University of Tennessee Study

The University of Tennessee Health Science Center College of Dentistry - Bioscience Research Center


The U Tenn. research study intended to evaluate how well using the C-Shape system benefited or hindered progress compared to traditional instruments and manufacturer’s instructions.


After the sealant material was applied with either a traditional series of tools or the C-Shape system, they were put in a thermocycler for 500 rounds. Then, the teeth were sectioned and examined under a scanning electron microscope. Beneath the SEM the marginal adaptation and sealant penetration ability was evaluated.


The study showed consist results with smooth marginal adaption, no ledges and sealant material penetrated the entire fissure.

Clinical Significance:

C-Shape instruments provide exceptional marginal adaptation and sealant penetration, with superior durability in less time.

"Composites are easier to place since there is no pull back"

"Works very well! It makes resins much more efficient to complete"

"I have added it to my composite placement instruments."
