Bonding of brackets using a caries-protective adhesive patch
چکیده انگلیسی

ObjectivesThe purpose of this study was to assess the shear bond strength (SBS) of metal brackets when placed with a caries protective adhesive patch.MethodsForty stainless steel brackets (Ormco) were bonded to 40 bovine enamel samples according to the following conditioning/bonding procedures using a resin-based orthodontic luting material (Heliosit Orthodontic, N = 10 per group): (A) 35% phosphoric acid (30 s), rinse and dry; (B) as in A but additional placement of a prototype adhesive patch (Ivoclar Vivadent) using a bonding agent (Heliobond); (C) application of a two-step self-etch adhesive (AdheSE); (D) as in C but additional patch placement. Samples were stored at 37 °C for 24 h. SBS was measured with a universal testing machine with a crosshead speed of 0.5 mm/min and the adhesive remnant index (ARI) was determined under a stereomicroscope (16×).ResultsMean SBS (standard deviation) values were as follows: (A) 16.6 (6.4) MPa; (B) 12.2 (5.8); (C) 12.9 (5.0); and (D) 10.5 (4.7). Analysis of variance followed by Bonferroni correction revealed no statistically significant differences. In 2 (B) and 4 (D) specimens, complete retention of the adhesive patch was observed.ConclusionsAll treatment groups showed adequate bond strength values. The adhesive patch could therefore be applied in combination with orthodontic brackets and seal the enamel adjacent to the bracket.
