Evaluating the effect of glove coating on the sheer bond strength of porcelain laminate veneers
Article Abstract:
Contamination from powder lubricants on dentists' latex gloves may significantly weaken the bonds between porcelain laminate veneers and tooth enamel. Researchers simulated the laminating process by bonding etched porcelain to 90 etched tooth enamel specimens and applied mechanical force to measure the strength of the bonds. During bonding, 30 specimens were contaminated by powder-free gloves, 30 were contaminated by powder-coated gloves, and 30 were not contaminated. Compared with the uncontaminated specimens, the average sheer bond strength was almost 50% lower in specimens contaminated by powder-coated gloves. Bond strength was not significantly reduced in specimens contaminated by the powder-free gloves. When the bonds were broken, half of the uncontaminated specimens and one-third of the specimens contaminated by the powder-free gloves had substantial amounts of porcelain adhering to the enamel. Only three powder-contaminated specimens had even a small amount of porcelain adhering to the enamel.

Latex glove reactions found in a dental school
Article Abstract:
Many dental professionals may have an adverse reaction to latex gloves. Latex gloves are routinely used in dental offices to prevent the transmission of infection. A study examined the incidence of latex-associated reactions among 526 students, faculty and staff of a dental school. Fifteen percent of the students, faculty and staff experienced an adverse reaction to latex gloves. Eighty percent of the individuals who experienced an adverse reaction developed dermatitis. Other common adverse reactions included hives, conjunctivitis and rhinitis, or inflammation of the mucous membrane of the nose. Tachycardia, or rapid heartbeat, low blood pressure and respiratory depression occurred in only three individuals. Clinical personnel were more likely to develop an adverse reaction than non-clinical personnel. The risk of an adverse reaction increased with the frequency of glove use.

The dental team and latex hypersensitivity
Article Abstract:
Dentists should do as much as they can to protect their workers who have latex sensitivity. Natural rubber latex (NRL) is found not only in gloves, but also in dental dams, bite blocks and prophylaxis cups. Most sensitivity to NRL occurs as contact dermatitis but a more serious allergic reaction called anaphylaxis can also occur in some people. Products made of synthetic latex can be used and all dental personnel should know the signs of severe NRL allergy.
