Clinical Performance of a New Dental Adhesive, 3M™ Scotchbond™ Universal Plus Adhesive, Compared to 3M™ Scotchbond™ Universal Adhesive When Used With 3M™ Filtek™ Universal Restorative to Restore Class V Non-carious Cervical Lesions

This is a prospective, controlled, within-subject, randomized, single-center study that will enroll Subjects scheduled to undergo Class-V NCCL restorations on 2 or 4 teeth treated in pairs according to lesion depth. Enough subjects will be enrolled from a single site located in New Orleans, Louisiana, USA to perform a minimum of 110 restorations (estimated 38 subjects). Each study tooth will be restored using only one type of adhesive, either SBU+ or SBU, and Filtek restorative following manufacturer's directions using the "Total Etch/Etch and Rinse Procedure". Any teeth needing treatment that are not included in the study will be treated by the dentist using the standard of care.

Subjects will be seen during screening (≤21 days before the restoration procedure), on the day of the restoration procedure, 7 days (± 3 days) after restoration (remote visit for subject self-assessment of baseline hypersensitivity), and follow-up visits at 6 months (± 14 days), 1 year (± 30 days), and 2 years (± 45 days) after restorations. Study teeth will be assessed for selected endpoints based partly on FDI (Fédération Dentaire Internationale) World Dental Federation criteria. Subjects may participate in additional unscheduled visits as required during the study if evaluation of any study tooth is required outside of the scheduled study visits. The entire duration of the study is expected to last approximately 3 years, with individual Subject participation expected to last up to 2 years (± 45 days).

To help minimize or avoid bias in the study, randomization of study teeth will occur after teeth preparation but before the initial application of any adhesive. Assessments will be performed by 2 dental examiners that are independent of the dentist that placed the restorations and are blinded to the treatment arms. All examiners will be trained and calibrated for the scoring criteria before any Subject assessment occurs, and examiners will be retrained and recalibrated if any new evaluator is added to the list of assessors. After the second examiner has completed their assessments, the examiners will compare their evaluations and a consensus will be reached for each of the scoring criteria at each visit before the Subject leaves the visit. The consensus assessments will be entered into the Case Report Form (CRF).
