Introduction. An actual problem of modern dentistry is the anomalies of the position of the lower jaw. The share of these diseases in the structure of requests for dental care can reach up to 27%. The most common pathology is distal occlusion, which accounts for 25 to 37% of all occlusion abnormalities. The aim of this work was to describe and demonstrate on a clinical example the method of orthopedic treatment of patients with distal occlusion proposed by the authors. Material and methods of research. The paper presents a new method of orthopedic treatment of patients with distal occlusion using a deprogrammer of the original design. Orthopedic treatment of patients was carried out on the basis of a multidisciplinary clinic of Postnikov in the city of Samara. Using the method proposed by the authors, orthopaedic treatment was performed in 36 patients with distal occlusion. For clarity, the article considers an original clinical case of treatment of a patient with distal occlusion, who was made a deprogrammer of the author's design, with a detailed analysis of each stage of diagnosis and orthopedic treatment. To confirm the effectiveness of the proposed technique, a CT scan of the patient's temporomandibular joint was performed before and after orthopedic treatment. As a result of the treatment, the patient has a decrease in the hypertonicity of the masticatory muscles, which made it possible to position the lower jaw in the position of the central ratio, which is confirmed by CT data. Conclusion. The use of a deprogrammer-mouthguard, the proposed design allows for deprogramming of the masticatory muscles and correctly determining the central ratio of the jaws, and can be used in the treatment of patients with distal occlusion.

This study was conducted to investigate two clinical types of masticatory muscles parafunction: teeth compression and teeth grinding using clinical and functional methods. Teeth compression and teeth grinding were found to have a common tooth compression symptom. Our finding has been proven not only through clinical, yet via electromyographic and axiographic research methods as well. Based on the obtained data we developed a palatal plate-occlusal guard. It enables to fix reliably the lower jaw and reduces muscle tension. The proposed appliance helps prevent possible complications that occur in the course of orthopedic treatment.

The study of masticatory muscles allows timely detection of changes in their functional state, as well as to identify borderline pathological processes that can lead to the development of morphological and functional disorders in the maxillofacial region. This work was carried out in order to determine changes in the functional state of the masticatory muscles in patients with de-fects in the dentition in the lateral region before and after the orthopedic treatment. To achieve this goal, an electromyographic study of the masticatory muscles was performed in 95 patients with uni-lateral and bilateral defects of the dentition in the lateral region before and after restoration of the occlusal relationship of the dentition. As a result of the examination, pronounced malfunctions of the masticatory muscles were revealed in patients with defects in the dentition. After orthopedic treatment, a restoration of the balanced functioning of the muscular system of the maxillofacial re-gion was noted.

Fractures are one of the most common components in multiple and associated injuries. Fractures of the lower jaw are observed in 76%, of the upper jaw in 24%, a fracture of the zygomatic-orbital complex in 12%. The actual problem of modern traumatology is the violation of reparative osteogenesis with injuries combined with facial trauma. The duration of the consolidation of fractures is determined by the degree of microcirculation disorders in the fracture zone, changes in cellular and coagulation hemostasis and mineral metabolism. In this connection, increasing the effectiveness of treatment of fractures of the bones of the face on the basis of early diagnosis of vascular and hemostasiological changes is of great importance for practical health care.

Introduction. Facial asymmetries associated with lateral displacement of the jaw arise due to various reasons, namely, the presence of functional lateral displacement of the lower jaw, skeletal asymmetry of the maxillofacial region, and a combination of the above factors. Purpose. Identification of the etiological factor makes it possible to assess the possibility of correcting the position of the lower jaw and improving the relationship of the intra-articular structures of the temporomandibular joint. Materials and methods. Functional lateral displacement of the lower jaw is characterized by an asymmetric tone of the masticatory muscles, a change in the position of the chin, and dysfunction of the temporomandibular joint on the side of the displacement of the lower jaw. The article discusses a clinical case of a patient with pathology of the temporomandibular joint associated with functional displacement of the mandible. Comparison of the data of cone-beam computed tomography of the lower jaw at the site of attachment of the masticatory muscle before and after the elimination of the asymmetry of the maxillofacial region was carried out. Conclusion. An asymmetric change in the displacement of the condyles was obtained according to the data of electronic axiography, an improvement in the ratio of intra-articular structures, the presence of a change when comparing STL models of the lower jaw.

The article presents a scientific overview of the literature on the actual problem restorative dentistry: preparation low-supple atrophied tissue prosthetic bed before the prosthesis patients with complete absence of teeth in the lower jaw. Despite significant progress in prosthetic dentistry, the problem of prosthesis patients with complete absence of teeth on the lower jaw does not lose its relevance. From 15 to 46% of patients aged 45-70 years, need to manufacture complete dentures. One of the factors that directly affect the fixation of complete removable lamellar denture for the lower jaw is a condition of the mucous membrane of prosthetic bed. The most unfavorable for prosthetics full removable laminar dentures is considered as grade 2 mucosa classification Supple. This class is characterized by thinned, stretched and dry mucous membrane of the prosthetic bed. To achieve success in the orthopedic treatment of such patients need to restore the volume and pliability of the mucous membrane of toothless prosthetic bed.

Carbon Transport

Shared mobility options, such as car sharing, are often claimed to be more sustainable, although evidence at an individual or city level may contradict these claims. This study aims to improve understanding of the effects of car sharing on transport-related emissions at an individual and city level. This is done by quantifying the greenhouse gas (GHG) emissions of the travel habits of individuals before and after engaging with car sharing. The analysis uses a well-to-wheel (WTW) approach, including both business-to-consumer (B2C) and peer-to-peer (P2P) car-sharing fleets. Changes in GHG emissions after engaging in car sharing vary among individuals. Transport-related GHG emissions caused by car-free individuals tend to increase after they engage in car sharing, while emissions caused by previous car owners tend to fall. At the city level, GHG emissions savings can be achieved by using more efficient cars in sharing systems and by implementing greener mobility policies. Changes in travel habits might help to reduce GHG emissions, providing individuals migrate to low-carbon transport modes. The findings can be used to support the development and implementation of transport policies that deter car ownership and support shared mobility solutions that are integrated in city transport systems.

AbstractShortly after the enactment of restrictions aimed at limiting the spread of COVID-19, various local government and public health authorities around the world reported an increased sighting of rats. Such reports have yet to be empirically validated. Here we combined data from multi-catch rodent stations (providing data on rodent captures), rodent bait stations (providing data on rodent activity) and residents’ complaints to explore the effects of a six week lockdown period on rodent populations within the City of Sydney, Australia. The sampling interval encompassed October 2019 to July 2020 with lockdown defined as the interval from April 1st to May 15th, 2020. Rodent captures and activity (visits to bait stations) were stable prior to lockdown. Captures showed a rapid increase and then decline during the lockdown, while rodent visits to bait stations declined throughout this period. There were no changes in the frequency of complaints during lockdown relative to before and after lockdown. There was a non-directional change in the geographical distribution of indices of rodent abundance suggesting that rodents redistributed in response to resource scarcity. We hypothesize that lockdown measures initially resulted in increased rodent captures due to sudden shortage of human-derived food resources. Rodent visits to bait stations might not show this pattern due to the nature of the binary data collected, namely the presence or absence of a visit. Relocation of bait stations driven by pest management goals may also have affected the detection of any directional spatial effect. We conclude that the onset of COVID-19 may have disrupted commensal rodent populations, with possible implications for the future management of these ubiquitous urban indicator species.

Background: Excessive use of smartphones may be associated with behavioral and physical health changes and might cause musculoskeletal alterations in the head and neck region. Objective: To evaluate the prevalence of smartphone addiction in college students and its correlation with symptoms of head and neck pain and masticatory and trapezius muscle activity while resting, before and after smartphone use. Methods: Twenty university students participated in the study. They answered the Smartphone Addiction Scale and the Fonseca Anamnestic Index. Next, the participants were seated and prepared for electromyography through the placement of surface electrodes on the masseter, temporal, and trapezius muscles. Rest condition data were collected for 10 seconds before and after 30 minutes of smartphone use. Results: The results showed that 35% of the evaluated individuals were classified as smartphone addicted and 35% reported no head or neck pain in the previous 30 days. There was no association between smartphone use and head and neck pain. In the electromyography, there was an increase in RMS values after smartphone use in the right and left masseter muscles and the left trapezius. Conclusion: College students presented a high prevalence of smartphone addiction and head and neck pain, but these were not statistically associated. There was a change in muscle activity only in the right trapezius muscles before and after 30 minutes of smartphone use. These findings are contrary to the current belief that the use of smartphones correlates with pain in the neck region and changes in the electrical muscle activity, leading to fatigue in the cervical muscles.
