Predicción del tercer molar e indicaciones de germenectomía: reporte de un caso / Prediction of the third molar and indications of germectomy: report of a case

Los factores ambientales y evolutivos, los cambios en los hábitos dietéticos, entre otros, pueden desencadenar un papel etiológico en la aparición de anomalías dentales llevando a la especie humana a una disminución en la función masticatoria que trae como consecuencia una reducción en el tamaño de los maxilares originando la falta de espacio para la correcta posición de los dientes en el arco dental, lo que provoca un aumento en la incidencia de casos de segundos y terceros molares retenidos con su consecuente patología multisintomática ocasionando de esta manera un problema de salud pública. Diversos autores han utilizado las imágenes radiográficas para realizar análisis específicamente del tercer molar, basándose en una proyección lateral y panorámica para, mediante marcas y referencias, establecer un diagnóstico y determinar el riesgo y la necesidad de su extracción. La imagenología presenta una nueva herramienta que es la tomografía Cone Beam que nos permite adaptar los conocimientos clásicos del análisis del tercer molar a una imagen en tres dimensiones, aportando el factor profundidad (AU)

Environmental factors, evolutionary changes in dietary habits, among others can trigger an etiological role in the appearance of dental anomalies. Taking the human species to a decrease in masticatory function resulting in a reduction in the size of the jaws, resulting in a lack of space for the correct position of the teeth in the dental arch. Causing an increase in the incidence of second and third molars retained. Its eruption restriction consequent multisymptomatic pathology causing a public health problem in this way. Several authors have used the radiographic images to perform analyzes of the third molar. Based on a lateral and a panoramic radiographic projection, to establish a diagnosis and determine the risk and the need to extract it. Imaging diagnostic presents a new tool that is Cone Beam tomography that allows us to adapt the classical knowledge of the third molar analysis to an image in three dimensions, providing the depth factor (AU)

Remoção de terceiro molar superior deslocado para o espaço bucal / Removal of upper third molar displaced to the buccal space

Os autores descrevem um caso clínico de deslocamento de germe dentário de terceiro molar superior esquerdo para o espaço bucal em um paciente de 13 anos de idade. A localização do dente em posição profunda com envolvimento do corpo adiposo do bucinador dificultou a sua localização, ainda não descrita, nas condições em questão, na literatura. Com a Tomografia Computadorizada de Feixe Cônico (TCFC), foi possível localizar o dente deslocado e planejar a sua remoção. Os riscos e benefícios das extrações de germes de terceiros molares precisam ser avaliados devido ao grande risco de deslocamentos... (AU)

The authors describe a case of displacement of left upper third molar tooth germ to the buccal space in a patient 13 years old. The deep position of the tooth with involvement of the fat body of the buccinator made it difficult its location, still not described, under the concerned conditions, in the literature. With the cone beam computed tomography (CBCT), it was possible determine the location of the tooth and plan his removal. The risks and benefits of third molar tooth germ extraction should be evaluated because there is a greater chance of displacement... (AU)

Bilateral lower second molar impaction in teenagers: An emergent problem.

The frequency of simultaneously impacted second and third molars in teenagers is increasing and becoming a common occurrence in adolescent oral surgery practice. The traditional treatment is the removal of the third molar by conventional access but repositioning of the surgical flap to the distal face of the first molar can predispose to complications such as pericoronitis and delayed healing of the attached gingiva. We present a case in which we use the germectomy approach to remove the impacted third molar for the eruption of the second molar through a vestibular incision. This incision offers excellent bone exposure and exit route for the third molar without disturbing the gingiva attached architecture on the distal face of the first molar providing good healing environment.
