简要总结
The aim of this study is to compare the clinical efficacy of different residual orthodontic adhesive removing methods for rebonding debonded metal attachments.
详细描述
- To evaluate and compare the bond failure rates of rebonded brackets using two methods to remove the adhesive remnant and comparing them with contralateral teeth.
- To evaluate and compare the bond failure rates of rebonded brackets between different quadrants and arches.
- To evaluate and compare the bond failure rates of rebonded molar tubes using two methods to remove the adhesive remnant and comparing them with contralateral teeth.
- To evaluate and compare the bond failure rates of rebonded molar tubes between different quadrants and arches.

盲法说明
The attachments will carry out by main investigator who give each side coded key then the attachments will be rebond by blind specialist. The participants will be blinded to group assignment and interventions (double-blinded trial).

结局指标
主要结局
The number of bonding failures will be compared using the chi-square test.
时间窗: baselines
evaluate and compare the bond failure rates. different quadrants and arches.To evaluate and compare the bond failure rates of rebonded attachments(brackets and molar tubes)using two methods (Tungsten carbide bur and sandblasting)) to remove the adhesive remnant and comparing them with contralateral teeth.
次要结局
- The bonding failure between each quadrant will be compared by one way ANOVA.(bsaelines)
