Cisto ósseo solitário em mandíbula: relato de caso clínico / Solitary bone cyst of the mandible: clinical case report

Objetivo: apresentar um caso clínico de paciente com cisto ósseo solitário em mandíbula e sua evolução após o tratamento de exploração e curetagem cirúrgica por meio de achados radiográficos. Caso clínico: paciente do sexo masculino, 45 anos, compareceu à clínica da Faculdade de Estudos Administrativos ­ Fead. Ao exame clínico, os tecidos se apresentavam dentro dos padrões de normalidade e ao exame radiográfico observou-se área radiolúcida unilocular, limites regulares e bem definidos em região anterior de mandíbula entre ápices dos dentes 33, 32, 31, 41 e 42, sem deslocamento desses. Para confirmação do diagnóstico, além do exame clínico, foi necessário realizar a tomografia de feixe cônico e exploração cirúrgica. Após a exploração cirúrgica foi realizada a curetagem das paredes ósseas e a proservação do caso para acompanhar a sua evolução. Considerações finais: por ser uma lesão de comportamento não agressivo, responde bem a este tipo de tratamento, sendo notável sua melhora durante o período de acompanhamento.(AU)

Objective: To present a clinical case report of a patient with solitary bone cyst of the mandible and its evolution after exploration and surgical curettage treatment through radiographic findings. Case report: A 45-year-old male patient attended the clinic of the School of Administrative Studies - FEAD. The clinical examination showed normal tissues and the radiographic examination showed unilocular radiolucent area and regular and well-defined boundaries in the anterior mandible between the apexes of teeth 33, 32, 31, 41, and 42, without displacement. To confirm the diagnosis, in addition to the clinical examination, cone beam tomography and surgical exploration were required. After the surgical exploration, bone wall curettage and case proservation were performed to monitor the evolution. Final considerations: Considering it is a non-aggressive lesion, it responds well to this type of treatment, with considerable improvement during follow-up.(AU)

Quiste óseo solitario mandibular. Reporte de un caso y revisión de la literatura / Solitary mandibular bone cyst. Case report and literature review

El quiste óseo solitario de la mandíbula es una cavidad intraósea sin recubrimiento epitelial, considerado un pseudoquiste, ha recibido diversas denominaciones debido a su etiología y patogenia inciertas como quiste óseo traumático, quiste óseo solitario y quiste óseo idiopático. Clínicamente suele ser una lesión asintomática, muestra bordes festoneados cuando está localizado entre las raíces dentales, es una cavidad vacía pero puede contener sangre, fluido seroso o serohemático y es descubierta en exámenes radiológicos de rutina. En este artículo se presenta un caso de quiste óseo solitario localizado en el cuerpo mandibular que acomete a un paciente femenino de 17 años de edad con tetralogía de Fallot, revelando aspectos clínicos, diagnósticos e imagenológicos y tratamiento.

Solitary bone cyst of the mandible is an intra-osseous cavity lacking epithelial lining considered a pseudocyst. Due to its uncertain etiology and pathogenesis, it has received several names such as traumatic bone cyst or idiopathic bone cyst. From a clinical perspective, it is oftentimes an asymptomatic lesion, with festooned borders when located between dental roots. It is an empty cavity but might contain blood, serous or serous-hematic fluid and can be perceived in routine X-ray examinations. The present article describes the case of a solitary bone cyst located in the body of the mandible of a 17-year old female patient. Afflicted with Fallot's tetralogy. Clinical, diagnostic and radiologic aspects as well as treatment are described.

Bony window approach for a traumatic bone cyst on the mandibular condyle: a case report with long-term follow-up

Traumatic bone cyst (TBC) occurs preferentially on the mandibular symphysis and body, but rarely on the mandibular condyle. When TBC occurs in the condylar area, it can usually be related with or misdiagnosed as a temporomandibular joint disorder. A 15-year-old female patient visited the Temporomandibular Joint Clinic with a 5-year history of pain and noise localized in the left temporomandibular joint. On imaging, a well demarked oval-shaped radiolucent lesion was observed on the left condyle head. The patient underwent cyst enucleation and repositioning of the bony window on the lateral cortex of the affected condyle head under the impression of subchondral cyst or TBC; however, no cystic membrane was found. The bone defect resolved and showed no recurrence on the serial radiographic postoperative follow-up for 43 months after surgery.

Solitary Bone Cyst-A Case Report with Diagnostic Prospective

Solitary bone cyst is an uncommon non-epithelial lesion of the jaw bones. It was first defined by Lucas and Blum in 1929. It is classified as an intraosseous pseudocyst. They are asymptomatic and are usually seen during routine radiographical examination. According to the 2002 classification of the WHO, traumatic bone cysts are miscellaneous lesions. This report describes an 18-year-old female patient who had a solitary bone cyst in the posterior region of mandible associated with an impacted third molar.

Unusual Aggressive Radiographic Appearance of Simple Bone Cyst (A Case Report and Review of Literature).

Aim: This study reports a rare case of simple bone cyst (SBC) with a radiographic behavior similar to malignancies and a mixed internal structure in a 43 year-old woman who presented to a dental office with clinical symptoms. Presentation of Case: A 43 year-old woman presented to a dental office with chief complaint of pain at left mandibular molars for almost 2 months. She was wearing a cervical collar for some spine problems. The panoramic x-ray showed a radiolucent lesion with well defined non-corticated borders in periapical region of the mandibular left first molar (tooth 36). The tooth was vital. Cone Beam Computed Tomography (CBCT) images showed a lytic lesion with well defined noncorticated borders that destructs the lingual cortical wall without any sign of expansion to soft tissues. The upper border of the mandibular canal was unclear and seemed destructed by the lesion. The internal structure of the lesion seemed mixed. Three months later, the patient reported numbness of her lower lip. CBCT showed an enlargement of the lesion and the presence of buccal cortical perforation was seen. On biopsy the lesion was diagnosed as a Simple Bone Cyst (SBC). Discussion: SBC is often a benign lesion which appears as a radiolucent lesion with scalloped corticated borders. Adversely, current case showS a mixed lesion with buccal and lingual cortical perforation and rapid growth .the concomitant pain, the lower lip numbness and the radiographic appearance suggest the probability of an aggressive local condition or a malignancy Conclusion: SBC may have various radiographic presentations, unusual SBCs (or Traumatic bone cysts TBCs) may show aggressive radiographic characters. In these cases, biopsy and pathological features are necessary for diagnosis.

Cisto ósseo simples: relatos de casos / Simple bone cyst: case reports

Geralmente diagnosticado em radiografias de rotina, o cisto ósseo simples ocorre com pouca freqüência. A etiologia é desconhecida e o diagnóstico diferencial pode estar associado com cisto dentígero, tumor odontogênico ceratocístico, tumor odontogênico adenomatóide, ameloblastoma e granuloma central de células gigantes. O tratamento é cirúrgico, através de perfuração do osso cortical. Na maioria dos casos, de uma cavidade vazia, sem qualquer cápsula ou revestimento epitelial, são encontrados, mas pode ter conteúdo líquido. A perfuração do osso cortical mandibular provoca uma resposta que resulta com a reparação óssea da cavidade vazia. Este artigo analisa o assunto e apresenta dois casos desta entidade e discute os possíveis fatores interferentes no processo de cura da lesão... (AU)

Usually diagnosed in routine radiographs, the simple bone cyst occurs infrequently. Etiology is unknown and differential diagnosis has to be made with dentigerous cyst, keratocystic odontogenic tumor, adenomatoid odontogenic tumor, ameloblastoma and central giant cell granuloma. Treatment is surgical, by perforating the cortical bone. In most cases an empty cavity, without any capsule or epithelial covering, is encountered, but it may have a liquid content. Perforation of the mandibular cortical bone elicits a response that results in bone repair of the empty cavity. This article reviews the subject and presents two cases of this entity and discusses the possible factors that could interfere in healing course... (AU)

Traumatic bone cyst-anterior mandibular region.

Traumatic bone cyst(TBC) is rare cyst .it is also known as FALSE CYST because it does not have epithelial lining. Causes of TBC is unknown , but number of patients have history of prior trauma. It is more common in mandible with slight predilection to male.TBS of the jaws are often polymorphic, show scalloped borders when located between the teeth roots, are devoid of an epithelial lining, and are usually empty or contain blood or a straw-coloured fluid. The numerous synonyms referring to these lesions reflect their uncertain nature (eg , solitary bone cyst, simple bone cyst). Histology usually shows fibrous connective tissue or only bone.

Cisto ósseo traumático em pacientes submetidos ao tratamento ortodôntico / Traumatic bone cyst in patients undergoing orthodontic treatment

Este artigo objetivou avaliar a prevalência do cisto ósseo traumático (COT) por meio da coincidência entre o diagnóstico do COT e o paciente que se apresenta para tratamento ortodôntico. A amostra constou de 12.805 pacientes oriundos de clínicas privadas, cursos de graduação e pós-graduação recrutados no período de 1990 e 2009. Inicialmente, cada profissional foi calibrado com radiografias panorâmicas que não fizeram parte da pesquisa, sobre as características e o diagnóstico de COT. O método consistiu na aplicação de um questionário objetivo, respondido por ortodontistas, com o objetivo de avaliar a prevalência de cisto ósseo traumático no contingente total de pacientes de cada profissional. O questionário de avaliação interrogou cada profissional sobre o número total de pacientes, bem como a quantidade de pacientes com diagnóstico de COT, após a criteriosa avaliação dos exames radiográficos panorâmicos. Evidenciou-se uma prevalência de 0,02% de cisto ósseo traumático na população estudada. A prevalência de COT foi muito baixa (1 em cada 4268 pacientes ortodônticos examinados), entretanto, por ser uma lesão assintomática, é de fundamental importância a realização de exames imaginológicos a partir dos 10 anos de idade para o seu diagnóstico.

His article aimed to assess the prevalence of traumatic bone cyst (TBC) in patients undergoing orthodontic treatment based on the evaluation of panoramic x-rays. The sample was composed of 12.805 patients from private practices, graduation and post-graduation programs recruited between 1990 and 2009. At first, each professional was calibrated with panoramic radiographs that were not part of the research on the characteristics and diagnosis of TBC. The method consisted on a objective questionnaire answered by orthodontists with the aim of evaluating the prevalence of traumatic cyst bone on the patients from each professional. The evaluation questionnaire asked each professional about the total number of patients as well as the number of patients diagnosed with TBC, after careful evaluation of panoramic radiographs. A prevalence of 0.02% of traumatic bone cyst (TBC) was found in the investigated population. The prevalence of TBC was very low (1 out of 4268 orthodontic patients examined). However, since TBC is an asymptomatic lesion it is of paramount importance to establish its diagnosis by having imaging examinations performed starting at age 10.

Traumatic bone cyst?: report of a case diagnosed after orthodontic treatment / Cisto ósseo traumático?: relato de caso diagnosticado após tratamento ortodôntico

Traumatic bone cyst is an uncommon lesion that may be incidentally diagnosed in routine dental treatment. Clinical features may comprehend asymptomatic lesion, with no bone expansion, most commonly located on the posterior mandible area. The lesion affects most often patients on second decade of life. Radiographically traumatic bone cyst it is manifested as a well-defined radiolucent area with a festooned pattern around the apexes of the adjacent teeth. Routine radiographies play an important role in diagnosing this lesion. In most of the cases the diagnosis is confirmed by the finding of an empty cavity during surgical management. Simple exploration of the cyst may be the curative procedure for this lesion. The present study reports a clinic case in which traumatic bone cyst had been diagnosed during final documentation at the end of the orthodontic treatment.

O cisto ósseo traumático é uma condição incomum que pode ser diagnosticada ao acaso em tratamento odontológico de rotina. Os aspectos clínicos envolvem lesão assintomática, sem expansão óssea, mais comumente localizada na região posterior da mandíbula, afetando preferencialmente indivíduos na segunda década de vida. Radiograficamente, o cisto ósseo traumático apresenta uma área radiolúcida bem definida, com padrão festonado ao redor dos ápices dos dentes adjacentes. As radiografias de rotina cumprem papel importante na identificação da lesão. A confirmação do diagnóstico é geralmente confirmada no ato cirúrgico, quando uma cavidade vazia é encontrada. Este relato de caso envolve uma situação clínica em que o cisto ósseo traumático foi diagnosticado a partir da documentação radiográfica ao final de um tratamento ortodôntico.
