The condom vs the dental anesthetic cartridge plunger
Unlike condoms which are made from latex, all dental local anesthetic cartridge plungers are manufactured from dry natural rubber, vulcanized at extremely high teperatures using triple valence bonding. The result is that there is no leaching of latex into the local anesthetic solution. Such impurities would be detected if they are present, through normal routine manufacturing checks. To date, there has never been a latex related allergic reaction reported to the FDA, directly associated with dental cartridge plungers. Latex sensitivity in a dental office is largely attributed to products manufactured using the wet rubber process. Ref. West Pharmaceutical Services. Comment to localanesthetics@yahoo.ca Author: M.Sc.
