Is polymethyl methacrylate safe during pregnancy?
The medical field has long believed that polymethyl methacrylate (PMMA) vapor is dangerous to a growing fetus, and therefore, women who are pregnant should avoid exposure to it. Symptoms of vapor exposure include eye irritation, coughing, respiratory tract irritation, and irritation of exposed mucous membranes.
Is PMMA harmful?
High doses of PMA or PMMA are potentially lethal.
Is MMA toxic?

However, MMA inhaled by a pregnant woman can reach the fetus and women who may be pregnant should avoid overexposure to MMA.
Is methyl methacrylate (MMA) safe during pregnancy?
Methyl methacrylate (MMA) is commonly used in the fields of dentistry and orthopaedic surgery. However, there remain concerns for the occupational hazards of MMA, particularly during pregnancy and breastfeeding.
What is methyl methacrylate monomer?
Methyl methacrylate is a reactive resin, and the polymerized form is used as cement in dentistry, orthopaedic surgery and ophthalmology. The monomer form of this agent has relaxation effect on smooth muscle systemically, which might be a result of nitric oxide -mediated response. Methyl methacrylate monomer appears as a clear colorless liquid.
What is the purity of methyl methacrylate?
The purity of commercial methyl methacrylate is typically 99.9% (specification, 99.8% min.); it contains traces of acidity as methacrylic acid (0.003% max.; specification, 0.005% max.) and water (0.03% max.; specification, 0.05% max.).
Is methyl methacrylate toxic to humans?
In humans, methyl methacrylate is rapidly metabolized to methacrylic acid. This compound is a mild skin irritant in humans and has the potential to induce skin sensitization in susceptible individuals.
