Scotchbond Universal Plus Compared to Scotchbond Universal for Posterior Class I & II Restorations With Filtek Universal

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 is a randomized, split-mouth study designed to 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.
