Resumen
La erosión dental causa la pérdida de tejido dental. Los parámetros de rugosidad convergentes revelan que las áreas de dentina más rugosas son más reactivas, pero el caseinato de calcio con flúor puede crear superficies resistentes.
Área de la Ciencia:
- Ciencia de Biomateriales
- Investigación Dental
- Química de Superficies
Sus antecedentes:
- La erosión dental, una preocupación creciente debido a las dietas ácidas, provoca la pérdida irreversible de tejido dental.
- Comprender la reactividad de la superficie dental es crucial para desarrollar estrategias de prevención y tratamiento eficaces.
Objetivo del estudio:
- Investigar los conocimientos espacio-temporales de las alteraciones de la superficie dental durante la desmineralización y la remineralización.
- Evaluar el impacto de la fluoración y el caseinato de calcio en la reactividad de la superficie dental.
Principales métodos:
- Se utilizaron parámetros de rugosidad convergentes (Sqconv) medidos mediante interferometría de barrido vertical con luz blanca.
- Se analizaron mapas e histogramas de Sqconv para evaluar los cambios de la superficie durante la desmineralización y la remineralización.
- Se investigaron los efectos del caseinato de calcio y la fluoración en las superficies dentales erosionadas.
Principales resultados:
- La reactividad de la superficie de la dentina es inhomogénea, y las características más rugosas muestran una mayor reactividad a la erosión, desmineralización, remineralización y fluoración.
- La desmineralización y la remineralización son procesos reversibles, que pueden ser inhibidos por la fluoración.
- La aplicación combinada de caseinato de calcio y flúor durante la remineralización crea superficies más resistentes a los ácidos.
Conclusiones:
- Los parámetros de rugosidad convergentes ofrecen información detallada sobre la dinámica de la superficie dental.
- El caseinato de calcio es un agente prometedor para la remineralización, especialmente cuando se combina con flúor para mejorar la resistencia a los ácidos.
- El crecimiento biomimético de hidroxiapatita durante la remineralización es significativamente más lento que la desmineralización, lo que pone de relieve el desafío de restaurar completamente el tejido erosionado.

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

01:16Surface Tension and Surface Energy
3.3K
When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Wood surfacing is a critical finishing process designed to smoothen the wood surface, enhance its dimensional accuracy, and make handling safer. This process compensates for potential shrinkage during the seasoning phase by marginally increasing the wood dimensions before surfacing. It also helps correct some distortions that may occur as the wood dries.
The equipment used in the surfacing process is a plane equipped with rotating blades. This tool efficiently smoothens the wood surface and can...

54.6K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

01:29Area of a Surface of Revolution

Surfaces of revolution are formed when a two-dimensional curve is rotated around an axis, producing a three-dimensional shape. This concept is used in engineering tasks like determining the surface area of a rocket nozzle, where precise calculations are critical for applying uniform heat-resistant coatings. When a curve is revolved about the x-axis, it sweeps out a continuous surface whose area must be calculated accurately to estimate material requirements.Approximating with Conical BandsTo...

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.
