Enhancing cognition and well-being by treating the malocclusion unilateral posterior crossbite: preliminary evidence by a single case study.

Scientific investigations have increasingly revealed the intricate connection between masticatory function and cognitive functioning, as well as psychological well-being. Addressing malocclusions, such as the common unilateral posterior crossbite, during early developmental stages, emerges as an effective strategy for gaining health. This study aims to evaluate the efficacy of treating unilateral posterior crossbite by utilizing a function generating bite (FGB) appliance in a 12-year-old child, focusing on its impact on specific cognitive domains. Through meticulous pre- and post-treatment assessments, encompassing global cognitive activity (Colored Progressive Matrices), verbal and spatial working memory (Digit Span and Corsi Block-Tapping Test), and graphic fluency (modified Five Points Test), this research aims to elucidate the cognitive benefits associated with FGB treatment. Results unveil that a mere seven-month application of FGB effectively rectified the malocclusion while concurrently yielding notable improvements in the cognitive abilities under scrutiny. Additionally, post-treatment observations revealed enhanced well-being and sleep quality, further emphasizing the multifaceted benefits of such interventions. Although this study presents findings from a singular case, it serves as a catalyst for further exploration into the intricate interplay between masticatory function and cognitive performance. Such endeavors are vital for advancing holistic healthcare practices that integrate dental care with cognitive and psychological considerations, thereby fostering comprehensive well-being and optimal development.
