Etching Gels
Journal Title: Saudi Journal of Medical and Pharmaceutical Sciences - Year 2018, Vol 4, Issue 12
Abstract
Aim of this work was to compare properties of two etching gels produce by Kerr Orange and Spofa Dental. Etching gel are water solution of phosphoric acid using in total etch techniques. They are applicable on enamel surface for 30 seconds to make partially dissolving of hydroxyapatite crystals and increase mechanical adhesion between bonding agents and tooth structure. Materials and methods two commercial phosphoric acid gels (Kerr and Spofa Dental) were tested in consistency, thixotropic properties, water disintegration, force necessary for extrusion material from syringe, fil thickness. Results: Kerr materials has higher consistency, is less thixotropic compare to Spofa product, has longer time to dissolve (18 min), lower force necessary to extrusion 5 N and film thickness 4 microns. Conclusion: On the market exist etching gel based on different gelling agent organic gums or fumed silicas. Some clinician prefer material with higher viscosity for some application, other groups of practicing doctors are using less viscous materials.
