What is already known on this subject Anterior open bite (AOB) has been identified as a malocclusion associated with various developmental issues, including speech and swallowing disorders in children. A prior pilot study has suggested altered activity of the brain cortex during rest. However, a structured diagnosis of articulation disorders and swallowing and its relationship with brain activity has not been performed before. What this study adds to existing knowledge This investigation provides new insights into the neurophysiological differences between children with AOB and those without, particularly concerning articulation disorders and swallowing occurrences. The findings reveal that children with AOB exhibit not only a higher prevalence of speech articulatory disorders, but also distinct brain activation patterns during rest and functional tasks, particularly involving the central sulcus. This study advances the understanding of the interplay between dental occlusions and neural processes, suggesting a need for integrated approaches in managing paediatric AOB. What are the potential or actual clinical implications of this study? The results underscore the importance of transdisciplinary collaborations between dental and speech therapy professionals when addressing AOB in children to achieve comprehensive management. By recognizing the neurophysiological implications of AOB on speech and swallowing, clinicians can tailor interventions more effectively, potentially improving outcomes in children affected by this malocclusion. Additionally, the assessment of brain activity may prompt further exploration of underlying cognitive concerns, enabling early identification and intervention for related disorders.
