Resumen
El retratamiento endodóntico con ultrasonidos e hipoclorito de sodio elimina eficazmente los selladores biocerámicos difíciles. Este enfoque adyuvante mejora la limpieza y el modelado para obtener resultados exitosos en la terapia del conducto radicular.
Área de la Ciencia:
- Odontología; Endodoncia; Ciencia de Materiales
Sus antecedentes:
- Los selladores biocerámicos en la terapia de conducto radicular presentan desafíos de recuperación debido a la fuerte adhesión y deposición mineral.
- La eliminación completa de materiales biocerámicos durante el retratamiento endodóntico a menudo es difícil.
- La activación ultrasónica es una técnica adyuvante potencial para mejorar la recuperación de selladores biocerámicos.
Objetivo del estudio:
- Evaluar la eficacia de la activación ultrasónica y la irrigación con hipoclorito de sodio en la eliminación del sellador biocerámico durante el retratamiento endodóntico.
- Demostrar una estrategia clínica para el manejo de la terapia de conducto radicular fallida con obturación biocerámica.
Principales métodos:
- Se analizó un caso de retratamiento endodóntico en un paciente con síntomas persistentes después de la terapia de conducto radicular.
- Se emplearon instrumentos de retratamiento rotatorio, activación ultrasónica e irrigación copiosa con hipoclorito de sodio.
- El procedimiento se centró en la eliminación sustancial de material biocerámico para una preparación completa del conducto.
Principales resultados:
- El uso combinado de instrumentos rotatorios, activación ultrasónica e hipoclorito de sodio facilitó la eliminación significativa del sellador biocerámico.
- Se logró una limpieza y modelado efectivos del sistema de conductos radiculares.
- La estrategia de retratamiento permitió la reobturación exitosa.
Conclusiones:
- La eliminación completa de los selladores biocerámicos sigue siendo un desafío, pero es factible con técnicas ultrasónicas e irrigantes adyuvantes.
- Este caso destaca un enfoque exitoso de retratamiento endodóntico para materiales biocerámicos.
- Las técnicas adyuvantes son clínicamente relevantes para el manejo de fallos endodónticos que involucran selladores biocerámicos.

01:12Retrieval
452
Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

01:45ER Retrieval Pathway
4.9K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

3.8K
Within the human body, a complex and detailed system of trillions of cells works in unison to sustain life. Each cell houses a nucleus, which contains 46 chromosomes divided into 23 pairs. Chromosomes are highly coiled structures made of the genetic material DNA. These chromosomes are essential carriers of genetic information, with half inherited from the mother through her egg and the other half from the father's sperm, combining to create the unique genetic makeup of an individual.

414
The behavior of elastoplastic materials under bending stresses, particularly in structural members with rectangular cross-sections, is crucial for predicting material responses and understanding failure modes. Initially, when a bending moment is applied, the stress distribution across the section follows Hooke's Law and is linear and elastic. This distribution means the stress increases from the neutral axis to the maximum at the outer fibers, up to the elastic limit.
