A Novel Remineralizing Self-Etch Primer for Orthodontic Bracket Bonding

To evaluate the clinical performance of a newly developed self-etch primer (M-SEP) versus P-SEP in bonding metallic orthodontic brackets to different teeth, verify the potential remineralization effect, and examine the amount of adhesive remnants left on enamel over a period of 6 months.

Objectives:

Primary; Evaluating the clinical effectiveness of enamel etching/priming with M-SEP versus P-SEP in achieving clinically adequate bond strengths throughout the assessment of bracket failure rate over a period of 6 months.

Secondary;

• Examining the potential enamel remineralization effect of both systems via the use of Fe-SEM and Raman spectroscopy.
• Assessing the amount of remnant adhesive left post bracket failure (for both systems) via the use of SEM and digital photography.
• Measuring the total time required for remnant adhesive removal post bracket failure/debonding.
• Evaluating patient perception during bracket failure/debonding and subsequent adhesive removal procedure.

Inclusion criteria

• Full permanent dentition including incisors, canines, premolars, and molars (excepting 3rd molars;
• Teeth with sound, non-carious buccal enamel and no pretreatment with chemical agents such as hydrogen peroxide,
• No previous orthodontic treatment with fixed appliances.

Exclusion criteria

• Participants unable to give informed consent,
• Had craniofacial anomalies,
• Require orthognathic surgery as part of their treatment,
• Had congenital enamel defects.
