Clinical studies show that titanium exposed to a light source has an excellent bacterical capacity against Streptococcus mutans., a micro-organism found in the mouth that is particularly related to dental caries.

(Onada et al. photocatalytic bactericidal effect of powdered TiO2 on Streptococcus mutans bateria., Denki Kagaku, 56, 1108-1109, 1988).

In Japan a clinical report on titanium toothbrushes found that dental plaque removal was significant during the early phase of plaque formation and concluded that the brush was effective in the control of plaque.

(Kusonoki et al. A study on the effect of the solar energy toothbrush on the control of dental plaque. J Osaka Odont. Soc., 49; 550-559, 1986).

Another Japanese study concluded that improvements in gingivitis and oral hygiene can be expected by using a toothbrush equipped with a titanium semiconductor.

(Niwa et al. Clinical study on the control of dental plaque using a photo energy conversion toothbrush equipped with a TiO2 semiconductor. Shigaku Vol. 77 No. 2 August 1989).

A clinical study conducted at a Canadian College of Dentistry indicated that removal of plaque - from buccal surfaces especially – was more apparent using the ionic brush than it was using the control brush without semiconductor.

(Hoover et al. Clinical evaluation of a light energy conversion toothbrush. J. Clin. Periodontol. 19: 434-436 1992).
