The aim of this work is to answer the question as to whether the TiO2 semiconductor integrated into the toothbrush "Denta-Sola" has any effect on the removal of plaque. The clinical study shows that the Silness/Löe and Quigley/Hein plaque indices improved when the "Denta-Solar" was used over a four-week study period, whereas they deteriorated when the toothbrush was used without the semiconductor.
Parents, teachers and pupils altogether seem to be highly interested in the subject of the study. In addition, most of the pupils show good knowledge of the relationship between sugar consumption and the development of dental caries. Nevertheless, in spite of the above mentioned facts, 75% of the pupils prefer sweetened to non-sweetened alternatives. As there are no symptoms of a behavioural change, the hope of nutrition-guidance being an effective means of caries reduction cannot be supported--at least for the present situation in the Federal Republic of Germany.
