Sažetak
The aim was to examine the shear bond strength of self-adhering composite cement to radicular dentin with respect to different irrigation solutions preceding adhesion - sodi- um hypochlorite (HIPO), ethylene-diamine-tetraacetic acid (EDTA), etidronic acid with HIPO (HEDP) and chlorhexidine (CHX). Materials and Methods: In this study, 41 radicular dentin slabs were sectioned from ex- tracted intact third molars, embedded in acrylate, polished and randomly divided into three experimental groups (N=9-12) and one control group (N=8). In each experimental group, dentin samples were treated with a different irrigation protocol for two minutes : 1) HIPO/EDTA/HIPO 2) HEDP 3) HIPO/EDTA/CHX. The control samples were not exposed to any disinfectant solution mentioned and remained stored in distilled wa- ter. After drying the samples, dual-curing self-adhering composite cement (GC G-CEM LinkForce, GC Tokyo, Japan) was applied to the radicular dentin using the corresponding Ultra Tester cutter molds (Ultradent Products, SAS Institute Inc., Cary, NC, USA). The samples were stored at 100% humidity at 37°C for 10 days. The shear bond strength of the self-adhering cement to radicular dentin was determined according to ISO standard 29022 using an Ultra Tester at a constant speed of 1 mm/min until the cement separated from the dentin. The results for the shear bond strength in MPa were analyzed by the ANOVA statistical test and Tukey HSD post hoc test. The level of statistical significance was α=0.05. Results: HIPO/EDTA/HIPO and HIPO/EDTA/CHX groups showed significantly low- er shear bond strength compared to the control group (p<0.05). Dentin irrigation with HEDP did not significantly reduce the shear bond strength of the self-adhering composite cement to radicular dentin (p>0.05).
