Esthetics of Dental Composite and Adhesive System

Completed · Not applicable

Conditions studied: Cavities of Teeth

In brief

To compare a newly developed filling composite to a current filling composite system. Two restorations will be placed in each subject, one using system A and one using system B. The first system listed in the randomization pair will be placed on first tooth (#4-#13), and the second system on 2nd tooth (#4-#13). The same three researchers will be responsible for placement of all the restorations.
