| Abstract: | Background: Anterior open bite (AOB) affects 16.5% of children aged 2-16 years, significantly impacting dental occlusion and oral function. Among various contributing factors, improper tongue posture has been implicated. This study aims to assess neuronal cortical activation differences in children with AOB compared to those without, focusing on rest, speech and swallowing disorders. Objective: To compare the prevalence of articulation disorders, swallowing occurrences, tongue rate of motion ratio, and brain activation patterns at rest and during deglutition and phonation in children with and without AOB. Materials and Methods: This case-control study involved 33 children aged 8 to 11 years, divided into two groups: 16 with AOB and 17 without. Clinical assessments for AOB, articulation testing, evaluation of swallowing frequency, and Quantitative Electroencephalography (QEEG) for brain activity analysis were conducted. Statistical comparisons were made using T-student tests and Mann-Whitney tests where appropriate. Results: Children with AOB displayed a significantly higher incidence of articulation disorders (p = 0.03) and greater swallowing occurrences (mean 2.3 vs. 1.5, p = 0.02) compared to the No AOB group. QEEG results revealed higher Theta/Beta ratios (p<0.05) in the central sulcus area at rest and significantly lower Beta frequency during swallowing and phonation in the AOB group. Conclusion: The study reveals significant differences in articulation, swallowing frequency, and brain activation patterns related to AOB, highlighting its detrimental impact on neurophysiological functions. These findings underscore the necessity for transdisciplinary collaboration between dentistry and speech pathology to address the complex repercussions of AOB in children. |
