Exploring academic teachers perspectives regarding the impact of using medical simulation in dentistry pre- and post-COVID-19 pandemic: a qualitative study.

BACKGROUND: Medical simulation allows for the achievement of many educational goals and the continued education of some practical skills. The COVID-19 pandemic's restrictions have led to a major increase in dental education simulations. The aim of this study was to analyse the perspectives of academic teachers towards dental simulation, their concerns and evaluation of this teaching method, as well as their opinion on the use of medical simulation during the COVID-19 pandemic. METHOD: A focus study was conducted in a group of 5 academic teachers, comprising 10% of academic teachers of a Dental Faculty using simulation techniques. Prior to and during the COVID-19 pandemic, the interviewed teachers had expertise with medical simulation in dentistry education methods. A facilitator used pre-planned, open-ended questions about the use of simulation in dentistry also with regard to the COVID-19 pandemic period. The group discussion has been managed, monitored, and recorded. The data analysis model was based on Braun and Clarke's six phases of thematic analysis. Five thematic domains/fields were evaluated: (1) Simulation as a didactic method; (2) Simulation during COVID-19 pandemic; (3) General observations and expectations with regard to simulation; (4) Teachers in simulation; (5) Concerns in relation to simulation. Two researchers analysed the data. RESULTS: Based on interviewed teachers' perspective the simulation allows students to learn basic and complex skills providing the repeatability of the procedures performed. During Covid-19 the simulation methods undoubtedly filled the gap in the training of future dentists. However, interviewed teachers pointed out the high cost of the methods dictated by the need to prepare the simulation environment at a high level, in order to reflect the real clinical situation. CONCLUSIONS: The use of simulation methods requires adequate preparation of academic teachers, continuous education and updating of knowledge in the field of medical simulation. The COVID-19 pandemic significantly influenced the growth of dental education simulation techniques as well as staff knowledge of the usage of medical simulation.

Root Canal Infection and Its Impact on the Oral Cavity Microenvironment in the Context of Immune System Disorders in Selected Diseases: A Narrative Review.

The oral cavity has a specific microenvironment, and structures such as teeth are constantly exposed to chemical and biological factors. Although the structure of the teeth is permanent, due to exposure of the pulp and root canal system, trauma can have severe consequences and cause the development of local inflammation caused by external and opportunistic pathogens. Long-term inflammation can affect not only the local pulp and periodontal tissues but also the functioning of the immune system, which can trigger a systemic reaction. This literature review presents the current knowledge on root canal infections and their impact on the oral microenvironment in the context of immune system disorders in selected diseases. The result of the analysis of the literature is the statement that periodontal-disease-caused inflammation in the oral cavity may affect the development and progression of autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, or Sjogren's syndrome, as well as affecting the faster progression of conditions in which inflammation occurs such as, among others, chronic kidney disease or inflammatory bowel disease.

Physicochemical Properties and Surface Characteristics of Ground Human Teeth.

Enamel, dentin and cementum apatite has a complex composition. The lack of complete reports on the chemical composition of all tooth tissues together and the need to create a modern biomaterial that reproduces the correct ratio of individual tooth mineral components prompted the authors to undertake the research. A detailed evaluation of the micro- and macro-elements of tooth powder, using various methods of chemical analysis was conducted. All four groups of human sound teeth were crushed using the grinder. A fine powder was implemented for the FTIR (Fourier Transform Infrared Spectroscopy), ICP (Inductively Coupled Plasma Optical Emission Spectometry) and for the potentiometric titration, SEM and mercury porosimetry analyses. The obtained studies indicate that there is no significant correlation in chemical composition between the different teeth types. This proves that every removed, crushed tooth free of microorganisms can be a suitable material for alveolar augmentation. It is essential to know the chemical profiles of different elements in teeth to develop a new class of biomaterials for clinical applications.

Importance of most frequent needs of the disabled in shaping areas of support in public health. Part 1. Analysis of selected demographic and social characteristics of the disabled with consideration of the causes of body dysfunction, legal disability status, and selected characteristics of the state of health.

INTRODUCTION AND OBJECTIVE: The disabled are a group with a heterogeneous structure of causes and needs. The occurring physical, health, and social barriers constitute areas of public health. Assessment of these barriers requires systematic studies in order to use results supporting the tasks of public health, indispensable for pursuing the challenges of sustainable development. The aim of the study was to discuss the selected demographic, social, living and housing, as well as economic characteristics of the disabled rural and urban inhabitants, which are important for shaping the tasks of public health. MATERIAL AND METHODS: The study group consisted of 676 disabled aged 19 - 98 years, including 56.4% of females and 43.6% of males, 38.0% of whom lived in rural areas. The disabled were qualified into a study group by the method of targeted sampling. The research instruments were an author-constructed Disability Questionnaire, and the Research Protocol. Statistical analysis was performed using the software IBM SPSS Statistics v. 27. The p values p < 0.05 were considered statistically significant. RESULTS: The level of risk of the phenomenon of disability was similar among both males and females. Higher risk was observed among widows and widowers, females with a low level of education, the disabled in older age groups, as well as those living in rural areas, maintaining themselves on non-earned sources of income, and running a single person household. The main causes of disability were diseases. CONCLUSIONS: 1. The majority of the population in the study were disabled with a legal grade of disability. 2. The analyzed characteristics fell within two groups: demographic and social, and health characteristics with difficult to separate health and social problems. 3. The most important problems in the area of public health were specified. 4. It is necessary to conduct studies considering demographic and social variables in order to level-up health inequalities between the disabled and those able-bodied. Effective solving of barriers and risks embedded in the social, family, and occupational situation prevents secondary disability, and also provides an opportunity for sustainable development in this population group.

Contemporary Approach to the Porosity of Dental Materials and Methods of Its Measurement.

Porosity is an important parameter for characterizing the microstructure of solids that corresponds to the volume of the void space, which may contain fluid or air, over the total volume of the material. Many materials of natural and technically manufactured origin have a large number of voids in their internal structure, relatively small in size, compared to the characteristic dimensions of the body itself. Thus, porosity is an important feature of industrial materials, but also of biological ones. The porous structure affects a number of material properties, such as sorption capacity, as well as mechanical, thermal, and electrical properties. Porosity of materials is an important factor in research on biomaterials. The most popular materials used to rebuild damaged tooth tissues are composites and ceramics, whilst titanium alloys are used in the production of implants that replace the tooth root. Research indicates that the most comprehensive approach to examining such materials should involve an analysis using several complementary methods covering the widest possible range of pore sizes. In addition to the constantly observed increase in the resolution capabilities of devices, the development of computational models and algorithms improving the quality of the measurement signal remains a big challenge.

Anti-vaccine movements - a form of social activity for health care, ignorance or diversion aimed at destabilizing the health situation? Part 1. Epidemiological safety. Vaccinations - pros and cons.

INTRODUCTION: Vaccinations are a way accepted by science of preventing infectious diseases. Because of their epidemiological significance, vaccinations are considered compulsory in many countries and their evasion is penalized. Anti-vaccine movements may pose a threat to the epidemiological situation in many countries. The study presents the arguments formulated by opponents of vaccination and provides counter-arguments. MATERIAL AND METHODS: The study is based on the analysis of data stored in scientific databases, information obtained from Google, Bing and Yahoo on the Internet, as well as newspapers, magazines and opinion-forming websites. RESULTS: The slogans propagated by anti-vaccination movements are usually based on easily proven erroneous theories and lies, although there are also arguments expressing belief in the conspiracy of governments, politicians and vaccine manufacturers, or incompetence of scientists and practitioners. CONCLUSIONS: In recent years in Poland, the activity of movements against vaccination has increased significantly, and their propaganda, through its negative impact on social attitudes, threatens to destabilize the epidemiological situation. Analysis of arguments used by the opponents of vaccination suggests a lack of reliable knowledge, religious overtones (addressed to people with fundamentalist personalities), or the ill-will attitudes of anti-vaccine individuals/groups used for their own purposes. Familiarization with the arguments of anti-vaccine propaganda is necessary in order to implement effective methods of fighting such attitudes and beliefs.

Anti-vaccine movements - health care, ignorance or a diversion aimed at destabilizing the health situation? Part 2. Contemporary conditions for the functioning and development of anti-vaccination movements.

INTRODUCTION: Vaccinations are a way accepted by science of the struggle against infectious diseases. Because of their epidemiological significance, vaccinations are considered compulsory in many countries and their evasion is penalized. The WHO experts list anti-vaccine attitudes and movements among the top 10 threats to human health. Most people's refusals are mainly due to fears of anti-vaccine propaganda. Understanding this phenomenon will be the basis for improving the epidemiological situation in Poland. MATERIAL AND METHODS: The study is based on the analysis of data stored in scientific databases, as well as information obtained from Google, Bing and Yahoo and newspapers, magazines and opinion-forming websites. RESULTS: The anti-vaccine movements occur due different motivations, such as ignorance, fear and religious beliefs. Sometimes they can be supported by foreign services aimed at destabilization in selected areas of the globe. CONCLUSIONS: Increased activity and effective propaganda carried out by anti-vaccination movements is possible, among others, thanks to the development of the so-called 2nd generation of the Internet (Web2), enabling the free and difficult to control flow of information. Increasing data indicate that the activity of anti-vaccine movements may be a form of organized action (diversion in cyberspace) aimed at social, epidemiological, and economic destabilization of selected countries and regions. Among the various forms of combating anti-vaccination movements currently used are awareness-raising activities and restrictions on freedom on the Internet by monitoring information flow, blocking materials containing selected phrases or keywords associated with anti-vaccine propaganda, and sanctions imposed on people avoiding vaccination.

Acceptance of illness by women with breast cancer.

INTRODUCTION: Despite great progress in the diagnostics and treatment, breast cancer still remains the most frequently diagnosed malignant cancer in women. The outcomes of cancer treatment depend, to a considerable extent, on the degree of acceptance of the illness. The objective of the study was determination of the level of acceptance of the disease among the examined women with breast cancer. MATERIAL AND METHODS: The study covered a group of 231 women who received treatment for breast cancer in the Rev. Bronislaw Markiewicz Subcarpathian Oncology Centre in Brzozow, south-eastern Poland, and conducted by the method of a diagnostic survey, using an author constructed questionnaire and the standard Acceptance of Illness Scale, adapted by Z. Juczynski. Statistical analyses were performed using the software IBM SPSS v. 21.0.0.1. The p values p≤0.05 were considered statistically significant. RESULTS: The mean level of acceptance of the illness in the examined group of women was 26.53 (SD = 7.71; Me = 26). The largest number of respondents (50.6%) obtained scores within the range of 20-29, according to the AIS Scale. From among the adopted variables, the level of acceptance of the illness significantly varied according to age and occupational activity. However, no such differences were confirmed according to the place of residence, marital status, education level, or the type of occupation performed. CONCLUSIONS: In the examined group of women, a mediocre level of acceptance of cancer was observed. The respondents' age and occupational situation exerted a significant effect on the level of acceptance of the illness. The results of the study should be considered as satisfactory because the number of women with a high level of acceptance of breast cancer was more than twice as high as those ones with a low acceptance of the disease.

Meeting needs for rehabilitation equipment and home adjustments among the disabled in their life environment.

INTRODUCTION: The elimination of functional barriers resulting from disability through the provision of adequate orthopaedic and rehabilitation equipment, and homes adjusted for disability is the precondition for an efficient and independent functioning, and high quality of life of the disabled. The objective of the study was recognition of the needs of the disabled declared by them, and the degree of satisfaction with these needs. METHODS: The study covered 478 disabled from the Lublin Region. The research instrument was the 'Questionnaire for the Disabled' designed by the authors. RESULTS: Considering the needs expressed by the respondents concerning the provision of orthopaedic and rehabilitation equipment and meeting these needs, four groups were distinguished: No Needs - 30.1%, Needs Partially Met - 22.4%, Needs Fully Met - 37.7%, Needs Not Met - 9.8%. The group Needs Not Met was characterized by younger age, in the group Needs Partially Met worse indicators of the state of health were noted, more frequent independent living, loneliness and low material standard. Considering the expressed needs for home adjustments adequate to disability and meeting these needs, three groups were distinguished: No Needs - 59.6%, Needs Not Met - 15.9%, and Needs Met - 24.7%. The group Needs Not Met more rarely covered respondents living in residential homes, compared to those living independently in rural or urban areas. The group Needs Met more rarely included rural inhabitants, while more frequently including the disabled who had a high material standard. CONCLUSIONS: Both the provision of orthopaedic equipment and adjustment of the home to disability are insufficient with respect to the needs. The meeting of these needs is significantly conditioned by high or very high material standard. The lack or incomplete satisfaction with the needs for rehabilitation equipment is associated with a relatively younger age, independent, single residence and low material standard. Living in an residential home means better adjustment of the living environment, and better provision with orthopaedic and rehabilitation equipment.
