The relative plaque removal effect of a prebrushing mouthrinse

Article Abstract:

Use of a commercially available prebrushing mouthrinse (Plax) has been advocated to increase the effectiveness of brushing in removing dental plaque. Some studies have found a beneficial effect from this product while others have not. Fifty-one subjects participated in a study of the value of Plax, using a longer brushing time than other studies and toothpaste instead of water. The subjects used one of three regimens during each of the three test periods: rinse for 30 seconds with the commercial product, then do not brush; rinse for 30 seconds with the product, then brush with toothpaste for 30 seconds; and rinse for 30 seconds with water, then brush with toothpaste for 30 seconds. Plaque was evaluated when the subject arrived after having refrained from brushing for the previous 24 hours, and again after the treatment. The Turesky Index was used to evaluate dental plaque. Results showed a clear reduction in plaque for the two groups that brushed their teeth as compared with the group that did not (0.63 and 0.61 compared with 0.11, where the numbers indicate the magnitude of plaque reduction). But no difference was noted according to whether the commercial rinse or water rinse had been used. Some methodological issues are discussed that could have influenced the outcome, but the conditions of a relatively long toothbrushing time (30 seconds) with toothpaste make the findings of this study more applicable to the real-life situation than previous studies. There appears to be no advantage from using Plax as compared with regular brushing for plaque removal. (Consumer Summary produced by Reliance Medical Information, Inc.)

Assessing the efficacy and safety of an electric interdental cleaning device

Article Abstract:

The Braun Oral-B Interclean dental plaque remover appears to be as effective as flossing. Although flossing is very effective for removing plaque between teeth, many people do not have the manual dexterity to floss effectively. The Oral-B Interclean device is electric and can be operated with one hand. It has a filament that rotates between teeth to remove plaque. Researchers asked 170 men and women to use manual flossing or the Oral-B Interclean device every night for six months. Their teeth were examined at three and six months. The Oral-B Interclean device removed plaque as well as manual flossing.

The effect of chewing sugar-free gum after meals on clinical caries incidence

Article Abstract:

Chewing sugar-free gum after meals may reduce the number of dental cavities in children. Researchers randomly assigned 1,402 schoolchildren in Puerto Rico to chew gum for 20 minutes after each meal or to do nothing. At two and three years, the children who chewed the gum had 8% fewer cavities overall. Children who already had cavities developed 11% fewer cavities overall. The study was funded by the William Wrigley Jr. Co.
