The results indicate that biological … With this goal in mind, documents in the series focus on studies and findings considered critical for risk characterization. If inhaled, methyl methacrylate can cause respiratory irritation and labored breathing, and may progress into asthmatic symptoms. The conclusions of the clinical studies are limited, as the retrospective cohort studies [12, 14] are not able to control for MMA exposure specifically among other agents in the dental workplace. However, the typical MMA exposure levels for dental and orthopaedic personnel appear to be substantially less than currently proposed exposure limits. Vapors irritate the eyes and respiratory system. Search strategy according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.

Notably, the breathing zone concentration of MMA during total hip arthroplasties never exceeded 280 ppm in the study by McLaughlin et al. Based on the results of the health effects research presented in this report, and the ambient concentration estimates, it appears that methyl methacrylate as an air pollutant does not pose a threat to the health of the general population. J Bone Joint Surg Am. Since these animal studies [3, 9, 10], there have been a number of investigations examining the levels of exposure of methylmethacrylate in operating room conditions, and there remain concerns for the occupational hazards of MMA, particularly in pregnancy and breastfeeding. At high concentrations, it has CNS and respiratory depressant effects. 2007;64(2):127–33. Exact search criteria used are reported in Additional files 1. This colorless liquid, the methyl ester of methacrylic acid (MAA), is a monomer produced on a large scale for the production of poly (methyl methacrylate) (PMMA). The U.S. Occupational Safety & Health Administration (OSHA) has defined a Permissible Exposure Limit for methyl methacrylate of 100 parts per million (ppm) for an 8-hour time-weighted average, or the average value of an exposure over an 8-hour work shift.

Toxic effects of methyl methacrylate monomer on male genital tissues. Future work may include investigating the attitudes that professionals in dentistry and orthopaedics have towards pregnancy-related effects of MMA. Most important symptoms and effects, both acute and delayed Symptoms/effects: See section 11 for more detailed information on health effects and symptoms. Occup Environ Med. [14] examined 222 cases of miscarriage and 498 controls (births) among female dental workers and a comparison group unexposed to the materials in question. There is no compelling evidence in the existing literature that suggests that exposure to MMA during routine dental and orthopaedic surgery increases risks for pregnancy-related complications. Methyl methacrylate (MMA) is a monomer thatâs also known as methacrylic acid, methyl ester. Methyl methacrylate is not an evil substance; however, when applying and working with acrylic nails the recognized dangers largely overshadow any potential benefits. Methyl methacrylate monomer appears as a clear colorless liquid. This finding contrasts with Dahl and colleagues [12], who did not find any clear adverse effects on fertility when female dental surgeons were compared to high school teachers in Norway. itching.
