Plaque reduction over time of an integrated oral hygiene system.

This article compares the efficacy of a prototype integrated system (the IntelliClean System from Sonicare and Crest) in the reduction of supragingival plaque to that of a manual toothbrush and conventional toothpaste. The integrated system was compared to a manual toothbrush with conventional toothpaste in a randomized, single-blinded, parallel, 4-week, controlled clinical trial with 100 subjects randomized to each treatment group. There was a low dropout rate, with 89 subjects in the manual toothbrush group (11% loss to follow-up) and 93 subjects in the integrated system group (7% loss to follow-up) completing the study. The Turesky modification of the Quigley and Hein Plaque Index was used to assess full-mouth plaque scores for each subject. Prebrushing plaque scores were obtained at baseline and at 4 weeks after 14 to 20 hours of plaque accumulation. A survey also was conducted at the conclusion of the study to determine the attitude toward the two oral hygiene systems. The integrated system was found to significantly reduce overall and interproximal prebrushing plaque scores over 4 weeks, both by 8.6%, demonstrating statistically significant superiority in overall plaque reduction (P = .002) and interproximal plaque reduction (P < .001) compared to the manual toothbrush with conventional toothpaste, which showed no significant reduction in either overall plaque or interproximal plaque. This study demonstrates that the IntelliClean System from Sonicare and Crest is superior to a manual toothbrush with conventional toothpaste in reducing overall plaque and interproximal plaque over time.

Stain reduction of an integrated oral hygiene system.

This article discusses research to determine the efficacy of a prototype integrated power toothbrush and toothpaste dispensing system, the IntelliClean System from Sonicare and Crest, in the removal of extrinsic stain. The prototype integrated system and a positive control, the Sonicare Elite with conventional toothpaste, were evaluated in 2 randomized, single-blinded, parallel 4-week controlled clinical trials. There was a low dropout rate, with 28 subjects of the 31 randomized in study 1 completing the study (10% loss to follow-up) and 26 subjects of the 28 randomized in study 2 completing the study (7% loss to follow-up). Lobene stain scores were used to assess the extent and intensity of stain for all teeth meeting the criteria for inclusion in the studies. Lobene stain scores were assessed at baseline and after 4 weeks in both studies. A survey also was conducted at the conclusion of each study to determine user attitude toward the integrated system. The prototype integrated system was found to significantly reduce overall extrinsic stain over time, performing not significantly differently from the positive control. Overall, the prototype integrated system reduced the composite measure of stain that encompasses both the extent and intensity of stain by 60%. This research demonstrates that the IntelliClean System from Sonicare and Crest is highly effective in reducing extrinsic stain.
