WaterpikTM SensonicTM Complete Care is up to 3x as Effective as Brushing Alone for Improving Gingival Health and up to 5X as Effective for Removing Plaque in Hard-to-Reach Areas

Lyle, MD, Qaqish JG, Goyal, CR, Schuller R. *Data on file, 2023

Objective

To compare the effectiveness of the WaterpikTM SensonicTM Complete Care to the SensonicTM toothbrush alone and a manual toothbrush alone on the reduction of plaque, bleeding, and gingivitis.

Methodology

One hundred five subjects were randomized into three groups in this 4-week, single-blind, parallel clinical trial. Group 1 used the SensonicTM Complete Care (SCC). Group 2 used the SensonicTM toothbrush (STB), and Group 3 used a manual toothbrush (MTB). The participants could not use any additional interdental products or mouthrinses. SensonicTM Complete Care subjects used the SensonicTM toothbrush for two minutes and the water flosser for one minute. The SensonicTM toothbrush group and manual toothbrush group each used their respective product for two minutes. All were given written and verbal instructions. Bleeding, gingivitis, and plaque were measured at baseline, 1-week, 2-weeks, and 4-weeks. Indices used were bleeding on Marginal Probing (BOMP), Modified Gingival Index (MGI), and the Rustogi Modified Navy Plaque Index (RMNPI).

Results

At 4-weeks, the WaterpikTM SensonicTM Complete Care was superior to the SensonicTM toothbrush and the manual toothbrush at reducing bleeding, gingivitis, and plaque. Compared to brushing alone, for whole mouth and proximal scores, the SensonicTM Complete Care was up to 3X as effective at reducing bleeding and up to 2X as effective at reducing gingivitis. For plaque, SCC was 55% more effective for whole mouth reduction and up to 5X better proximally. SCC was also superior to the STB alone, 74.1% vs 48.3% for BOMP (whole mouth), 18.3% vs 14.4% for MGI (whole mouth), and 18.1% vs 5.9% (whole mouth) for RMNPI. SensonicTM Complete Care users saw improvements in whole mouth gingival health over brushing alone as early as 1 week; up to 2X as effective at BOMP and MGI, and 38% better at RMNPI.

Conclusion

The WaterpikTM SensonicTM Complete Care is superior to both a manual and SensonicTM toothbrush alone for reducing bleeding, gingivitis and plaque.
