Methods: Forty extracted single rooted human teeth stored in 0.5% saline were used. Periodontal soft tissues were removed followed by crown separation at the CEJ. All the teeth were randomly divided into two groups. Manually Instrumented Group 1 was irrigated with 5.25% NaOCl and 17% EDTA alternately, same as Ultrasonically Instrumented Group 2. The controls for both groups were irrigated with saline solution. Results: Ultrasonic instrumentation and the combined use of two different solutions (5.25% NaOCl and 17% EDTA) yielded better results on smear removal. Conclusions: Irrigation with 17% EDTA followed by 5.25% NaOCl was successful in complete removal of smear layer on cervical and middle thirds of the root canals. Ultrasonic instrumentation was slightly more successful on the apical one third of the root canals.展开更多

Aim: To investigate the utilization of antibiotic drugs at the University Dentistry Clinical Center of Kosovo (UDCCK). Methodology: Retrospective and descriptive study. Patient records were used as a data source collected for a period of 3 months. The total number of registered outpatients in the UDCCK was 1117 patients. The data analysis was performed using the WHO methodology and results were expressed in DDD per 1000 inhabitants per day. Results: The total prescription of antibiotics at UDCCK was 7.18 DDD/ 1000 inhabitants/day. Antibiotics were prescribed for 86 or 7.70% of patients. The most commonly prescribed antibiotic was Amoxicillin with clavulonic acid 3.12 (43.45%) DDD, followed by Metronidazole 2.31 DDD and Amoxicillin 1.25 DDD. Erythromycin and Cefalexin were prescribed evidently less compared to other antibiotics (0.38 and 0.12 DDD/1000 inhabitant/day, respectively). Conclusions: The quantitative analysis showed no rationality of prescription of antibiotics in UDCCK. Generally, the use of antibiotics in both departments of UDCCK is higher compared to other countries. We recommend the implementation of restrictive prescription standards for antibiotics.展开更多
