Cavities of Teeth Clinical Trial

Official title: Prospective, Randomized, Split-mouth Study Evaluating Clinical Performance of 3M™ Scotchbond™ Universal Plus Adhesive Compared to 3M Scotchbond Universal Adhesive for Posterior Class I & II Restorations With 3M Filtek™ Universal Restorative

Status Active, not recruiting

Clinical Trial Summary

This research study is looking at a new bond-promoting substance (a dental adhesive called 3M™ Scotchbond™ Universal Plus Adhesive) used between the tooth and dental restoration (filling). This study will evaluate whether Scotchbond™ Universal Plus Adhesive (SBU+) is as effective at bonding dental fillings as Scotchbond™ Universal Adhesive (SBU) for preparation of posterior Class I and Class II restorations in adult patients. Participants must have at least two (2) back teeth that need a filling either on the chewing surface alone (Class I) and/or on the chewing surface and between your teeth (Class II). One tooth will be restored using SBU+ and the other tooth will be restored using SBU adhesive, both filled using Filtek™ Universal Restorative as the filling material.

Clinical Trial Description

This is a prospective, randomized, controlled, open-label, assessor-blinded, split-mouth, single-center post-market clinical follow-up study. The study is designed to compare the clinical efficacy of Scotchbond™ Universal Plus Adhesive with Scotchbond™ Universal Adhesive when used in self-etch mode for preparation of posterior Class I and Class II restorations using Filtek™ Universal Restorative material in adult patients. Selected endpoints are based partly on the FDI World Dental Federation criteria. Subjects who meet all inclusion and none of the exclusion criteria and who have provided informed consent will be eligible for enrollment and must be treated within 21 days of screening. Either two pre-molars or two molars from each Subject will be randomized in a 1:1 ratio such that one of the teeth will be randomized to undergo restoration using SBU+ Adhesive (Treatment), and the other tooth will undergo restoration using SBU Adhesive (Control). Both study teeth will be restored using Filtek™ Universal Restorative material as the filling material. Individual subject participation is expected to last 2 years (± 45 days) with scheduled study visits at screening, day of restoration/baseline, and follow-up visits at 6 months (± 14 days), 1 year (± 30 days), and 2 years (± 45 days) after restoration. 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. Unscheduled visits may be initiated by either the Investigator or the Subject. 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. All assessments will be performed by two 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, then the examiners will compare their evaluations and a consensus will be reached for each of the scoring criteria at each visit. A consensus will be reached before the Subject leaves the visit, and the consensus assessments will be entered into the Case Report Form (CRF). ;
