[Quantitative profilometric surface analyses to verify the accuracy of reproduction of elastic impression material].

The optical fine scanner RM 600 Laser Stylus (Rodenstock) allows in combination with the perthometer S 8P (mechanical scanner, Feinprüf/Perthen) a direct quantitative analysis of elastic impression materials. We verified with this apparatus the accuracy of surface reproduction of thirty-three various impression materials. The mean roughness values (Rz) of the originals and the reproductions showed no significant differences. This result suggests that all materials used have a high surface reproduction and they can be used unrestrictly.

[Reproducibility of surface roughness in vivo using elastomers, compounds and the replica technique].

A direct profilometric evaluation of impression materials, particularly elastic materials, has not been possible up to now. The optical fine scanner RM 600 Laser Stylus (Rodenstock) allows touch-free scanning of surfaces, thus providing a direct quantitative assessment of impressions made with elastic materials. To determine the suitability of various impression materials and methods for direct profilometric analyses, the accuracy of reproduction was verified by comparing the surface structures of elastomer and compound impressions as well as replicas with the original. With two exceptions in the replicas, the mean roughness values (Rz) obtained showed no significant differences. This result suggests that the materials used are suitable for direct profilometric evaluation.

[Preventive dentistry--actually more than 100 years old].

The purpose of this study was to show that an intensified prevention in dentistry is not new to the 20th Century, but rather that man for more than 100 years considered the positive influence of prophylaxis on oral health to be extremely important. Three publications from Süersen (1867), Detzner (1830) and Jantzen (1865) document impressively that nothing has changed today with regard to the actuality of the questions and problems they raised. As one reviews these studies, one is astonished what profound knowledge all three authors already had regarding the etiology, origin, and consequences of caries and gingival disease.
