New GuttaFlow filling material has a strong sealing ability and excellent adhesion to dentinal walls and gutta-percha cones. Ketac-Endo showed excellent bond to dentin with a slightly weaker adhesion capacity to the gutta-percha cones in comparison to GuttaFlow.
Introduction. Prognosis of root canal treatment is highly dependent on the quality of endodontic space obturation. The main task of successful root canal treatment is to achieve adequate reparation processes in the apical periodontium. The aim of this study was to evaluate the quality of root canal obturation using the method of gas (argon) penetration through three different endodontic materials. Material and Methods. Thirty recently extracted human single-rooted teeth after root canal instrumentation were divided into three identical groups and obturated with three different endodontic materials: group I - GuttaFlow (RSA, Germany), group II - AH Plus (DeTray, Germany), group III - Acroseal (Septodont, France). The quality of root canal obturation was evaluated using the method of gas permeability. Results. The best results were obtained with GuttaFlow. The average penetration rate of argon was 186.7 seconds. Slightly higher gas porosity had AH Plus, 179.9 seconds, while the highest gas permeability was observed after the application of Acroseal, 178.5 seconds. However, there was no statistically significant difference in gas penetration among these endodontic materials (p>0.05). Conclusion. All three endodontic materials showed gas permeability in a given time interval. The best quality of obturation was achieved with GuttaFlow, while the lowest quality was obtained with Acroseal
The mesiobuccal roots of the first maxillary molars showed multiple canals in 96%, with dominant Vertucci type II and IV of configuration. All canals were curved.
Establishing NHA provided a pattern of national healthcare spending and allowed a comparison of healthcare system in Serbia with the systems of other countries. Analysing a period 2003-2006 revealed a similarity between Serbia and the countries of the European Unity in regard to the level of average financial resources allocation for healthcare expressed as a percentage of GDP, as well as in regard to financiers in the system of healthcare. A high purchasing power disparity, however, in healthcare services was observed between the population of Serbia and other European countries.
Introduction. Collecting data about the structure and function of private health care sector in Serbia and its inclusion in joint health care system is one of the most important issues for making decisions in health care and getting more accurate picture about the possibilities of health care system in Serbia. The aim of this analysis was to compare health institutions, personnel, visits, number of hospital days and morbidity by ICD-10 classification of diseases in public and private health sector in South Backa, Nisava, Toplica and Belgrade district in 2009. Material and Methods. A retrospective comparative analysis was performed using data about private providers of health services obtained from the Institute of Public Health Novi Sad, the Institute of Public Health Nis and the City Institute of Public Health Belgrade. Data about personnel and morbidity in public health sector in Serbia for 2009 was obtained from the Center for Information Technology of the Institute for Public Health of Serbia. Data about public health facilities in South Backa, Nisava, Toplica and Belgrade district in 2009 was obtained from Serbian Chamber of medical institutions. Results. The results showed that health care was provided in Belgrade district in 2009 by total of 1,051 employees in private sector and 31,404 in public sector. We found that public sector had a far wider range of health facilities than private sector, which was mainly due to the number of clinics. In South Backa district private sector had 323 practices, the district of Belgrade 655 and Nisava and Toplica district 173. Seventeen times more visits to households (4,650,423 vs. 267,356) and 111 times greater number of hospital days was provided in public health sector as compared to private health sector (781,083 vs. 7,023) in South Backa district. Conclusion. The conclusion of this analysis was that public health sector has remained the foundation of health care system in Serbia. Private health sector is expanding, but its structure and scope of services is still undervalued as compared to public sector
