Stomatolo?ki Glasnik Srbije , 2006, DOI: 10.2298/sgs0604229s
Abstract: Caries is the most frequent oral disease in all age groups. Aim: The aim of this study was to determine dental status and caries prevalence in adolescents in the Eastern Bosnian region, in Fo a municipality Materials and methods: The study comprised 300 pupils of secondary schools, of both sexes and aged between 15 and 18 in Fo a municipality. Dental check-up was conducted by a single dentist using daylight, dental mirror and dental probe. Caries prevalence was analyzed using the DMFT index. Results: Results showed that the dominant components of DMFT were filled (51.7%) and decayed teeth (36.8%) while extracted teeth were least frequent (11.8). Initial caries was observed most frequently in upper (48%) and lower (39.7%) molars and least frequently in lower anterior teeth (8.4%). Deep caries lesions were most often found in upper (35,7%) and lower (33.3%) molars and rarely in lower anterior teeth (3.3%). Conclusion: Adolescents in Eastern Bosnia (Foca municipality) have great number of carious and unrestored teeth and, therefore, the implementation of primary dental healthcare system is necessary as well as looking for a solution to this problem.

Stomatolo?ki Glasnik Srbije , 2007, DOI: 10.2298/sgs0702089s
Abstract: Introduction: Caries is one of the oldest and most common human diseases and, as such, attracts attention of scientists and researchers worldwide. Aim: The aim of this study was to determine caries prevalence in the students of Dental and Medical Schools in Bosnia and Herzegovina. Materials and Methods: The study was conducted at School of Dentistry in Foca and included 340 students, 18-25 years of age. Caries prevalence was analyzed using DMFT index and its components. Results: The average DMFT values in the examined population of students was 12.8±4.7 with only one student with DMFT=0. Obtained results revealed that upper molars were most frequently affected by initial as well as deep caries (30.4%, 15.3% respectively) while anterior teeth were least affected (5.3% and 0.3% respectively). The greatest number of students had 1-3 amalgam restorations. Maxillary teeth from both anterior and posterior segments were most frequently restored with esthetic materials. DMFT index analysis showed that lower molars were among the most often extracted teeth (48.2%). Conclusion: High DMFT index values in the examined population is the results of inadequate organisation of dental healthcare service and inadequate preventive measures in specific socio-economic and medical conditions. .

Abstract: Introduction. A significant change in frequency and characteristics of oral diseases in developed countries has been detected recently. The aim of this study was to determine the dental status of teeth in adults in the eastern region of Republika Srpska and to determine possible difference in the prevalence of dental diseases according to the demographic characteristics. Materials and Methods. The study included 182 respondents aged 35-44 years and 185 respondents aged 65-74 years, selected randomly from four municipalities in the eastern region of Republika Srpska. Dental examinations were conducted according to the standards and criteria developed by the World Health Organization. Dental status, determined by DMFT index, was analyzed according to the gender and place of residence (urban/rural). Results. The mean DMFT index was 20.2 in the age group 35-44 years and 28.5 in subjects aged 65-74 years. The dominant component of the index in both studied groups was the number of extracted teeth. For subjects aged 65-74 years from rural areas a significantly higher DMFT index as compared to the residents in urban regions (p<0.05) was reported. Females had fewer caries lesions (p<0.05) and greater number of restored (p<0.01) teeth as compared to male respondents in the age group 35-44 years. On the other hand, in the older population study group, females had lower number of restored teeth (p<0.01), higher number of missing teeth (p<0.01) and higher DMFT index (p<0.2001) as compared to males. Conclusion. The present results indicate that the prevalence of caries in adults in the eastern region of Republika Srpska is very high.

Abstract: Introduction. Dental caries has been one of the oldest but still one of the most common oral diseases in humans. Even though it has been almost eradicated in developed countries due to increased fluoride use, adoption of proper oral hygiene habits and systematic implementation of preventive programs, caries remained one of leading oral diseases in developing countries. Epidemiological data about the prevalence of caries is very important for prediction of need for dental care, number of dental care providers as well as financial aspect. The aim of this study was to determine dental status and indicate dental treatment need in adults of the municipality of Foca, Republika Srpska (Bosnia and Herzegovina). Material and Methods. The study included 244 randomly selected residents (131 males and 113 females) from the municipality of Foca which were divided into three age groups: 20-29, 30-39 and 40-49 years. Dental status and need for dental treatment were determined in accordance to the criteria and methodology of the World Health Organization. Results. Mean value of DMFT index was 12.7 for the first age group, 16.4 for the second and 20.5 for the third age group of respondents. Dominant components in the first group were restored and carious teeth while in the third age group number of extracted teeth dominated. Also, in the third age group of respondents need for one and two or more surfaces fillings was significantly lower (p<0.01), but need for removable dentures was significantly higher (p<0.01) as compared to other two groups. Conclusion. These results indicated high value of DMFT index in adult population of the municipality of Foca.

Abstract: Introduction. It has been known that periodontitis is one of the most common oral diseases in patients having diabetes mellitus (DM). The aim of this study was to examine the influence of glycosylated hemoglobin (HbA1c) level and the level of oral hygiene on periodontal status of patients suffering from DM. Material and Methods. The research included 50 people with type 2 DM randomly selected. Based on values of HbA1c, patients were divided into two groups: well controlled DM (HbA1c≤8.5%) and poorly controlled DM (HbA1c>8.5%). Patients with poorly and well controlled DM were further grouped into subgroups depending on the level of oral hygiene. For each patient, during the clinical examination, periodontal parameters were determined: plaque index (PI), sulcus bleeding index (SBI), the level of junctional epithelium (LJE) and periodontal pocket depth (PPD). Results. The results showed that patients with well controlled disease and good oral hygiene had lower values of the examined periodontal parameters (SBI and PPD) then patients with poorly controlled DM and worse oral hygiene (p<0.01 for SBI, p<0.05 for PPD). Conclusion. The results of this study indicate the important role of oral hygiene for periodontal status of patients with DM.

Abstract: Introduction. The aim of this study was to determine the prevalence of dental caries and analyze the status of teeth in relation to sociodemographic factors and habits and behavior related to oral health among adolescents in the eastern region of Republika Srpska. Material and Methods. The study included 212 adolescents (71 males and 141 females) age 16-18 years. Information about sociodemographic characteristics, oral hygiene habits and behaviors related to oral health were collected using a questionnaire. The prevalence of dental caries was determined by applying the DMFT index and its components (D - decayed, M - extracted, F - filled teeth). The status of teeth was analyzed in relation to socio-demographic variables, oral hygiene habits and behavior related to oral health. Results. The mean DMFT value of examined population was approximately 8.6. A significant difference in the status of teeth of adolescents was reported in relation to the place of residence and oral hygiene habits - brushing frequency and the use of dental floss. A significant difference in the caries prevalence was recorded depending on the elapsed time from last visit and reasons for visiting dentist. Conclusion. The results suggested that the place of residence, oral hygiene habits and behavior related to oral health influenced the status of teeth of adolescents in the eastern region of Republika Srpska.

Abstract: Introduction. The main goal of obturation is prevention of reinfection of the root canal system and consequently appearance of periapical lesion. Epidemiological studies have confirmed high prevalence of periapical lesions in endodontically treated teeth with inadequate root canal fillings. The aim of this study was to assess the quality of root canal fillings in teeth treated at students’ practical sessions. Iatrogenic errors during endodontic interventions were also assessed. Methods. Two hundred dental records of the patients treated by students in the study program Dentistry at the School of Medicine in Foca during the academic year 2010/2011 were randomly chosen. The length and homogeneity of the fillings or the presence of iatrogenic errors were recorded. A root canal filling was considered adequate if it had correct length and homogeneity in the absence of iatrogenic errors. Two students’ curricula V1 and V2 were evaluated for the treatment outcome. Results. Out of 128 endodontically treated teeth, adequate length of the canal filling to the physiological apex was observed in 57% of teeth, homogeneity in 78.9%, while both of these criteria were satisfied in 66 teeth (51.6%). Better quality of root canal fillings was achieved by students of the study curricula V2 and the difference between these two programs was significant (p<0.05). Better quality of root canal fillings in both study programs was recorded for incisors and canines as compared to premolars. Conclusion. The quality of endodontic treatment performed by students was considered adequate in 51.6% of cases. The type of curriculum for endodontic course had a significant impact on the quality of endodontic treatment performed by students.

Abstract: Introduction. As a systemic disease, diabetes mellitus may lead to several complications affecting both the quality and the length of life. While periodontal disease is one of the major oral health problems in patients with diabetes, reports of an increased risk of dental caries among diabetics are controversial. Objective. The aim of this study was to investigate oral health status in patients with diabetes mellitus type 2 in relation to metabolic control of the disease. Methods. The study included 47 randomly sampled diabetics patients, divided into two groups; those with poorly controlled diabetes (glycosylated haemoglobin - HbA1c ≥9%) and those with better controlled diabetes (HbA1c<9%). All patients completed a questionnaire about their medical and oral health. Decayed, missing, and filled teeth (DMFT) and plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment loss (CAL) were recorded. Results. The patients with poorly controlled diabetes had a significantly higher number of tooth caries compared to those with better controlled diabetes (6.5±4.3 vs. 4.3±2.9; p<0.05). Of periodontal parameters, only PPD was significantly higher in the patients with poorly controlled diabetes than in those with better controlled diabetes (5.8±0.9 vs. 5.2±0.8; p<0.05). DMFT index, PI, PPD and CAL exhibited positive correlation only with patients' age. Conclusion. The study indicates that there is a relationship between poor control of diabetes and caries, and periodontal disease.

Abstract: Growth of HeLa cell culture in vitro was examined, in different concentrations of four resin materials extracts which are used for denture base making. Cell growth was evaluated through density, invert microscope counting, after 48 hours of incubation and through metabolic MTT test after 3 days. Extract was taken by incubation of material sample on 37 °C in physiological solution, for 72 hours. It is given weaker growth, reduction of adherent cells count and phenotypic changes of cells grown in presence of extracts from all examined materials. Extracts of examined materials increase number of phyllopodic extensions on dose dependent manner.

Acta Medica Medianae , 2012,
Abstract: The use of acrylic denture base resins is widely spread in dental practice. They belong to the group of biomaterials due to their role of morphological and functional substituent in the mouth. However, clinical practice has shown that some toxic ingredients of these materials may lead to adverse local and even systemic changes. The aim of the study was to evaluate cytotoxic effect of various denture base resins on cell culture using direct contact test. The effect of four different acrylic materials on HeLa cell structure was evaluated. Upon light microscopy analysis, MTT test was performed without previous removal of material samples. The obtained values of MTT indicate that cell proliferation is dependant on the type of acrylic denture base resins. Cold polymerization denture base resins showed mild inhibitory effect on the cell culture growth. The signs of toxicity were not observed in heat polymerization denture base resins.
