Evaluation of Infiltrant Application in the Course of Root Cementum Caries with Different Methods of Surface Preparation—An In Vitro Study

The aim of this study is to evaluate the depth penetration an experimental preparation with characteristics a dental infiltrant into decalcified root cementum tissue and observation subjected single repeated twice hydrochloric acid etching process. material consisted 20 human teeth (the group—12 demineralised teeth, control group—8 teeth). A commercially available Icon were used for addition 2% YF3 (yttrium trifluoride) added as indicator facilitate microscopic observation. Each tooth was divided two zones, blue (Icon) red (experimental preparation). subgroups—in first subgroup, applied once, in second subgroup twice, at end infiltrated preparation. longitudinal section morphology chemical composition performed use Hitachi S-3400N scanning electron microscope. Microscopic observations show that tracer most cases agglomerates remains form conglomerates on surface cementum. Single particles are visible, penetrating through tissues dentine structure. degree infiltration resin (depth tissues) visible approx. 80–120 μm. In test group process, good both resins noticeable, however, excessive erosion evident several specimens—indicating damage occurred result processes, each deposit.
