Mouthwashes are used to control and decrease problems such as the accumulation of microorganisms and plaque in patients undergoing orthodontic treatment. Since the success of fixed orthodontic treatment depends on the bond strength of brackets to the enamel, the present study investigated the possible effects of the SensiKIN mouthwash on the shear bond strength of orthodontic brackets on the enamel surface.
The present case-control study was carried out on 40 extracted sound human premolar teeth (20 in the mouthwash group and 20 in the control group). All the tooth samples were immersed in 0.1% thymol solution for seven days, followed by storage in distilled water at 4ºC for<3 months. In the mouthwash group, the SensiKIN mouthwash was applied to the teeth twice every day for one minute each time for one month. The teeth in both groups were retrieved from the storage solutions for orthodontic procedures. Finally, a universal testing machine was used to determine the shear bond strength of orthodontic brackets to the enamel surface. The data were analyzed using SPSS 26.
The results showed no significant difference in the mean shear bond strengths of orthodontic brackets between the SensiKIN mouthwash group (117.8, 36-387 N, around 11.7 Mpa) and the control group (121.6, 40.3-473.3 N, around 12.1 MPa) (=0.914).
Since the SensiKIN mouthwash did not decrease the shear bond strength of orthodontic brackets, it can be used during orthodontic treatment.
漱口水用于控制和减少正畸治疗患者中微生物和牙菌斑积聚等问题。由于固定正畸治疗的成功取决于托槽与牙釉质的粘结强度，本研究调查了SensiKIN漱口水对牙釉质表面正畸托槽剪切粘结强度的可能影响。
本病例对照研究对40颗拔除的健康人前磨牙进行（漱口水组20颗，对照组20颗）。所有牙齿样本均浸泡在0.1%百里酚溶液中7天，然后在4℃蒸馏水中保存<3个月。在漱口水组，每天两次将SensiKIN漱口水应用于牙齿，每次1分钟，共1个月。两组牙齿从储存溶液中取出用于正畸操作。最后，使用万能试验机测定正畸托槽与牙釉质表面的剪切粘结强度。数据使用SPSS 26进行分析。
结果显示，SensiKIN漱口水组（117.8，36 - 387 N，约11.7 Mpa）和对照组（121.6，40.3 - 473.3 N，约12.1 Mpa）正畸托槽的平均剪切粘结强度无显著差异（=0.914）。
由于SensiKIN漱口水不会降低正畸托槽的剪切粘结强度，因此可在正畸治疗期间使用。
