Evaluation of the Sandblasting on the Rebonding Strength
Evaluation of the Effectiveness of Enamel Surface Treatment Using Sandblasting on the Bond Strength in the Rebonding Process: a Randomized Controlled Trial
Patients at the Orthodontic Department of University of Aleppo Dental School will be selected if they meet the inclusion criteria then fixed orthodontic treatment with 0.018-inch slot MBT appliances will be applied for those patients.
The aim of this study is to compare Two rebonding procedures by applying a split-mouth design. The clinical failure rates of the two rebonding procedures will be evaluated.
研究概览
详细说明
The sample of this study will be chosen after examination of patients referred to the Department of Orthodontics at the University of Aleppo Dental School then subjects who meet the inclusion criteria will be included in this trial.
An information sheet will be given to each possible candidate. Then consent forms will be obtained.
All patients will receive both rebonding procedures by applying split-mouth design. Each patient will be asked to select an opaque sealed envelope from a box with 20 ones. Ten envelopes will Include instructions for applying sandblasting prior to acid-etching on the right upper premolars and acid-etching alone on the left upper premolars. In contrast, the other ten envelopes will include opposite instructions.
A total sample of 80 premolars will be obtained to study the clinical failure rates of the two rebonding procedures.
The 80 premolars will be randomly divided into two groups:
- The first group in which the enamel will be prepared using sandblasting prior to acid-etching.
- The second group in which the enamel will be prepared using acid-etching alone.

参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的：Sandblasting
The enamel surfaces will be subjected to sandblasting prior to acid etching
|
Sandblasting will be applied onto the vestibular surfaces of the teeth before applying the etchant.
|
|
有源比较器：Acid Etching Alone
Acid etching will be applied alone before the rebounding procedures
|
Only acid etching will be applied onto the vestibular surfaces of the teeth before rebonding
