Resumen

La tomografía computarizada de haz cónico es un examen diagnóstico que utiliza un scanner para obtener imágenes en tercera dimensión, los parámetros más relevantes que se deben tener en cuenta en el equipo son: el tamaño del campo visual, tiempo de exposición, voltaje de corriente del tubo y grados de rotación del cabezote alrededor del paciente. Esta técnica permite observar imágenes en tres planos, reduciendo la superposición de estructuras anatómicas, identificando con detalle la morfología interna del diente, alteraciones como perforaciones, zonas de reabsorción, lesiones periapicales, fracturas radiculares y la identificación de lesiones de origen no odontogénico. Entre sus desventajas se encuentra resolución espacial baja, dispersión y endurecimiento del haz por la presencia de estructuras metálicas como coronas, implantes y núcleos intrarradiculares. Es importante resaltar que una imagen en tres dimensiones brinda mayor fiabilidad y seguridad para el diagnóstico, tratamiento y pronóstico del tratamiento de endodoncia.
