The power of healing and the power of prevention are two concepts that are meaningful to any dental practitioner. Nobio Limited from Israel has introduced a suite of FDA-cleared materials that incorporate antibacterial technology that prevents demineralization at the tooth-restorative interface. Maintaining marginal integrity greatly reduces the chance of secondary decay.

Nobio’s proprietary QASi technology allows for long-term, nonreleasing, nonleaching antibacterial capability via solid macromolecules with a silica core and high concentration of antimicrobial groups covalently bound to the silica core. This technology is in all three Infinix products: Infinix Universal Composite, Infinix Flowable Composite, and Infinix Universal Bond. What is also unique is that this antibacterial technology is effective against a broad spectrum of bacteria and does not impact normal oral flora. It kills the bacteria between the tooth and cavity wall restoration, ultimately minimizing normal mineral loss in the decay process. Infinix Universal Bond is an FDA-cleared bonding agent with an antibacterial, cavity-cleansing effect. Although I generally favor one-bottle, 7th-generation adhesives, this benefit is huge. You can use this material with total-etch, selective-etch, and self-etch, and I have found no post-op sensitivity. Infinix Flowable Composite (low viscosity) is ideally suited for class III and V and as a base/liner. It is highly radiopaque, cures in only 10 seconds, and is currently available in shade A2. I like it for pits and fissures as a sealant. Infinix Universal Composite handles very well and is easy to sculpt. It is available in shades A2 and A3, which fulfills the need for most anterior and posterior restorations. This is a nano-hybrid material that has a depth of cure of 2 mm in 20 seconds, and it polishes well. The Infinix suite of antibacterial products fit the bill in treating most patients but should be considered a must-use in restorative procedures for high-caries-risk patients.
