8 Clinical Trials for Various Conditions
Polymerization shrinkage remains one of the primary disadvantages of composite resin restorative materials (tooth-colored fillings). To minimize the effects of polymerization shrinkage in the restorative treatment, the 3M ESPE company has developed a composite resin called Filtek Bulk Fill Posterior Restorative. Its decreased polymerization shrinkage and properties allow the material to be inserted in one single increment, expediting treatment. This clinical trial is designed to evaluate the performance of the new bulk fill composite resin in Class II (two-surface posterior) fillings.
Study aim is to test whether nano-composite CAD/CAM milled restorations have a similar performance in clinical service to conventional ceramic CAD/CAM restorations.
The purpose of this study is to determine whether two tooth-colored glass ionomer materials are effective for load-bearing dental fillings.
The purpose of this study is to compare the clinical performance of a new resin based filling material to an established resin-based filling material in posterior teeth at 2 different study centers.
The purpose of this study is to extend our knowledge concerning the clinical performance of two dental filling materials in molars. The study will compare two high-strength glass-ionomer filling materials. The investigators hypothesize that after two years (1) the clinical performance of both filling materials shows a similar survival rate, (2) the ChemFil Rock fillings show similar or higher incidence of fracture than Fuji IX GP fillings.
The purpose of this study is to determine whether a new tooth-colored composite material is effective for load-bearing dental fillings.
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.
The objective of this 2-year split mouth comparative study, a randomized controlled study, is to determine whether the simplified placement procedure of the ultra-rapid polymerizing Tetric PowerFlow/ Tetric PowerFill with a reduced light polymerization time (3 s), yields the same clin-ical results as widely used commercially available dental composites (Tetric EvoCeram Bulk Fill, Tetric EvoFlow Bulk Fill) requiring up to 40 seconds of light polymerization time.
