Patterns and risks of microplastic release during primary oral care in Chinese residents

Researchers studied microplastic release from toothpaste and toothbrushes commonly used in China and found that both products shed significant numbers of plastic particles during normal use. While the levels from any single brushing session were considered low-risk, the cumulative annual release was substantial, reaching hundreds of thousands of particles per person per year from toothbrushes alone. The study highlights oral care products as an overlooked daily source of microplastic entering both people and the environment.

Microplastics in oral healthcare products (OHPs) and their environmental health risks and mitigation measures

Scientists tested common oral healthcare products sold across India, including toothbrushes, toothpaste, mouthwash, and dental floss, and found microplastic contamination in all of them. Toothbrushes released the most particles (30 to 120 per brush), with polyethylene and polyamide being the most common plastic types. This means people are regularly putting microplastics directly into their mouths through everyday dental hygiene products, creating a direct route of exposure.

Detection and Identification of Various Microplastics in Different Orthodontic Adhesives

Researchers found microplastics in four different brands of orthodontic adhesives used by dentists to attach braces. The microplastics were identified as fibers, fragments, and pellets containing various plastic polymers. While the amount is small compared to other plastic pollution sources, this study shows that dental materials can introduce microplastic particles into patients' mouths and eventually into the environment.

Identification of Microplastics as Emerging Contaminant in Branded Milk of Tamil Nadu State, India

Researchers analyzed 16 samples from 13 branded milk products sold in Tamil Nadu, India, and found microplastic particles including polyethylene, polypropylene, and polyacrylamide in all samples. The particles were smaller than 500 micrometers, and contamination levels varied across brands. The findings suggest that plastic packaging may be a source of microplastic contamination in commercially available dairy products.
