Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this cross-over clinical research is to evaluate the cleaning efficacy of toothbrushes tufted with two types of tapered bristles and end rounded bristles in removal of interdental plaque with clinical measurement (Plaque Index) and objective measurement (digitally measured plaque area). This study will demonstrate the influence by a type of processing bristles on removal of interdental plaque and determine an agreement between the different evaluation methods.

This is a randomized evaluator-masked crossover study with 10 subjects. Subjects will be randomly allocated to three test groups. Subjects will use the assigned toothbrush at baseline appointment and two times a day for a week. Plaque Index and plaque area will be assessed before/after one time use at baseline and Day 7. Subjects will be assigned to another toothbrush after one week wash-out period.
