目的：评价两种酸性软饮料（可口可乐和雪碧）对经树脂渗透处理和未经树脂渗透处理的金属正畸托槽剪切粘结强度的体内影响。此外，釉质表面进行了评估，脱粘后，使用扫描电镜microscopic.Materials和方法：60个非龋上颌前磨牙，计划在30个正畸患者提取，被使用。根据测试的软饮料（可口可乐或雪碧）将患者随机分为两组。各组均应用Icon. DMG，Hamburg，德国）进行。患者被告知在室温下用各自的软饮料漱口5分钟，每天三次，持续3个月。剪切粘结强度用万能试验机测试。剪切试验后，用扫描电镜观察釉质侵蚀情况。统计学分析采用双向方差分析，其次是最小显着性差异test.Results：可口可乐组无树脂浸润表现出最低的抗剪切力。两组树脂应用后的扫描电子显微镜照片显示出显着的改善与结果相比，没有树脂的使用，作为釉质出现更平滑，更少的erosives.Conclusion：预处理与渗透树脂已被证明导致剪切粘结强度显着改善，无论类型的软饮料消耗。
Objectives: To evaluate the in vivo effects of two acidic soft drinks (Coca-Cola and Sprite) on the shear bond strength of metal orthodontic brackets with and without resin infiltration treatment. In addition, the enamel surface was evaluated, after debonding, using a scanning electron microscope.Materials and Methods: Sixty non-carious maxillary premolars, scheduled for extraction in 30 orthodontic patients, were used. Patients were randomly divided into two groups according to the soft drink tested (Coca-Cola or Sprite). In each group, application of resin infiltration (Icon. DMG, Hamburg, Germany) was done on one side only before bonding of brackets. Patients were told to rinse their mouth with their respective soft drink at room temperature for 5 minutes, three times a day for 3 months. Shear bond strength was tested with a universal testing machine. After shearing test, a scanning electron microscope was used to evaluate enamel erosion. Statistical analysis was performed by two-way analysis of variance followed by the least significant difference test.Results: The Coca-Cola group without resin infiltration showed the lowest resistance to shearing forces. Scanning electron micrographs of both groups after resin application showed a significant improvement compared with results without resin use, as the enamel appeared smoother and less erosive.Conclusion: Pretreatment with the infiltrating resin has proved to result in a significant improvement in shear bond strength, regardless of the type of soft drink consumed.
