Summary
Dental impression materials
Area of Science:
- Dental Materials Science
- Surface Chemistry
- Biomaterials Engineering
Background:
- Accurate dental impressions are crucial for clinical success.
- Material properties like flow and wettability significantly impact impression accuracy.
- Understanding wettability during the working time of dental materials is essential.
Purpose of the Study:
- To develop an experimental setup for measuring wettability of dental impression materials.
- To establish an analysis strategy for evaluating wettability during the material's working time.
- To compare the wettability characteristics of polyether and vinyl polysiloxane (VPS) impression materials.
Main Methods:
- Utilized high-resolution drop shape analysis to measure contact angles.
- Investigated thin films of polyether and vinyl polysiloxane (VPS) impression materials.
- Employed a mathematical model for analyzing contact angle evolution and hydrophilicity kinetics.
Main Results:
- Polyether impression materials exhibited consistent initial hydrophilicity throughout their working time.
- Vinyl polysiloxane (VPS) materials demonstrated rapid kinetics towards a more hydrophilic state.
- The developed methods provided detailed insights into the wetting characteristics of setting impression materials.
Conclusions:
- Both high initial hydrophilicity and rapid kinetics enhance material flow and wetting during impression taking.
- Time-resolved wettability studies are valuable for developing new dental impression materials.
- Wettability studies can complement rheological assessments in material development.

01:19Managing Impressions
172
Impression management encompasses individuals' deliberate efforts to shape how others perceive them during social interactions. This behavior is often employed to conform to social norms, secure approval, or pursue specific goals. While it involves selective self-presentation, it is not necessarily deceptive; individuals frequently present authentic aspects of themselves that align with situational demands.Common strategies include:Ingratiation: where individuals use flattery or agreeableness...

Ingratiation refers to deliberate behaviors aimed at increasing one’s attractiveness or likability to a target person, often for strategic interpersonal or social gain. This set of impression management tactics is especially prevalent in hierarchical contexts, where influencing someone with greater power or authority can yield significant benefits. Several distinct ingratiation strategies have been identified, each leveraging psychological cues to foster favor and affiliation.Opinion...

01:14Impression Management Techniques IV: Altercasting
183
Altercasting is a strategic communication technique in which an individual imposes a specific identity or social role onto another person to influence their behavior and shape the interaction. By presuming a role—such as “responsible leader” or “patient person”—altercasting encourages the target to conform to that identity, often aligning their behavior with the expectations associated with the role. The power of this tactic lies in its subtlety; once a role...

First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

Water and other polar molecules are attracted to ions. The electrostatic attraction between an ion and a molecule with a dipole is called an ion-dipole attraction. These attractions play an important role in the dissolution of ionic compounds in water.
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...
