Resumen
La limpieza de dentaduras postizas con tabletas efervescentes redujo eficazmente la adhesión de Candida y mejoró la rugosidad superficial de la resina acrílica con el tiempo. El agua electrolizada mostró potencial para la rugosidad superficial pero no para la eliminación de Candida, lo que hace que la limpieza química sea óptima para la higiene bucal a largo plazo.
Área de la Ciencia:
- Ciencia de los Materiales Dentales; Microbiología; Ciencia de Superficies
Sus antecedentes:
- La higiene de las dentaduras postizas es crucial para la salud bucal, ya que la rugosidad superficial de la resina acrílica puede aumentar la adhesión de Candida albicans.; Los efectos a largo plazo de varios métodos de limpieza en las propiedades superficiales de las dentaduras postizas requieren investigación.
Objetivo del estudio:
- Comparar el impacto de diferentes procedimientos de limpieza de dentaduras postizas en la rugosidad superficial y la adhesión de Candida de las resinas acrílicas.; Evaluar la efectividad de los métodos de limpieza química, mecánica y con agua electrolizada.
Principales métodos:
- Se sometieron tres materiales de resina acrílica a cuatro métodos de limpieza (agua destilada, tableta efervescente, cepillado, agua electrolizada) hasta por 90 días.; La rugosidad superficial se midió con un perfilómetro de contacto y la adhesión de Candida se cuantificó mediante unidades formadoras de colonias (UFC/mL).
Principales resultados:
- Los procedimientos de limpieza de dentaduras postizas redujeron significativamente la rugosidad superficial de todas las resinas acrílicas después de 30 y 90 días.; Las tabletas efervescentes a base de peróxido alcalino redujeron significativamente la adhesión de Candida en todos los materiales de resina probados.; El agua electrolizada afectó la rugosidad superficial pero fue menos efectiva contra la adhesión de Candida en comparación con las tabletas efervescentes.
Conclusiones:
- La limpieza química con tabletas de limpieza de dentaduras postizas es el método óptimo para la higiene bucal a largo plazo, controlando eficazmente tanto la rugosidad superficial como la adhesión de Candida.; El agua electrolizada puede ser una alternativa viable para mejorar la rugosidad superficial, pero requiere mejoras para la eliminación de Candida.

01:14Adhesion
44.3K
Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

01:23Factors Affecting Dissolution: Particle Size and Effective Surface Area
1.7K
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are...

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

01:14Cell Adhesion in Plants
3.3K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

02:19Buffer Effectiveness
55.2K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
