Assessment of Subject’s Preference for a Newly Designed Extremely Soft Toothbrush

Objectives: Objective: The aim of the clinical perception study was to investigate the subject's preference for a newly designed Cushion Clean Next Generation Soft-bristle Toothbrush compared to the subject's current toothbrushes (soft, or medium or hard bristle) in an in-use two-week study.
Methods: Methods: Following consent and examinations of initial gingivitis score and self-reported sensitive gums and/or teeth, qualified subjects were instructed to brush twice daily with the type of bristle that was similar to their current toothbrush for 7 days. The subjects returned after 7 days and filled out a questionnaire based on their experience. The subjects were then provided with the Cushion Clean Next Generation Soft-bristle (CCNGS) Toothbrush to use for 7 days. Then the subjects returned after 7 days of usage and filled out the questionnaire based on their experience.
Results: Results: 300 subjects entered the study, 294 subjects complied with the protocol and completed the clinical study. The subjects were asked 6 questions about their current toothbrush, the scores ranged from 2.56 to 3.02 on a 5-point Hedonic scale (1=Not Satisfied, 2=Slightly Satisfied, 3=Moderately Satisfied, 4=Very Satisfied, 5=Extremely Satisfied). The subjects were asked the same 6 questions about their opinions on the CCNGS Toothbrush and the scores ranged from 4.00 to 4.21. The CCNGS Toothbrush showed statistically significant better user satisfaction than their current toothbrushes. Additionally, the subjects were asked 9 questions after the study was completed. Compared to the current toothbrushes, the CCNGS Toothbrush showed scores from 85% to 100% on a dichotomous scale (1=yes, 0=no), having more satisfying results than their current toothbrushes.
Conclusions: Conclusion: The results supported the conclusion that the new Cushion Clean Next Generation Soft-bristle Toothbrush provided a significantly better user experience compared to their current toothbrush (soft, or medium, or hard bristle) after one week of product use.
