Objective: The purpose of these laboratory studies was to evaluate three toothbrushes for their ability to remove artificial plaque deposits at interproximal sites and along the gingival margin of simulated anterior and posterior teeth, using horizontal and vertical brushing motions.
Methodology: Three toothbrushes were evaluated: elmex SENSITIVE SOFT; elmex SENSITIVE EXTRA SOFT; and the ADA reference. Twenty-four tests on each toothbrush group were conducted, and results were statistically analyzed using ANOVA and the post hoc Tukey test.
Results: In both the interproximal access efficacy and gingival margin cleaning assays, the elmex SENSITIVE EXTRA SOFT and SENSITIVE SOFT toothbrushes were statistically superior (p < 0.001) to the ADA reference toothbrush.
Conclusion: The elmex SENSITIVE SOFT and EXTRA SOFT toothbrushes are predicted to offer excellent plaque removal efficacy interproximal areas and along the gingival margin of both anterior and posterior teeth.
