Bio-dental metrology optimum working conditions of polishing agents for better surface quality of dentine tooth surface.II. Effect of some commercial polishing agents

ABSTRACT

The presented paper was carried out to complete the study of part [I] experimentally to determine the effects of specific polishing agents on the enamel or restorative dental materials. Especially the effect on the surface roughness degree and the rate of wear at root planed dentine surfaces. The presented work was based on the assumption that the exposed root surfaces to be tested would be planed during periodental therapy and that the polishing of the exposed dentine surfaces would enhance root surface smoothness. The purpose of the presented paper was the experimental continuation of part [I]; To start investigating the effect of some different polishing agents; [The Detartrine Paste was taken as the first example] on tooth planed root surface for different working conditions; polishing period time, pressure applied to tooth surface, speed of rotation r.p.m. of the Densco rubber polishing cup with the objective to determine the optimum working conditions, to obtain maximum smoothness of the root surfaces, at the same time the amount of wear on the root planed surface was measured. Relations were achieved concluding with the optimum working polishing conditions to get best surface qualities
