Por qué importa

Un estudio reciente publicado en el Journal of Oral & Maxillofacial Research explora la fascinante relación entre la oclusión dental y la anatomía cerebral. La investigación analizó a 70 pacientes, correlacionando el número de pares oclusales funcionales con cambios volumétricos en la sustancia blanca y gris, así como en el grosor de la corteza cerebral, medidos mediante resonancia magnética. Los hallazgos sugieren que un menor número de contactos oclusales funcionales se asocia con reducciones en áreas cerebrales específicas. Esta conexión, aunque compleja, subraya la importancia de mantener una oclusión adecuada, ya que las regiones cerebrales afectadas están implicadas en procesos neurodegenerativos como el alzhéimer. Para el odontólogo, esto refuerza el papel de la salud bucal en el bienestar general del paciente.

Abstract original

Objectives: The purpose of this observational clinical study was to evaluate the relationship between brain anatomical and volumetric changes in white matter, grey matter, and cerebral cortex thickness with the number of functional occlusal pairs present in the mouth. Material and Methods: The number of functional occlusal pairs in 70 patients was counted and non-invasive brain analysis was performed using magnetic resonance imaging. The volume of grey matter, white matter, and thickness of the cortex in different areas of the brain were determined by SPM12 and CAT12 software. Multiple regression model corrected for multiple comparisons using FDR and Spearman correlation coefficient were calculated for statistical comparison. Results: A total of 70 (39 male, 31 female) were analysed, with an average number of occlusal pairs of 10.21 (3.99). According to the Spearman correlation coefficient, a lower number of occlusal pairs was related to a reduction in white matter (right external capsule and posterior limb of the internal capsule), a reduction in grey matter (right temporal superior and medial gyrus and left cerebellum crus 1) and a reduction in thickness of the cerebral cortex (rostral anterior cingulated cortex of the right hemisphere and areas in the right and left hemisphere, especially in the frontal cortex). Conclusions: The number of occlusal pairs is related to the volume of white matter, grey matter, and thickness of the cerebral cortex in areas of the brain that are directly involved in the onset and progression of Alzheimer's disease and other dementias.
