Abstract

This clinical study evaluated the effect of rinsing with essential oil containing antiseptic mouthrinses, with or without 100-ppm fluoride ion, on the plaque metabolic acid production and plaque pH response after a sucrose challenge. This observer-blind, randomized study used a 3-way crossover design. 24 subjects rinsed with 20 mL of (1) essential oil mouthrinse (EO), (2) essential oil mouthrinse plus 100-ppm fluoride ion (EOF), or 3) negative control for 30 seconds, twice daily for 16 days. On day 17, one hour after the last mouthrinse, subjects rinsed with 20 mL of mass fraction 10% sucrose solution for 1 minute. Seven minutes after the sucrose challenge, supragingival plaque was collected from molar and premolar teeth.Plaque pH and metabolic acid ions were analyzed using a micro pH electrode and capillary electrophoresis, respectively. The results showed that dental plaque evaluated after use of EO mouthrinse produced 36% less lactate, 36% less acetate and 44% less propionate than that after use of negative control rinse. The dental plaque also exhibited a pH 0.42 unit higher after EO rinse than after the negative control rinse. These results were not affected by the addition of 100-ppm fluoride to the EO mouthrinse.
