Objective: This study was performed to investigate the effects of a newly developed 360-degree rotating head-type electric toothbrush on tongue plaque and oral malodor in comparison with traditional manual brushing.

Methods: In total, 60 adult volunteers who received compensation participated in this clinical study and were stratified to use either the experimental 360-degree rotating head electric toothbrush or a 360-degree head manual toothbrush control group. Tongue plaque index and volatile sulfur compound (VSC) measurements were calculated using the B&B checker (mBA-21; Plustech) after tongue cleansing instructions were given to both the groups (baseline). Similar data were further collected at 1 week, 2 weeks, and 4 weeks of using the study toothbrushes, and the values of the experimental and the control groups were compared at each period.

Results: Significantly different plaque index values between the two groups were observed at 1, 2, and 4 weeks; more specifically, lower values were recorded in the experimental group (p<0.05). VSC level was also lower in the experimental group than in the control group (p<0.05).

Conclusion: Use of the 360-degree rotating head-type sonic-care electric toothbrush is recommended over a manual toothbrush because of its effectiveness in mitigating tongue plaque and malodor in dental patients complaining of malodor.
