Clinical Investigation of a New Bulk Fill Composite Resin in the Restoration of Posterior Teeth

Clinical Investigation of a New Bulk Fill Composite Resin in the Restoration of Posterior Teeth

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.

Inclusion Criteria:

• Be 18 years of age and older
• Have a pair of similar cavities or failed dental fillings in vital permanent posterior teeth requiring treatment
• Be capable of giving written informed consent.

Exclusion Criteria:

• Have a self-reported history of any adverse reaction to materials of the types to be evaluated
• Have a medical or dental history that could possibly complicate the provision of the proposed treatment and/or influence the behavior and performance of the treatment in clinical service.
