Summary
Priming tooth dentin significantly reduced water evaporation, while enamel evaporation remained less affected by treatments. This finding is crucial for understanding dental material interactions and surface properties.
Area of Science:
- Dental materials science
- Biomaterials
- Surface chemistry
Background:
- Understanding water evaporation from tooth surfaces is critical for evaluating the performance and durability of dental restorative materials.
- Surface treatments can alter the hydrophilicity and water loss characteristics of enamel and dentin.
Purpose of the Study:
- To quantify changes in water evaporation from enamel and dentin following specific surface treatments.
- To compare the effects of acid etching, EDTA conditioning, and GM priming on water evaporation rates.
Main Methods:
- Water evaporation was measured using a Multi probe adapter MPA5 and Tewameter TM300.
- Enamel surfaces were subjected to acid etching and GM priming.
- Dentin surfaces were treated with EDTA conditioning followed by GM priming.
Main Results:
- Dentin exhibited significantly higher water evaporation than enamel.
- Acid etching did not significantly alter enamel water evaporation.
- GM priming significantly reduced water evaporation from both enamel (by ~16.5%) and dentin (by ~19.7%).
- EDTA conditioning significantly increased water evaporation from dentin (by ~31.4%).
Conclusions:
- Dentin priming effectively reduces water evaporation from the dentin surface.
- Surface treatments have differential effects on water evaporation from enamel and dentin.
- These findings have implications for the clinical application and longevity of dental adhesives and restorative procedures.

01:20Preparation of Samples for Electron Microscopy
To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...
01:57Adaptations that Reduce Water Loss
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
01:21Drying Shrinkage
When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...

01:20Porosity and Absorption of Aggregate
Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the aggregate...
