Oral health is an integral part of general health and can significantly affect the quality of life [1, 2]. The prevalence of oral diseases is high and their impact on an individual and a community is significant [3]. Dental caries is one of the most common chronic diseases today, occurring in 60-90% of school children and many adults [1]. It should be noted that caries in children has not been completely eradicated, but has been put under control only to a certain extent [4]. Recent research has shown a significant improvement of dental health and decrease in caries prevalence in all age groups. However, dental caries is still the most frequent disease in adolescence [5]. Incomplete maturation of enamel, increasing number of surfaces susceptible to caries, external factors such as diet, poor oral hygiene and other social factors may also contribute to increased risk for caries in adolescents [6, 7]. In addition to dental caries, adolescence is critical period for periodontal health. Epidemiological and immunological data have indicated that irreversible damage of periodontal tissue begins in late adolescence and early youth [8]. Frequent occurrence of gingivitis in adolescents as compared to pre-pubertal children and adults has also been noticed. The aim of this study was to determine the prevalence of caries and gingivitis in adolescents age 15 and 17-18 years in the municipality of Foca, Republika Srpska. MATERIAL AND METHODS The final year students from all five elementary schools (two urban and three from suburbs) and the only high school in the municipality of Foca were included in this cross-section study. All students present at the school on the day of the clinical trial were included in the study. There were 135 students (age 15) of primary school (the ninth grade) and 217 students (age 17-18) third and fourth grade of high school. Clinical examination was conducted in classrooms using dental mirrors, dental and periodontal probes under natural light and artificial lighting of the room. The incidence of dental caries was determined using DMFT index and its components (D-decayed, M-missing, F-filled teeth) as recommended by the World Health Organization (WHO) [9]. Periodontal tissue condition was determined using gingival index (GI) by Löe and Silness.

Summary Introduction Caries and orthodontic anomalies in school-age children lead to disturbed aesthetics, oral functions (chewing, swallowing, and speech), predisposition to trauma and the onset of periodontal diseases. The aim was to assess dental health and frequency of orthodontic anomalies in children aged 8-9 years in the municipality of Foča. Methods The research was conducted in the primary school Sveti Sava in Foča, where the total of 112 children age 8-9 years were examined. An informed consent was obtained from parents and school director for each student. Dental examination was performed using standard dental method, a mirror and a probe under artificial lighting. Children received instructions on proper nutrition, oral hygiene, tooth protection and elimination of bad habits. Results Among 112 examined boys and girls of selected ages, very high person caries index (PCI) was found (78.57%). A total of 548 caries affected teeth were found (boys 331 (24.62%), girls 217 (16.14%) (p <0.05)). Fifty-nine children had caries lesions on permanent teeth (boys 39 (2.9%), girls 20 (1.5%) (p <0.05)). Sagital abnormalities of the bite were present in 39 (34.82%) children, while 38 (33.92%) anomalies were related to vertical bite irregularities, 10 (8.92%) of them had open bite and 28 subjects (25%) had deep bite (p> 0.05). Conclusion Large number of teeth was affected with caries lesions (548) in eighth-year-olds, while orthodontic anomalies, mostly sagital abnormalities of bite were found in 39 subjects.

Introduction.Epulis is a change in gingival tissue that occurs under the influence of chronic irritation. Histologically, there are several different types of epulis. Fibrous epulis is benign tumor of gingiva that most often occurs in interdental papilla area as a result of local irritation (inadequate restorative fillings, carious teeth, subgingival deposits or the combination of them). The aim of this paper is to present a clinical case of fibrous epulis. Case report.A 25-year-old girl reported to the Specialist Center for Dentistry in Foca. Clinical examination revealed a gingival tissue enlargement in the area of the upper jaw central incisors with speech and chewing function disturbances. Intraoral examination revealed a change above the level of gingiva, reddish-pink in color with smooth surface texture and soft consistency. The size of the change was 1 x 1.5 cm. It was connected to the interdental gingiva between teeth 12 and 21 by a narrower base. Clinically, a significant amount of soft and hard dental deposits surrounded the remaining teeth. Remaining gingiva was swollen, red, bleeding on provocation. The anamnesis did not confirm the presence of other acute and chronic diseases. The patient was not pregnant. She was informed about clinical condition assessment, as well as possible therapeutic procedures. Our patient was treated with non-surgical periodontal therapy and surgical excision of the enlargement. After histopathological examination of the removed tissue, the diagnosis was made: "Fibrous epulis cum ulceration". Conclusion.Clinical examination is insufficient for definite diagnosis. Therefore, a histopathological examination of the tissue is mandatory for fibrous epulis definite diagnosis. Treatment of choice is surgical excision of the enlargement and removal of predisposing factors to avoid recurrence.

This paper presents the analysis of two-word terminological phrases within distribution system, the specifics of word formation as well as the aspects of interrelation between expert terminology and general vocabulary. Certain lexical and semantic principles in power system terminology in Serbian were pointed out through the analysis of paradigmatic relations, as well as the variation i.e. consistency of their phrasal form upon translation into English. Cross-language influences are particulary discussed, especially foreign origin terminology penetration in the Serbian language.Research results indicate that analysed terms used in its syntactic form can hardly be applied outside the terminology circle which they belong to, given its precise reference to a specific phenomenon within the power system, the mode of operation of a specific device or the entire system, an individual part or the wide range of components used in the system, the position or different circumstances peculiar to this profession.
