Each of the chemicals was tested alone and in the presence of a 1 per cent suspension of human erythrocytes in saline solution.

Evaluation of extrinsic tooth discoloration

Acta Odontologica Scandinavica, 1979
Extrinsic brown tooth discolorations are frequently detected in connection with antibacterial agents used for chemical plaque control. The present investigation confirmed the staining ability of an antibacterial quarternary ammonium salt, benzethoniumchloride, used as a 2% additive to a dentifrice.
