Background Immersion is important for simulation-based education; however, questionnaire-based instruments to measure immersion have some limitations. The aim of the present work is to develop a new instrument to measure immersion among participants in healthcare simulation scenarios. Methods The instrument was developed in four phases: trigger identification, content validity scores, inter-r...

The purpose of this study was to evaluate the effect of degradation of a denture base resin on bond strength to relining resins. Denture base resin specimens were immersed under various conditions to simulate degradation. Tensile bond strength of denture base resin after immersion to relining resins was measured with or without surface grinding. The bond strength of denture base resin without g...

The objective of this study was to measure discolouration using a digital camera on various types of clear orthodontic elastic modules, immersion solutions, and time periods to determine whether the cause of discolouration of these modules was due to simple staining, chemical degradation, or both. Three types of clear orthodontic elastomeric modules were investigated [Plastic ligatures (AO); Po...

BACKGROUND Many strategies are in use with the intention of preventing or minimising delayed onset muscle soreness and fatigue after exercise. Cold-water immersion, in water temperatures of less than 15°C, is currently one of the most popular interventional strategies used after exercise. OBJECTIVES To determine the effects of cold-water immersion in the management of muscle soreness after ex...

Immersive virtual environments (VEs) have often been described as a technology looking for an application. Part of the reluctance from industry to make regular use of immersive VEs stems from the fact that there is no empirical evidence suggesting that immersive applications provide any benefit over non-immersive ones. We present a method in this paper that can be used to statistically support ...

BACKGROUND Water-aided methods for colonoscopy are distinguished by the timing of removal of infused water, predominantly during withdrawal (water immersion) or during insertion (water exchange). OBJECTIVE To discuss the impact of these approaches on colonoscopy pain and adenoma detection rate (ADR). DESIGN Systematic review. SETTING Randomized, controlled trial (RCT) that compared water-...

OBJECTIVES This in vitro study aimed to evaluate the effect of food consumption followed by acidic challenge on enamel erosion. METHODS Seventy-five enamel blocks obtained from bovine teeth were divided randomly into five groups (n=15 per group): GI - erosion with previous immersion in milk; GII - erosion with previous immersion in cheese extract; GIII - erosion with previous immersion in liv...
