Mechanism of the oxidation of nitric oxide with oxygen
Authors: Głowiński Józef , Józef Hoffmann , Wilk Marcin
Published: April 2021

Very fast reactions of forming higher nitrogen oxides set out an equilibrium framework for the course of the reaction of nitrogen monoxide oxidation. The slow course of reaction of nitrogen monoxide with oxygen permanently violates the created equilibria. In particular, the equilibrium of the oxidation reaction of nitrogen monoxide with nitrogen dioxide. The contribution of this reaction to the transformation of nitrogen monoxide in the conditions of nitrogen trioxide removal from the gas phase was estimated.

Type-2 diabetes (T2D) is a chronic condition, generally regarded as an irreversible, that is among the top 10 causes of death globally. The hallmark of T2D is hyperglycemia, which results from disturbances in insulin sensitivity, insulin secretion, β-cell dysfunction and insulin resistance. Several clinical and lifestyle factors are involved in the progression of T2D, such as obesity and physical inactivity. A high-calorie diet is the main contributor to the development of obesity, which results in T2D, as obesity or increased intra-abdominal adipose tissue is related to insulin resistance. Technological advances have contributed to individuals having a more sedentary lifestyle, leading to obesity and T2D. T2D can be treated with lifestyle interventions, such as diet and exercise. Herein, we highlight the positive impact of a very low-calorie diet (VLCD) and lifestyle modalities in the treatment and prevention of T2D. An inclusion of VLCD 400-800 kcal/day for 8 weeks and ≥ 150 minutes exercise 5 times a week as lifestyle interventions can decrease glucose levels to normal, reduce HbA1c and improve insulin resistance and sensitivity. Therefore, a potential mechanism in maintaining glucose homeostasis and remission of T2D by VLCD and exercise reduces body weight.
The Origins of Women’s Skirt and Shirt Clothing on the Moravian-Slovak Border and Its Central European Context
Authors: Šimša Martin
Published: April 2021

Over the past one hundred years, folk clothing has been considered one of the most significant elements of cultural heritage and has been perceived in this way not only by experts but, for many decades, by its wearers as well. In the present study, the author seeks to find an answer, based on an analysis of older expert texts, as to what formed the theoretical basis for this process, who were its representatives, at what conclusions they arrived, and how the methods of their work were reflected in the formulation of their conclusions. From the historical perspective, the study summarises the opinions on folk clothing, projected through the idea of Slavic unity, as can be observed in the case of Jan Koula and, through the reception of these opinions, also in the case of Lubor Niederle, Drahomíra Stránská and Viera Nosáľová. This work also offers newer reflections from the studies by Alena Jeřábková on the shaping of folk clothing within the Carpathian culture. Through the example of women’s linen skirts, the material part of the study seeks to point out the pitfalls of these approaches and highlight the need to study the construction of folk clothing from a longer historical perspective. Only in this way is the effect of clothing styles in the form of domestication of the individual pieces of stylish clothing evident, combined with older clothing layers. Even though most parts of folk clothing are not proto-Slavic and do not necessarily relate to the culture of the Carpathian curve, as a whole, they prove well the way the countryside managed to accept the transformations of contemporary fashion over the last four centuries and to incorporate them into a unique clothing complex.
Elements of Traditional Crafts as an Inspiration for Modern Design and an Incentive for Regional Development from the Perspective of Experts, Manufacturers and Users
Authors: Kotradyová Veronika , Borysko Wanda
Published: April 2021

The text seeks answers to the questions of what folk inspirations in design mean and whether local identity embedded in traditions can work as a brand able to interpret traditional products and samples and, subsequently, disseminate them by means of strategies used in design. It is a conscious, innovative process that draws creatively on local sources. Today, traditional forms and patterns are naturally present in real craft products as well as kitsch objects created as an expression of the commercialisation of tourism. Attention is also paid to the terms “craft product” and “regional product”, their significance and understanding by local manufacturers, users, self-governing bodies, and activities at the given location. The analysis of this topic is based on field research and the results of an internet questionnaire.
Analysis of Interventions to Reduce Antigypsyism in Slovakia: A Social Psychology Perspective
Authors: Hargašová Lucia , Lášticová Barbara , Poslon Xenia Daniela , Belán Dóra
Published: April 2021

Despite numerous efforts of Roma inclusion from various State and non-governmental organisations, segregation and socioeconomic marginalisation of the Roma is still widespread in Slovakia. In this paper, we show what social-psychological factors intervene into the process of intergroup relations change and how they can influence the effectiveness of interventions to reduce antigypsyism. We contend that establishing intergroup harmony between majority and minority may, by creating false assumptions about the absence of structural inequalities, weaken the potential for social change and minority collective action. Based on the theoretical analysis as well as the content analysis of anti-discrimination interventions carried out in the year 2018 and the thematic analysis of interviews with selected stakeholders (NGO representatives, intervention participants, sponsors) we identified four challenges that need to be tackled if the interventions are to succeed in reducing antigypsyism. These are: 1) essentializing vs. empowerment of minorities; 2) tension between the colourblind and multiculturalism approaches; 3) problem of intergroup boundaries and their consequences for generalization of positive intergroup attitudes to the whole outgroup; and 4) societal norms defining the nature of intergroup relations. We discuss how these challenges ought to be addressed in succesful anti-discrimination interventions.

Carbon Sequestration: an Answer to the World’s Carbon Dioxide Emission Problem
Authors: Wettstein Curtis
Published: April 2021

As of November 2007, 174 parties had ratified the Kyoto protocol signifying a large part of the solution to one of the worlds primary environmental problems; carbon dioxide emissions. Although the United States refused to sign the protocol, their neighbours in Canada were eager to address the issue and sign. However with oil being a major Canadian export, carbon dioxide emission reduction was arguably improbable and unprofitable. With the pressure of reducing carbon dioxide emissions an imminent, carbon sequestration may be the symbiotic solution in satisfying Kyoto, saving the environment and even increasing profitability. Carbon sequestration is the process where carbon dioxide is injected into an oil well in order to increase recovery. With tertiary oil recoveries driving much of the oil business, cheap and efficient recovery methods are invaluable. Presently there is a Canadian operation in Wayburn, Saskatchewan which employs the technique. In addition, Texas and Scandinavian oil companies are using Carbon dioxide injection. If carbon sequestration increases oil recovery it has to be the preferred method. By purchasing carbon dioxide from external sources and recycling their own, companies can reduce emissions while increasing profits. Finally it may be profitable to save the environment.
Investigation into Feasibility of Low-Enthalpy Geothermal Electricity Production in Hinton, Alberta
Authors: Foo Gordon , Douglas Matt , Wasik Trevor , Friley Sam
Published: April 2021

The aim of this study is to demonstrate the feasibility of electrical power generation from deep, low enthalpy geothermal resources surrounding Hinton, Alberta. Relict petroleum industry well infrastructure permits access to aquifers and water reservoirs up to 6000m deep, where heat from radioactive decay in the Earth's interior imparts sufficient thermal energy in formation water to mechanically drive a turbine at surface. The thermal energy isconverted to mechanical energy through a binary fluid cycle, where the heat in the formation water is transferred to a working fluid that vaporizes at a low temperature and engages a turbine. The heat-deficient formation water byproduct is recycled back into the aquifer, where it regains its thermal energy for subsequent exploitation. The closed-loop design of this system makes the resource renewable, sustainable and imparts a lower environmental impact than conventional methods of electricity generation. Rising energy prices and a growth in public interest for renewable energy resources have made geothermal electricity generation and heating an attractive target for further research and development in Canada. The study area, Hinton, Alberta is situated over an aerially limited geothermal heat anomaly in the Western Canada Sedimentary Basin. Public-domain geological data released by the petroleum industry, combined with currently developed geothermal mechanical technologies are used with to construct a hypothetical model for 1MW of electricity generation. Results are forthcoming.
Identities, Communities and Belonging: The Effects of Violence and Trauma on Jewish Women
Authors: Finestone Elana
Published: April 2021

This paper helps to explain why sensitivity to cultural context matters in terms of violence and trauma such as sexual assault, sexual abuse, rape, spousal abuse, assault, and / or surviving the Holocaust. My interest in this paper was stimulated through my volunteer work at a Family Service Centre for Jewish women in Ottawa called Shalom Bayit. This particular volunteer experience helped me to understand that cultural location determines how people express a violating and harmful experience and the type of support they receive. This paper will explore different cultural locations as well as agency to civil, criminal and religious law. Women’s agency plays a role in how Jewish women’s experiences are voiced and validated by their surrounding community. The following research has implications for professionals working with violated and traumatized women. This paper will be using a comparative method researching Jewish women with different identities. Examples of identities to be examined are Secular, Orthodox, Israeli, Lesbian, and Sephardi Jewish women.
Jazz Composition
Authors: Purchase Scott
Published: April 2021

Music composition is an art of courage and thoroughness. After nearly four years of playing jazz with Queen’s music professor Greg Runions (winner of the 2006-07 Queens Music Department Teaching Award) and studying music theory and analysis, I have recently delved into the fascinating art of writing original music in the broadly defined jazz idiom. The opportunity to give something back to the creative music community has been both humbling and inspiring. Through Prof. Runions impressive experience as a prolific local composer, I have learned about the challenges of connecting melodic ideas with music harmony that both pleases and challenges the listener. In two semesters of study, we have explored jazz arranging for a variety of instrument groups, the complex art of chord extensions and modulation, and writing melodies over chord progressions that are memorable and enjoyable. I have produced a dozen songs in lead sheet format, similar to the way music is found in jazz performance fake books. Some of these pieces have been fleshed out to cover a wide range of instrumental performance, including solo piano, jazz combo, vocal jazz ensemble, and full jazz ensemble. I plan to continue this process throughout my life as new inspiration and musical situations arise, seeking to grasp the expressivity and enjoyment that music instills in us all.

The unit of analysis of this research is companies listed on the Indonesia Stock Exchange which restate the company's 2017-2019. The data analysis technique used in this research is descriptive-qualitative. The results showed that of the 105 data companies that did the restatement, there were 52 data companies did the restatement due to the adoption of certain PSAK and / or ISAK, 26 data of the company did the restatement because there were changes in ownership including acquisition, purchase, sale of shares, and 27 company data conducts restatement due to the correction of recording / calculation / adjustment / recognition errors. This research has a limitation that is the very high adjustment of researchers because not all companies in the financial statements published on the IDX show the reasons for the companies to do restatement. Suggestions for further researchers are advised to use data restatement in the form of quantitative data so as to minimize the researchers' adjustment.
On the participation of natural salts in alkaline magmatism. Article 3. Genetic aspects of the model of salt-alkaline interactions
Authors: Belenitskaya G. A.
Published: April 2021

Research subject. An analysis of regional and global geological material characterizing the spatio-temporal relationships between alkaline magmatic and saline complexes allowed the author to propose and justify a new geological-genetic model of alkaline magmatism. This model considers saline complexes, located along the paths of the upward movement of deep magmas, as additional sources of alkaline and volatile components.

Materials and methods. Three articles are devoted to the discussion and justification of this model. Two articles were devoted to geological aspects of the problem. The prerequisites and signs of the participation of ancient saline complexes in alkaline magmatism were characterized. It was shown that the presence of saline rocks in the deep zones of the earth's crust along the paths of the upward movement of deep magma flows is a geologically natural and common phenomenon. Natural alkaline-salt associations (spatio-temporal combinations of alkaline and salt objects) were indicated; their tectonic types were distinguished. A global overview of their different-age analogues (neo- and paleogeodynamic) was given.

Results and discussion. The collected data made it possible to evaluate older (than magmas) salt-bearing complexes (deeply buried in the substrate) as a possible important and active participant in the ontogenesis of alkaline complexes, to give a positive assessment of the geological aspects of the “magma halocontamination” model and salt-magmatic interactions; to formulate the main geological-genetic provisions of this model.

Conclusion. This article focuses on the discussion of the genetic aspects of the proposed model with an assessment of the probable role and significance of various halophilic components in the formation of alkaline magmas and their features. For this purpose, the similarity features in the spatial and quantitative distribution of halophilic and foydaphilic components in salt and alkaline rocks are considered; the probable role of various halophilic components in the formation of alkaline specialization of magmas, in the emergence of a rich set of unusual features of alkaline rocks (material, structural, morphological, etc.) is discussed. The probability of participation of the complex of paragenic (non-salt) members of the halophilic community (dolomites, anhydrites, black shales and associated ore components) in the interaction with hot magma is estimated. A comparative analysis of some basic provisions of the model under consideration with other geological-genetic models of alkaline petrogenesis is performed. The advantages of this model and its predictive capabilities are evaluated. A number of ideas have been proposed by the author for the first time, thus requiring further elucidation.

Research subject. This article analyses specific features of secondary transformations of quartz grains under the influence of water-oil fluids on the example of the Tulsky and Bobrikovsky oil-saturated quartz sandstones of the Demkinskoye oil deposit in the south-east of Tatarstan.

Materials and methods. The research was carried out using the methods of optical microscopy, x-ray diffraction and electron paramagnetic resonance (EPR).

Results. On the example of the Tulsky and Bobrikovsky oil-saturated Visean quartz sandstones, we analysed the influence of wateroil fluids on rocks and features of the secondary transformations of quartz grains in the Demkinsky oil field in the southeast of Tatarstan Republic. In the oilcharge stage, the spatial redistribution of silica was realized. Quartz grains dissolved in the sole and middle part of the reservoir, precipitating in the form of chalcedony in the top part of the reservoir. The dissolution of quartz grains was promoted by micro defects concentrated on their periphery. The dissolution was triggered by both plastic deformations of minerals at the contacts and an increase in the alkalinity in the pore space up to pH = 9-10. Chalcedony aggregates were formed in the intergranular space of oil-saturated sandstones. Depending on the nucleation point of the siliceous substance and silica concentration in pore fluids, either single spherulitic or agate-type aggregates were formed. According to EPR, the studied chalcedony aggregates have a high content of paramagnetic E'-centres. This was caused by a deficiency of oxygen in the mineral-forming fluid during chalcedony precipitation.

Conclusions. Chalcedony precipitation underwent in acidic conditions, which led to silica-type metasomatism in the top part of the reservoir followed by substitution of muscovite grains by morphological fibrous chalcedony. Metasomatism affected the grains of both detrital muscovite and muscovite present as inclusions inside quartz grains. This process indicates the manifestation of surface and bulk diffusion of silica, affecting all clastic components.

The formidable challenge of maintenance of heavy duty equipment for the day-to-day manufacturing activities informed this research investigation. The study examined the impact of overall equipment effectiveness on return on investment in the Nigerian cement manufacturing industry. It focused on the key indicators of overall equipment effectiveness and their impact on return on investment. Ex-post facto research design was adopted in conducting the empirical investigation. The firms in the industry quoted in the Nigeria Stock Exchange (NSE) were studied. Longitudinal data of 15 years observation (2005-2019) were obtained and analyzed with ordinary least squares regression (system-OLS). The key indicators of overall equipment effectiveness subjected to empirical test proved positively significant to return on investment at the Coefficient values a1, a2 & a3 > 0; Prob.-values a1, a2, & a3 < 0.05 and t-Statistic values a1, a2, & a3 absolutely ≥ 2. These analysis results suggested that machine availability rate (MAR), machine production rate (MPR), product quality rate (PQR) variables of overall equipment effectiveness have significant linear effect on ROI. Based on these results, the study therefore recommends among others for top management’s support and commitment to proactive and continuous improvement production facilities maintenance for improved overall equipment effectiveness and sustainable corporate performance of firms in the industry.

Demographic changes such as the systematically growing number of older people and the decreasing number of births significantly influenced health policy and healthcare systems in various countries and also caused a significant demand for professional nursing care. The lack of medical staff – and in particular nursing – is a problem that many countries will have to face in the near future, including Poland. Staff shortages are one of the main factors determining the future health policy in the world. The forecasts of the Supreme Council of Nurses and Midwives regarding the situation of nurses in Poland show that in less than five years Poles can be deprived of professional nursing and midwifery care. According to the WHO, there are currently shortages of 7.2 million medical personnel in the world in relation to the reported needs, and according to the report of the Third General Human Resources Forum in Health Care, there will be a shortage of 12.9 million nurses in 2035. In this report, the WHO also warns that in the next 10 years nearly 40% of nurses will leave the profession. The reasons for shortage of nursing staff are multi-faceted and complex, requiring comprehensive solutions. Recommendations regarding nursing policy include the need to prepare and implement national social security programs in services provided by nurses, which would cover the issues of improving working conditions, employment and implementing mechanisms regulating remuneration.

Introduction. Pregnancy is a period of continuous change. Physiological, anatomical and biochemical changes, including fluctuations in the endocrine system, cause the occurrence of many disorders also within the skin and its appendages. They can occur at various stages of pregnancy and, depending on the subjective assessment, create a smaller or more complex problem. Aim. The aim of the study was to determine the most common cosmetic problems in pregnant women and to give them a subjective rank of severity, to show the means and ways women take to fight against these problems. Material and methods. 102 pregnant women took part in this survey study. It was conducted from November 2017 to March 2018 in gynecological clinics and pregnancy pathology wards in Krakow and Dabrowa Tarnowska. Results. The major and most common skin problem was stretch marks (98% of respondents). The problem of skin firmness loss concerned 34.31% of respondents, while 33.33% indicated the occurrence of pruritus, the appearance of acne and/or rashes was declared by 31.37% of respondents. Less frequently appearing changes were: dilated capillaries (20.58%), discoloration (16.66%) and excessive hair growth. The second trimester of pregnancy was considered the main moment of appearance of the changes. For most women, the skin care products used before pregnancy had to be changed. Over half of the respondents declared that they want to perform a professional cosmetic procedure. Most often, however, only after completing pregnancy. Conclusions. More emphasis should be placed on the correct interview with the client of a beauty salon and asking about a possible pregnancy. During pregnancy, the skin requires changes in the form of care, the vast majority of women will seek professional advice after childbirth.

Authors: Krasuska-Sławińska Ewa , Piekarska Paulina , Gietka Piotr , Wieteska-Klimczak Anna , Wadecka Mirela , Matosek-Rutkowska Anna
Published: April 2021

Chronic recurrent multifocal osteitis (CRMO) is a rare disease of an unknown aetiology, occurring mainly in children aged 4-14 years. It is characterised by recurring episodes of osteitis, with no detectable cause, lasting from several months up to a few years. It usually affects the metaphysis of long bones. Primary lesions in the form of isolated focuses rarely occur in the mandible. The clinical symptoms of CRMO include ostealgia, soft tissue swelling (oedema), skin reddening, and mild fever. The diagnosis is difficult. It involves numerous laboratory and radiological investigations. In order to exclude infectious and neoplastic aetiology, it is advisable to perform a tissue biopsy. The disease is long-lasting with exacerbations and remissions. The prognosis is uncertain. Non-steroidal anti-inflammatory drugs and empirical antibiotic therapy are a recommended first-line therapy; if no improvement is observed, corticosteroids should be used. The analysed case concerns a 10-year-old boy with mandible inflammation as the first symptom of chronic recurrent multifocal osteitis (CRMO). Mandibular lesions may be the first symptom of chronic recurrent multifocal osteitis. The non-specific onset and variable clinical picture delay the diagnosis. Early diagnosis enables early treatment, which prevents complications.
Application of the MTA in the management of pulpal floor perforation – a case report
Authors: Porenczuk Alicja
Published: April 2021

Pulpal floor perforation, defined as the communication between the canal system and the root’s external surface, is one of the complications in endodontic treatment. Lack of sufficient closure of the perforation may result in the failure of the treatment. A material dedicated for the closure of the perforation is the MTA (Mineral Trioxide Aggregate) cement. The study presented herein shows a case of an old pulpal floor perforation in the lower left second molar (tooth 37), co-existing with the damage to the periodontal tissues, omitted mesiolingual canal and the inflammation in the periapical area. An initial cone beam computed tomography analysis helped to plan the retreatment and determine the prognosis. Written consent from the Patient was obtained. The endodontic retreatment, including the disinfection and closure of the perforation with the MTA, was successful. The control radiographs and clinical assessments after 4 months and 3 years showed complete regeneration of inflammatory lesions and new bone structure in the furcal area. The MTA cement is effective in closing old pulpal floor perforations and allows for the regeneration of the lost bone in the furcal area.

Introduction. Pregnancy is a special period in the life of a woman, when she cares not only for her own health, but also for that of her unborn child. Prenatal care is defined as comprehensive and multidisciplinary care provided to a pregnant woman, developing foetus, and then a newborn. The aim of caries prevention in pregnancy is not only to protect the future mother from caries, but also to prevent the disease in the child. Aim. The aim of the paper was to present the recommendations on preventive and therapeutic dental management in pregnant women with regard to oral diseases in the mother and her child. Material and methods. Electronic search for literature in medical databases (Pubmed, EMBASE, MEDLINE) and manual search for literature on primary-primary prevention of dental caries and dental care in pregnancy. Results. The available literature indicates the safety of preventive and therapeutic activities during pregnancy, including the use of local anaesthesia and dental diagnostic radiology. Although dental treatment requires some modifications due to pregnancy-related changes, it may be safely used for the benefit of the mother’s and the child’s health. Conclusions. Dental care in pregnancy should be primarily dedicated to education, prevention and treatment, if needed. Future mothers should be made aware that the child’s oral health can and should be taken care of already in the prenatal period.
Metalloproteinases and their role in the degradation of bonding systems. Part 2

The stability of the hybrid layer is crucial for ensuring the durability of fillings made of composite materials. Factors which weaken the bond strength are related to, among others, the presence of bacteria and their enzymes in the structure of the bacterial biofilm. Chronic damage the hybrid layer is also a result of hydrolysis and leaching of adhesive monomers which infiltrated the demineralised dentin matrix. Nanoleakage is also among the factors contributing to degradation. Many studies examine the effect of endogenous proteases on the degradation of the hybrid layer. Endogenous collagenolytic enzymes: metalloproteinases (MMPs) and cysteine cathepsins, are responsible for the degradation of the collagen matrix in the hybrid layer. Inhibition of endogenous proteases is therefore necessary to slow the degradation of fillings. The enzyme activity in dentine and in the hybrid layer can be regulated by endo- and exogenous inhibitors. The paper is a review of the available literature published in the PubMed medical database, as well as in Polish dental journals in the years 2002-2017. Its aim is to assess the role of metalloproteinases and cysteine cathepsins in the degradation of the hybrid layer and to review the compounds with inhibitory properties in relation to these enzyme groups.
Application of Kazanjian’s vestibuloplasty in the prevention of gingival recession in children – a report of two cases
Authors: Sobiech Piotr , Szerszeń Marcin , Wiśniewska Julia
Published: April 2021

The period of teeth replacement and the development of stomatognathic system are characterised by intense changes in the periodontium. The position of frenulum and the width of the attached gingiva begin to stabilise, but early abnormalities may contribute to disorders in normal structure and aesthetics. Mandibular incisor gingival recessions occurring in children during this period are not uncommon. Despite the possibility of spontaneous reversal with the development of the stomatognathic system, some patients require surgical treatment. Rapid intervention is necessary to prevent periodontal abnormalities from becoming permanent and to avoid greater destruction. We describe 2 cases of young patients undergoing vestibuloplasty by the Kazanjian technique. The choice of this approach was based on the surgical protocol, which could be used in a relatively cooperative patient. Surgical procedures in children must be rapid and generate predictable and safe treatment outcomes. It is also important that convalescence after the procedure does not limit patient’s functioning and requires no extreme care from the patient. The effects are fully satisfactory in terms of both aesthetics and health.
A child’s first dental visit – age and reasons. A literature review

Dental caries is a multifactorial disease, which may begin shortly after tooth eruption. The development of a carious lesion is conditioned by the lack of or irregular dental visits, incorrect oral hygiene, and poor dietary habits. Dental caries is still a very serious health problem in the paediatric population in Poland. It is extremely important that the child’s first adaptation visit to the dentist takes place at an early stage of the child’s life. The purpose of this early visit is not only to assess child’s dentition, but first and foremost to provide parents with guidance on proper child’s oral hygiene and to correct improper dietary and eating habits. The aim of this study was to determine the age at and the reasons for the child’s first dental visit based on the current literature. A review of the literature published in the years 1992-2017 was conducted using the PubMed and Google Scholar databases. The study was supplemented with papers published by Polish authors discussing the issues in question. A total of 39 literature positions regarding this field were selected and analysed. The obtained data indicate that the first dental visit of a child takes place much later than recommended in medical guidelines. In most cases, it is a symptomatic visit resulting from the presence of advanced carious processes.
Orthodontically induced root resorption – a literature review
Authors: Pogorzelska Anna , Stróżyńska-Sitkiewicz Anna , Szopiński Kazimierz
Published: April 2021

Root resorption in moved teeth is a common undesirable side effect of orthodontic treatment. This pathology usually affects permanent teeth. Although any part of the root may be involved, the apical or cervical area is usually affected. The formation and development of these changes are a long-term process and depend on various factors. The etiology of resorptive changes associated with orthodontic treatment has been widely discussed by many authors, who proposed numerous classifications. Particularly noteworthy are the works on techniques for the treatment of malocclusion and their potential adverse effects. Modern diagnostic methods allow for an early detection of this pathology and the implementation of appropriate therapeutic measures. These techniques include periapical radiography (paralleling technique) combined with cone-beam computed tomography. Dentists not only notice the need to achieve a beautiful smile, but they also take into account possible root shortening. This process is not fully understood, but realizing its existence is important for planning and implementing both orthodontic and general dental treatment.
Deep penetration fluoridation for caries prevention and treatment: the use of Tiefenfluorid® junior in children. Case reports
Authors: Kozaczuk Swietłana
Published: April 2021

The use of fluoride, a healthy diet and good dental care habits are the pillars of the fight against caries. At a time when the anti-fluoride movement is on the increase and raises doubts even amongst the dentists and dental hygienists, the dental environment should be based on the credible scientific evidence regarding the effectiveness and safety of therapy in their clinical management. The article presents the clinical cases in which the agent for deep penetration fluoridation Tiefenfluorid® junior (Humanchemie, German) was used in the treatment and prevention of carious lesions in children. The visual-tactile method was used for detecting caries lesions. The International Caries Detection and Assessment System – ICDAS II was used for classifying dental caries. Carious lesions activity were assessed using visual-tactile method at control visits every 3 months within 12 months. Fluoride is effective in the treatment of initial caries in enamel, and the agent based on silver and fluorine SDF (Silver Diamine Fluoride) effectively inhibits tooth decay in the dentin. The disadvantage of SDF is the black color of the teeth. In contrast to common fluoride compounds, the solution with fluoride Tiefenfluorid® junior (Humanchemie, German) becomes non-toxic due to the reaction with the second application solution with calcium hydroxide. Furthermore, the process takes place deep in the funnels of the dental enamel, not on the tooth surface. The deep penetration fluoridation can be used for the caries prophylaxis, including the mineral fissure sealing, as well as for the treatment of initial caries lesions. In the treatment of initial caries in small children, it is an alternative to the silver nitrate impregnation and for the fluoride varnishes.
