Produced roughness on resin filling by mechanical brushing with complex tooth brushes

Abstract

This work evaluated the superficial rough- ness of Z100 and Compoglass light-cured fillings, produced by brushing with the toothbrushes Oral-B 30, Alcance Reach Control, Kolynos Doctor Flexível and Colgate Total. Each brush group was divided into two sub-grups according to water or water and toothpaste association. The samples were mechanically brushed and the surface was analysed with a perfilometer unit. Compoglass, brushed with toothpaste associated with Oral-B 30 presented the highest numeric average of rou- ghness, followed by Alcance Reach Control and Kolynos Doctor Flexível, that didn’t differ statis- tically, and Colgate Total with the lowest statistic average. Z100 showed no difference among the roughness produced after brushing with toothpas- te and the different types of toothbrushes. The same didn’t happen with Compoglass, which also presented higher superficial roughness value in relation to Z100. Key words: resin filling, toothbrushes, toothpas- te, roughness.
