BACKGROUND
To endure the orthodontic forces used throughout treatment, the bond strength of bonded orthodontic brackets must be enough with assessment of shear bond strength when bonding orthodontic brackets with various adhesives.
MATERIALS AND METHODS
Overall, forty extracted premolars due to orthodontic treatment were included. They were split into four equal cohorts with various primers. With both adhesives, shear bond strength had been assessed with and without salivary contamination. SPSS software was used to assess the outcomes. Consideration was given to statistical significance of value of less than 0.05.
RESULTS
Several groups' average bond strengths in MPa were assessed in both dry and contaminated saliva conditions. When it was dry, Transbond Plus demonstrated greater shear bond strength.
CONCLUSION
Hydrophilic Transbond Plus resin outperformed hydrophobic Transbond XT resin in terms of shear bond strength under both situations.
背景
为了承受整个治疗过程中使用的正畸力，在用各种粘合剂粘结正畸托槽时，粘结正畸托槽的粘结强度必须足够，并评估其剪切粘结强度。
材料与方法
总共纳入了40颗因正畸治疗而拔除的前磨牙。它们被分成四组，每组使用不同的底漆。对于两种粘合剂，均在有和没有唾液污染的情况下评估了剪切粘结强度。使用SPSS软件评估结果。考虑到P值小于0.05的统计学显著性。
结果
在干燥和受污染的唾液条件下，评估了几组以MPa为单位的平均粘结强度。在干燥条件下，Transbond Plus表现出更大的剪切粘结强度。
结论
在两种情况下，亲水性的Transbond Plus树脂在剪切粘结强度方面均优于疏水性的Transbond XT树脂。
