dc.description.abstractThe purpose of this study was to determine the effect of different irrigation solutions on the shear bond\ strength of orthodontic brackets bonded to enamel. Thirty extracted human-premolar teeth were selected and stored\ in thymol solution 0.01% weight/volume until the experiment was undertaken. Subsequently all samples were embedded\ in autopolymerizing acrylic resin with the buccal surface exposure. All specimens were divided randomly into\ three groups according to irrigation solutions; filter water, 0.9% sterile normal saline and deionized water. The\ enamel surface of all specimens were etched with 35% phosphoric acid, rinsed with the assigned irrigation solution,\ dried to a chalky white appearance. Then the UniteTM adhesive primer was applied and gentlely dried. Brackets were\ bonded with self cure adhesive paste (3M-Unitekา) and loaded pressure with Dontrixา at 300 N with forces. The\ specimens were undertaken thermocycling for 24 hours with 500 cycles of 5 oC and 55 oC in controlled humidity\ chamber. The specimens were loaded by the universal testing machine at speed 1 mm/min, Load cell 30 KN, Load axis\ 400 N. The failure loads were recorded in Megapascal. The results showed that the median shear bond strengths for\ the groups irrigation with filter water, 0.9% normal saline and deionized water were 12.91 Mpa (percentile 25, 75 =\ 12.03, 14.21) , 14.51 Mpa (percentile 25, 75 = 12.50, 17.18) and 14.51 MPa (percentile 25, 75 = 12.01, 16.53),\ respectively. The data were analyzed using the Kruskal-Wallis test results P= 0.231. The conclusion was no significant\ differences in the shear bond strengh between the three irrigation solutions.en_US
