Revisión de la literatura en el diagnóstico imagenológico del quiste dentígero / Review of the literature in the imagenological diagnosis of the dentigerous cyst

El quiste dentígero, incluido dentro de la clasificación de los quistes odontogénicos por la OMS en el 2017, constituye una patología relevante en el área buco maxilofacial. Si bien su crecimiento es lento y asintomático, cuando alcanza grandes dimensiones, tiene capacidad para provocar destrucción ósea en los maxilares, lo que ocasiona alteraciones estéticas y funcionales. Además, presenta una alta prevalencia, con el quiste odontogénico como el más común, después del quiste radicular inflamatorio. La radiología representa una herramienta fundamental en su diagnóstico y muchas veces su detección constituye un hallazgo radiográfico. Normalmente, se emplean técnicas en 2D como la radiografía periapical, panorámica y oclusal, las cuales cumplen un rol muy importante en su detección y diagnóstico. No obstante, debe considerarse que la similitud del quiste dentígero con otros procesos patológicos, tanto a nivel clínico como radiográfico, muchas veces lleva a un diagnóstico y tratamiento inadecuado. Con este trabajo se pretende evidenciar si el advenimiento de nuevas tecnologías como la resonancia magnética y la tomografía computarizada de haz cónico permiten mejorar la posibilidad del diagnóstico del quiste dentígero y distinguirlo de otras lesiones o patologías con las cuales se realiza el diagnóstico diferencial. (AU)

The dentigerous cyst, included in the classification of odontogenic cysts according to the WHO year 2017, constitutes a relevant pathology in the maxillofacial buccal area. Although its growth is slow and asymptomatic, when it reaches large dimensions it has the capacity to cause bone destruction in the jaws, causing aesthetic and functional alterations. In addition, it has a high prevalence, being the most common odontogenic cyst, after the inflammatory root cyst. Radiology represents a fundamental tool in its diagnosis and often its detection constitutes a radiographic finding. Normally 2D techniques such as periapical, panoramic and occlusal radiography are used, which play a very important role in their detection and diagnosis. However, it should be considered that the similarity of the dentigerous cyst with other pathological processes, both clinically and radiographically, often leads to inadequate diagnosis and treatment. This work is intended to show whether the advent of new technologies such as magnetic resonance imaging and conical beam computed tomography, allow to improve the possibility of diagnosis of the dentigerous cyst and distinguish it from other lesions or pathologies with which a differential diagnosis is made.

Quiste dentígero: presentación de un caso clínico y revisión de la literatura / Dentigerous cyst: report of a clinical case and review of the literature

Introduccion: según la clasificación de la oms de 1992, el quiste dentígero o folicular se clasifica dentro de los quistes de desarrollo odontogénicos. Este se origina en la evolución de un germen dentario. La pieza dentaria, generalmente, se encuentra en íntima relación con la membrana quística, adherida al límite amelocementario. El crecimiento es lento y continuo. Radiográficamente se observa una imagen radiolúcida, definida y unilocular. Afecta con más frecuencia al sexo masulino y la proporción de pacientes de 6 a 7 años con quistes dentígero es de solo 9.1%. Caso clínico: paciente masculino de 6 años concurre a la consulta con su abuela presentando inflamación facial del maxilar superior derecho, asintomática. Luego del examen clínico se le solicita una radiografía panorámica. Por su severidad, se le solicita una tomografía computada y se lo deriva para su intervención quirúrgica y análisis de la muestra. Conclusion: el odontólogo clínico debe realizar la anamnesis e inspección clínica y ante la sospecha de una patología, debe solicitar un estudio radiográfico y/o tomográfico complementario. Se puede observar que durante el recambio dentario, es frecuente la presentación de lesiones patológicas que si no son diagnosticadas a tiempo estas podrían malignizarse y llevar al paciente a grandes resecciones quirúrgicas (AU)

Introduction: according to the who classification of 1992, the dentigerous or follicular cyst is classified within the odontogenic development cysts. This originates in the evolution of a dental germ. The dental piece is usually in close relation with the cystic membrane, adhered to the amelocementary limit. The growth is slow and continuous. Radiographically, a radiolucent, defined and unilocular image is observed. It affects the masculine sex more frequently and the proportion of patients from 6 to 7 years with dentigerous cysts is only 9.1%. Clinical case: a 6-year-old male patient attended the consultation with his grandmother presenting facial inflammation of the right upper jaw, asymptomatic. After the clinical examination, a panoramic radiograph is requested. Due to its severity, a tomography where it is then transferred for its surgical intervention and sample analysis. Conclusion: the clinical dentist must perform the anamnesis and clinical inspection and, if pathology is suspected, he or she must request a complementary radiographic and / or tomographic study. In odontopediatry, during dental replacement, it is common the presentation of pathological lesions that if not diagnosed in time they could be malignant and take the patient to large surgical resections (AU)

The dentigerous cyst is defined as a cystic lesion involving the crown of an included tooth, which is attached to the cement enamel junction. Clinically it is manifested by asymptomatic increase in volume, and is usually discovered by routine radiographic examination or by investigation of non-erupted tooth. Radiographically, it presents as a unilocular radiolucent lesion around an even tooth. This study presents a clinical case of a patient with a dentigerous cyst in the posterior region of the mandible, treated surgically by enucleation and exodontia of involved teeth. A 9-year-old male patient attended the Pediatric Dentistry Clinic of the University of Ribeirão Preto (UNAERP), Brazil, complaining of lower left bulging of the face, with marked facial asymmetry, whose panoramic radiographic examination and computed tomography evidenced the presence of large dentigerous cyst. In view of the clinical and radiographic findings, the treatment plan was to enucleate the cyst to allow eruption of the permanent successors, followed by the exodontia of the dental elements 74/75. Surgical treatment was fast and resolute, showing that the choice of treatment should be carefully weighted for each case.

Hybrid lesion formed by a complex odontoma and dentigerous cyst: radiographic and histomorphological findings: a case report

Hybrid lesions of the oral cavity are infrequent and share characteristics with a number of other pathologies. both odontomas and dentigerous cysts are of odontogenic origin, but their simultaneous occurrence is rare and scarce. clinical and radiographic examinations are not conclusive, making their identification difficult, while histopathological studies can reveal their defining characteristics. the aim of this report was to describe the radiographic and histomorphological findings of a hybrid lesion formed by a complex odontoma and a dentigerous cyst, affecting the mandible of a 22-year-old man, from Cartagena, Colombia, who had no relevant medical history, and no symptoms or discomfort in the affected area.

Quiste dentígero: Reporte de un caso / Dentigerous cyst: A case report

Los quistes del maxilar constituyen un conjunto muy variado de entidades, entre las que se incluyen los tumores benignos y malignos de origen odontogénico. Existe poca información sobre la prevalencia de esta patología. Afecta con mayor frecuencia al sexo masculino, entre la segunda y la tercera década de la vida. La proporción de pacientes de 6 a 7 años con quistes dentígeros es de solo 9,1%. El quiste dentígero engloba la corona de un diente permanente normal, impactado, no erupcionado. Suele presentar una sintomatología insidiosa y no se descubre hasta que la tumoración afecta a los órganos vecinos. El objetivo es exponer un caso de quiste dentígero. Si bien es de aparición muy poco frecuente, la presentación de este caso sirve para poner al médico pediatra en conocimiento sobre cómo debe actuar ante una tumoración maxilar unilateral en un niño sano. Se remarca la importancia del manejo multidisciplinario de la entidad.

Maxillary cysts are a diverse group of entities that include benign and malignant odontogenic tumors. Information on the prevalence of this disease is limited. It is more common among males, and usually occurs in the second and third decade of life. The proportion of 6 to 7 year old patients with dentigerous cysts is only 9.1%. Dentigerous cysts encompass the crown of a permanent and unerupted impacted teeth. They are usually slow growing asymptomatic lesions that are not discovered until they affect surrounding organs. The aim of this study is to present an unusual case of dentigerous cyst and to inform the pediatrician about the management of a unilateral maxillary tumor in a healthy child, underlining the importance of a multidisciplinary approach of this disease.

Tomografía computarizada de haz cónico como instrumento complementario de diagnóstico y planeamiento quirúrgico de quiste dentígero: reporte de un caso / Cone-Beam computed tomography as complementary tool in diagnosis and surgical planning of dentigerous cyst: case report

El quiste dentígero es una de las patologías óseas que más frecuentes en el maxilar y la mandíbula. Se evidencia radiográficamente como una imagen radiolúcida y unilocular en la mayoría de los casos. Generalmente es detectado en exámenes de rutina o cuando se investiga la presencia de dientes no erupcionados. El quiste dentígero aparece principalmente en las tres primeras décadas de vida, con crecimiento lento y asintomático. Los terceros molares,así como dientes supernumerarios, pueden estar relacionados con su formación, sin embargo, su etiopatología no es totalmente conocida. La descompresión, marsupialización y la enucleación son las principales formas de tratamiento, pero algunos criterios deben ser considerados, como tamaño del quiste, edad del paciente, proximidad con estructuras anatómicas nobles e importancia clínica del diente involucrado. Para que se establezca un correcto diagnóstico y plan de tratamiento es esencial la utilización de exámenes complementarios de calidad, siendo, actualmente, la tomografía computarizada de haz cónico el más completo y preciso método de diagnóstico por imagen empleado en estas lesiones. El objetivo de este estudio fue resaltar, por medio de la presentación de un caso clínico, la importancia de la tomografía computarizada de haz cónico en el diagnóstico y planeamiento quirúrgico de un quiste dentígero asociado a un diente no erupcionado

The dentigerous cyst is one of the most frequently found in the jaws. They present themselves radiographically as radiolucent images and more commonly unilocular. They are usually observed at routine checkups or when investigating the presence of unerupted teeth. The dentigerous cyst occurs mainly in the first three decades of life, their growth is slow and asymptomatic. The third molars, as well as supernumerary teeth may be involved with the formation of a dentigerous cyst, but its pathogenesis is still not fully known. Decompression, marsupialization and enucleation are the main forms of treatment, but some criteria must be considered for the treatment plan, such as cyst size, age, proximity to noble anatomical structures and clinical importance of the tooth involved.In order to establish a correct diagnosis and treatment plan is essential to make use of complementary exams and now a days the cone beam computed tomography is the most complete and accurate method in diagnostic imaging used in these situations. Therefore, the aim of this study was to highlight, through the presentation of a clinical case, the importance of cone beam computed tomography in the diagnosis and treatment planning of a dentigerous cyst

Is radiographic appearance a reliable indicator for the absence or presence of pathology in impacted third molars.

In dental practice, impacted third molar teeth are a common finding. The dentists usually remove them if they are associated with some radiographic finding suggestive of a cyst or a tumor or if they cause pain or resorption of the adjacent teeth. It has been found that, in many cases, even the radiographically and clinically asymptomatic impacted mandibular third molars are associated with some pathology. This paper brings into the light two cases with clinically and radiographically normal impacted third molar teeth associated with dentigerous cyst, thus highlighting that the radiographic appearance is not a reliable indicator of the absence or presence of pathology associated with the impacted third molars.

Quiste dentígeno gigante en una niña: presentación de un caso / Giant dentigerous cyst in a girl: case report

After carrying out laboratory exams, radiographic studies and computerized axial tomography (TAC), she was taken to the operating room to receive an extraction of the third left superior molar retained in inverted position, and to have retrieved the extensive rays- X radiolucid and radiopaque area at tomography and later on she underwent a histopathological study. The definitive diagnosis corroborated the presumption of dentition cyst. The patient evolved in an excellent way; her facial deformity and other preoperative symptoms disappeared(AU)

Clinical and radiological behaviour of dentigerous cyst - study

The maxillofacial region is affected by a greater number of cysts than any other part of the body. The present study [A descriptive case series] is about the clinical, features i.e. age, sex and site distribution and radiological features of dentigerous cyst performed on 47 biopsy proved cases over a period of two years. This cystic lesion is common in males [60%] as compared to females [40%]. The most common age group is the second decade [48.9%] of life. The mandibular third molar region [57.44%] is the most favorite anatomical site, followed by maxillary canine region [25.53%]. Swelling has been the most common chief complaint i.e. [61.702%]. In 19.14% of patients, dentigerous cyst was a chance radiographic finding. The most common radiological feature is a well circumscribed unilocular radiolucency surrounding the crown of a tooth [96%] modalities were enucleation [83%], marsupialization [11%] and marsupialization followed by enucleation [6%]
