Abstract Several post surface treatments have been recommended to improve the bond strength of resin cements to glass fiber - reinforced composite resin posts in primary teeth root canals. To evaluate the influence of chemical post surface treatment methods on topography and retention of adhesively luted glass fiber - reinforced composite posts in primary teeth. Fifty endodontically treated primary anterior incisors prepared for glass fiber- reinforced composite posts. The posts were submitted to 5 different surface treatments (n = 10): no treatment, silanization, etching with 37% phosphoric, etching with 10% hydrogen peroxide and etching with 21% sodium ethoxide. The posts{u2019} surfaces were examined using an environmental scanning electron microscope (ESEM) then bonded with self - adhesive resin cement (Relay X) and stored in water at 37{u00B0}C for 24 hours.Post retention was measured with push out test at a crosshead speed of 0.5 mm / min using a universal testing machine. Data were analyzed with 1- way ANOVA and the multiple comparisons using |
