Abstract

Background: Hybrid layer formation should be proportional to cement properties to successfully retain fiberglass posts into root canals. Purpose: To measure of hybrid layer thickness in coronal and apical thirds after using one-step and two-step self-etching cements. Methods: This experimental study used 30 human premolars with root-canal treatments, which were assigned into three groups. Fiberglass posts were cemented with three types of self-etching cements following manufacturers’ instructions. Roots were cut in the coronal and apical thirds and hybrid layer thickness was quantified through scanning electron microscopy. Data ​​were analyzed with Kruskal-Wallis and Mann-Whitney tests (p < 0.05). Results: Average thickness of the hybrid layer was 0.74 μm with Multilink N™ (group 1), 0.24 μm with RelyX Ultimate™ (group 2), and 0.03 μm with RelyX U200™ (group 3) (p = 0.0092). Average thickness in coronal and apical thirds were: 1.29 μm and 0.19 μm for group 1; 0.33 μm and 0.14 μm for group 2; and 0.26 μm and 0.23 μm for group 3, differences that were statistically significant (p = 0.043). Conclusions: The thickness of the hybrid layer formed after suing two-step cements was greater than that of one-step cement, especially in the tooth coronal third.
