Surface changes on dental materials. II. The influence of two different dentifrices on surface roughness measured by laser reflexion and profilometer techniques.
Abstract
Surface changes on eight different dental materials were investigated, using laser reflexion technique and a profilometer. The tested materials were: Acrylic veneers Isosit, Isosit N, K+B+, Multiplus and K+Bpaste Gold Sjödings C Titanium pure non-rolled titanium Ceram a potential ceramic direct filling material The materials were subjected to brushing in a brushing machine, with a toothpaste-water slurry. Two different toothpastes were used separately; Clinomyn and Colgate. The new ceramic material showed no measurable wear by the brushing. All the other materials were affected to some extent. On titanium increasing values of light intensity were obtained thus indicating a smoother surface. Among the veneer materials K+Bpaste was the most wear resistant.
