Microplastics in the Operatory May Pose a Threat to Patient and Provider Health
A new study reveals dental procedures may contribute to microplastic (MP) contamination in the clinic environment and potentially in patients. From denture soaking to resin grinding, the release of MPs and their toxic effects are raising red flags for oral health professionals.
A recent study has uncovered compelling evidence that common dental procedures may expose patients and clinicians to harmful microplastics (MPs), raising urgent questions about infection control, environmental health, and patient safety in the operatory.
The research offers a comprehensive look at how MPs are generated and distributed during everyday dental activities. Investigators analyzed MP presence in several clinical scenarios, including denture soaking, simulated resin grinding, and environmental sampling of the dental workspace. These procedures released measurable quantities of MPs into the surrounding environment.
But the study didn’t stop at detection. Researchers also conducted cell-based experiments to assess the toxicological effects of these particles. Results revealed that MPs can induce inflammatory responses in oral cells, offering early evidence of a biological pathway that may link exposure to oral and systemic health consequences.
Of particular concern is the release of MPs during resin grinding, a routine process in crown, bridge, and denture adjustments. The high-speed instrumentation not only produces respirable dust but also creates airborne microplastics that may be inhaled or deposited on soft tissues. The study highlights the ease with which these particles can become embedded in clinical environments, potentially contaminating instruments, surfaces, and even dental water lines.
The authors suggest that these findings warrant immediate attention from dental professionals. In addition to the potential harm to oral tissues, the persistence and bioaccumulation of MPs raise concerns about chronic exposure among dental personnel. While the long-term effects are not yet fully understood, early data indicate that MPs may contribute to oxidative stress and inflammatory pathways in the oral cavity.
For now, clinicians can take proactive steps to mitigate risk. Enhancing high-volume suction during aerosol-generating procedures, ensuring proper ventilation, and employing water filtration systems can help reduce airborne and waterborne MP contamination. The study also underscores the need for new guidelines on managing plastic-based materials and improving PPE to guard against microscopic pollutants. Click here to read more.
