The role of rural population in agricultural development in the P inja district
Jovanovi? Slavoljub,ivkovi? Ljiljana
Glasnik Srpskog Geografskog Dru?tva , 2011, DOI: 10.2298/gsgd1101065j
Abstract: Research results presented in this paper refer to changes in the structure of the agricultural population of the P inja District in the period from 1971 to 2002. They point to markedly decrease in the agricultural population, the share of agricultural population in total population, the share of rural population in total population, as well as the share of active agricultural population in total active population. The process of deagrarianization in this area is a constraining factor for the development of agriculture and causes spontaneous abandonment by working-age population who is employing in other sectors. Transfer of agricultural population in non-agricultural activities takes place either by moving into the city centre or by remaining in agricultural households and employing in non-agricultural activities (which causes daily rural-urban migration). The process of depopulation and deruralization caused ageing population to be involved in agriculture in many rural settlements so that the effects of agricultural production have become significantly decreasing. To eliminate the negative effects of the regional development of the P inja District, it is necessary to establish and implement a functional demographic policy and concept of the revitalization of rural area.

Pavlovi? Violeta,ivkoviSlavoljub
Stomatolo?ki Glasnik Srbije , 2008, DOI: 10.2298/sgs0804221p
Abstract: Aim: To evaluate the effect of irrigation techniques, i.e. different types of irrigation needles, on the quality of cleaning of root canal walls using scanning electron microscopy (SEM). Material and Method: The study was conducted on 16 extracted, single-rooted, human teeth. The samples were allocated to two experimental groups depending on the type of the irrigation needle. Conventional needles were used for the irrigation of Group I and laterally perforated ones for Group II. All root canals were instrumented using K files and the Step-back technique. During instrumentation, all samples were irrigated with 2.5 % sodium hypochlorite solution followed by final irrigation with 17 % EDTA for 1 min. After that, all samples were irrigated with 10 ml of distilled water. The roots were, then, sectioned longitudinally and middle one third of each root canal was analyzed using SEM. Quantitative analysis was based on criteria by Hülsmann et al. Results: The obtained results showed that the more efficient removal of debris and the smear layer was accomplished in the group of samples irrigated using laterally perforated needles than conventional needles. The difference between the investigated irrigation techniques were statistically significant (p<0.01). Conclusion: The use of laterally perforated needles for irrigation allows more efficient cleaning of root canal walls, i.e. the removal of debris and the smear layer.

Possibility of usage of a homeopathic remedy heparsulfuris in the therapy of endoperiodontal lesion
Brkani? Tatjana,ivkoviSlavoljub
Stomatolo?ki Glasnik Srbije , 2002, DOI: 10.2298/sgs0202053b
Abstract: The aim of this paper was to, on the basis of everyday clinical practice analize the effect of a homeopathic remedy, as a complementary remedy in endodontic therapy of endoperiodontal lesions and chronic apical periodontitis and to radiologically check its effect on the flow and speed of reparation of damaged periodontal tissues. Endodontic therapy was done according to the usual protocol for the therapy of infectious canals with root canal preparation, medication with calcium hydroxide points and hermetic obturation with AH-26 paste. During endodontic treatment patients were taking homeophatic remedy Hepar sulfuris per os three times daily. The remedy stimulates the natural defences mechanism of the organism. Radiological follow up after three months period showed obvious reductiont of radiologic radiolucency in periapical region.
T-scan II occlusal analysis in restorative dentistry
Lazi? Vojkan,ivkoviSlavoljub
Stomatolo?ki Glasnik Srbije , 2002, DOI: 10.2298/sgs0204110l
Abstract: The comparison of accufilm markings and computerized T-Scan II force plots of restorations and occlusal interferences in intercuspal position of the lower jaw, before and after occlusal adjustment showed a great improvement in force distribution, balance of occlusal forces and evenness of the right and left side. The computer analysis through T-Scan II system help us to clearly understand what those well balanced occlusal contacts and force distribution really mean for the proper restorative occlusal therapy.

Petrovi? Violeta,ivkoviSlavoljub
Stomatolo?ki Glasnik Srbije , 2005, DOI: 10.2298/sgs0504193p
Abstract: The aim of this study was to evaluate efficacy in smear layer removal of 17% EDTA and 10% citric acid, using SEM. Material and method: Twenty human, extracted teeth with a single root canal were examined. Whilst instrumentation with step-back technique and manual K files, root canals were irrigated with 2 ml of 2.5% NaOCl, between each file size. After instrumentatio n, specimens were divided into two groups. The first group was irrigated with a final flush of 17% EDTA, during one minute, and the second group was irrigated with a 10% citric acid. Results: Irrigation with 17% EDTA and 10% citric acid removed smear layer from the root canals walls. There was not statistically significant differences (p>0.05) in cleaning ability between EDTA and citric acid groups.
Chemism of networking and biological functions of different types of phosphate cements
Jokanovi? Vukoman,ivkoviSlavoljub
Stomatolo?ki Glasnik Srbije , 2013, DOI: 10.2298/sgs1301032j
Abstract: This article provides an overview of calcium phosphate systems used in different formulations of cement mixtures. Chemism of reactions that occur in contact of these systems with water medium shows diversity and specificity of each of selected types of mixtures. As it can be clearly seen from reactions that occur between components of cement mixtures, highly active calcium deficient hydroxyapatite is always an end product in all reactions. This makes these systems extremely biocompatible and suitable for use in dentistry from the standpoint of chemical and biological degradability.
Chlorhexidine as a root canal irrigant: Antimicrobial and scanning electron microscopic evaluation
Pavlovi? Violeta,ivkoviSlavoljub
Srpski Arhiv za Celokupno Lekarstvo , 2010, DOI: 10.2298/sarh1010557p
Abstract: Introduction. Selection of irrigant is very important for longterm success of root canal therapy. Objective. This study was undertaken to evaluate the antimicrobial effects of 2% chlorhexidine digluconate solution (CHX) against five selected microorganisms and to evaluate its efficacy in root canal cleaning. Methods. In this study, by agar diffusion test, were evaluated antimicrobial effects of three root canal irrigants: 5.25% NaOCl, 2.5% NaOCl and 2% CHX. The microorganisms tested in this study were Staphylococcus aureus, Streptococcus mutans, Enterococcus faecalis, Escherichia coli and Candida albicans. A scanning electron microscope was used to evaluate root canal cleaning ability of 5.25% NaOCl, 2.5% NaOCl, 2% CHX and 15% EDTA. Twelve extracted single-root human teeth were divided into four groups depending on the irrigant used during instrumentation. Mechanical preparation was performed with Step back technique and K files. Data were analyzed statistically by Student’s t-test. Results 5.25% NaOCl was the most effective against all tested microorganisms. 2.5% NaOCl and 2% CHX showed antimicrobial effects against all tested microorganisms but zones of inhibition were smaller. The best results in root canal walls cleaning were obtained in the group where the irrigant was 15% EDTA (score 2.33). In 5.25% NaOCl, 2.5% NaOCl and 2% CHX groups, there was more smear layer (score 4 and 5). Conclusion. 2% chlorhexidine digluconate showed strong antimicrobial effect on the tested microorganisms, but was not effective in cleaning root canal walls.

Ja?imovi? Jelena,ivkoviSlavoljub
Stomatolo?ki Glasnik Srbije , 2010, DOI: 10.2298/sgs1002076j
Abstract: Introduction. Serbian Dental Journal (SDJ) is a major source of formal communication for dentists in this region. The purpose of this bibliometric study was to examine articles published in SDJ in period 2002-2009, in reference to journal productivity and nature of authorships, citation patterns, most frequently cited scientific journals and the role of self-citations. Material and Methods. Bibliographic data, as well as metadata for all articles were taken from the Serbian national citation index SCIndeks. Bibliometric analysis of source articles included the number and type of article, author characteristics and cited literature. For each citation the following data was recorded: author(s), article title, journal title, monographic title, publication type, publication year and language. Results. In this period 193 articles were published and most of them were original research articles. In this period a total of 314 national and international authors cooperated, responsible for 538 authorships. The mean number of authors per article was 2.8. Most cited items in terms of publication type were journal articles (83.5 %), while the most frequently cited journals were just those most relevant in the field of dentistry. Results also indicate that the age of the cited literature is below the norm for medical literature. Conclusion. Obtained numerical indicators do not differ significantly when compared to other scientific and professional journals. However, it can be concluded that it is necessary to increase journal productivity and self-citation rate, as well as citation of current literature, up to five years old. This analysis allows evaluating patterns of scientific communication among dentists in this region, as well as journal's current management strategies in order to define useful future directions for the inclusion into the international system of scientific information exchange.

Jovanovi?-Medojevi? Milica,ivkoviSlavoljub
Stomatolo?ki Glasnik Srbije , 2005, DOI: 10.2298/sgs0503143j
Abstract: The main prerequisite for a successful treatment of pulp disease in apex periodontium is knowledge of morphological characteristics of root canal system, especially one third of his apex. The aim of this work was to define the exact distance of the main and auxiliary openings from the top of medial and distal roots of the first lower permanent molars. Methods: as a research material it was used a hundred extracted first lower molars of the patients of both gender, divided into three age groups. The analysis of the one third of apex was done with the help of binocular magnifying glass and digital roentgenography analysis half of the samples, which were filed with capillary contrast. Results: The results obtained showed that the longest average distance of the main opening from the top of medial root was 0.84mm, and the shortest was 0.61mm; while for the distal root the longest average distance was 0.89mm, and the shortest was 0.62mm. Maximum distance of the auxiliary openings from the top of medial root in the first group was 3.5mm, and the maximum distance of the auxiliary openings from the top of distal root was 2, 5 mm. The results obtained with digital rentgenography showed that the longest average distance of the main opening from the top of medial root was the one noticed in the second age group (0.91mm) then the one from the first group (0,83), and the shortest one in the third age group (0,71mm); as for the distal root: the longest average distance of the main opening from the top of the root was noticed in the third age group (0,95mm) then in the first (0,90mm) and than shortest in the second age group (0,89mm). Conclusion: The distance of the main and auxiliary openings from the top of medial and distal root of the first lower molar varies in the range from 0 to 3,5mm and it depends on the tooth age. .
