DENTACO offers titanium dioxide free scan sprays for the dentist, the laboratory and the industry

DENTACO has been producing matting- resp. scanning-sprays containing titanium dioxide (TiO2) for about 20 years – because of the good optical properties of this material, such as light refraction, reflection, scattering and absorption. However, for over 10 years there is a scientific discussion about the risks of TiO2, recently with increasing intensity. Since 2017, this substance has been classified by the ECHA (European Chemicals Agency) as "possibly carcinogenic". Latest the debate has reached the consumer through various newspaper articles and television reports. In fact this warning actually only applies to inhaling titanium dioxide particles. In other products such as wall paints, toothpastes, plastics etc., the substance is contained in a bound form and is therefore generally considered harmless. However, the latest state of discussion is that in the EU the titanium dioxide shall carry a warning sign that it is carcinogenic if inhaled. France will prohibit titanium dioxide in food from 2020 on. Even though we still consider a scanning spray containing titanium dioxide to be harmless due to the small amount and the rare use of such sprays (especially also because we never used any TiO2 nanoparticles), we cannot and do not want to participate in this debate.


Therefore, at the end of 2017 we started trying to find replacement particles for the TiO2 in both intraoral and extraoral use. Today, all our scan sprays are available without titanium dioxide. Even without this substance, our sprays ensure perfect and fast 3-D images - with all 3D camera systems. Another advantage over TiO2: These particles can also be easily removed from softer surfaces such as fabric without special aids.
