Liechtenstein has faced an increasing number of natural hazards over recent decades: debris flows, slides, snow avalanches and floods repeatedly endanger the local infrastructure. Geomorphological field mapping and geoelectrical profiling was used to assess hazards near Malbun, a village potentially endangered by landslides, and especially debris flows. The area is located on the tectonic conta...

Artificially synthesized probiotic from Lactobacillus strain, contained in the tested toothpaste, led to an innovative approach in preventive dentistry. A new concept resulting from this research can be explained due to possible mechanisms of action of probiotic bacteria, according to which equilibrium of hostile bacterial flora is achieved by mechanical elimination of cariogenic bacteria from ...

OBJECTIVES The objective of this study was to determine the nature of evidence used to support the withdrawal of marketing authorisations of drug products for safety reasons throughout the European Union (EU) between 2002 and 2011. SETTING Products withdrawn, either by a medicines agency or a marketing authorisation holder, during the period 2002-2011 were identified by conducting detailed se...

UNLABELLED The purpose of the study was to compare temperature rise during polymerisation of resin based composites (RBCs) with two LED light curing units (LCUs) compared to a halogen control light. METHODS Forty-five extracted molars, patients aging 11-18 years were used. Thermocouples (TCs) were placed in contact with the roof of the pulp chamber using a 'split-tooth' method. Teeth were pla...

AIM To achieve satisfactory aesthetic appearance of ceramic veneers food debris retention and plaque formation, resulting in possible irritation of surrounding tissues, should be avoided. It is, therefore, necessary to decrease the roughness of ceramic surfaces as much as possible. The aim of this study was to evaluate surface roughness of ceramic veneers after polishin15038787 g with four diff...

Recently, new generations of nanoceramic composite resin CAD/CAM blocks, have been introduced to dentistry, which are claimed to have higher flexural strength, fracture, fatigue and wear resistance, and beside natural looking appearances can be polished easily. Therefore, the aim of this study was to compare flexural strength of 2 nanoceramic composite resin CAD/CAM blocks (Lava Ultimate and Vi...
