Toxicity of cyanoacrylate adhesives and their occupational impacts for dental staff.

Cyanoacrylate (CA) and its homologues have a variety of medical, dental and commercial applications as adhesives. The increasing use of CA in dentistry, particularly as an adhesive and sealing glue, has raised concerns regarding its potential toxicity in humans. Reported toxicity of CA is uncommon in the dental workplace, but may manifest as conditions such as urticaria, contact dermatitis and other dermatoses. Dental staff using CA adhesives should avoid direct contact with CA and use appropriate personal protective measures. Maintaining higher levels of humidity, optimizing room ventilation and using special air conditioning filters in the working environment may be useful in minimising the toxicity of volatile CA adhesives.
