Resumen

El tratamiento de dientes inmaduros infectados requiere inducir una barrera apical. El fibrinógeno rico en plaquetas (PRF) combinado con agregado de trióxido mineral (MTA) muestra promesa para la apexificación, aunque la desinfección puede requerir múltiples visitas.

Área de la Ciencia:

Odontología
Endodoncia Regenerativa
Biomateriales

Sus antecedentes:

El tratamiento de dientes permanentes inmaduros no vitales infectados presenta desafíos debido a la ausencia de constricción apical natural.
La apexificación tradicional con hidróxido de calcio implica largos tiempos de tratamiento y resultados impredecibles.
El agregado de trióxido mineral (MTA) ofrece una alternativa más rápida y predecible para inducir una barrera apical.

Objetivo del estudio:

Presentar un reporte de caso sobre el uso de fibrina rica en plaquetas (PRF) como matriz biológica con MTA para la apexificación.
Evaluar la eficacia de este enfoque combinado en dientes inmaduros necróticos.

Principales métodos:

Reporte de caso que detalla el tratamiento endodóntico de un diente inmaduro necrótico.
Se utilizó agregado de trióxido mineral (MTA) en conjunto con fibrina rica en plaquetas (PRF) para la apexificación.
Se adoptó un enfoque de múltiples visitas debido a la persistencia de exudado, priorizando la desinfección exhaustiva.

Principales resultados:

Se empleó la combinación de MTA y PRF para la apexificación en un diente inmaduro necrótico.
El exudado persistente requirió un protocolo de tratamiento escalonado para una desinfección adecuada.
La obturación final se realizó después de lograr un ambiente desinfectado.

Conclusiones:

La fibrina rica en plaquetas (PRF) puede servir como matriz interna biológica en conjunto con MTA para la apexificación.
Si bien se consideró una visita única inicialmente, lograr una desinfección adecuada es primordial, lo que puede requerir múltiples visitas.
Este enfoque ofrece una alternativa prometedora para el manejo de dientes inmaduros necróticos.

Teeth

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Matrix-Assisted Laser Desorption Ionization (MALDI)

Matrix-assisted laser desorption ionization (MALDI) is a powerful analytical technique used in mass spectrometry. It enables the identification and characterization of various biomolecules, including proteins, peptides, nucleic acids, and carbohydrates. MALDI is an ionization technique, widely employed in biological and medical research, as well as in fields like pharmacology and biochemistry.The analyte of interest, a biomolecule or a mixture of biomolecules, is mixed with a suitable matrix...

The Extracellular Matrix

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Data Reporting and Recording

Data Reporting and Recording

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...
