Introduction: Pandemics have affected and will continue to affect humankind. Historically the Human Immunodeficiency Virus changed the way dental clinics operate and the COVID-19 pandemic led to an unprecedented closure of dental clinics leading to short- and long-term impact on oral health.  Aim: To assess the impact on oral health and related behaviours related to modern pandemics.  Method: A literature search across eighteen electronic databases was conducted. Three reviewers screened 2029 articles against inclusion criteria and assessed quality. Included articles underwent thematic analysis, followed by narrative synthesis to describe the results.  Results: Forty-eight articles were included that identified themes: (i) oral health related quality of life, (ii) stress and pandemics, (iii) oral health behaviours, (iv) social capital, (v) access to oral healthcare, (vi) fear as a barrier to accessing oral healthcare and (vii) teledentistry.  Conclusion: Pandemics present multiple challenges to both individuals and oral health professionals that impact on oral health and these challenges disproportionately affect the most vulnerable communities. However, with the right support, these impacts can be mitigated through social capital and support to establish healthy routines. The use of digital technologies should be promoted to reach all communities before the next pandemic arrives.

Aim To determine relation between near work and myopia progression in student population. Causes of myopia occurrence are not sufficiently explained. Methods This retrospective-prospective, descriptive research included 100 students with verified myopia up to -3 Dsph. Ophthalmological examination and measurement diopter-hours variable (Dh) were done twice, in the period from January 2011 until January 2012. Results A multivariate regression analysis of impact on the difference of distance visual acuity without correction to the right and left eye and difference of automatic computer refractometry in cycloplegia of both eyes indicates that, diopter-hours variable (Dh) had statistically significant impact on increase of distance visual acuity difference (right eye OR: I measurement–Dh 1.489, II measurement–Dh 1.544, p<0.05; left eye OR: I measurement–Dh 1.602, II measurement–Dh 1.538, p<0.05) and automatic computer refractometry in cycloplegia (right eye OR: I measurement 1.361, II measurement 1.493, p<0.05; left eye OR: I measurement 0.931, II measurement 1.019, p<0.05) during both measurements. Conclusion Near work cause the increase of myopia. This research opened a perspective for other researches on the impact of near work on myopia.

Introduction: Sex determination is one of fi rst and most important steps in identifying disintegrated bodies and skeletal remains. During the exhumation of bodies from the mass graves and archaeologicalexcavations, it is quite often the case that not all bones of one person are found, therefore, teeth and the scull are the only true identifi cation material. Canines are teeth most appropriate for sex determination.The aim of the research was to determine sex identity of the Bosnian-Herzegovinian population based on odontometric characteristics of permanent lower canines.Methods: The research sample included 180 patients of the Dental Offi ce, of both sexes. All patients with permanent lower right and left canines, without caries, with healthy state of gingiva and periodontium,without crown restorations were included in the research. Measurement was done directly in the patients' mouth using a digital sliding caliper. Greatest mesiodistal width of the lower right and left canine and intercuspal distance of the lower jaw were measured.Results: All parameters were higher in case of male, including Mandibular Canine Index (MCI) (p<0.01). The precision of appraising the sex identity for the Bosnian-Herzegovinian population, based on MCI on the right, amounts 68.89% and 68.54% on the left.Conclusions: The study showed that right canines are signifi cantly broader than the left ones and they are broader in case of males. Lower right canines, that is, MCI on the right, indicates greater accuracy insex determination in relation to left lower canines. The accuracy in sex determination for all variables is higher for the female.

AIM To determine the relation between physical activity and myopia progression in student population. Causes of myopia occurrence are not sufficiently explained. METHODS This retrospective-prospective, descriptive research included 100 students with verified myopia up to -3 Dsph. The research was conducted in the Institute for Occupational and Sports Medicine of Zenica-Doboj Canton and at the University of Zenica in the period from January 2011 until January 2012. Ophthalmological examination and Multistage Fitness Test were done twice. RESULTS A significant correlation was recorded only according to assessment of physical competence during the second measurement with a negative sign, indicating that an increase of physical activity had an impact on the decrease of differences in values of automatic computer refractometry in cycloplegia of measurements (right eye Rho: -0.260, p less than 0.01; left eye Rho: - 0.255, p less than 0.05). Multivariate regression analysis of impact on the difference of distance visual acuity without correction as well as the impact on difference of automatic computer refractometry in cycloplegia indicated that assessment of physical competence during the measurements had statistically significant impact on the decrease of distance visual acuity between measurements (right eye OR: I measurement -0.748, II measurement -0.660, p less than 0.05; left eye OR: I measurement -0.613, II measurement -0.515, p less than 0.05) and on decreased difference of automatic computer refractometry in cycloplegia (right eye OR: I measurement -0.822, II measurement -0.831, p less than 0.05; left eye OR: I measurement -0.641, II measurement -0.706, p less than 0.05). CONCLUSION Physical activity did not cause the increase of myopia. This research opened a perspective for other researches on the impact of physical activity on myopia.

Summary Introduction: XXII European Congress of Medical Informatics (MIe 2009) took place in Sarajevo from August 30th to September 2nd 2009. Assessment of quality of papers presented at MIe 2009 was a process of observation, measurement, comparison and evaluation of the quality of orally presented papers. Methodology: For this study, and for the first time since EFMI founding (1976) and MIE congresses, the authors introduced a specially created quality assessment form with five relevant paper quality variables (methodological approach, international influence, scientific content, language quality, technical features) which the first author of this article used in peer-review process of papers submitted for publication in the journal Acta Informatica Medica (as Editor-in-Chief for last 18 years). The survey was conducted on the principle of random sampling of participants of MIE 2009 Conference in Sarajevo, where specially trained interviewers (final year students of medicine and engineering at the University of Sarajevo) interviewed 33 session’s chairs and 110 participants/listeners of MIE 2009 paper presentations in 33 sessions (of total 40). Data was collected, entered into a specially created database, analyzed and presented. Results: From the total of 150 oral presentations at the MIE 2009, 110 oral presentations were graded by both chairs and participants/ listeners. Grading results were compared and we found that in 60% of cases (66 papers) session chairs gave higher ratings than other participants of the congress. The highest rating was 10, and the lowest 3. Only 3 of the papers received all four grades 10 from the session chairs. The most common grade given by chairs of the session was 8 (26.36%), followed by 7 (20%), 9 (19.32%), 6 (13.18%), 10 and 5 (7.50%), 4 (5%) and 3 (1.14%). Significant differences in quality assessment of papers done by chairs and those done by other participants/listeners are observed. Conclusion: This work should demonstrate the importance of introducing universal (uniform) scale for assessment of articles at conferences that would provide objective and relevant assessment, which has not been the practice. Results obtained using a single standardized scale can be compared to each other and thus improve the quality of the articles and the congress. Future congresses can be organized in this manner and become leading events in certain fields of medical science.

CONFLICT OF INTEREST: NONE DECLARED Waste management is one of the key ecological challenges of the modern world. As dental practitioners, we must recognize that some of the materials and procedures we use to provide dental health services may present challenges to the environment. Realizing this, we can begin to take measures to minimize the production of these wastes and their potential environmental effects. Dental office waste typically cause toxic chemicals to enter our streams, sewers, and landfills. This paper identifies some common wastes produced by dental offices (dental amalgam, silver, lead, biomedical and general office waste) and provides practical suggestions for reducing the impact of our profession on the environment. To dispose of dental wastes, if recycling is not an option, proper disposal as hazardous waste is necessary. But, problem is that dental waste is in most cases dumped at uncontrolled disposal sites, and that is public health and ecological risk.

Health care systems today require some important changes. Many patients, doctors and other health professionals with right have suspicions that the health care system are managing available resources and information of interest in an optimal way, and as a result of that, health care that we receive isn’t of best possible quality. Considering the large investment in health systems, and the population with an increasing life expectancy, the mobility of patients and the emergence of new highrisk infectious diseases (HIV, SARS, etc.), modern systems of treatment must be proactive, efficient, economical and safe. To provide a basis for improving the quality of health care the system needs to meet several key preconditions and requirements. Professional groups from the world’s most advanced countries (USA, Japan, EU countries) have recognized the introduction of specialized computer and business solutions to national integrated information system in the field of health as a key component to improve the efficiency of the system, all in order to better manage the information of interest, and optimize the consumption and quality of resource management. Information systems must however meet very important common criteria that are based on openness, integration, security of data management, reliability and modularity. In this way it would ensure the vertical (within single health care institutions) and horizontal (between different separate institutions) interoperability of different solutions, and connectivity of different levels of health care within and outside the borders of individual states. Bearing in mind the requirements mentioned, this paper provides a short overview of Health Level 7 (HL7) as open information and communication technology (ICT) standard that should be adopted at the global level by professionals and users. Without quality standards that meet the needs of the business health systems, and ensure the applicability of existing and new solutions the above vision of integrated health care system is certainly not achievable.

Since the discovery of X-rays in 1895, film has been the primary medium for capturing, displaying, and storing radiographic images. It is a technology that dental practitioners are the most familiar and comfortable with in terms of technique and interpretation. Digital radiography is the latest advancement in dental imaging and is slowly being adopted by the dental profession. Digital imaging incorporates computer technology in the capture, display, enhancement, and storage of direct radiographic images. Digital radiography has been available in dentistry for more than 25 years, but it has not replaced conventional film-based radiography completely. This could be because of the costs involved in replacing conventional radiographic equipment with a digital imaging system, or because implementing new technology in the dental practice requires a bit of courage.

CONFLICT OF INTEREST: NONE DECLARED Evidence based medicine (EBM) is the conscientious, explicit, judicious and reasonable use of modern, best evidence in making decisions about the care of individual patients. EBM integrates clinical experience and patient values with the best available research information. It is a movement which aims to increase the use of high quality clinical research in clinical decision making. EBM requires new skills of the clinician, including efficient literature-searching, and the application of formal rules of evidence in evaluating the clinical literature. The practice of evidence-based medicine is a process of lifelong, self-directed, problem-based learning in which caring for one’s own patients creates the need for clinically important information about diagnosis, prognosis, therapy and other clinical and health care issues. It is not “cookbook” with recipes, but its good application brings cost-effective and better health care. The key difference between evidence-based medicine and traditional medicine is not that EBM considers the evidence while the latter does not. Both take evidence into account; however, EBM demands better evidence than has traditionally been used. One of the greatest achievements of evidence-based medicine has been the development of systematic reviews and meta-analyses, methods by which researchers identify multiple studies on a topic, separate the best ones and then critically analyze them to come up with a summary of the best available evidence. The EBM-oriented clinicians of tomorrow have three tasks: a) to use evidence summaries in clinical practice; b) to help develop and update selected systematic reviews or evidence-based guidelines in their area of expertise; and c) to enrol patients in studies of treatment, diagnosis and prognosis on which medical practice is based.
