Abstract

To compare the efficacy of different surface treatments (fiber post) with laser activated irrigation (LAI) technique (various root canal solutions) on root canal dentine in terms of push-out bond strength (PBS) in a fiber post. In this study, 200 premolars were assigned into groups according to various irrigation techniques: 2.5% sodium hypochlorite (NaOCl), 17% ethylene diamine tetra acetic acid (EDTA), and 17% EDTA + LAI. In addition, the fiber posts were separated into five groups, (n = 30) according to the surface pretreatment performed: sandblasting, hydrofluoric acid (HF), Erbium, Chromium:Yttrium Scandium-Gallium-Garnet (Er,Cr:YSGG) laser, Neodymium-Doped Yttrium Aluminum Garnet (Nd,YAG) laser and as untreated surface. The posts were cemented using dual-cure resin cement and subjected to a PBS test. Data were analyzed by one way-ANOVA, Tukey, and Tamhane T2 tests. The PBS values were increased in all parts of the tooth in the EDTA and EDTA + LAI treated groups and in groups treated with Er,Cr:YSGG laser fiber posts. In groups in which EDTA and EDTA + LAI were applied, it was observed that dentinal tubules were open according to the distribution and number of dentinal tubule configurations. The improvement of the PBS between fiber post/resin cement/root dentine was observed via the use of fiber post surface treatments with different irrigation techniques.
