“…In the present study, analogous to the research by Ladeira et al 2 and Ilguy et al 4 , CBCT was used to estimate the prevalence of pneumatizations, classifying them according to the location, which included pneumatizations restricted to the mandibular fossa roof and articular eminence pneumatization. However, in contrast to the two studies, in the present study, the joint roof was defined as the portion of the temporal bone above the horizontally drawn line from the highest point of the mandibular fossa space and is anterior to the mastoid process external auditory canal 28 . Therefore, the highest point of the articular fossa is the fixed point of the ginglymoarthrodial joint, which represents the TMJ, unlike the mandible head, if used as a reference point 28 .…”

“…However, in contrast to the two studies, in the present study, the joint roof was defined as the portion of the temporal bone above the horizontally drawn line from the highest point of the mandibular fossa space and is anterior to the mastoid process external auditory canal 28 . Therefore, the highest point of the articular fossa is the fixed point of the ginglymoarthrodial joint, which represents the TMJ, unlike the mandible head, if used as a reference point 28 . Since patients with TMJ dysfunction may have altered condylar relationships and wear, the definition of the joint roof that would correspond to the bone region of the temporal bone just above the mandible head is poorly standardized.…”

Aim: To evaluate the presence and characteristics of pneumatizations in the roof of the mandibular fossa and articular eminence by panoramic radiography and cone beam computed tomography (CBCT). Methods: This study analyzed CBCT images of the temporomandibular joint of 705 patients, In 60 exams, it was possible to compare tomographic with panoramic images. For cases where pneumatization was present, laterality and pattern of manifestation were considered. A chi-square test was used to compare the differences between CBCT and panoramic radiography in the diagnosis of pneumatization. Results: Descriptive analysis revealed a sample profile that was predominantly female (75.9%), with a mean age of 42.6 years (± 17.4). The presence of pneumatizations in the roof of the mandibular fossa and articular eminence in CBCT images was identified in 330 (46.8%) and 154 (21.8%) exams, respectively, and the most frequent pneumatization pattern was the multilocular type in both locations. Bilateral pneumatization was more prevalent in the roof of the mandibular fossa. Considering the analysis of 60 pairs of exams, in panoramic radiography, pneumatizations in the roof of the mandibular fossa and articular eminence were identified in 22 (36.7%) and 12 (20.0%) examinations, respectively. Regarding CBCT images, pneumatizations in the roof of the mandibular fossa was observed in 24 (40.0%) exams, while articular eminence was found in 14 (23.3%) images. There were no statistically significant differences between the proportion of pneumatization identified by panoramic radiography and CBCT (p > 0.05). Conclusion: This study suggests that panoramic radiography may be an imaging method used to evaluate pneumatization in the temporomandibular joint region. Uniterms: Temporal bone. Temporomandibular joint. Panoramic radiography. Cone beam computed tomography.

“…The temporomandibular joint is a collection of anatomical structures that, with the participation of special groups of muscles, allows the jaw to perform various movements during chewing [15]. Classically, it has been described as a bilateral synovial joint of the ginglymo-arthroid type, which allows rotation and displacement of the mandibular condyle [17,18] in addition to opening, closing, protrusion, retrusion and laterality movements of the mandible [19,20].…”

Background: The temporomandibular joint plays a crucial role in daily oral functions like mastication. A comprehensive understanding of the histological components of these joints proves valuable in deciphering their intricate anatomical structures. Purpose of the study: This study aimed to compare the histochemical stains of hematoxylin-eosin and Goldner's trichrome applied to a temporomandibular joint sample using the Wistar Rat as a biomodel. Results: Complete sagittal slices of murine biomodel hemicranium were evaluated and the comprehensive histological technique involved various steps, including perfusion, post-fixation, decalcification, dehydration, clarification, inclusion, cutting, staining, and assembly. The temporomandibular joint specimens were stained using H&E and Goldner's trichrome. The histological description included structures such as the external auditory canal, mandibular fossa and condyle, pterygoid muscles, joint capsule, synovial membrane, articular disc, and articular surface. Special cell types like chondrocytes and synovial cells were also identified. Conclusion: Goldner's trichrome, an underutilized technique, exhibited superior chromatic richness in differentiating the cellular and tissue components of the temporomandibular joint. KEYWORDS: histology, joint capsule, synovial membrane, temporomandibular joint, temporomandibular joint disc, trichrome stain, Wistar rats.

“…Esta se encuentra acompañada por el menisco o disco articular, ligamentos, cápsula articular y los músculos periarticulares (1) . Es una de las articulaciones con más complejidad en el cuerpo humano, permitiendo los movimientos de apertura, cierre, protrusión, retrusión y lateralidad de la mandíbula, influenciados por los músculos de la masticación (2,3) . Se clasifica como una articulación diartrodia, sinovial, bicondílea y multiaxial, ya que se enfrenta el cóndilo de la mandíbula con el cóndilo del temporal, pero se comporta como una articulación de encaje recíproco cuando el cóndilo está en la cavidad glenoidea.…”

Describir sobre la base de disecciones de piezas anatómicas, los componentes anatómicos del Complejo Articular Cràneo-Mandibular (CACM). Materiales y métodos: Se utilizaron 08 hemicabezas de preparados anatómicos pertenecientes a adultos humanos venezolanos, tratados previamente con formol al 10% y conservados en Gerdex ® sin diluir durante 6 meses, previo a la práctica manual. Consecutivamente, se disecaron los elementos siguiendo el protocolo de la Facultad de Odontología de la Universidad de los Andes y se particularizaron las piezas anatómicas con la finalidad de abordar la diferente naturaleza de los elementos que conforman el CACM. Resultados: La disección anatómica logró contrastar lo referido desde el punto de vista teórico con relación a lo que puede evidenciarse en una intervención quirúrgica, ilustrando el contenido anatómico que la misma posee en condiciones de normalidad. Los elementos del CACM en su mayoría coinciden notablemente con lo descrito en esta investigación; por lo tanto, el conocimiento concreto de estos componentes permite una preparación previa para evitar cualquier complicación o alteración de las condiciones anatómicas de estas estructuras. Conclusiones: Al aplicar esta técnica se contribuyó en el campo investigativo a ampliar el proceso de aprendizaje anatómico teórico-práctico para los profesionales de la Odontología.
