The Core Material That Delivers More

CORE-FLO™ DC Lite provides unmatched versatility for busy practices

Jack D. Griffin, Jr., DMD

Build-up materials are often thought of as strong, dentin-like, dual-cure composites that are designed to replace tooth structure under crowns and fixed partial dentures. CORE-FLO™ DC Lite is much more than that. The versatility of this material, which has the strength and esthetics needed for many applications in dentistry, is exceptional.

As a core build-up material, CORE-FLO DC Lite is at the top of its class. It has high shear bond strength to dentin, enamel, and fiber posts when used with a bonding agent such as Universal Primer™. It is also an ideal dentin replacement material, providing a strong substructure under materials like zirconia and lithium disilicate. After polymerization, it has a real dentin feel when prepping with no surprise "sink in" or soft areas. These properties make it ideal for use as a core material. It is available in two shades, Natural/A1 and Opaque White, to mask metal posts or dark dentin.

The easy handling, strength, and esthetics give the clinician a high level of confidence in a multitude of clinical situations. The flowability gives the material a self-leveling property without being overly runny while providing excellent adaptability to the preparation. Its low viscosity, moderate film thickness, and dual-cure chemistry make CORE-FLO DC Lite an excellent choice for post cementation. The ability to prepare a post space, place a bonding agent, and complete the core at the same time helps maximize office efficiency and minimize inventory.

CORE-FLO DC Lite has been used as a dentin substitute in large direct composite restorations, achieving excellent clinical results with minimal wear, fracture, and patient sensitivity. The dual-cure chemistry allows for bulk placement without the worry of inadequate curing light penetration or voids when placing multiple layers. Often, clinicians opt to selectively etch a tooth, place Universal Primer, cure after air thinning, and place CORE-FLO DC Lite into the preparation. Chemical cure can occur for 2 to 3 minutes prior to light cure to reduce polymerization shrinkage stresses within the restoration. Occasionally, the entire restoration is even left in occlusion with this material. The product's radiopacity makes it easy to see it on the radiograph, and it is easily distinguished from dentin or decay.

All of these qualities make CORE-FLO DC Lite one of the top materials needed for efficient, repeatable, excellent clinical dentistry. It is a "go-to" material for all clinicians, especially those in a very busy clinical setting.
