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.

Published: April 2019

SUMMARY
Introduction Need for orthodontic treatment is determined by the severity of specific malocclusion. Orthodontic indices are used to objectively present treatment needs. The most commonly used is the Index of Orthodontic Treatment Need (IOTN). The aim of this study was to determine the need for orthodontic therapy in 11 to 13 years old schoolchildren in Republika Srpska.
Material and Methods 1377 patients, 11 to 13 years old, were included in this study. The examinations were performed in elementary schools, using daylight, flat mirror and two-dimensional orthodontic caliper. Patients were ranked into 5 grades according to the Dental Health Component (DHC) and graded on a scale 1 to 10 for the Aesthetic Component (AC) of the IOTN index.
Results According to the Dental Health Component (DHC), 79.23% of patients needed orthodontic treatment. Little and borderline orthodontic need was present in 27.74% and 24.83% children, respectively, while severe need was present in 19.98% and 6.68% respectively. 20.77% of subjects did not need orthodontic treatment. In regards to the Aesthetic Component (AC) (face appearance related to orthodontic need) little or no treatment was needed in 91.42% of subjects while 6.42% were borderline and 2.16% of subjects had severe relation between orthodontic need and facial appearance.
Conclusion Due to the wide presence of orthodontic irregularities in schoolchildren 11-13 years old in Republika Srpska, it is important to introduce orthodontic indices in clinical practice in order to determine orthodontic treatment needs.

Published: April 2019

SummaryIntroductionDeep caries is a reversible process where caries lesion has affected bigger part of dentin and only thin layer of softened dentin that separates lesion from the pulp is remained. The objective of this study was to identify and determine serotypes ofAggregatibacter actinomycetemcomitansin teeth with deep caries lesions at the beginning of their treatment.Material and methodsClinical research included 29 patients of both genders, aged 16 to 40 and 45 permanent teeth with diagnosed deep caries lesions based on medical history, clinical and radiographic examination. After cavity preparation and removal of softened dentin, microbiological swab was taken from the bottom of the cavity. Swabs were disposed in special sterile micro tubes and stored at the temperature of −80°C until serotyping was done (determination of serotypes ofA. actinomycetemcomitansbacterium).ResultsIn one of the 3 samples two serotypes ofA. actinomycetemcomitans(b and c) were identified which is relatively rare finding, while in the second and third sample serotypes (a) and serotype (b) was identified, respectively.ConclusionIn the three samples the 3 serotypes were found (a, b and c) and one of the samples was carrying even two different serotypes, which is a rare phenomenon. For more serious epidemiological study ofA. Actinomycetemcomitansserotypes at the population level incomparably larger starting material is necessary, at least few hundred of samples.

Summary
Introduction Direct pulp capping is an important therapeutic method that has goal to provide formation of dentin bridge and healing process of the pulp. The aim of this study was to investigate the effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite on exposed dental pulp in Vietnamese pigs.
Material and Methods The study was conducted on 30 teeth of two Vietnamese pigs (Sus scrofa verus). On buccal surfaces of incisors, canines and first premolars, class V cavities were prepared with a small round bur and pulp horn was exposed. In the first experimental group (10 teeth) the perforation was covered with new nanostructural material based on calcium silicate systems (CS). In the second experimental group, the perforation was covered with compound of calcium silicate systems and hydroxyapatite (HA-CS) (10 teeth). In the control group, exposed pulp was covered with Pro Root MTA® (Dentsply Tulsa Dental, Johnson City, TN, USA) (10 teeth). All cavities were restored with glass ionomer cement (GC Fuji VIII, GC Corporation, Tokyo, Japan). Observation period was 28 days. After sacrificing the animals, histological preparations were done to analyze the presence of dentin bridge, inflammatory reaction of the pulp, pulp tissue reorganization and the presence of bacteria.
Results Dentin bridge was observed in all teeth (experimental and control groups). Inflammation of the pulp was mild to moderate in all groups. Neoangiogenesis and many odontoblast like cells responsible for dentin bridge formation were detected. Necrosis was not observed in any case, neither the presence of Gram-positive bacteria in the pulp.
Conclusion Histological analysis indicated favorable therapeutic effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite for direct pulp capping in teeth of Vietnamese pigs.

Summary
Introduction Local therapy of denture stomatitis (DS) associated with Candida species fungi infection usually involves the application of nystatin and miconazole. Due to the fact that these drugs may be less efficient against biofilm and possible resistance development, a new approach in the treatment includes the use of antiseptic agents.
The aim of the study was to compare clinical and microbiological therapeutic outcomes of antiseptic solution Listerine® and Daktanol® antifungal oral gel in the treatment of DS associated with Candida species fungi.
Material and Methods The study included 30 patients affected by DS, divided into the two treatment groups, control group (n=15) treated by Daktanol® gel and experimental group (n=15) treated by the antiseptic solution Listerine®. Successful treatment was evaluated based on palatal mucosa inflammation reduction classified according to the Newton classification and the difference in the number of fungal colony- forming units (CFU) isolated by smears before and after the treatment that lasted 14 days.
Results Reduction in inflammation intensity and fungal CFU number on palatal mucosa (p<0,01) as well as on denture base (p<0,01) were observed in both groups of subjects after the treatment.
Conclusion Antiseptic solution Listerine® and Daktanol® antifungal gel both reduced palatal mucosal inflammation and CFU number of fungi in mouth without significant differences among them. CFU number of fungi isolated from denture base was significantly lower after the treatment with Listerine® (p<0.05).
Case report. Endodontic treatment of lower molar in a patient with paraesthesia of inferior alveolar nerve – A Case Report
Authors: Jovanović-Medojević Milica , Nešković Jelena 
Published: April 2019

Summary
Root canal (endodontic) treatment is demanding and complex procedure. A variety of difficulties can occur in different phases of endodontic procedure. Complex anatomorphological tooth structure, curved canals, close proximity of lower molars and premolars to inferior alveolar nerve make endodontic treatment even more challenging. During endodontic treatment, an inferior alveolar nerve may become traumatized and symptoms may vary from mild neurosensory dysfunction to a complete loss of sensation in the innervation area of damaged nerve.
The aim of this paper is to present a clinical case of endodontic treatment of lower second molar with C-shaped root canal in a patient with paraesthesia of inferior alveolar nerve due to endodontic origin.

Authors: Nešković Jelena , Jovanović-Medojević Milica , Živković Slavoljub 
Published: April 2019

Summary
Introduction Development of inflammatory lesions or their persistence after primary treatment is considered endodontic failure. The reason for failure can be complex anatomy of the canal system and numerous iatrogenic factors.
The objective of this study was to analyze, clinically and radiographically, the causes of primary endodontic treatment failure and assess possibilities for retreatment of teeth with failed endodontic treatment.
Method The study included 79 teeth (36 multirooted and 43 singlerooted tooth) indicated for repeated endodontic treatment. Based on the radiographic assessment of the status of periapical structures, teeth were divided into two groups. The first group included teeth without periapical lesions, i.e. the healthy periodontal tissues (PAI score of 1 and 2) in which retreatment was required for prosthodontic reason due to the poor quality of obturation (28 teeth), and the second group included teeth with visible signs of periapical tissue damage (PAI scores 3, 4 and 5) (51 teeth). In both groups, quality of obturation, coronal sealing and the presence or absence of clinical symptoms was analyzed.
Results The most common radiographic finding of definitive obturation was short filling (65.8% of cases); “forgotten” canals (25.3%); non-homogeneous obturation with correct length (5.1%) and fractured instrument (3.8%). There was significant difference between healthy periodontal ligament and adequate restoration (P < 0.001). In 95% of patients with symptoms, changes in the periapical tissue were observed. Also, there was significant difference in the presence of symptoms after primary treatments, between the teeth with healthy apical periodontal tissue and teeth with periapical lesions (P = 0.019).
Conclusion The outcome of the root canal treatment is significantly affected by the quality (density) of obturation and the presence and quality of coronal restoration. In patients with symptoms there were changes in the periapical tissue.

Published: April 2019

Summary
Introduction Fear of dental procedures is one of the main reasons for oral health neglect. The first permanent molars are functionally very important. Dental anxiety may compromise their health as well as the health of all other teeth. The aim of the study was to determine dental anxiety level and the status of first permanent molars in healthy school aged children.
Methods This study included 105 students, 11 and 15 years of age, from two elementary schools in Foca (Bosnia and Herzegovina). Dental Anxiety Scale (DAS), questionnaire was used to determine the level of dental fear in patients. The status of first permanent molars was recorded using Klein-Palmer DMFT (decayed, missing, filling teeth) system. The number of healthy first permanent molars (with or without sealant) was registered as well.
Results More than one third of respondents involved in this study (33.3%), suffered from severe dental anxiety (DAS = 13–20 points). Statistically significant difference in answers to questions was not observed between respondents of different age but higher level of the fear was registered in girls compared to boys (p < 0.05). Less than 50% of all examined first permanent molars were healthy and sealed fissures were recorded in 9.4% of them. The percentage of decayed molars was about 11%, 7% extracted and 35% filled.
Conclusion Application of prophylactic measures is beneficial for dental health preservation. They are pain free and can be used to minimize fear by establishing dentist-patient relationship based on confidence.

Summary
Introduction Human organism can be identified through testing and analysis of DNA sequences. The most common source of DNA for analysis is blood, soft tissues, hair, bones and teeth. Teeth represent a tissue of choice for analysis in those cases where there is high degree of degradation of other tissues. Hard tooth structure provides protection and preservation of DNA molecules.
The aim was to investigate which group of teeth and dental tissue (pulp or hard dental tissues) has the greatest amount of DNA.
Material and method Forty-five extracted teeth were analyzed. In the first examination 30 teeth were divided into the three groups (10 teeth each): first group were incisors, second premolars and third molars. The teeth were measured before and after the procedure of DNA isolation using special scale with precision of 0.02-0.000005ng. The procedure included grinding teeth in a blender and DNA isolation using commercial kits (isolation with magnetic particles). For the second test 15 teeth divided into two groups were used. In the first group isolation of DNA molecules was performed from pulp tissue, and in the second group from hard dental tissues. The quantification of samples was done with Quantifiler® Duo DNA Quantification Kit by Applied Biosystems.
Results The greatest amount of DNA was obtained from molars (0.230011ng/μl/g) while the smallest amount of DNA was obtained from incisors and it was 0.06437ng/μl/g. In addition, the amount of DNA isolated from pulp tissue was significantly greater than that from hard dental tissues (pulp of molars obtained quantitatively the largest amount of DNA).
Conclusion Main tissue to be used for the isolation of DNA from a tooth is pulp, but in those cases when it is not present (endodontic treatment), hard dental tissues provide sufficient quantity of DNA for identification procedures. The group of teeth that provides the greatest amount of DNA is molars.
Combined surgical and orthodontic treatment of impacted second lower premolar – Case report
Authors: Simić Ivana , Domazet Tanja , Lečić Jelena , Ješić Jelena 
Published: April 2019

Summary
Impacted tooth is a tooth that has failed to reach occlusal plane, with 2/3 of completed root growth. There are various reasons for teeth impaction, however, lack of space for its emergence is considered to be the main reason. The most commonly impacted teeth are lower wisdom teeth, then upper wisdom teeth, upper canines, and less frequently lower premolars. There are only few studies that have addressed the issue of impacted lower premolars, their etiology, prevalence and treatment. The patient (22 years old) visited orthodontst for the lower jaw aesthetic teeth corrections, due to crowding. Ortopantomography analysis revealed impacted lower right second premolar that caused resorption of mesial root of the first molar. The treatment plan included tooth #46 extraction and placing orthodontic brackets on the impacted second premolar. The next step was extrusion of the tooth #45, its introduction to occlusal plane and orthodontic treatment resumption. Orthodontic treatment of impacted teeth with fixed orthodontic appliance provides excellent therapeutic results. The treatment success depends primarily on adequate planning, cooperation and joint work of oral surgery and orthodontic specialists.
Die forcierte Säkularisierung und ihre Nachwirkung. Das Bildungserbe der DDR am Beispiel Religiöser Jugendfeiern in Ostdeutschland
Authors: Handke Emilia 
Published: April 2019

Abstract
In the GDR, forced secularization led to a complex habitual posture of distance vis-à-vis explicit forms of religion and religious communitization. In order to initiate processes of religious communication and learning among families with no confessional affiliation, the church developed and shared responsibility for religious ceremonies for adolescents as an alternative to the secular »Jugendweihe« (coming-of-age-ceremony). These religious ceremonies were offered as a ritual in-between secular and religious traditions in order for the church to regain relevance for a broader part of the population.
Friedliche Revolution und Religionspädagogik – Bilanz und Plädoyer für einen erweiterten europäischen Referenzrahmen
Authors: Käbisch David , Simojoki Henrik 
Published: April 2019

Abstract
The term “Peaceful Revolution” (“Friedliche Revolution”) means the process of social, political, and religious change that led to the end of Communist rule 30 years ago in Germany as well as other European countries such as Poland, Czechoslovakia, and Hungary. How did this turning point affect religious education of the time? And how does it affect religious education today? With regard to the papers and interviews in the present journal we argue that the Peaceful Revolution and its relevance for religious education should be examined in a European reference framework. To achieve this, we systematically extend comparative approaches by using the methods of transnational history, such as connected history and global history. Finally, the article lines out didactical consequences of this approach.
