Quiste bucal mandibular infectado bilateral: reporte de caso estudiado con CBCT / Bilateral mandibular infected buccal cyst: report of a case studied by CBCT

El quiste bucal mandibular infectado (QBMI), también conocido como quiste de bifurcación, es un quiste odontogénico inflamatorio poco frecuente y descripto por primera vez por Stoneman y Worth. Ha sido incluido en la clasificación de la OMS de quistes y tumores odontogénicos en 1992. Este quiste suele darse, específicamente, en pacientes entre 6 y 13 años, y su localización más frecuente son el primer y segundo molar permanente y, eventualmente, segundo premolar. Su fisiopatología sigue sin estar clara y se han propuesto múltiples teorías. Este quiste se observa como una inflamación en el vestíbulo del molar afectado. Los síntomas frecuentes son dolor en el área afectada y supuración, pero también muchos casos permanecen asintomáticos. Radiográficamente se describe como un área radiolúcida circunferencial. El quiste está revestido con un epitelio escamoso no queratinizado con infiltrado inflamatorio de células en el tejido conectivo. La mayoría de las características clínicas e histológicas son similares a las reportadas para los quistes paradentales, de ahí la importancia de un buen diagnóstico radiográfico complementario en base a tomografía computada de haz cónico. Los enfoques conservadores suelen ser el tratamiento de elección, con la enucleación del quiste y el seguimiento del diente afectado (AU)

Mandibular infected buccal cyst (MIBC), also known as bifurcation cyst; it is a rare inflammatory odontogenic cyst first described by Stoneman and Worth. It was included in the WHO classification of cysts and odontogenic tumours in 1992. It usually occurs, specifically, in patients between 6 and 10 years of age and its most frequent location is the first and second permanent molars, and eventually the second premolar. Its pathophysiology remains unclear and multiple theories have been proposed. This cyst is seen as an inflammation in the vestibule of the affected molar. Frequent symptoms are pain in the affected area and suppuration, but many cases remain asymptomatic. Radiographically it is described as a circumferential radiolucent area. The cyst is lined with a nonkeratinized squamous epithelium with an inflammatory cell infiltrate in the connective tissue. Most of clinical and histological characteristics are like those reported for paradental cysts, hence the importance of a good complementary radiographic diagnosis based on cone beam computed tomography. Conservative approaches are usually the treatment of choice, with enucleation of the cyst and monitoring of the affected tooth (AU)

Cisto ósseo traumático associado a odontoma composto: relato de um caso incomum / Aneurismal bone cyst with a compound odontoma: unusual case report

Introdução: o cisto ósseo traumático (COT) é um pseudocisto que se apresenta assintomático e é descoberto frequentemente em exames de rotina. Outra lesão também presente nos maxilares é o odontoma, sendo dividido em dois subtipos, o composto e o complexo; os odontomas são geralmente descobertos como um achado acidental, visto que não apresentam sintomatologia. Objetivo: relatar um caso incomum de um COT, associado à odontoma composto (OC). Relato de caso: paciente do gênero masculino, 16 anos de idade, compareceu à clínica escola de odontologia da Universidade Federal de Campina Grande (UFCG), campus Patos, PB, referenciado pelo cirurgião-dentista após solicitar exame radiográfico para tratamento ortodôntico e observar lesão radiolúcida em região anterior da mandíbula. Durante a anamnese, o paciente não relatou nenhuma alteração sistêmica ou doença de base, mas relatou trauma de infância na região acometida. No exame clínico intraoral, não foi observado nenhum aumento de volume na região. Realizou-se palpação na região, não havendo relato de dor. Ao analisar a radiografia panorâmica, observou-se a presença de pequenas estruturas calcificadas com radiopacidade semelhante às estruturas dentárias, delimitada por uma linha radiolúcida, sugestiva de OC. Para melhor localização, delimitação, relação com estruturas anatômicas e planejamento cirúrgico da lesão, foi solicitado um exame de tomografia computadorizada de feixe cônico (TCFC). Considerações finais: com base nos achados clínicos e radiográficos, optou-se por abordagem cirúrgica da lesão cística e enucleação do OC, sob anestesia local. No pós-operatório de um ano, o paciente evoluiu satisfatoriamente sem queixas clínicas.(AU)

Introduction: traumatic bone cyst (TBC) is a pseudocyst that usually presents asymptomatically and is found frequently in routine exams. Another lesion also present in the jaws is odontoma. The odontoma is divided into two subtypes, the compound and the complex; odontomas are usually discovered as an accidental finding, since they do not present symptomatology. Objective: the present article aims to report an unusual case of a TBC associated with a composite odontoma. Case report: a 16-year-old male patient attended the Clinic School of Dentistry of the Universidade Federal de Campina Grande (UFCG), Patos-PB campus, referenced by the dentist after identify radiolucent lesion in the anterior region of the mandible on radiographic examination for orthodontic treatment. During the anamnesis, the patient did not report any systemic alteration or underlying disease, but reported trauma in the region affected in childhood. The intra oral clinical examination, was not observed any increase in volume in the region. Palpation was performed in the region, and there was no report of pain. When analyzing panoramic radiography the presence of small calcified structures with radiopacity similar to dental structures was observed, delimited by a radiolucent line, suggestive of compound odontoma. To better location, delimitation, compared with anatomy and surgical planning of the injury, it was requested an cone beam computed tomography (CBCT). Final considerations: based on the clinical and radiographic findings, we opted for a surgical approach to cystic lesion and enucleation of composite odontoma, under local anesthesia. In the one-year postoperative period, the patient progresses satisfactorily without clinical complaints.(AU)

Bilateral mandibular buccal bifurcation cyst: a case report emphasizing the role of imaging examination in the diagnosis

A mandibular buccal bifurcation cyst is an inflammatory cyst that usually occurs on the buccal aspect of the permanent mandibular first molar of children. This lesion is diagnosed by an association of radiographic, clinical, and histological features. We report a bilateral case of mandibular buccal bifurcation cyst and discuss the main findings of this entity. A 7-year-old girl presented pain and delayed dental eruption in the posterior mandibular region. A cone beam computed tomography was performed and revealed hypodense lesions involving the crown and root of the mandibular first molars, with expansion of the buccal cortical and lingual tilting of the molar roots. A biopsy was carried out, and the common features of an inflammatory odontogenic cyst were histologically observed. The final diagnosis was bilateral mandibular buccal bifurcation cyst. Clinicians need to be aware of this diagnostic possibility in cases of mandibular cysts in children­especially when bilateral­to perform the correct treatment, which should not involve the extraction of the affected tooth.

Defeito ósseo de Stafne e a importância da tomografia no diagnóstico: um relato de caso / Stafne's bone defect and importance of tomography in diagnosis: a case report

Objetivo: relatar o caso de um paciente idoso portador de defeito ósseo de Stafne. Relato de caso: paciente do sexo masculino, 74 anos de idade, foi atendido na Clínica de Odontologia da União Metropolitana de Educação e Cultura, e, após realização de radiografia panorâmica, foi evidenciada uma imagem sugestiva do defeito, sendo o paciente orientado a realizar a tomografia computadorizada fan beam para a confirmação diagnóstica. Considerações finais: o defeito ósseo de Stafne é definido como uma depressão lingual na mandíbula, de forma arredondada ou ovoide, que varia de 1 a 3 cm em diâmetro, com margens ósseas muito densas e bem definidas. Apresenta-se, radiograficamente, como uma imagem radiolúcida, circunscrita e unilocular na região posterior da mandíbula, abaixo do canal mandibular. É geralmente detectado em exames radiográficos de rotina, como a radiografia panorâmica, e a confirmação do diagnóstico geralmente é obtida pela realização da tomografia computadorizada fan beam ou de cone beam, por conta da obtenção de imagens que possibilitam a avaliação tridimensional, descartando, assim, outros tipos de lesões. Por se tratar de uma variação anatômica, a conduta é proservar o caso. (AU)

Objective: the objective of the following work was reported in the case of an elderly male patient. Clinical case: male patient, 74 years-old, who was attended at the Dentistry Clinic of the Metropolitan Union of Education and Culture, and after a panoramic radiograph, an image suggestive of the defect was evidenced. patient oriented to perform a Fan Beam Computed Tomography scan for diagnostic confirmation. Final considerations: the Stafne bone defect is defined as a lingual depression in the mandible, rounded or ovoid, ranging from 1 to 3 cm in diameter, with very dense and well defined bone margins. It presents, radiographically, as a radiolucent, circumscribed and unilocular image in the posterior region of the mandible, below the mandibular canal. It is usually detected in routine radiographic examinations as a panoramic radiograph, being a confirmation of the diagnosis obtained by performing the Fan Beam Computed Tomography or Cone Beam, due to obtaining images that allow a three-dimensional evaluation, thus discarding other types of injuries. Because it is an anatomical variation, the conduct is to preserve the case. (AU)

Resolución quirúrgica de quistes de los maxilares con técnica descompresiva / Surgical resolution of jaw cysts with decompressive technique

Podemos definir "quiste" como una bolsa conectivoepitelial, tapizada en su interior por epitelio y recubierta en su cara externa por tejido conectivo, que encierra un contenido líquido o semisólido. Según su patogénesis, los clasificamos como lesiones de desarrollo o de tipo inflamatorio (1, 17). Tanto los quistes de desarrollo como los inflamatorios se caracterizan por un crecimiento lento y una tendencia expansiva. A pesar de ser entidades con un comportamiento benigno, pueden alcanzar un tamaño considerable si no se diagnostican y se tratan a tiempo (2). El tipo de tratamiento de la lesión está condicionado por múltiples factores como el tamaño de la misma, su localización, su relación con estructuras anatómicas vecinas, la posible afectación de estructuras dentales, entre otras. (3) El objetivo es elegir la modalidad de tratamiento que conlleve el menor riesgo posible de recurrencia, el cuidado, en lo posible, de las estructuras nobles vecinas y, por supuesto, la erradicación de la lesión. (4) Dentro de los tratamientos de los quistes maxilares, podemos mencionar la enucleación total de los mismos o técnica de Parstch II, la marsupialización o técnica de Parstch I y la técnica descompresiva, también llamada técnica de Waldron- Axhausen. El objetivo de este trabajo es el de mostrar un caso clínico donde se realizó la técnica descompresiva para el tratamiento de un quiste inflamatorio en el maxilar inferior en íntimo contacto con el nervio dentario inferior y la basal mandibular (AU)

We can define "cyst" like a connective-epitelial bag, upholstered inside by epithelium and covered on the outside by connective tissue, enclosing a liquid or semisolid contents. According to its pathogenesis, classify them as development or inflammatory (1, 17). Injury both the inflammatory and developing cysts are characterized by slow growth and an expansionary trend. Despite being entities with a benign behavior, they can reach a considerable size if not diagnosed and treated in time. (2) The type of treatment of injury, is determined by multiple factors such as the size, its location, its relationship with neighboring anatomical structures, possible involvement of dental structures, among others. (3) The objective is to choose the modality of treatment involving the least possible risk of recurrence, care, as far as possible, of the neighboring noble structures and of course the elimination of the lesion. (4) Inside of the Maxillary cysts treatments we can mention the enucleation total thereof or technical Parstch II, the marsupialization or technique of Parstch I and the decompression technique, also called Waldron - Axhausen technique. The objective of this work is the show a clinical case where took place the decompression technique for the treatment of inflammatory cyst in the lower jaw in intimate contact with the inferior alveolar nerve and the mandibular basal (AU)

Tratamiento conservador de un proceso expansivo tipo quístico con técnica mínimamente invasiva: caso clínico / Conservative treatment of an expansive processof cystic type with minimally invasive technique:clinical case

Los quistes son cavidades patológicas que adquieren importancia en el ámbito odontológico debido a la gran frecuencia en la que se encuentran en los maxilares y por el rol que el odontólogo presenta en su detección. Dentro de las lesiones tipo quísticas, mencionamos al quiste apical en bolsa donde existe una comunicación entre este y el conducto radicular, cuya curación puede lograrse a través de la terapia endodóntica. En el presente caso clínico se demostró cómo la pasta de hidróxido de calcio colocada en forma temporaria y en sucesivas sesiones en el interior de los conductos de los cuatro incisivos inferiores afectados por un gran proceso quístico, permitió la resolución paulatina hasta la erradicación completa del mismo. Se realizaron sucesivos controles clínicos y radiográficos mediante Rx periapicales, ortopantomografías y tomografías Cone Beam; dichos controles indicaron el momento oportuno de repetir el procedimiento de acuerdo a los resultados obtenidos en la disminución de las dimensiones del proceso quístico, optando por la terapia endodóntica definitiva a los 9 meses. Se destaca la eficacia de este tratamiento conservador, mínimamente invasivo, ante la presencia de ungran proceso quístico, con la finalidad de evitar las técnicas quirúrgicas, en pacientes comprometidos a las citas periódicas necesarias para lograr su erradicación.

The cysts are pathological cavities that acquire importance in the dental field due to the great frequency in which they are found in the jaws and the role that the dentist presents in their detection. Withincysts lesions cyst dental root in pocket can be mentioned, where there is a communication between itand the root canal, whose cure can be achieved through root canal therapy or endodontic therapy. In the present clinical case it was demonstrated how the calcium hydroxide paste placed temporarily andin successive sessions inside root canal of the four lower incisors affected by a large cystic process,allowed the gradual resolution until the complete eradication of it. Successive clinical and radiographic controls were carried out using periapical radiographs, orthopantomographies and Cone Beamtomography, these controls indicated the opportune moment to repeat the procedure according to theresults obtained in the reduction of the dimensions of the cystic process, opting for definitive endodontic therapy at nine months. The effectiveness of this conservative treatment is minimally invasive in the presence of a large cystic process, in order to avoid surgical techniques in patients committed to necessary periodic appointments to achieve eradication.

The effect of decompression as treatment of the cysts in the jaws: retrospective analysis

OBJECTIVES: The purpose of this study is to evaluate the treatment efficacy of enucleation after decompression. MATERIALS AND METHODS: A total of 17 patients with cystic lesion of the jaw were treated with decompression followed by enucleation. Pre- and postdecompression panoramic radiographs were analyzed. RESULTS: The mean percentage of reduction after decompression was 64%. The reaction was graded as good (>80%) in five patients (29.4%), moderate (50%-80%) in nine patients (52.9%), and poor (<50%) in three patients (17.6%). The reduction rate of larger cystic lesions was faster than that of smaller lesions. However, the reduction rate was not affected by age. The duration of follow-up ranged from one to eight years. There were no complications, and one case recurred. CONCLUSION: Decompression is an effective method for the initial treatment of jaw cysts.

Of the ten cases, three cases exhibited complete bone healing and seven cases showed new bone formation.</p><p><b>CONCLUSION</b>Simple bone cysts of the jaws are usually asymptomatic and appear incidentally on routine radiographies. The prevalence is higher in the mandible and young people. The patient usually has no history of trauma, and the bone cavity of lesion is mostly vacant. Curettage of the bone walls of the lesion is suggested for simple bone cysts. Systemic clinical and radiologic follow-up are necessary to ensure successful treatment.</p>

Treatment of nevoid basal cell carcinoma syndrome: a case report

Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is characterized by various embryological deformities and carcinoma formation. It is caused by PTCHI gene mutations and is autosomal dominantly inherited. Some of the main symptoms of NBCCS are multiple basal cell carcinomas, multiple keratocystic odontogenic tumors (KCOTs) of the mandible, hyperkeratosis of the palmar and plantar, skeletal deformity, calcification of the falx cerebri, and facial defomity. Recurrent KCOT is the main symptom of NBCCS and is present in approximately 90% of patients. In NBCCS, KCOTs typically occur in multiples. KCOTs can be detected in patients under the age of 10, and new and recurring cysts develop until approximately the age of 30. The postoperation recurrence rate is approximately 60%. This case report presents a 14-year-old female patient with a chief complaint of a cyst found in the maxilla and mandible. The patient was diagnosed with NBCCS, and following treatment of marsupialization and enucleation, the clinical results were satisfactory.

Radiographic examination evidenced a unilocular area asymptomatic and associated to the apex of the under left incisive, who presented pulp vitality. The patient reported no trauma in childhood, although presenting a scar on the submental region. The clinical diagnosis of traumatic bone cyst was performed, surgical exploration and curettage of the bone defect was the treatment of choice. Postoperative period of one year, the patient progressed satisfactorily without clinical complaints. Conclusion: Presentation non-aggressive behavior, the traumatic bone cyst responds adequately to conservative treatment by surgical curettage.

Quiste residual gigante: presentación de un caso / Residual cyst: a case presentation

FUNDAMENTO: un quiste es una estructura con tendencia a la forma redondeada, constituida por una pared externa de tejido conectivo fibroso, una pared interna formada por un tapiz epitelial. La cavidad quística contiene un material líquido o semilíquido de color cetrino que, cuando se infecta, se convierte en purulento y carmelitoso. El quiste residual puede haber sido anteriormente un quiste lateral o un quiste apical y al haberse extraído el diente, a partir de cuyo periodonto se forma el quiste, se queda en el tejido óseo sin haber sido extirpado. OBJETIVO: presentar un caso al cual se le diagnosticó y trató un quiste residual mandibular que abarcaba la hemiarcada izquierda, que permitió restablecer las funciones masticatorias y estética. CASO CLÍNICO: paciente que fue atendido en la consulta de Cirugía Maxilofacial de la Facultad de Estomatología de Camagüey, con un aumento de volumen en la región lateral izquierda, con antecedentes de trauma anterior que le provocó fractura de mandíbula. Se describen las características clínicas de la enfermedad y el tratamiento quirúrgico realizado, se utilizó para el mismo los principios de la técnica de enucleación. CONCLUSIONES: aunque se han reportados pocos casos en la literatura nacional y extranjera, estos han sido quistes de menor tamaño que incluyen uno o dos dientes, no existen reportes de quistes residuales que involucren toda la arcada o hemiarcada dentaria. Se obtuvieron resultados estéticos satisfactorios con la técnica quirúrgica empleada y no se presentaron complicaciones.

BACKGROUND: a cyst is a structure with a tendency to be rounded, made up of an external wall of fibrous connective tissue, an internal wall composed of epithelial tissue. The cystose cavity contains sallow liquid or semiliquid material that, when becomes infected, gets purulent and brown. A residual cyst could have been previously a lateral cyst or an apical cyst and when the tooth is extracted from the periodontium, the cyst remains in the osseous tissue without being removed. OBJECTIVE: to present a case diagnosed and treated for a mandibular residual cyst that extended over the left hemiarcade. It was possible to re-establish the masticatory and aesthetic functions. CLINICAL CASE: a patient who was treated in the Maxillofacial Surgery consultation of the Faculty of Stomatology of Camagüey. The patient presented a volume increase in the left lateral region and an antecedent of front trauma that caused fracture of the lower jaw. The clinical characteristics of the disease and the surgical treatment conducted are described. The principles of the enucleation technique were used for conducting the surgical treatment. CONCLUSIONS: in spite of the fact that few cases have been reported in the national and foreign literature, these have been smaller cysts that included one or two teeth. There are no reports of residual cysts that extend over all the dental arcade or hemiarcade. Satisfactory aesthetic results were obtained with the surgical technique applied and there were no complications.
