STATEMENT OF PROBLEM Resinous die materials have several important advantages including strength, abrasion resistance, and detail reproduction. Despite these advantages, the shrinkage of resinous die materials during polymerization has limited their widespread acceptance. PURPOSE This study determined whether a retarded setting reaction could improve the accuracy of an epoxy resin die system,...

This study determined the influence of coating with either petroleum jelly or light-cured varnish and storage medium on the flexural strength of glass-ionomer cements (GIC). The flexural strength of two glass-ionomer cements (Fuji Equia Fil and Ketac Molar Aplicap) was measured. Specimens (2 × 2 × 25 mm) were prepared in three groups: uncoated, coated with petroleum jelly, or coated with light-...

PURPOSE To determine whether the fracture strengths and failure types differed between metal and zirconia frameworks veneered with pressable or layering ceramics. MATERIALS AND METHODS A phantom molar tooth was prepared and duplicated in 40 cobalt-chromium abutments. Twenty metal (IPS d.SIGN 15, Ivoclar, Vivadent, Schaan, Liechtenstein) and 20 zirconia (IPS e.max ZirCAD, Ivoclar) frameworks w...

BACKGROUND Several surgical techniques have been developed over the past years, and total extraperitoneal and transabdominal preperitoneal inguinal hernia repair are the endoscopic techniques that are most commonly used. AIM To describe and discuss Dulucq's technique and the modifications of using 3-D mesh in total extraperitoneal inguinal hernia repair. METHODS Patients who underwent an el...

AIM Aim of this study was the evaluation of the microhardness of 4 dental sealants polymerised with two different curing units. METHODS Twenty samples (5 x 5x 2 mm) were prepared with 4 different sealants; 10 samples for each group were polymerised with a plasma curing unit (Apollo 95 E DMD) and 10 with a halogen curing light (Heliolux DLX Vivadent ETS, Schaan, Liechtenstein). For each sectio...

The aim of this study was to delimit potential rockfall propagation zones based on simulated 2 m resolution trajectories using Rockyfor3D for block volume scenarios ranging from 0.05–30 m3, with explicit inclusion the barrier effect standing trees, an area approx. 7200 km2 in Switzerland and Liechtenstein. For determination start cells, as well slope surface characteristics, we used terrain mor...

Objective: This study compares different surface conditioning methods applied to various composite surfaces in order investigate the possible effects on composite-ceramic bond strength. It was aimed increase strength between flowable which is frequently used immediate dentin sealing procedure and ceramic surfaces. Material Methods: Eighty eighty conventional discs were prepared with five discs....

Aims Arable habitats (i.e. fields, orchards, vineyards, and their fallows) were created by humans have been essential elements in Central European landscapes for several millennia. In recent decades, these drastically altered changes land use as well agricultural practices and, more recently, climate change. These precipitated substantial vegetation spatial temporal trajectories not yet exhaust...

Background: COVID-19 has impacted the European microstates of Andorra, Liechtenstein, Malta, Monaco, Republic San Marino, and Vatican City. Even though they have similar population sizes, are rarely studied. The goal was to summarize situation (January 2020–July 2021) for these microstates, as well outcome immunization roll-out throughout first 18 months. While researching incidence mortality t...
