associado aos cistos odontogênicos. Por conta da falta de maiores estudos dessa associação, há escassez de recomendações terapêuticas de acordo com faixa etária e extensão do acometimento das lesões. Considerações finais: lesões comumente assintomáticas, tem o diagnóstico constituído por exame clínico e avaliação de exames de imagem(AU)
Introduction: odontoma is considered a frequent benign odontogenic tumor and can be classified as a compound or complex type. The dentigerous cyst is the most common among developmental odontogenic cysts, where it involves the crown of the dental unit at the level of the cementoenamel junction. There are few studies in the literature on the meeting of the two lesions, affecting the same site in the oral cavity. The diagnosis can be made by clinical and imaging examination. Objective: to present a clinical case of compound odontoma and dentigerous cyst in the left mandibular parasymphysis region, addressing the clinical characteristics of these two lesions and the appropriate forms of treatment. Case report: male patient, 16 years old, attended the outpatient clinic of the Centro Odontológico da Escola Bahiana de Medicina e Saúde Pública (Salvador, Bahia), having been referred by an orthodontist, requesting extraction of the included dental unit 33 associated with an odontoma. Upon physical and imaging examinations, the diagnostic hypothesis of a compound odontoma associated with a dental unit, surrounded by a pericoronal follicle or dentigerous cyst, was detected. Excisional biopsy of the two lesions and extraction of the unit were performed. The histopathological analysis confirmed the diagnosis of compound odontoma associated with dentigerous cyst in unit 33. At the 03-month follow-up, the patient presented bone neoformation in the mandibular parasymphysis region, through the analysis of new imaging exams. Discussion: there are few studies in the literature on the association between the two lesions, but reports state that odontoma can be found associated with odontogenic cysts. Due to the lack of further studies on this association, there is a lack of therapeutic recommendations according to age group and extent of lesion involvement. Final considerations: commonly asymptomatic lesions, the diagnosis consists of clinical examination and evaluation of imaging tests(AU)

Introduction: Ameloblastic fibro-odontoma (AFO) is a benign odontogentic tumor without an aggressive behavior, unlike the similar ameloblastic fibroma. Case Presentation: A 9-year-old boy, with tooth eruption failure, underwent enucleation and curettage of a well-defined variable radiolucent and radio-opaque right mandible lesion. There was odontogenic epithelium with peripheral palisading in a loose myxoid stroma as well as a disorganized component of dentin, enamel, and cementum, features of an AFO. Conclusion: AFO is an odontogenic mixed tumor of epithelium and mesenchyme.

O presente trabalho ilustra e discute essa doença que representa o tumor odontogênico mais comum da prática clínica, o Odontoma. Para tal, apresenta um caso clínico com imagens clínicas e radiográficas esclarecedoras dos aspectos dessa doença, bem como discussão a partir de revisão narrativa de literatura direcionada para a carac-terização da doença. Relata-se o caso de um odontoma composto-complexo, uma forma incomum de odontoma, mas que mantém os demais aspectos usuais, sendo uma mulher de 21 anos com lesão radiopaca em maxila de-tectada devido à não erupção do 23. A remoção cirúrgica seguiu a partir de acesso anterior na maxila e o exame histopatológico mostrou os aspectos típicos de um Odontoma composto e complexo juntos. Independentemente da variante, nota-se que o Odontoma é quase sempre indolente, porém requer cuidados de remoção precoce devido à possibilidade de crescimento, de desenvolvimento de cistos e comprometimento de estruturas adjacentes devido a sua localização e possibilidade de crescimento (AU)
The present work illustrates and discusses this disease that represents the most common odontogenic tumor in clinical practice, the Odontoma. However, an unusual variation of the same is included here in the literature, char-acterized by the exams as a form of compound-complex odontoma additionally causing dentigerous cyst formation and dental impaction. The unusual case occurred in a 21-year-old woman, complaining of missing the tooth 23. The details of the exams allowed the visualization of compound and complex areas in the lesion, cystic formation and dental impaction. The histopathological findings confirmed the diagnosis of the Odontoma, and the interpreta-tion with the set of other exams led to the final diagnosis of Compound-complex odontoma with dentigerous cyst. The present case highlights the need for early removal of Odontoma due to the possibility of developing cysts, compromising adjacent structures, in addition to its growth potential already reported in the literature (AU)

Ameloblastic fibro-odontoma (AFO) is a rare benign mixed odontogenic tumor that affects children and young adults. AFO occurs mainly intraosseous. Extraosseous AFO is extremely rare. We report 2 cases of rare peripheral ameloblastic fibro-odontoma in 2- and 12-year-old female patients. Microscopic examination revealed a benign proliferation of odontogenic epithelium associated with a dentinoid material distributed within a cell-rich mesenchymal stroma resembling dental papilla. Simple surgical excision of the lesion is usually curative. There was no recurrence after a short period of follow-up. Clinicians should be cognizant of this rare entity, which can be considered in a differential diagnosis of gingival growths that are noted in early childhood.

Compound odontoma has been reported to be the most common of all odontogenic neoplasms and tumor- like lesions. It is a slow-growing, asymptomatic neoplasms found incidentally during a routine radiography examination. In general, the clinical indicators of odontoma may include eruption disturbance (non-eruption of permanent teeth, retention of deciduous teeth), expansion of the cortical bone, teeth malposition and pain. In this case, the presence of odontoma prevented the physiological eruption of permanent mandible incisor. We describe the surgical procedure to remove a compound odontoma of 21 small tooth-like structures localized in the mandible of a child boy associated with an unerupted permanent mandible incisor.

The objectives of the present study were to comprehensively evaluate all the published cases on compound odontoma associated with calcifying odontogenic cyst (COaCOC) in the English literature and to describe the clinical, imaging and therapeutic variables for this condition. In August 2020, an electronic search of the PubMed / MEDLINE, Web of Science, ScienceDirect, Springer, and Scopus databases was carried out. The eligibility criteria included publications with enough information to confirm the diagnosis. Furthermore, we present a clinical case of a 16-year-old male patient with OCCaC, who was treated with enucleation, obtaining favorable and functional results. A total of 32 cases reported in the literature that met the inclusion and exclusion criteria, including ours, were analyzed and discussed. The mayority of the patients were women (n = 17) with an average age of 14.4 years, the maxilla was the most affected bone (n = 22) and the maxillary anterior region was the area with the highest number of cases (n = 18), the main clinical presentations were the volume increase (n = 14) and asymptomatic (n = 14). The choice treatment was enucleation (n = 26) and, in most cases, no recurrence was reported (n = 20). This study allows to update the characteristics of the OCCaC, giving an effective vision of how to treat this rare pathological association made up of two conditions that are completely different from each other.

El objetivo del presente trabajo es describir las técnicas para el diagnóstico y tratamiento de 3 casos clínicos de odontoma en pacientes ortodóncicos. En el caso 1, se trató a un paciente masculino de 17 años, que acudió para interconsulta con el servicio de ortodoncia, ya que no había erupcionado el canino superior izquierdo y el primer premolar superior izquierdo. El estudio anatomopatológico reveló odontoma complejo con áreas pindborgoides y acumulación de células fantasma. En al caso 2 se trató a un paciente femenino de 15 años. El estudio anatomopatológico reveló odontoma complejo. En el caso 3, se trató a un paciente masculino de 28 años que acudió a rehabilitación integral de su boca, y fue derivado a la cátedra de ortodoncia. En la radiografía panorámica se observó una imagen compatible con odontoma. Se remitió una muestra a anatomía patológica que confirmó el diagnóstico de odontoma. Conclusión: el conocimiento adecuado de las características clínicas, radiológicas y patológicas es necesario para un correcto diagnóstico y tratamiento. Es importante el trabajo interdisciplinario ortodoncista - cirujano para tratar estos casos (AU)
The objective of this work is to describe the techniques for the diagnosis and treatment of 3 clinical cases of odontoma in orthodontic patients. In case 1, a 17-year-old male patient was treated who came for consultation with the orthodontic service, since the upper left canine and the upper left first premolar had not erupted. Pathological study revealed complex odontoma with pindborgoid areas and accumulation of ghost cells. In case 2, a 15-year-old female patient was treated. The anatomopathological study revealed a complex odontoma. In case 3, a 28-year-old male patient was treated who attended comprehensive rehabilitation of his mouth and was referred to the orthodontic department. In the panoramic radiography, an image compatible with odontoma was observed. A sample was sent to pathological anatomy, which confirmed the diagnosis of odontoma. Conclusion: Adequate knowledge of the clinical, radiological and pathological characteristics is necessary for a correct diagnosis and treatment. Interdisciplinary orthodontist-surgeon work is important to treat these cases (AU)

Odontomas are benign and the most common odontogenic tumors. They are classified as compound or complex odontomas according to their radiological and histological features. They have slow growth potential and compound odontoma is more common. Since they are generally asymptomatic they may reach in excessive sizes. In our case we would like to present a case with a large (177 denticles) compound odontoma in mandible.

Peripheral odontoma is a very rare odontogenic hamartoma arising in soft tissues. Here, we report a case of peripheral odontoma in a pediatric patient and review the cases published in the literature. An 11-year-old male patient presented a nodular lesion in the anterior region of the palate for over 1 year. Under the clinical hypothesis of fibroma, an excisional biopsy was performed. Histopathological examination revealed the presence of tooth-like structures, formed by enamel, and dentin matrix, occasionally associated with the dental papilla and surrounding pulp tissue, thus, the histopathological diagnosis of peripheral odontoma was established. The patient has been undergoing follow-up for 6 months without any signs of lesion recurrence. Peripheral odontomas are uncommon lesions that usually affect young patients and display a preference for the maxilla and limited growth potential. The recognition of the clinical and histopathological features of the peripheral odontoma is indispensable for the establishment of its diagnosis.

Odontomas are one of the most common tumours of odontogenic origin. They are usually asymptomatic but may be associated with retained primary teeth or missing permanent teeth. Though the exact aetiology is unknown, the postulated causes include trauma, infection, inheritance and genetic mutation. Early diagnosis and management will result in fewer complications. Conservative surgical excision is the treatment of choice. This case report presents a treated case of compound odontoma associated with delayed eruption of the permanent central incisor in a nine-yearsold boy.

Odontomas are variably differentiated, hamartoma-like proliferations of odontogenic epithelium, pulp ectomesenchyme (odontoblasts), and dental matrix. Frogs are polyphyodont and homodont. Their teeth also differ from mammals in that they are restricted to the upper jaw in adults and lack a periodontal ligament and cementum, attaching directly to the underlying bone. Odontomas were identified in an African clawed frog (Xenopus laevis), a false tomato frog (Dyscophus guineti), and a tomato frog of unknown species (Dyscophus sp.). All of the examined odontomas were composed of numerous tooth-like structures comprising an arc of dentinal matrix lined on the convex surface by ameloblasts and on the concave surface by odontoblasts. Masson's trichrome and immunohistochemistry with pan-cytokeratin supported these findings. The pathogenesis of these lesions may be displacement of the dental lamina, which has been shown in research studies to lead to de novo proliferation of dental elements in frogs.
