Lo que todo dentista debe saber sobre los microplásticos y los materiales dentales
General dentistry
|February 27, 2026
Resumen
Los microplásticos (MPs) de los productos dentales plantean riesgos para la salud a través de la ingestión y la inhalación, afectando potencialmente a múltiples sistemas orgánicos. Se necesita más investigación para gestionar estas partículas de plástico omnipresentes y su impacto ambiental.
Área de la Ciencia:
- Ciencias Ambientales
- Toxicología
- Ciencia de Materiales
Sus antecedentes:
- Los microplásticos (MPs), partículas de plástico de 1 μm a 5 mm, se detectan cada vez más en diversas matrices ambientales y tejidos humanos.
- Las fuentes de MPs son diversas, incluyendo bienes de consumo, procesos industriales y aplicaciones biomédicas, lo que genera preocupación por las implicaciones para la salud humana.
Objetivo del estudio:
- Revisar los riesgos potenciales para la salud asociados con la exposición a microplásticos.
- Identificar las fuentes de microplásticos, con un enfoque específico en los productos dentales.
- Discutir las vías de exposición humana y los efectos sistémicos de los microplásticos.
Principales métodos:
- Revisión de la literatura científica sobre microplásticos.
- Análisis de la generación y presencia de microplásticos en productos dentales.
- Examen de las vías de exposición humana y los datos toxicológicos.
Principales resultados:
- Los productos dentales como pastas de dientes, cepillos de dientes y aparatos de ortodoncia se identifican como fuentes de MPs.
- La exposición humana se produce a través de la ingestión, la inhalación y el contacto dérmico, lo que lleva a la distribución sistémica.
- Los MPs pueden atravesar las barreras biológicas, causando neurotoxicidad, alteración endocrina y posible carcinogenicidad.
Conclusiones:
- Las prácticas de atención dental contribuyen a la contaminación por microplásticos y plantean riesgos potenciales para la salud.
- La investigación continua es crucial para comprender y mitigar los impactos en la salud y el medio ambiente de los microplásticos.
- Las soluciones emergentes como los materiales biodegradables y la mejora de la gestión de residuos requieren una mayor investigación.

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 and...

Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Bioplastics
Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...
Microbial Bioremediation of Plastics
Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...
The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
