Roughness comparison of samples of indirect composite and zirconium ceramics

Milena Todorova Georgieva Dimitrova

Abstract

Introduction: The clinical efficiency of indirect composite restorations depends on the treatment of the inner surface of the composite (towards the tooth surface). The dental zirconia - an option in the contemporary dental medicine is practically water insoluble, slightly soluble in hydrochloric acid and nitric acid, but slowly soluble in hydrofluoric acid.

Aim: The aim of this article is to assess the roughness of samples of zirconium ceramics and indirect composite by a device for micro-roughness measurement Mitotoyo SJ-210.

Materials and Methods: Object of the experimental examination are 40 samples of sintered zirconium ceramics and 40 samples of indirect composite, etched with 10% hydrofluoric acid and rugged with diamond burr by high speed turbine. Unit of observation is the roughness on the sample surface.

Results: No statistically significant difference was established between untreated zirconia surface and the treated with 10% HF acid samples on the first and third hour after the treatment (p>0.05). It is reported for higher value of roughness on the sixth hour. The highest values of roughness of the zirconia surface are received after the mechanical treatment with diamond burr (green coded). Contrary to that, the difference between the results received for the composite samples (untreated and treated with 10% HF acid/diamond burr) was confirmed to be statistically reliable (p<0.05).

Conclusion: Significantly more effective and clinically applicable is the treatment of the surface of the zirconia and the composite with diamond burr.
