Summary Introduction The most frequent oral disease in children is tooth decay. The aim of this study was to determine the health status of primary teeth in 6 year-old children. Material and method The study included 203 children of both genders living in the territory of Podgorica municipality. Only children whose parents gave consent were included. The parameters used for assessing oral health condition were: number of decayed, missing, and filled teeth due to caries (dmft) and Significant Caries Index (SiC). One dentist clinically examined all respondents in accordance with methodology and criteria of the World Health Organization (WHO). Results The average value of dmft in 6-year-olds in Podgorica was 4.9. On average, 80.3% of examined children had dental decay. The SiC Index was 8.3. Among examined children, 12.3% had at least one tooth with fissure sealant. In dmft structure dominated untreated decay (92.6%). Conclusion Results showed high prevalence of primary teeth decay in 6 years old children, indicating the absence of preventive measures and programs in Montenegro.

Summary Introduction Oral diseases during pregnancy are an important reason for enhanced dental care of this vulnerable population. The aim of this study was to determine the degree of oral health awareness among pregnant women and examine their oral hygiene habits, attitudes and behaviors in relation to the professional qualification. Material and methods The study was conducted in Foča, East Sarajevo, Bijeljina and Pale (Republika Srpska, Bosnia and Herzegovina). A total of 198 respondents voluntarily filled an anonymous survey, specially created for this research. Results In addition to toothbrush and toothpaste, 39.8% of pregnant women did not use any additional oral hygiene resources. When brushing their teeth, 60.1% of pregnant women had bleeding gums. Also, 54.1% of pregnant women visited dentist, while 34.3% did not. Obstetrician did not advise 69.7% of respondents that the should visit dentist during pregnancy. Furthermore, 80.8% of pregnant women thought that they were more susceptible to pregnancy caries, and 29.6% of them thought that caries is disease that cannot be prevented. Respondents with university education understood that minerals from the mother’s teeth were not lost during pregnancy, which was statistically significant compared to pregnant women with secondary education. Conclusion The level of oral health awareness of pregnant women is low. It is important that all women perform regular dental examination during pregnancy, as they will receive useful information from their dentist how to prevent oral diseases.

Summary Health care has witnessed considerable progresses toward quality improvement over the past two decades. More precisely, there have been global efforts aimed to improve this aspect of health care along with experts and decision-makers reaching the consensus that quality is one of the most significant dimensions and features of health system. Quality health care implies highly efficient resource use in order to meet patient’s needs in terms of prevention and treatment. Quality health care is provided in a safe way while meeting patients’ expectations and avoiding unnecessary losses. The mission of continuous improvement in quality of care is to achieve safe and reliable health care through mutual efforts of all the key supporters of health system to protect patients’ interests. A systematic approach to measuring the process of care through quality indicators (QIs) poses the greatest challenge to continuous quality improvement in health care. Quality indicators are quantitative indicators used for monitoring and evaluating quality of patient care and treatment, continuous professional development (CPD), maintaining waiting lists, patients and staff satisfaction, and patient safety.

Summary Introduction The aim of the study was to establish the association between oral health and malnutrition in people over the age of 65. Material and Methods Cross-sectional study included 146 respondents residing in gerontology center, and 300 respondents who lived in their own homes or with their families. Nutritional status was evaluated using the Mini Nutritive Scale and standardized questionnaire. Dental status was evaluated by clinical examination using inspection method. The presence and absence of teeth was evaluated in each dental arch (third molars were not taken into consideration). Also, the presence of prosthetic restorations (total and partial dentures) was noticed without analyzing their adequacy and functionality. Self-assessment of health with categorical components assessed the overall health status. The research was conducted in 2018. Results Most of respondents who had malnutrition or were at risk of malnutrition had worse dental status; they were completely or partially edentulous. There was high statistically significant difference in dental status of the upper (χ2=47,797; p < 0,001) and lower jaw (χ2 = 66,680; p < 0,001). The number of lost teeth had an impact on self-assessment of general health (χ2 = 47,270; p < 0,001). Conclusion Oral health status in elderly people had significant influence on nutritional status.

Summary Introduction Efficient cleaning and canal design present a basic precondition for successful endodontic treatment. The aim of this study was to evaluate, using SEM analysis, the efficacy of cleaning the apical third of the canal with one instrument in both reciprocating motion and full rotation systems. Materials and methods Thirty (30) single-rooted teeth (upper incisors), extracted due to periodontal reasons, were used and selected in 2 groups. In the group 1, instrumentation was done with a single instrument UNICONE with reciprocal movements (MEDIN, Czech Republic), while in the group 2, a single instrument XPS endo SHAPER (XPS) (FKG, Dentaire, Swiss) with full rotation was used. 2% solution of NaOCl and 17% EDTA solution were used as irrigation agents in both groups. SEM analysis of smear layer in the apical third was done at standard magnification of 1000x and presented on a scale of 1-5. Results showed mostly clean canal walls and no smear layer in the apical region in both tested groups. Canal walls were somewhat cleaner after using UNICONE with reciprocal movements (80%) compared to the canals instrumented with XPS ENDO SHAPER (76%), but this difference was not statistically significant. Conclusion Single-file NiTi systems did not remove smear layer completely, but provided efficient cleaning in the apical part of the canal. UNICONE file with reciprocal movements was somewhat more efficient in removing smear layer compared to the full rotation XPS ENDO SHAPER file.

Summary Introduction The main objective of endodontic treatment is to eliminate infection from root canal and prevent reinfection by three-dimensional hermetic obturation of the canal system. Endodontic failure can occur due to inability of complete control and elimination of infection from the root canal. The aim of this study is to investigate, by PCR technique, microbiological status of previously endodontically unsuccessfully treated teeth immediately after the removal of obturation material. Material and Methods The analysis included 30 teeth indicated for endodontic retreatment. After removing previous root canal filling material, the bacteriological sample was taken by sterile instrument (# 15) and paper points. Standard PCR technique was used to analyze the incidence of E.faecalis, P.micros, P.intermedia, P. endodontalis and A.actinomycetemcomitans. Results Positive bacteriological findings were registered in 80% of cases, while bacteria were not identified in 20% of all samples (all taken from the root canals without significant changes in periapical tissue). From 24 canals with identified bacteria, 17 had affected apical periodontium. The most dominant microbe in root canals with positive bacteriological finding was E.faecalis (83.3% of the canals) and P.intermedia (75%). In case of teeth with chronic periapical changes, the most common was E. faecalis (94%) and P.intermedia (82.3%). Conclusion The presence of periapical lesions significantly affects microbiological status of endodontically treated teeth. The presence of bacteria was confirmed in most teeth with periapical lesions, while the most frequently identified bacteria were E. faecalis, P.intermedia and P.micros.

Summary Introduction The aim of the study was to quantify and compare fluoride release from four different glass ionomer cement products (GICs). Materials and Methods Standardized disk-shaped samples (5x2mm; n=5/group) of GIC restorative materials: conventional (Fuji IX, GC Corp., Japan), resin-modified (Fuji II LC, GC) and hybrid glass ionomer cement (Equia Forte, GC) and a conventional GIC liner/base material (Alfagal, Galenika, Serbia) were tested for fluoride release up to 21 days postsetting. Each sample was immersed in 5 mL of fresh deionized water during each time interval. Universal microhybrid composite (Filtek Z250, 3M EPSE, USA) and adhesive (Adper Single Bond, 3M ESPE) were used as negative controls. Fluoride release was measured using an F-selective electrode (Cole-Parmer, USA) and an ion meter (Oakton 700, Cole-Parmer, USA). Data were statistically analyzed using one-way ANOVA, regression and correlation analysis at 0.05. Results The highest total fluoride release was measured from Alfagal (386±61 ppm/g), and significantly less from Equia (188±29 ppm/g), Fuji IX (143±11 ppm/g) and Fuji II LC (104±14 ppm/g) (p < 0.05). All GICs showed the highest fluoride release during the first 24 hours post-setting. After 3 days, fluoride release slowed down reaching a plateau for all materials. Regression and Pearson correlation analysis showed significant inverse relationship between fluoride release and sample mass and density (p<0.001). Conclusion Of the three GICs indicated for use as restorative materials, Equia Forte released the highest fluoride concentration. Fluoride release was material and density dependent, with higher release occurring from lower density GICs.

Summary Introduction In everyday clinical practice, we often encounter a lack of space for placing all the teeth present into dental arch; therefore it is often recommended to extract teeth within orthodontic treatment. In clinical practice, the most commonly used methods of closing space after are elastic chains and NiTi closed spiral springs. The aim of this paper was to compare postextraction space closure speed using two different sliding mechanisms, NiTi closed coil springs and elastic chains within treatment with fixed orthodontic appliances. Material and Method The total sample in this study consisted of 46 postexstraction spaces in 23 patients indicated for the extraction of first premolars using treatment with fixed orthodontic appliances. Two sliding mechanisms, NiTi closed coil spring and elastic chains were applied to postextraction space closure. Postextraction spaces were monitored for 4 months with appointments every 4 weeks. During appointments mechanisms were activated and digital caliper was used to measure the width of the postextraction space. Results The results showed that NiTi closed coil springs method achieved greater reduction in postexstraction space (3.94 mm) while with elastic chain method the closure of 3.10 mm was achieved. The total difference between these two methods in the observed period was 0.84mm and no statistically significant difference was found (p> 0.05). The lowest value for NiTi closed springs was 2.19 mm, while for the elastic chain it was 1.29 mm. The best postextraction space closure was 5.70 mm and it was completed using NiTi closed springs while for elastic chain the best value was 4.80 mm. Conclusion: NiTi closed coil springs lead to faster closure of postextraction spaces in relation to elastic chain. Since this difference is minimal, in practice, both methods can be used equally.

Since this difference is minimal, in practice, both methods can be used equally.","PeriodicalId":180624,"journal":{"name":"Serbian Dental Journal","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134466576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Summary Introduction Citation analysis, as one of the best-known bibliometric approaches, is widely used in the evaluation of research output and assessment of research performance and impact. The purpose of this study was to identify the top cited articles published by researchers affiliated to Serbian dental institutions and to analyze their characteristics in order to describe cooperation at individual and institutional, as well as at national and international level. Material and Methods Articles that cited the most 2018 publication in the Web of Science were assessed. The analyzed aspects covered distribution of annual production, annual citations, journals, categories, countries, institutions, authors, research focuses and trends by author keywords and KeyWords Plus. Results The top cited papers were published in 60 journals from 1997 to 2016, with the mean number of 45.08 citations per article. These papers were co-authored by 449 authors, responsible for 726 authorships, affiliated to 149 institutions from 41 countries. Among the overall number of authors, 238 were from Serbia, while 211 were affiliated with international institutions. The most productive institutions were the University of Belgrade and Military Medical Academy from Serbia, whilst the international contributing institutions were primarily from the USA, England, and Italy. Conclusion The present study presented useful insight into the most influential Serbian dental institutions research, revealing the most productive actors and multidisciplinary nature of the research contribution.
