Diffusion of peroxides through dentine in vitro with and without prior use of a desensitizing varnish.

Different bleaching regimens are used in dentistry possibly penetrating the dentine and affecting the pulp. The aim of the present study was to investigate peroxide diffusion through dentine pre-treated with a desensitizing varnish (Vivasens®) in a standardized in vitro setup during application of different bleaching materials. The penetration was tested using 1.

[Effects of long-term exposure to street traffic exhaust on the development of skin and respiratory tract diseases in children].

The pathogenesis of allergies can be stimulated by adjuvant effects--i.e. air pollutants such as NOx and particles from diesel engines as well as noise--the latter especially during night-time.

Respiratory and dermatological diseases in children with long-term exposure to road traffic immissions.

The pathogenesis of allergies can be stimulated by adjuvant effects--i.e. air pollutants such as NO(2) and particles from diesel exhausts as well as noise--the latter especially during night-time.
