Soladey scientific trials
Canadian trialA blind, two-way crossover clinical trial was carried out by the College of Dentistry, University of Saskatchewan, Canada with 80 high school children of both sexes aged 13-16 years. The aim of the study was to compare the plaque removing ability of the Soladey toothbrush with a toothbrush of identical appearance but with an imitation bar made of synthetic resin (control brush) in place of the semiconductor. Both groups were advised to use the brushes according to manufacturer's instructions for a period of 3 weeks using a small amount of a standard toothpaste which was provided.
The results of this study indicate that the Soladey toothbrush had better plaque removing ability on the buccal surfaces1 of all teeth than the control brush without the semiconductor.

Japanese trial
A study was carried out by the Department of Preventative and Community Dentistry, Nippon Dental University at Tokyo and with 60 adult female subjects who were dental hygiene school students. One group (32) used the Soladey and another group (28) used a conventional toothbrush (control). The subjects' oral conditions were examined 1, 2 and 3 weeks later using five standardised tests.
After the 3rd week there was a significant improvement in gingivitis2 and oral cleanliness in the group using the Soladey compared with the control group.

Caries Research
Recent studies have shown that powdered semiconductors irradiated with light possess the ability to decompose organic substances included lactid acid and that is has a bactericidal effect against several species of microorganisms such as Escherichia coli.
