The hardness of bovine dentine after glutaraldehyde treatment

Bovine dentine specimens were treated with glutaraldehyde 2% for periods of 10, 20 min. and 48 h. The differences in Knoop hardness were measured and evaluated. It can be concluded that treatment of bovine dentine with glutaraldehyde gives first a remarkable softening (+/- 15%); afterward the treated dentine is +/- 15% harder than untreated dentine.
