Oxalate solution and collagen-oxalate solution as protective liners for dentine.
The aim of the present study was to evaluate under scanning electron microscopy the ability of different chemically reactive solutions to form a protective layer on dentine. The materials selected were an oxalate solution, a collagen-oxalate solution, a collagen-oxalate solution plus glutaraldehyde and a saline control solution. Small dentine fragments, obtained from extracted human teeth, were treated with the various chemical solution for 60 seconds. All samples were then examined in a Jeol scanning electron microscope. The preliminary observations suggest that dentine may be covered by a mixture of oxalate crystals and collagen producing a homogeneous layer of reactive agents.
