The aim of this study was the examination of the permeation behaviour of an established dental bonding (Syntac® Classic, Vivadent-Ivoclar, Schaan/Liechtenstein) through different glove materials. Methods: Four different glove materials (latex (n=10), nitrile (n=4), neoprene (n=3) and styrene butadiene (n=1)) were selected. The tip of each middle finger was dissected, turned inside out and pulled over a glass tube. The closable tube was filled with 0.5 mL Syntac® Classic Adhesive and inserted into a glass chamber containing 5.0 mL aqua bidestillata. After elution times between 2 and 720 minutes samples of 0.2 mL were taken under addition of 0.02 mL of a 0.1 M caffeine solution (internal standard). All samples have been analyzed by gas chromatogaphy (Carlo Erba, Rodano/Italy) using an Optima® Delta-3 column (Macherey & Nagel, Düren/Germany) and a Shimadzu® C-R3A for edition of the data. Statistics was calculated by one way ANOVA and Student-Newman-Keuls Multiple-Range-Test (p<.05). Results: Glutaraldehyde (GA) was the only component of Syntac® Classic Adhesive which penetrated the glove membranes. Most gloves showed breakthrough times (BTT) between 2 and 4 hours, 3 latex brands had shorter BTT, neoprene brands resisted longer against GA. Over all, latex gloves without inner coating showed significantly higher permeation values than nitrile, neoprene or styrene butadiene gloves. Only one latex brand, the inner-coated latex glove Biogel® D was impermeable for the whole experimental period of 12 hrs. Conclusions: The permeation of GA might depend on the material as well as on the layer-strength. A prominent inhibiting influence can moreover result from an inner coating. Thus the glove material nitrile, and especially neoprene, styrene butadiene or additional inner coatings are able to increase the protective effect against permeation of aldehydes. | ||
