Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Materials and Methods: After the removal of the orthodontic appliances, the lingual retainers, which were made of six-stranded stainless steel wire 0.0215 inches in diameter, wiil bent and bond onto the lingual surface of all mandibular anterior teeth. The study will performed using a split-mouth design. In the study group, the SEP will be administired to the teeth's lingual surfaces. In the control group, they will etch using 37% phosphoric etchant liquid gel. After etching, the primer wiil be applied. The adhesive resin was applied and the lingual retainer was fitted. The patients will be re-valuated over 24 months. The first bond failures and the amount of adhesive remaining on the tooth will be recorded as the adhesive remnant index (ARI) scores.
The chi-square test will be used to compare the bond failure rates and ARI scores between the groups. The survival rates of the retainers will be estimated using the Kaplan-Meier test. The significance level will P \< 0.05.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control group
The primer (Transbond XT Primer; 3M Unitek, California) was applied in a thin and uniform coat. Then the adhesive resin (Transbond LR Light Cure Adhesive Paste; 3M Unitek, California) was administered to the lingual surface of the anterior teeth and the lingual retainer was placed in position. The adhesive resin was polymerized from two directions for a total of 20 s using a visible-light curing unit (Hilux 200, Benlioglu Dental Inc., Ankara, Turkey) with an output power of 600 mW/cm2.
Orthodontic retainer bonding
Self-etch primer (Transbond XT Primer; 3M Unitek, California) was administered to the teeth's lingual surfaces.
Study group
In the study group, the SEP (3M Unitek, Monrovia, California) was used according to the manufacturer's instructions, namely it was administered to the lingual surfaces of the teeth and rubbed for 3 s. Then a gentle burst of dry air was delivered to thin the primer. In the control group, the lingual surfaces of the teeth were etched using 37% phosphoric etchant liquid gel (3M Espe, St Paul, Minnesota, USA) for 30 s, followed by rinsing and drying.
