RESUMO
OBJECTIVE: The aim: To analyze modern research methods that allow to determine the features of the position of the tongue during the functions of swallowing and speech. PATIENTS AND METHODS: Materials and methods: An analysis of 37 literature sources, which contains information about the methods of examination of patients with dento-maxillar anomalies. CONCLUSION: Conclusions: The functions of the tongue (swallowing and speaking) are very complex and coordinated movements that require the activation of many anatomical structures. Therefore, the disorders of the tongue during swallowing and speech are still considered by scientists as the most difficult in terms of correction and achieving of the long-term and stable results of orthodontic treatment. The study of modern trends in the diagnosis of the state of language functions in terms of understanding the functioning of the dental-maxillary area as a masticatory organ, the work and condition of the components of which depend on many systems of the human body, is relevant. Thus, the emergence of new and modifications of existing research methods undoubtedly expand the capabilities of modern orthodontists. However, this does not reduce the importance of the clinical stage of examination of patients with disorders of the maxillofacial area, including the functions of the tongue. Therefore, it is necessary to know and understand the advantages and disadvantages of modern and existing research technologies, which will allow to choose a communicatively integrated and differentiated approach to diagnostic issues in each clinical case.
