Final answer:
The sealant is applied to the tooth and the bonding material is placed on the bracket during the preparation for attaching orthodontic brackets.
Step-by-step explanation:
After preparing the tooth for bonding brackets, the sealant is placed on the tooth, to protect it and provide a suitable surface for the bonding material, and the bonding material is then placed on the bracket, which will be attached to the tooth. This process is crucial in orthodontic procedures, where brackets are bonded to the teeth to support orthodontic devices, such as wires, that apply pressure to reposition the teeth over time.
