The review of the general literature devoted to the prediction of the results of dental anomaly orthodontic treatment was carried out. An effective tool for reliable stage and result planning of orthodontic treatment is the creation of a software system contributing to individual approach as well as taking into account many factors that influence the etiopathogenesis of dental anomalies. On the background of studying the dynamics of changes in chronic gingivitis during orthodontic treatment, a protocol was developed for constructing a mathematical model for creating software which can be used for implementing personalized treatment approach.

Supernumerary teeth are one of the dental anomalies which occur due to the developmental disturbances in teeth. They can be seen in various shape and form. They can occur in both the deciduous and permanent dentition and can impose aesthetic and occlusion problems. Morphologically the supernumerary teeth exhibit various forms ranging from conical to tuberculate and supplemental types. Supplemental teeth as the name suggests are similar in shape to that of the normal prototype. In this particular case, we are reporting a case of ipsilateral supplemental permanent lateral incisors and the treatment approach which would subsequently facilitate the patient to undergo orthodontic treatment.

The creation of information models requires the use of known methods and the development of new methods of formalizing the pre-design research process. The modeling process consists of four stages: data collection on the object of management - pre-project research; creation of a graphical model of business processes taking place in the enterprise; development of a formal model of business processes; business research by optimizing the formal model. To support the creation of workflow management services and systems, the complex offers methodologies, standards and specialized software that make up the developer's tools. This can be ensured only by modern automated methods based on information systems. It is important that the information collected is structured to meet the needs of potential users and stored in a form that allows the use of modern access technologies. Before discussing the effectiveness of FIM, it should be noted that the basic concept of information itself is still not the same. In a pragmatic way, it is a set of messages in the form of an important document for the system. Information can be evaluated not only by volume, but also by various parameters, the most important of which are: timeliness, relevance, value, aging, accuracy, etc. in addition, the information may be clear, probable and accurate. The methods of its reception and processing are different in each case.

Background: Hypodontia is one of the most common anomalies in dentistry. Hypodontia has a negative impact on oral health-related quality of life with patients best seen in a multidisciplinary clinic to improve treatment outcomes. Aim: To investigate the prevalence of hypodontia and its association with other dental anomalies, as well as malocclusion, and to investigate the treatment planned for patients attending the clinic and whether the type of missing teeth affected the proposed treatment. Materials and Methods: Analysis of consecutive patients attending the hypodontia clinic at a dental hospital between February and November 2020. A total of 100 patients who met the inclusion criteria were identified. Data collected included the following: age/sex; number and type of missing teeth; pre-treatment occlusion; presence of other dental anomalies; and planned treatment. Results: A total of 100 patients (55% female; age range = 7–41 years; mean age = 18 years) were included. Of the cohort, 47% had a class I skeletal relationship and participants were significantly less likely to have a class III skeletal or incisor relationship; 45% had another dental anomaly with the most common being microdontia. Space opening was the preferred treatment option for those managed by orthodontic treatment with resin-bonded bridges most likely to be used for restoration of spaces, 86%. Conclusion: Lower second premolars were the most commonly missing teeth. Participants were significantly less likely to have a class III incisor or skeletal relationship than class I or II. Space opening was the favoured approach for orthodontic treatment, particularly for maxillary lateral incisors.

This paper presents results obtained between 2010 and 2014 in the field of fan aerodynamics at the Department of Composite Technology at the VZLÚ aerospace research and experimental institute in Prague – Letnany. The need for rapid and accurate methods for the preliminary design of blade machinery led to the creation of a mathematical model based on the basic laws of turbomachine aerodynamics. The mathematical model, the derivation of which is briefly described below, has been encoded in a computer programme, which enables the theoretical characteristics of a fan of the designed geometry to be determined rapidly. The validity of the mathematical model is assessed continuously by measuring model fans in the measuring unit, which was developed and manufactured specifically for this purpose. The paper also presents a comparison between measured characteristics and characteristics determined by the mathematical model as the basis for a discussion on possible causes of measured deviations and calculation deviations.

The purpose of the research is to increase the level of security of electronic document metadata in the face of destructive influences from authorized users (insiders). Research methods: new scientific results allowed using a combination of data integrity control method based on the «write once» method and of authentication of HMAС messages (hash-based message authentication, as well as graph theory methods. Research result: a method of cryptographic recursive 2-D control of the integrity of electronic documents metadata is proposed. The analysis of the object of the study was carried out, based on the results of which it was concluded that it is necessary to effectively protect the metadata of electronic documents processed by automated information systems of electronic document management. Developed and described a mathematical model of the proposed method, based on graph theory. The developed technical solution makes it possible to implement the functions of cryptographic recursive twodimensional control of the integrity of the metadata of electronic documents, as well as to provide the possibility of localizing modified (with signs of violation of integrity) metadata records, in conditions of destructive influences of authorized users (insiders). This, in turn, reduces the likelihood of collusion between trusted parties by introducing mutual control over the results of their actions. The proposed solution makes it possible to ensure control of the integrity of data processed by departmental automated information systems of electronic document management, where, due to the peculiarities of their construction, it is impossible to effectively use the currently popular blockchain technology.

The green information systems (green IS) address the demand for information about green spaces in both urban and non-urbanized areas. This systems are part of green infrastructure (GI) and National Spatial Data Infrastructure (NSDI). GI are very important for the urban environment, and it improves the quality of life. There are various types of urban greenery. The green IS can support the management, maintenance, monitoring, protection and revitalization of urban greenery and all GI. This systems contribute to the sustainable development of urban areas, the development of smart and green cities and spatially enabled societies where community members are involved in local projects. In Poland, few cities have so far taken the effort to create a green IS due to the costs of starting and maintaining the system. Municipalities give up the creation of this system because it is not a good first necessity. However, green infrastructure is developing in Poland and there is a strong demand for green IS for easier GI management. Therefore, the aim of the research was to identify various determinants (factors) that may affect the development of green IS in Poland. Analysisof determinants is necessary and important from the point of view of knowledge of mechanisms affecting the development of green IS and may be useful to develop a strategy for further activities promoting the creation of green IS in all cities in Poland. The research results provided the basis for distinguishing groups of impact factors due to their specificity and showed which instruments are applied to them taking into account global and local initiatives.

One of the rapidly developing research areas is the creation of systems. which are commonly referred to as cyberphysical complexes. In such systems, devices and complexes interact with a completely different physical nature. The role of a person in such systems usually consists in the formation of final tasks for “artificial intelligence” and executive mechanisms. The functioning of actuators is controlled by accurate information systems.

Introduction. The influence of the dental apparatus on the balance of the body in an upright position has been widely discussed in the literature for several decades. Examination of the patient taking into account his postural balance makes it possible to clarify the reasons for the low effectiveness of pain syndromes treatment of the craniocervical region caused by malocclusion, as well as ineffective correction of musculoskeletal dysfunction of the temporomandibular joint (MSD TMJ) associated with posture disorders.The aim of the study is to evaluate the effectiveness of treatment of patients with dental anomalies and musculoskeletal dysfunctions of the temporomandibular joint and concomitant somatic dysfunctions (if any) by methods of orthodontic and osteopathic correction.Materials and methods. The study involved 102 patients aged from 18 to 45 years with TMJ. All patients underwent orthodontic and osteopathic examination. 3 groups of patients were formed: № 1 — exclusively with dental anomalies TMJ (occlusive dysfunction), who received only orthodontic treatment, № 2 with concomitant somatic (extra-occlusive) dysfunctions, who received only orthodontic treatment, and №3 with concomitant somatic (extra-occlusive) dysfunctions, who received both orthodontic and osteopathic treatment. Orthodontic treatment of musculoskeletal dysfunction of the TMJ consisted of the occlusive kappa manufacturing. Osteopathic correction was carried out individually, taking into account the identified somatic dysfunctions, on average 3 sessions. Patients also received drug therapy, and they performed myohymnastics for the masticatory muscles. The clinical dysfunction index (Helkimo M.) was used to control the elimination dynamics of the TMJ's musculoskeletal dysfunction symptoms. The assessment of the pain dynamics in the TMJ was carried out by a visual-analog scale (VAS). The evaluation of the osteopathic treatment effectiveness was carried out on the basis of computer stabilometry data and osteopathic examination data. A stabilometric study was performed on the «ST-150» («Biomera») stabiloplatform in the Romberg sample (European foot installation) with open and closed eyes in two positions of the lower jaw: 1) in a state of physiological rest (tooth rows are separated); 2) in the kappa with closed tooth rows.Results. The MSD TMJ symptoms were eliminated 10 weeks after the start of treatment in all (100 %) patients of group № 1 and group № 3. Among the patients in group № 2, only 12,1 % of patients had complete absence of MSD TMJ symptoms, while all patients in this group had a statistically significant decrease in the clinical index of Helkimo dysfunction. In one third of the group № 2 patients on the 12th week of orthodontic treatment, headaches and/or pains in other parts of the musculoskeletal system (neck, back, shoulders, arms) prevailed among complaints and which were previously indicated in the anamnesis. This occurred after the elimination of the MSD TMJ symptoms. The absolute majority of patients in group № 3 (97,1 %) noted the complete disappearance of headaches and/or pains in other parts of the musculoskeletal system (neck, back, shoulders, arms). Also, in patients of this group, stabilometric indicators were normalized in a state of physiological rest and in the kappa.Conclusion. Patients with somatic dysfunctions need complex treatment with the participation of an osteopath and a dentist. When assessing the osteopathic status of a patient, it is important to determine whether the patient has only occlusive dysfunctions or there are also extra-occlusive ones. Additional osteopathic correction is recommended for patients with extraocclusive dysfunctions in order to achieve treatment results comparable in effectiveness and timing.
