Background/Aim: The aim of the research is to assess the psychosocial impact of malocclusion, to determine the relationship with the degree of need for orthodontic treatment, and to assess the influence of gender on this relationship in adolescents. Material and Methods: A total of 100 subjects, aged 12 to 18, participated in the research. The subjects had no previous orthodontic treatment. The assessment of the need for orthodontic treatment was performed using the Index of Orthodontic Treatment Need (IOTN), namely the Dental Health Component (DHC) and the Aesthetic Component (AC). The psychosocial impact of dental aesthetics was assessed using the PIDAQ questionnaire. Results: The total PIDAQ score, as well as its 4 subclasses, dental self-confidence, psychological impact, social impact and aesthetic concern have a positive correlation with the categories of the IOTN. The psychosocial impact of dental aesthetics is similar in boys and girls, except that girls showed a slightly greater aesthetic concern due to the presence of malocclusion. Conclusions: The present malocclusion has a psychological and social impact on the individual, but it also negatively affects his dental self-confidence and aesthetic concerns. The results of the PIDAQ questionnaire can guide the orthodontist to the patient's basic problem and thus provide guidelines for orthodontic treatment.

Background/Aim: The objective of this research was to evaluate the level of oral hygiene, the prevalence of caries, and the condition of the soft tissues in children and adolescents referred for their first orthodontic examination. Material and Methods: The research was conducted at the Department of Orthodontics of Sarajevo University - at the Faculty of Dentistry with the Dental Clinical Center. A total of 300 patients with mixed and permanent dentition who were referred for their first orthodontic examination were included in the study. The patients were offered to sign a Letter of Informed Consent for this study. All patients were assigned a Decayed, Missing, and Filled Teeth (dmft/DMFT) index. Periodontal indices were evaluated on all first permanent molars and all permanent central incisors. The periodontal indices included the determination of PI,CI,GI, PBI. Results: The results were processed with the application of standard statistical methods, by using the SPSS computer program for statistical analyses (SPSS-Statistical Package for Social Sciences) Version 21.0. The results of this study show a high dmft and DMFT indices in patients referred for orthodontic examination. The dmft index value in the respondents with mixed dentition was 3.0 (1.0 - 6.0). The DMFT index value in the respondents with permanent dentition was 4.0 (0.0 - 6.0), while in the respondents with mixed dentition, it was 1.0 (0.0 - 3.0). Our research also shows that out of 300 patients referred to an orthodontist for their first orthodontic examination, 250 of them (83.33%) have demonstrated an increased value of the Plaque index. Conclusions: The results of this research should be peculiarly alarming for pedodontists and general dentists, cautioning them to implement caries prevention measures more intensively and make referrals to an orthodontist only in case of those patients who have been cured previously.

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.

The aim of this study was to assess awareness among the students of the Faculty of Dentistry of the University of Sarajevo of the occupational health risks associated with dental profession. The research was conducted among the dental students of all years of study at the Faculty of Dentistry of the University of Sarajevo, by using a tailor-made survey questionnaire. The questionnaire was completed by 446 students. Results: 92% of students believe that dentistry is a profession that involves a high level of risk for the outbreak of occupational diseases. Students believe that practicing dentistry can most often lead to various infections (70%) and vision impairments (64%), and that the most common potential causes of occupational diseases are poor positioning and incorrect body posture during work (88%) and infections (78%). When asked whether the occupational diseases among dentists are preventable, 89% of students gave an affirmative answer, and pointed to the requirement to use Personal Protection Equipment – PPE (94%) as the most important measure for the prevention of occupational diseases among dentists. The results of the survey show that the students of dentistry at the Faculty of Dentistry of the University of Sarajevo have reached a certain level of awareness of the health risks that are associated with their future profession. The students have taken a largely identical view that dentistry is a profession that involves a high level of risk for the development of occupational diseases.

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

Objectives The development of third molars can be helpful in dental age estimation of adolescents and in early adult period. We tested the repeatability and accuracy of the three dental age radiographic methods (Olze, Demirjian and Solari and Abramovitch) and evaluated which method is more useful. We also aimed at testing to find the correlation of estimated dental and chronological age by these three methods. Material and methods The orthopantomographs (OPGs) of 1007 individuals (8 - 25 years) were divided into two groups (cca 500 OPGs) - one group of OPGs has been presented with all four third molars, while another one was registered with third molar/s hypodontia. And all of OPGs were assessed, to verify the three methods (Olze, Demirjian and Solari and Abramovitch) for age estimation based on third molar development. Results There was a high Spearman's correlation coefficient between stages of development of wisdom tooth and chronological age of subjects by all these three methods. Conclusion We may recommend using third molars for assessing the dental age by Olze, Demirjian and Solari and Abramovitch dental method as well, on Bosnian and Herzegovinian population.

Introduction : A method for age estimation, based on measurements of projections of open apices and heights of developing permanent teeth on orthopantomograms (OPTs), was presented by Cameriere in 2006 and adopted European formula was presented in 2007. Aim : This cross-sectional study tested the accuracy of Cameriere’s European formula on a sample from the City of Sarajevo, Bosnia and Herzegovina. Materials and methods : A final sample of 560 OPTs of 305 girls and 255 boys aged 8 to 14 years was obtained. The sample was collected at the Department of Orthodontics, School of Dental Medicine at the University of Sarajevo (SFUNSA). Dental age was compared to chronological age and mean absolute error (MAE) was calculated. Intra-rater and inter-rater agreement of the evaluated variables were calculated. Results : The dental age was underestimated when compared to chronological age, precisely, mean underestimation was -0.14 years in girls and -0.17 years in boys. The values of MAE were 0.62 years in girls and 0.56 years in boys. The greatest error was found for the 14-year old group; DA was -1.04 years and -0.70 years in girls and boys respectively. Conclusion : Our results showed that Cameriere’s European formula might be a useful tool for age estimation in children from Bosnia and Herzegovina under the age of 14 years.
