Objectives: To study the influence of environmental pollution on the mineralization of dental hard tissues by using biosubstrates: teeth and hair. :Study design: At the first stage epidemiological survey was conducted in polluted and less polluted areas of Tbilisi (Georgia). We studied 525 children aged 3 and 4 years. Caries prevalence and intensity was defined by the methodology of World Health Organization. At the second stage the chemical elements content was studied in hair and teeth hard tissues of 24 children by X - ray fluorescent spectroscopy method. Results: The prevalence of dental caries in the polluted region was 46%, caries intensity − 1.92 (± 2.842). In the less polluted region prevalence was 37%, caries intensity − 1.47 (± 2.571). These data are statistically reliable (p < 0.05). The study of hair and tooth tissues showed that the toxic elements (Pb, Hg, Sn, Ti) content in these tissues was higher in environmentally unfavorable than in favorable conditions. Conclusion: Hair and dental tissues can be used as indicators of environmental pollution. Our survey showed that toxic elements content in dental hard tissues was higher and the level of essential elements was less in polluted than in less polluted areas of Tbilisi.

Pollution Exposure

Following environmental pollution exposure, calls to screen the population for disease or disease markers are often made. Population screening is a cross-sectional review of a population to find latent cases or biomarkers of disease that indicate the possibility of disease development; it differs from environmental screening or an epidemiological survey. Recognized standard approaches have been developed over 60 years to ensure quality and effectiveness in complex programs. We surveyed the literature for papers on health screening following environmental exposures and checked them for reference to accepted criteria such as those of Wilson and Jungner. We applied these criteria to three situations covering source/hazard (arsenic contaminated land), pathway/exposure (radiation release), and receptor/disease (lead poisoning). We identified 36 relevant papers. Although across the papers the whole range of criteria were addressed, no paper or program utilized recognized criteria. Issues and gaps identified included limited strategic approaches, lack of treatment, environmental prevention being seen as the screening outcome instead of treatment of identified individuals, and programs which did not fit the World Health Organization screening description. Robust discussion in the literature is needed to consider the organization and role of health screening following environmental exposures.

The  study aimed at identifying health leaders peculiarities forming carriages under the influence of factors of production for the purpose of scientific justification of low-cost and effective recovery measures are important because prolonged exposure to harmful factors on the health worsens and leads to various diseases, which adversely affects the workers to perform their duties.The aim of the study – to examine the state of dental hard tissues, to assess the intensity and peculiarities of clinical manifestations of both carious process and non-carious affects of dental hard tissues among the passenger car attendants of Chernivtsi station.Materials and Methods. To solve the tasks we examined 52 people, including 30 passenger car attendants of Chernivtsi station (treatment group) and 22 employees not exposed to harmful factors (experimental group). All patients were divided into four age groups and examined according to recommendations of World Health Organization on dental examination. Teeth assessment was conducted according to CFE (caries, filled, extracted) index.Results and Discussion. The degree of caries expansion among the passenger car attendants is 100 % in all age groups, the number affected teeth with caries depending on the length of service and age ranges from 20.0 to 25.97. Only half of teeth affected by caries is treated. Depending on the age from 12 % to 53 % of teeth are extracted.Conclusions. We recommend to restore the programs of dental diseases prevention that would include dental education of the employees, learning the rules of sensible nutrition, learning the rules of the mouth cavity hygienic care, secondary prevention (planned oral cavity sanation), dispensary observation.

Prevention of dental caries in children is one of the current problems of modern pediatric dentistry, which is due to the high prevalence and intensity of this disease. Analysis of the results of epidemiological studies conducted among children of different ages in the regions of Ukraine shows a significant increase in caries growth in recent years, both temporary and permanent teeth, which leads to in-depth study of the hardness of dental tissues to cariogenic factors in connection with the need in the constant improvement of methods of treatment and prevention of this pathology. The purpose of the study was to analyze the value of enamel caries resistance as a detector of resistance of dental hard tissues to carious process and its complications. The subject of the research is the work of domestic and foreign researchers on this topic. In the course of the research the bibliosemantic method and structural-logical analysis were used. Today, dental caries is the most common disease in different age groups, which is confirmed by the prevalence – 90-100% and a sharp trend of increasing its intensity. Given the high rates of this pathology, it should be remembered that its untimely treatment leads to the following complications: pulpitis, periodontitis, tooth extraction. An important concept that indicates the possibility of caries is caries resistance, which indicates the level of resistance of the enamel to caries and has an informative diagnostic value for the dentist. According to modern ideas, in the pathogenesis of dental caries the leading role is played by caries-resistant enamel. Its mineral base is formed by isomorphic crystals of apatite, which contain various chemical elements, and their amount in the body is closely related to the amount in the environment. It is established that more than 40 chemical elements take part in the process of tooth mineralization, the most important of which belongs to calcium, phosphorus, fluoride. Insufficient amount or excess of certain micronutrients in the environment, especially in soils and drinking water, can change their content in the body and, consequently, in the hard tissues of the teeth, affecting their resistance to caries. It is well known that the influence of a number of adverse environmental factors leads to a decrease in the resistance of the body as a whole and, as a consequence, to a decrease in the caries resistance of the enamel of the hard tissues of the teeth. Sensitivity to the effects of adverse factors increases significantly in the prepubertal period, a time not only of intensive growth of the child and the formation of his personality, but also a period of mineralization of more than half of permanent teeth. Therefore, exactly at this time dentists should pay special attention to the prevention of caries of permanent teeth in children by improving the conditions of secondary mineralization of tooth enamel, thereby increasing their level of caries resistance

Background: Environmental contamination with elevated levels of copper (Cu), cobalt (Co), iron (Fe), zinc (Zn), lead (Pb), chromium (Cr6+), cadmium (Cd), and nickel (Ni)—all states of which are found in Uganda—raises health risk to the public. Pb, Cr6+, Cd, and Ni for instance are generally considered nonessential to cellular functions, notwithstanding the importance of the oxidative state of the metals in bioavailability. As such, we aimed in this study (i) to evaluate heavy metal concentrations in four vegetables from a typical open-air market in Uganda, (ii) to assess the safety of consuming these vegetables against the World Health Organization (WHO) recommended limits of heavy metals consumption, and (iii) to formulate a model of estimated daily intake (EDI) among consumers in the country. Methods: This was a cross-sectional study conducted in five georeferenced markets of Bushenyi district in January 2020. Amaranthus, cabbages, scarlet eggplants, and tomatoes were collected from open markets, processed, and analyzed by atomic absorption spectrometry. Modeled EDI, principal component (PCA) and cluster analysis (CA) were conducted to identify relationships in the samples. Results: The levels of essential elements in the four vegetables were found to fall from Co > Cu > Fe > Zn. Those of non-essential metals were significantly higher and followed the pattern Cd > Cr > Pb > Ni. The highest EDI values were those of Cu in scarlet eggplants, Zn in amaranthus, Fe in amaranthus, Co in amaranthus, Pb in cabbages, total Cr in scarlet eggplant, Cd in cabbages and tomatoes, and Ni in cabbages. In comparison to international limits, EDIs for Zn, Cu, Co and Fe were low while Ni in cabbages were high. PCA showed high variations in scarlet eggplant and amaranthus. The study vegetables were found to be related with each other, not according to the location of the markets from where they were obtained, but according to their species by CA. Conclusion: The presence of non-essential elements above WHO limits raises policy challenges for the consumption and marketing of vegetables in the study area. Furthermore, low EDIs of essential elements in the vegetables create demand for nutritious foods to promote healthy communities.

Compound Odontoma

Odontomas represent the most common type of odontogenic benign jaws tumors among patients younger than 20 years of age. These tumors are composed of enamel, dentine, cementum, and pulp tissue. According to the World Health Organization classification, two distinct types of odontomas are acknowledged: complex and compound odontoma. In complex odontomas, all dental tissues are formed, but appeared without an organized structure. In compound odontomas, all dental tissues are arranged in numerous tooth-like structures known as denticles. Compound odontomas are often associated with impacted adjacent permanent teeth and their surgical removal represents the best therapeutic option. A case of a 20-year-old male patient with a compound odontoma-associated of impacted maxillary canine is presented. A minimally invasive surgical technique is adopted to remove the least amount of bone tissue as far as possible.

AbstractAccording to the World Health Organization estimates, approximately 10% of the world’s population is affected by depressive disorders. Furthermore, even in high-income countries, many people with depression are not treated, which can lead to serious health consequences and a global economic loss. Unfortunately, the current pharmacotherapy of depressive disorders is characterized by unsatisfactory efficacy and the therapeutic effect is accompanied by many side effects. For this reason, there is still ongoing worldwide research to find new antidepressant therapies. In recent years, many data have been shown that essential elements demonstrate the antidepressant action and increase the effect of antidepressants. In this paper we present the results from the preclinical and clinical studies published over the years which show the involvement of selenium and manganese in depressive disorders. In this article, the relationship between the amount of these microelements in a diet and depression is reviewed and what's more, the association among these elements in different biomaterial and their relations to depressive symptoms is presented. Additionally, we discuss the possible influence of selenium and manganese on modulating neurotransmitter system involved in depression.

Abstract In the course of the odontogenesis of bovine incisors several clearly distinguishable phosphohydrolase activities are observed in the pulp and in dental hard tissues. Using various substrates and inhibitors, unspecific alkaline phosphatase, two isoenzymes of acid phosphatase, Ca2+-activated ATPase and inorganic pyrophosphatase are characterized. The enzymatic activity of alkaline phosphatase in pulp and hard tissues is significantly high at the beginning of dentine and enamel mineralization. The specific activity of this enzyme decreases quite fast with the beginning of root formation, then more slowly, until it reaches a constant final value. Histochemical studies show that during mineralization the maximum of alkaline phosphatase activity is in the subodontoblasts. Lower enzyme concentrations are found in the stratum intermedium and in the outer enamel epithelium during that process. The specific activities of ATPase, acid phosphatases and pyrophosphatase show little temporal variation during tooth development, but they also appear in a characteristic spatial pattern in the dental tissues.

After the periodontium of the rat was wounded, the formation of acellular extrinsic fiber cementum (AEFC) did not appear to be restricted to the hard dental tissues (pre-existing cementum, dentin, and enamel). Layers resembling AEFC were also deposited along the inner wall of the alveolar bone. At the time of observation (six weeks after being wounded), cells other than fibroblast-like cells could not be distinguished close to the newly formed AEFC-like layers. We suggest that the deposition of this material was related to the activity of periodontal ligament fibroblasts.

ABSTRACT Background Oral health status of prisoners has been an area of concern worldwide. The prison population is unique in nature because of the complexities of their psychological, social and behavioral aspects. Limited oral healthcare facilities in prison settings have resulted in neglect of oral health among prisoners. Aim The present study aims to assess oral mucosal lesions among prisoners in Central Prison, Chennai. Materials and methods A cross-sectional epidemiological survey was conducted in Central Prison, Puzhal, Chennai. The study population consisted of 1060 prisoners from three divisions of the Central Prison. Oral mucosal lesions among the prisoners were assessed by a single investigator according to World Health Organization (WHO) specifications. Results The present study shows that among the study subjects, 37.7% of males and 17.1% of females developed oral mucosal lesions. The prevalence of smokers melanosis was 27.6% among males and 8.6% among females. The prevalence of oral mucosal lesions was found to be highest in study subjects of 55 years and above. Conclusion A large proportion of the study subjects had oral mucosal lesions. Oral mucosal lesions like oral submucosis fibrosis, smokers palate and smokers melanosis was found to be common among males than females. Oral healthcare facilities should be incorporated in prison settings which would intercept the progress of oral mucosal lesions. How to cite this article George B, Johny MK, Mathew TA.
