Objective: 360 degree round head tooth-brush was designed and produced in order to increase the plaque removal effect on the tooth surface and tongue surface, with the idea of the cleansing the proximal area and dorsum of the tongue effectively, and to reduce the oral malodor. Methods: A clinical test was performed with 60 adult volunteers by dividing with two groups as the experimental and the control. Tooth-brushing instruction as rolling method at buccal and lingual side as well as on the proximal site, and horizontal method on the occlusal surface, by use of 360 degree round head tooth-brush for experimental group, otherwise instructing with the rolling technique for the control group, both in teeth and the tongue. Patient hygiene performance index at the teeth and tongue, and oral malodor were checked by oral examination and B&B Checker, at before and 1, 2 and 4 weeks later, in order to compare the data with before and after as well as the experimental and the control group. Results: It revealed that the PHP index were more decreased in the experimental group than in the control, from the 2 weeks later, both at the teeth surfaces and tongue (p<0.05). Oral malodor was decreased in the experimental group than in the control, from a week later (p<0.05).Conclusion: 360 degree round head toothbrush was effective to control the dental plaque and tongue plaque, as well as for malodor control, under the well trained tooth-brushing technique.
