AbstractExtrinsic 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. A weak chelator did not alter the discoloration tendency. Extrinsic discoloration was evaluated both by direct inspection, from color photographs and by using a microphotometric technique. The discoloration tendency was well demonstrated by all three techniques. Evaluation from the color photographs, however, may be preferable in epidemiological surveys while the microphotometric technique may possess certain advantages in detailed experimental discoloration studies.Key Words: Antibacterial agentsstainingpellicle
