Summary The first record of scientific medicine in Serbia has been found in the early of 12th century. For centuries lifestyle, nutrition, natural environment, armies passing through, cultural heritage, and prejudice have affected healthcare in Serbia. Until 1820, Serbia has not had any educated doctor. Fourteen district physicians from 1839 and Dr. Karlo Beloni, to the last one, Dr. Selimir Djordjević – have spent part of their professional careers in Jagodina. All of them have had influence on raising health culture of Jagodina and its population and helped to overcome easily and quickly all existing diseases and epidemics. The Jagodina Hospital has been working without interruption for 147 years and represents one of the oldest healthcare institutions in Serbia.

Summary Introduction Separation (fracture) of endodontic instruments in the root canal during chemomechanical instrumentation is a complication that can compromise the final outcome of endodontic treatment. One of the most common factors that cause fatigue of endodontic instruments and consequent fracture is surface corrosion. The aim of this study was to investigate the ultrastructure of surface corrosion of endodontic instruments made of stainless steel and nickel-titanium after immersion in the most commonly used root canal irrigants. Material and Methods The study included 48 nickel-titanium and stainless steel endodontic hand files. All instruments were immersed in 5.25% sodium hypochlorite, 0.2% CHX and 17% EDTA. Surface corrosion was analyzed using a scanning electron microscope (SEM). Results Nickel-titanium instruments showed significantly higher susceptibility to corrosion after immersion in 5.25% sodium hypochlorite compared to stainless steel instruments (p<0,001). After immersion in 0.2% CHX corrosion damage was observed on both nickel-titanium and stainless steel instruments but the difference was not statistically significant (p=0.096). No corrosion was observed in both types of instruments after immersion in 17% EDTA. Conclusion The use of 5.25% NaOCl and 0.2% CHX as root canal irrigating solutions can cause serious corrosion changes on the surface of nickel-titanium and stainless steel endodontic instruments.

Summary Introduction In order to establish an accurate diagnosis and proper therapy planning in orthodontics, it is necessary to perform the analysis of transverse and sagittal dental arch development in relation to the facial type of the patient. The aim of this study was to determine sagittal and transverse parameters of dental arches in the population of Republika Srpska (Bosnia and Herzegovina) based on Schwarz analysis. Material and Methods Facial type was determined in 300 patients of both genders, aged 18 to 25, with class I occlusion. After taking impressions of the upper and lower jaw, cast study models were poured and used to determine basic sagittal and transverse parameters of dental arches. The obtained values were compared with the values defined by Schwarz in order to determine the existence of certain variations. Results Out of 300 subjects, 50.33% were dolichofacial, 30.76% were mesofacial and 19.00% were brachyfacial. The average values of anterior width, posterior width and height of dental arch in patients with all three types of face showed lower range of values compared to the values defined by Schwarz, who determined his values by examining the same parameters in the population of Vienna. These parameters did not show linear proportional increase with the increase of the sum of upper incisors, what is the case with the values defined by Schwarz. Conclusion The results of this study showed significant differences compared to Schwarz’s values. Modification of the size and shape of dental arch leads to changes in the appearance of patient’s face. Therefore, an individual approach during orthodontic diagnosis and treatment planning must be present despite the great importance of biometric standards.

Abstract Introduction The objective of this study was to compare two radiographic methods - digital intraoral and digital panoramic radiography in assessing marginal bone level around dental implants. The study also evaluated inter-observer and intra-observer reliability during repeated assessments. Material and Methods Marginal bone around 29 implants in 17 patients was assessed using standardized digital intraoral and digital panoramic radiographs. Two observers evaluated bone level by noting the thread at which marginal bone seemed to be attached at distal and mesial surfaces of the implants. The assessments were repeated after one week. Kappa statistics was used to evaluate agreement between assessments, observers, and radiographical methods. Results The agreement rate between digital intraoral and digital panoramic radiography was fair. Intra-observer agreement was very good, while inter-observer agreement was moderate. Conclusion Digital panoramic radiographs can be used to evaluate marginal bone level in patients with multiple implants and also to supplement intraoral radiographs. However, observer variability should be considered when comparing values from follow up studies for implant maintenance.

Abstract Introduction Self- assessment of oral health is simple, non-invasive and cost-effective method of collecting data that takes into account psychosocial aspects of oral health. The aim of this study was to investigate the effect of clinical factors on the self-perception of oral health in middle-aged patients in Republika Srpska (Bosnia and Herzegovina). Material and Methods The study included 126 subjects of both genders (34.1% male and 65.9% female) aged 24-54 years. Data were collected through questionnaires and clinical examination. Anonymous questionnaire contained questions related to socio-demographic characteristics of respondents. Clinical examination included teeth condition and the presence of prosthetic restorations. Self-perception of oral health was determined by one question. Results Bivariate analysis indicated significant effect of carious (p<0.001), missing (p<0.001) and filled teeth (p=0.022) but not the prosthetic status on self-perception of oral health. Correlation between the number of carious and missing teeth with self-perception of oral health was significant in regression analysis. Conclusion The number of carious and missing teeth had significant impact on self-assessment of oral health in studied population. Knowledge of effects of oral clinical variables on self-perception of oral health is very important to obtain clearer insight into the association between objectively and subjectively assessed oral health.

Abstract Introduction Vascular network of dental pulp is supplied through common and external carotid artery and terminal dental branches that supply each pulp tissue. Age related changes of pulp tissue influence pulpal vascularization as well. The aim of this study was to compare and correlate pulpal and common and external carotid artery blood flow in young and middle age individuals of general population. Material and Methods Two groups of 10 participants were included in the study, young (20-25 years) and middle age (50-55 years) group. Pulpal blood flow (PBF) measurements on intact right and left upper central incisors were performed using laser Doppler flowmetry (LDF) method. Carotid arteries blood flow was assessed using carotid ultrasonography. Results PBF levels were significantly higher in young (3.11±0.67 and 3.46±1.11, right and left upper central incisors, respectively) compared to middle age (1.93±0.47 and 2.30±0.64, right and left upper central incisors, respectively) participants (independent sample t test; p<0.05). There was no correlation between common and external carotid artery blood flow and upper central incisors PBF in young as well as middle age participants, for right or left side. Conclusion Absence of correlation between carotid arteries blood flow and PBF suggests that reduced PBF in middle age participants was probably not due to reduced blood supply from carotid arteries but it was result of age related changes at the level of pulpal blood vessels.

Abstract Introduction Calcium silicate cements can be successfully used for the treatment of root perforations due to their exceptional biological and sealing properties. The aim of this study was to test, using dye penetration method, marginal microleakage of newly synthesized nanostructured biomaterials based on calcium silicate system and hydroxyapatite after their application in interradicular perforation of extracted teeth. Material and Methods The study included 34 extracted human molars. Newly synthesized nanostructured materials: one based on calcium silicate system (CS), and the other one based on hydroxyapatite and active calcium silicate system (HA-CS) were tested. Mineral trioxide agreaggate (MTA; Angelus, Londrina, Brazil) was used as control. Marginal microleakage was evaluated using dye penetration test 6 months after the application of materials in experimentally prepared inter-radicular perforations in extracted human molars. Dye penetration was analyzed using light microscope at 30X magnification, a method of quantifying visual information in computer software for image processing (Adobe Photoshop CS5 Extended, version 12.0 x 32). The values were expressed in millimeters, and the results statistically analyzed using one-way ANOVA and Tukey post-hoc test (α=0.05). Results The shortest dye penetration was measured for calcium silicate system (0.44 mm), while slightly higher values were found for MTA (0.54 mm). Dye penetration for hydroxyapatite and active calcium silicate system (2.00 mm) was longer than for the other two materials (p<0.05). Conclusion The lowest marginal microleakage was observed in CS and was comparable to MTA. Microleakage in HA-CS was significantly higher than CS and MTA.

SUMMARY Bioactive glasses are often used nanomaterials in tissue engineering of bone and soft tissue. Many newly synthesized materials for applications in medicine and dentistry are based on these bioactive substances. Bioactive glass is usually used as a scaffold or as an implant coating on implants and it allows fast formation of apatite layer with positive effect on osteoblasts proliferation. These biomaterials play an important role in dentistry and endodontics. This study is mostly part of the monograph titled “Nanomedicine, the Greatest Challenge of the 21st Century”, that for two years has received attention from professional and scientific community in various fields. Information presented in this paper highlight structural characteristics of bioactive glasses that have a significant role in bone tissue engineering KRATAK SADRŽAJ Bioaktivna stakla su nanomaterijali koji se dosta često koriste u inženjerstvu koštanih i mekih tkiva. Brojni novosintetisani materijali za primenu u medicini i stomatologiji se baziraju upravo na ovim bioaktivnim supstancama. Bioaktivno staklo se najčešće koristi kao skafold ili prevlaka na implantatima, i omogućava brzo formiranje apatitnog sloja, odnosno povoljno utiče na proliferaciju osteoblasta.

SUMMARY Introduction Malocclusion is common in children and it has great influence on the quality of life of patients. The aim of this study was to determine the prevalence of malocclusion among 11-13 years old children in the municipality of Foca in Republika Srpska. Material and Methods The study included 81 respondents, 11-13 years old. It was conducted in elementary schools in the municipality of Foča. Respondents underwent clinical examination, alginate impressions of upper and lower jaws were taken and study models analyzed. To determine malocclusion (crowding, spacing, cross bite, deep bite, open bite and occlusion class as per Angle) ICON index (Index of Complexity, Outcome and Need) was used. Results The results showed that 17.3% of respondents had spacing between teeth, 80.2% crowding, 23.4% cross bite, 29.6% deep bite while open bite was present in 2.4% of patients. Occlusion II/1 class by Angle was present in 38.3% of respondents, II/2 class in 12.3% of respondents, Class I occlusion in 40.7% of respondents and III class was found in 2.4% of respondents. Conclusion There was high prevalence of malocclusion in the examined children. It is necessary to implement prevention programs, early treatment of dental caries, prevent premature tooth loss as well as measures of interceptive orthodontics in order to reduce frequency of malocclusion KRATAK SADRŽAJ Uvod Ortodontske nepravilnosti su različito, ali dosta često, zastupljene kod dece i u velikoj meri utiču na kvalitet života pacijenata.
