Methacrylate perspective in current dental practice

Abstract

Objective: To provide a current perspective concerning dental personnel sensitivity to methacrylate materials. Overview: Methacrylate related sensitivity and allergies are currently beyond traditional thoughts concerning denture base resins and methyl methacrylate provisional materials. Methacrylates are now ubiquitous in current dental practice and dental personnel should be aware that dental adhesives contain potent sensitizers that may also cross-sensitize individuals to other methacrylates not experienced. The growing sensitivity to 2-hydroxyethyl methacrylate (HEMA) has been described to be epidemic in nature due to the artificial nail industry with dental patients and dental personnel may be more susceptible to dental methacrylate sensitization. While contact dermatitis remains the most prevalent methacrylate-related clinical presentation, respiratory complications and asthma are increasing associated with methacrylate exposure. While additional personal protective equipment (PPE) is thought to be first protective choice, the National Institute for Occupational Safety and Health (NIOSH) considers PPE overall largely ineffective and should be considered only as a last resort. Conclusion: Dental personnel need to be more aware of methacrylate sources and use workplace control measures to limit methacrylate exposures to both dental personnel and patients. Clinical Significance: Sensitivity to methacrylate materials is a growing dental workplace major concern and dental personnel should be aware of both the methacrylate content of current materials and the products that contain ingredients with the most sensitization potential.

Allergic contact dermatitis caused by 2‐hydroxyethyl methacrylate and ethyl cyanoacrylate contained in cosmetic glues among hairdressers and beauticians who perform nail treatments and eyelash extension as well as hair extension applications: A systematic review

“…Such topical information (in any medial format) could be prepared under health pedagogical considerations and might be then presented within the framework of health education programs. This might also apply to other occupational fields for which relevant acrylate exposure has been evidenced in previous studies, such as dental personnel 68‐73 . The German Social Accident Insurance (DGUV) has recognized the problem for dental personnel and initially launched information brochures about acrylate allergy and its prevention.…”

[68][69][70][71][72][73] The German Social Accident Insurance (DGUV) has recognized the problem for dental personnel and initially launched information brochures about acrylate allergy and its prevention. These existing informational materials might serve as a point of entry for developing potential awareness campaigns and future training measures tailored to the needs of workers in occupational groups exposed to acrylates.…”

Occupational hand dermatitis secondary to methacrylates—The ‘manual tray’ sign

“…Methacrylates are used as dental bonding agents and adhesives. A review of methacrylate‐associated ACD found a trend of increasing prevalence among dental professionals with 10% prevalence reported in 2004 and 20%–32%, in 2011 and 2013 1 . Furthermore, allergic cross‐reaction to one acrylic monomer, particularly HEMA, can lead to development of allergy to other monomers 2 …”

In Vitro Analysis of the Mechanical Properties of Hypoallergenic Denture Base Resins

“…PMMA denture base resins can trigger allergic contact dermatitis, such as type IV hypersensitivity or delayed reactions, in patients during prosthodontic procedures [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. The polymerization of methyl methacrylate (MMA) includes the addition of stabilizers such as hydroquinone and initiators such as dibenzoyl peroxide (BPO).…”
