Radiological study of impacted third mandibular molars in relationship with mylohyoid canal: a case report
The aim of this study was to present a case report through which to demonstrate cone beam computed tomography advantages in impacted mandibular third molars presurgical study. A case of 47-year-old man with a semi/impacted mandibular third molar for surgical removal was reported. Cone beam computed...

Fernández et al Diagnostic imaging, impacted tooth, cone bema computed tomography diagnóstico por imágenes, diente retenido, cone beam The aim of this study was to present a case report through which to demonstrate cone beam computed tomography advantages in impacted mandibular third molars presurgical study. A case of 47-year-old man with a semi/impacted mandibular third molar for surgical removal was reported. Cone beam computed tomography study was made with Promax-3D plus unit. Obteined images were observed and analized by Romexis software 4.4.0.R. In obliques views, third molar presence in very deep and lingual position was verified. Inferior alveolar canal was visualized as a hypodense ovoidal region surrounded by a continuous hyperdense halo and separated from root tooth by 2.80 mm. 3D reconstruction allowed to visualize an intimate contiguous relationship with mylohyoid canal. Impacted mandibular third molar extraction is a commonly performed procedure in dental practice thereby dento-maxillo-facial surgeon must analyze all anatomical details of radiological images. In complex cases, specific studies such as CBCT, which turned out to be the gold standard for pre-surgical diagnosis and planning, should be requested and thus avoid complications that can occur in these surgeries. New and current evidence-based recommendations advocate that cone beam computed tomography study should be performed only when 2D radiological techniques do not provide surgeon with sufficient and accurate information and not as a routine protocol before mandibular third molars surgical removal. El objetivo del presente trabajo fue presentar un caso clínico a través del cual se evidenciaron las ventajas del uso de la Tomografía Computada Cone Beam en el estudio prequirúrgico de 3° molares mandibulares retenidos en íntima relación con el canal milohioideo. Se presenta el caso de un paciente masculino de 47 años que acude a la consulta para la extracción de un tercer molar mandibular derecho semirretenido. Se realizó una Tomografía Computada Cone Beam con el equipo Promax-3D plus. Las imágenes obtenidas fueron visualizadas y analizadas con el software Romexis 4.4.0.R. En los cortes oblicuos se comprobó la presencia del 3° molar en posición profunda y hacia lingual. El canal alveolar inferior se visualizó como una zona hipodensa de sección ovoidal, rodeado por un halo hiperdenso continuo y separada 2,80 mm de la raíz del diente retenido. El renderizado 3D permitió visualizar una íntima relación con el canal milohioideo. Siendo la extirpación del 3° molar mandibular retenido una práctica quirúrgica frecuente, el cirujano buco-maxilo-facial deberá analizar minuciosamente cada detalle anatómico de las imágenes radiológicas. En casos complejos se deberán solicitar estudios específicos como la TCCB que resultó ser el “gold standard” para el diagnóstico y planificación prequirúrgicos y así evitar las complicaciones que pueden producirse en estas cirugías. Las nuevas y actuales recomendaciones basadas en la evidencia aconsejan que la Tomografía Computada Cone Beam debe realizarse sólo cuando las técnicas radiológicas 2D no proporcionen al cirujano información suficiente y precisa y no como un protocolo radiológico de rutina para la extracción del 3° molar mandibular retenido Facultad de Odontología 2020-08-21 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://revistas.unc.edu.ar/index.php/RevFacOdonto/article/view/29989 Revista de la Facultad de Odontología; Vol. 30 Núm. 2 (2020): VOL 30 NUM 2 AÑO 2020; 28-33 2545-7594 0325-1071 spa https://revistas.unc.edu.ar/index.php/RevFacOdonto/article/view/29989/30745 https://creativecommons.org/licenses/by-nc-sa/4.0 |
