Academic mobility is a valuable and indispensable mechanism in each country's higher education quality assurance system. It also contributes to building and improving the capacities of individual universities because it enables the introduction of positive and proven teaching practices, modern teaching and research methods, and operational and administrative processes. The added value of mobility is the establishment of personal contacts and professional networking of teaching, scientific, artistic and non-teaching staff of the University of Sarajevo (from now on: "UNSA"), which has a long-term effect on the development of teaching, scientific and technological capacity. Studying through mobility gets an international note - students understand their work in a global context, their CV is enriched with new experiences, their knowledge of a foreign language (s) is improved, and after graduation, they become a competitive workforce. Teaching / scientific, artistic and non-teaching staff gain international experience through mobility, improve themselves, participate in active professional development, and increase the quality of the working environment. In the last 15 years, the University of Sarajevo has had over 2,500 outgoing mobility while hosting more than 1,500 international students, teaching / scientific, artistic and non-teaching staff. The mobility of students and staff significantly improves both the quality and the professional standard of UNSA activities. It indirectly contributes to the development and transformation of society as a whole. Through the integration of UNSA, many processes are uniform and simplified, but still, the heterogeneity and specificity of each organizational unit are present. In addition to all the benefits of student mobility, the most significant administrative challenge is the equivalence and recognition of ECTS credits earned at foreign institutions upon return to home institutions. Student services are faced with many formalities around keeping registers and other administrative forms that need to be tailored to exchange students. The current legal regulations in higher education do not value participation in mobility programs, which is undoubtedly not motivating for students and staff to get involved in them. On the contrary, the current vague legal framework and administrative barriers are significantly demotivating for students as they lose a semester or school year due to participation in mobility programs. It is necessary to develop more adequate regulations that will encourage more frequent, productive, more straightforward and better implementation of academic mobility for students. This could be achieved through participation in programs intended for international students (one-year specialist study, master's degree, dual education, summer schools, etc.). It is necessary to develop mechanisms for adequate evaluation of mobility for teaching, artistic and scientific staff of UNSA, which is particularly important for advancement to higher academic titles. It is also crucial to promote the exchange of administrative staff, which is often unjustifiably neglected, to improve the administrative processes at UNSA and its (sub) organizational units. To achieve this, we should be focused on developing cooperation with potential partners interested in administrative / non-teaching staff mobility.

This paper aims to propose a statistical model to assess pubertal growth spurt using the ratio of the anterior height projection to the posterior (Vba) of the fourth cervical vertebra body (C4) on cephalograms and to calculate the residual proportion of skeletal maturation and the time for the pubertal growth spurt to end for a given Vba. A sample of 538 cephalograms from healthy-living children aged between 5 and 15 years was analyzed. A segmented regression model was used to explain the different Vba stages relative to the pubertal growth spurt. In addition, the time to achieve skeletal maturation was evaluated for a given Vba between the beginning (Vba1) and the end (Vba2) of the pubertal growth spurt. A longitudinal sample of 25 males and 25 females was analyzed to validate the proposed method. The values of Vba corresponding to higher pubertal development rate ranged from Vba1 = 0.677 (95%CI, 0.644–0.711) to Vba2 = 0.966 (95%CI, 0.905–1.028) and from Vba1 = 0.669 (95%CI, 0.645–0.693) to Vba2 = 1.073 (95%CI, 1.044–1.101) in males and females, respectively. The validation process results showed that our model did not produce any incorrect forecasts. The proposed method estimates the beginning and the end of the pubertal growth spurt together with the residual proportion of skeletal maturation for a given Vba.

Introduction: In dental clinical practice, devices such as mobile phones and DSLR cameras (Digital Single Lens Reflex) are used to take intraoral and extraoral photographs. The existence of a large number of studies would allow the establishment of standards for the analysis of photographs and their wider use in daily practice in order to establish a rapid diagnosis, predictability of results and the development of teledentology during the COVID-19 pandemic. The aim of the pilot study was to determine the repeatability of point positioning in the analysis of facial symmetry in digital 2D photography. Materials and methods: One face was photographed using two different photography techniques. Points were positioned in one photo and used for each subsequent measurement. Two evaluators positioned 20 points in three time-separated periods. Results: The results suggest a relatively high degree of agreement of the point positioning provided by the two evaluators. Absolute matching of estimates was registered on 22 parameters (ICCs = 1.00), while on another 17 this value was high (ICCs >.96) Conclusion: This study shows that the values of the interclass of correlation coefficients calculated by the method of two-way random effects for each of the six indices are higher than the values of the lower limit of acceptability (ICC> 0.70). It is necessary to do additional research that will include a larger sample and different phone models to establish the diagnosis of facial asymmetry and the development of teledentistry.

Introduction/Objective. Deprogramming of the neuromuscular system with the use of stabilization splint might provide more precise evaluation of the centric relation (CR) - maximum intercuspation (MI) discrepancy. The study aimed to evaluate the differences between the bite registrations obtained in the CR before and after the application of the stabilization splint therapy. Methods. The sample included 48 non-deprogrammed individuals without any apparent signs and symptoms of temporomandibular disorders (TMDs). The neuromuscular system was deprogrammed by employing stabilization splint therapy. A condylar displacement evaluation was performed on vertical, horizontal and transverse planes of space, with the assistance of a condylar position indicator (CPI). Results. The mean values of condylar displacements, which were obtained after the deprogramming of the neuromuscular system, were significantly greater than those obtained before neuromuscular deprogramming for vertical condylar displacement (p < .0001). A greater degree of condylar distraction was observed on the left side of the vertical plane before (p < .01) and after neuromuscular deprogramming (p < .05). The highest level of condylar displacement occurred in the postero-inferior direction subsequent to the muscle deprogramming. Conclusion. It was observed that the level of average condylar displacements was significantly higher following the deprogramming of the neuromuscular system compared to that recorded before neuromuscular deprogramming using stabilization splint therapy. A more precise orthodontic diagnosis could have been obtained if the condyles were placed in a more exact CR position by muscle deprogramming.

Background: Periodontal complications are one of the common side effects associated with orthodontic therapy. Objective: This study aimed to evaluate the periodontal changes in patients before, during, and after the therapy with a fixed orthodontic appliance. Methods: Out of 38 healthy adolescents with permanent dentition who were indicated for fixed orthodontic therapy were included in this study. Patients were selected from Class I, treated by non-extraction methods, by using conventional orthodontic braces. After their examination and treatment by an orthodontist, the patients were referred to the periodontist before the placement of a fixed orthodontic appliance. The patients underwent the application of a periodontal anamnestic-diagnostic protocol, and the clinical-radiological evaluation. After a fixed orthodontic appliance was placed, the respondents were referred to the periodontist for regular mandatory check-ups, initially, after three months, and later on-after 6 months, after 1 year and after 2 years until the end of orthodontic therapy. Results: An increase in the mean value of the Plaque Index and Sulcus Bleeding Index was found at each check-up after the placement of a fixed orthodontic appliance. There is a statistically significant difference in the presence of gingival hyperplasia found by monitoring the changes after three and six months, and after one and two years following the start of orthodontic therapy. Conclusion: The assessment of periodontal changes in patients before, during and after the completion of fixed orthodontic therapy revealed that there is a strong need for mutual and close cooperation between orthodontist and periodontist during orthodontic therapy.

Introduction: Obstructive sleep apnea (OSA) is characterized by the cessation of air flow during sleep due to an obstruction in the nasopharyngeal/oropharyngeal region. The consequences that untreated obstructive sleep apnoea might have on patient’s health include symptoms like sudden awakening with a sensation of suffocation, morning headache, daytime sleepiness and fatigue, lack of concentration, and it is commonly connected to hypertension, coronary artery disease, depression, obesity and other medical conditions. Aim: The purpose of this review study is to enlighten the role of an orthodontic professional in prevention and treatment of obstructive sleep apnea syndrome to the general public. Methods: Data search was determined by the following keywords: sleep apnea, orthodontic abnormalities, orthodontic prevention, sleep apnea syndrome, obstructive sleep apnea, cephalometric analysis, AHI index, BMI index and obesity. Electronic data search was performed on platforms Pubmed and Google Scholar. Results: After reading and analyses, twenty-one articles with similar procedural criteria were selected, and among them only 6 were recognized as meeting the criteria of being completely accessible, having the selected keywords in their name, using the cephalometric analysis and BMI index and discussing the obese adults sleep apnea. In all the examined studies, it is proven that craniofacial morphology is a major anatomical risk factor for OSA. Conclusion: The role of the orthodontic specialists might be crucial in prevention of the development of obstructive sleep apnea, not only considering the orthodontic devices treament options, it can be especially important when obesity appears as a factor in the sense of informing and advising the patient and cooperating with other specialists who treat and prevent obstructive sleep apnea syndrome.

Abstract Objective The aim of this research was to examine the attitudes and perceptions of dentofacial aesthetics among different age groups. Materials and Methods The sample consisted of elementary-school students from the city of Sarajevo, Bosnia and Herzegovina, and their parents. This study included 314 subjects: 157 children and 157 parents. The children’s group consisted of 85 (54.14%) males and 72 (45.85%) females, aged 9 to 15 years. Statistical Analysis Descriptive statistics were used to determine frequency distribution and percentages for all variables. A chi-squared (x 2) test was used to determine the association between variables and a p-value < 0.05 was considered significant for all the differences and associations. Results For the dentofacial appearance with no teeth irregularity or with severe teeth irregularity, an analysis of variance (ANOVA) (post-hoc tests—Tukey’s HSD) indicated that the difference is not statistically significant (p = 0.06) relative to rank matching between all three subject groups. For dentofacial appearance with mild teeth irregularity, an ANOVA (post-hoc tests—Tukey’s HSD) showed statistical difference (p = 0.07) between the teenage group of subjects relative to pre-teenage group of subjects and adult group of subjects. Conclusion Attitudes about desirable and acceptable dental aesthetics differ in younger children compared with older children and parents. Ten years old children find good function with poor aesthetics more pleasing, while 14 years old children find aesthetics with bad function as more pleasing.

Retention is a phase of orthodontic treatment devised to keep the teeth in a correct position once the orthodontic treatment has been completed. There are three main characteristics that each ideal retainer is required to have: to keep the teeth in the correct position after orthodontic therapy, to be long lasting and resistant to mechanical damage, and to have no adverse long-term effects on periodontal tissue. Through a computer-based browsing through a number of databases (such as, e.g. PubMed and Google Scholar) we have found and analysed various articles used in this research. The inclusion criteria to be met were: an overall availability of a research paper, the requirement that these research papers are published in English, that these research papers were published in the period 2007-2019, the requirement that the research papers should involve clinically randomized studies and that their titles contain one of the predefined keywords. The database browsing that is based on the said keywords and carried out within the above time frame has resulted in finding 165 relevant articles. A complete set of the inclusion criteria were met by 8 published research papers, but 7 articles were analysed in the end. The selected articles have compared different types of fixed and mobile retainers, different times of wearing the retainers, the impact that the retainers had on the periodontium, and the acceptability of different retention protocols for patients. The conclusion of this research paper is that bonded retainers prove to be most effective in stabilising the position of the incisors, particularly the lower ones, but that their disadvantages include the reopening of the extraction space and the retention of plaque due to difficulties in maintaining oral hygiene. Vacuum-formed retainers appear to be more effective than Hawley retainers in retaining the position of the incisors, and patients have indicated that they are more acceptable to wear. Hawley retainers prove to be most effective in preserving a closed extraction space, but they do now show solid results with regard to other segments. Changes in the overbite, overjet, arch length, and anterior and posterior widths did not show any significant statistical differences in the different types of retainers.   Keywords: orthodontics, retention, stability, impact
