Hydrophobic Surfaces for Tooth Tissues
Amphipathic Molecules Create Hydrophobic Dental Surface
A highly hydrophobic dental surface coats teeth tissues (enamel, dentin, and cementum) to prepare them for esthetic dental restorations. The anti-microbial coating, created from amphiphilic molecules, acts as an interface between etched dentin and/or enamel and dental composite and protects dental restorations against degradation from water, acid, and enzymes. In addition, it offers anti-biofilm properties at the tissue/restoration interface and may even bond directly to the composite, thus eliminating the need for bonding agents and reducing the number of steps for the procedure.
Protects Dental Restoration
The interface between a tooth and a restoration often fails, leading to secondary caries, restoration and/or tooth fracture, and, ultimately, restoration replacement. Replacing failed dental restorations occupies up to 70% of a dentist’s time. Current technologies to prevent such failures are time consuming and prone to failure due to mastication, hydrolysis, temperature changes, and bacteria biofilm attacks (including acid and enzymatic production). The highly hydrophobic interface in this technology prevents such failures by offering protection against water-mediated degradation and biofilm growth.
BENEFITS AND FEATURES:
