Molecular/Mechanical Imaging of Dentin Bonding Substrate

Investigators: Yong Wang, UMKC-Dentistry (PI)
The project aims at using novel high-resolution analytical techniques for direct in situ detection of the molecular structure and micro-mechanics of the bond formed at the adhesive interface with caries-affected dentin and sclerotic dentin. The work identifies the structure/property characteristics that inhibit the formation of a durable bond at the adhesive interface with these clinically relevant dentin substrates. Results from this work have provided critical, new insight into failure mechanisms at the dentin/adhesive interface; failure that can ultimately lead to premature breakdown of the composite restoration.
