Currently, there is a tendency in Ukraine to increase the number of children with speech disorders. One of the most common disorders of speech function is dyslalia. Speech therapists are the main form of correctional training, children are assigned certain and consistent stages of speech therapy. Along with that, various individual and standard devices are used. The aim of the study – to conduct logopedic correction of speech disorders in patients with physiologic occlusion using the in-house designed device according to the proposed algorithm. Materials and Methods. A survey was conducted on 73 children (24 – aged 3 to 6 years, 49 – from 6 to 12 years old) without significant orthodontic pathology in the presence of speech impairment with normal hearing and intelligence and speech correction. In addition to logopedic exercises, it was recommended to use vestibular plates Dr. Hinz - MUPPY-P with beads, removable orthodontic devices with beads, Bluegrass appliances, devices for elimination and prevention of unhealthy tongue habits. In order to identify early risk factors for major dental diseases, the hygienic state of the cavity of the mouth, the intensity of caries, the presence or absence of inflammatory processes in the tissues of periodontal disease were determined. Results and Discussion. The first step in the algorithm for successful correction of speech disorders were to explain its necessity. The second stage involved the phonetic diagnosis of all aspects of speech, logic, intelligence, memory and thinking. Polymorphic dyslalia was diagnosed in all subjects of reporting panel. The third stage of the algorithm is to carry out work to overcome the abnormalities of the phonetic side of speech was a direct speech correction. The proposed device for elimination and prevention of unhealthy tongue habits was used in 6 cases. Conclusions. After the speech therapy correction correct articulation and sound were formed. The proposed device for the elimination and prevention unhealthy tongue habits should be used in conjunction with speech therapy, in particular, dyslalia. In addition to the positive logopedic effect of the proposed therapeutic and prophylactic measures, we have also received improvement of the hygienic state of the oral cavity, the absence of an increase in the intensity of the caries of permanent teeth and increased motivation in patients.
The relevance of research. When examining patients with dentoalveolar anomalies, children with speech disorders can often be observed. For orthodontists, it is important to diagnose the etiologic component of these disorders, namely, whether they are the cause of diseases of the ENT-organs and whether they are directly related to orthodontic pathology. In order to study the impact of the pathology of the ENT-organs on the formation of speech disorders, clinical and additional examination methods were carried out. In case of respiratory tract narrowing due to the deviated septum, hypertrophic or allergic rhinitis, adenoid vegetations, hypertrophy of the tonsils, speech pathology may be observed. Specified pathologies are subject to treatment before the logopedic and orthodontic correction. According to our clinical study in children of the main group and of the comparison group, the apparent pathology of the nose and oropharynx was not detected. Subjective and objective methods of hearing examination also did not reveal deviations from the norm. For a more detailed study of the condition of the upper respiratory tract, it is advisable to use computer tomography of the skull and magnetic resonance therapy of the head. The purpose of research is to eliminate the influence of otorhinolaryngologic pathologies on the formation of speech disorders. Materials and methods. We examined 124 patients. Patients were divided into two groups: control and comparison. The control group consisted of 82 patients with anomalies and deformations of dentognathic apparatus and speech disorders. The comparison group consisted of 42 patients without orthodontic pathology who applied to otolaryngologists for a diagnostic examination. The examination did not show the expressed pathology of ENT-organs in the presence of speech impairment and 5 children (aged from 6 to 12 years) with ENT pathology and speech impairment were not included in the main comparison groups. To make clinical and additional diagnosis such methods as rhinoscopy, pharyngoscopy, otoscopy were used. Results and discussion. During the rhinoscopy of all the examined patients of control and comparison groups, it was found: the nasal passages were free, the nasal shells were of the usual size, the nasal membrane was in the medial position, pathological contents in the nasal cavity were not detected. During pharyngoscopy, attention was mainly paid to the size of palatine tonsils. Thus, 62 children (50%) had the 1st and 2nd stage of development, 42 (33.87%) - 2nd stage and 20 (16.13%) - II-III degree. Adenoids (nasopharyngeal tonsil) of the 1st and 2nd degree were established in 86 children (69.35%), 28 children (22.58%) - second degree and 10 (8.06%) - II-III degree, but in all children of the main and comparison groups, nasal breathing function was not noted. In 124 subjects (100%), there was no adenoid type of facial skeleton. Conclusion. With the narrowing of the respiratory tract due to a curvature of the nasal septum, hypertrophic or allergic rhinitis, adenoid vegetation, hypertrophy of the palatine tonsils, speech impairments can be observed. The specified pathologies are subject to treatment before the logopedic and orthodontic correction. According to our clinical examination of children of the main group and the groups of comparison, evident pathology of the nose and oropharynx was not detected. Subjective and objective methods of hearing examination also did not reveal deviations from the norm. For a more detailed study of the condition of the upper respiratory tract, it is advisable to use computer tomography of the skull and magnetic resonance therapy of the head.
Relevance of research. Under complex correction of speech disorders in existing orthodontic pathology, it is important to establish the causative factor, because incorrect tongue articulation, infantile type of swallowing and other bad habits can be the cause of dental and maxillary pathologies and, at the same time, speech disorders. The cause-and-effect relationship between dentoalveolar and speech disorders has been proved. Anomalies and deformations of the dentoalveolar apparatus prevent the sounds from being pronounced normally, contribute to strengthening the habits of improper articulation and complicate logopedic correction. The problem of logopedic correction of sound pronunciation should be addressed comprehensively in collaboration with an orthodontist. The purpose of the research. To treat patients with anomalies of bite and speech disorders according to the proposed algorithm. Materials and methods. To achieve study objectives, 82 patients with severe orthodontic pathology and speech disorders, with normal hearing and intellect, were accepted for treatment. Clinical examination according to the generally accepted scheme, extraoral and intraoral photographs, anthropometry, myography, cephalometry, and logopedic diagnostics of all aspects of speech were conducted. After establishing the diagnosis, determining the treatment plan, orthodontic treatment was performed simultaneously with speech therapy correction. Results and discussion. The first step in the algorithm of successful treatment (correction) of speech disorders and dentoalveolar anomalies was the explanation of its necessity. The second stage of the algorithm was a clinical examination, which included medical history taking and objective methods of examination. The speech therapy part of the algorithm provided for speech therapy diagnosis of all aspects of speech: sound pronunciation, vocabulary, grammar, phonetics. Additional methods of examination were performed for the preparation of the plan, the choice of method and tactics of treatment: extraoral and intraoral photographs, anthropometry, myography, cephalometry, which is an integral part of the second stage of the treatment algorithm for patients with abnormalities and deformations of the dentoalveolar device in conjunction with correction of speech disorders. The third stage of the algorithm was direct orthodontic treatment and speech correction. The retention period is the final stage of the algorithm for treating patients with abnormalities and deformations of the dental apparatus in combination with the correction of speech disorders. Conclusion. The algorithm for treating patients with anomalies of bite and speech disorders consists of the following blocks: motivation, detailed diagnosis, treatment planning and tactics, the active period of orthodontic treatment simultaneously with speech correction and patient management in the retention period.
The substantiation of the current task of modern dentistry is presented, which consists of increasing the effectiveness of the treatment of dentognathic deformations accompanied by phonetic disorders through a multidisciplinary approach to the development and application of a complex of diagnostic and therapeutic measures based on the determined and clarified etiopathogenetic connections of dentognathic deformations with phonetic disorders, and causal mechanisms of the development of dentognathic deformations in cleft lip and palate and the importance of anatomic and morphometric characteristics of the tongue as a prognostic indicator of an effective orthodontic treatment as well are substantiated.
The article is devoted to the study of the impulse response function, its estimation and properties, square-Gaussian random variables and processes, the rate of convergence of the unknown impulse response function, testing the hypothesis about the type of impulse response function, building a simulation model. The study showed that the pulse response function is the output signal of the system during signal processing, when the input signal is a short pulse. In a more general form, the impulse response function describes the response or output of the system as a function of time. Also, the impulse response function is considered a property of linear displacement systems. During the study of the estimation of the impulse response function on orthonormal and trigonometric bases, two conditions A, B and remarks to them were formed, which are used in the future to find different coefficients. The study of square-Gaussian random variables and processes has shown the benefits of using them in relation to the impulse response function. A theorem was also presented, which estimated the probability of a large deviation of the square-Gaussian process in the norm of a continuous function. To study the rate of convergence of the unknown impulse response function in the space of continuous functions and in the space L2, a lemma was formed, as well as a theorem that directly showed the rate of convergence of the impulse response function in the space of continuous functions. Zero and alternative hypotheses were formed. The null hypothesis claimed that the impulse response function existed, and the alternative hypothesis suggested the opposite. To test the hypothesis about the form of the impulse response function, a theorem was used by which a criterion was formed. Visual Studio Community 2022 integrated development environment (C ++ programming language) and Wolfram Mathematica computer algebra system for analytical transformations and numerical calculations were used to build the simulation model, which allowed to make mathematical calculations quite accurately.
