Dose-Related Effects of ZnCl₂on Dental Plaque Formation and Plaque Acidogenicity in vivo

Abstract

The plaque-inhibiting capacity of 5-, 10-, 20-, and 100-mM ZnCl₂ solutions was examined in 10 dental hygienist students. Twice daily mouthrinses with a 10-ml solution of 5, 10, and 20 mM ZnCl₂ significantly inhibited plaque formation (p ≤ 0.05), whereas 100 mM ZnCl₂ had only a negligible effect. Mouthrinses with 5 and 100 mM ZnCl₂ were also tested in 6 dental students characterized as being heavy plaque formers. In this group, the antiplaque effect of 5 mMZnΔ¾ was more pronounced, while 100 mM ZnCl₂ also significantly decreased plaque accumulation. The effect of a single mouthrinse with a 10-ml solution of 5 and 100 mMZnCl₂on plaque acidogenicity was also assessed in 5 dental students. 5 mM ZnCl₂ significantly depressed acid production by plaque 30 min after a rinse, while 100 mM ZnCl₂ inhibited acid production significantly for up to 4 h. 100 mM ZnCl₂ was significantly more effective at depressing acid production than 5 mM ZnCl₂ 30 min after a rinse.

The effectiveness of self‐performed mechanical plaque control with triclosan containing dentifrices

“…A general conclusion is that zinc has a moderate inhibitory effect on plaque formation, most notably in individuals who are heavy plaque formers (31). Additive or synergistic effects have been proposed for a combination of zinc salts and antimicrobial agents and/or surfactants (35, 36, 37, 38), indicating different or complementary modes of action.…”
