The D.T. Light-Post is a translucent, radiopaque, quartz-fiber post system that may blend more naturally with a composite core material, especially with all-ceramic restorations. The post comes in four diameters and features a double-taper design that reportedly provides better adaptation to a prepared canal. Fiber-optic construction purportedly allows light to be transmitted through the post so it can be cemented with light- or dual-cured materials. The System Package comes with twenty posts, four drills, One-Step Plus adhesive, etchant gel, Duo-Link resin cement and Light-Core composite resin core material. Duo-Link is a filled, dual-cured, radio-apparent, composite luting cement available in an auto-mix dual-syringe delivery system. Light-Core is a radiopaque, light-cured, core build-up composite material that provides a 5 mm depth of cure.
The D.T. Light-Post is a translucent, radiopaque, quartz-fiber post system that may blend esthetically with a composite core material, especially under all-ceramic restorations. The competitively-priced system package comes complete with posts, bonding agent, resin cement, and composite core material. The double-taper post comes in four diameters to accommodate a variety of teeth or canal sizes. Evaluators found the working time of the resin cement to be adequate and placement was simplified with the automix delivery system. Laboratory testing found the translucent composite core material was easily light-cured up to 5 mm in depth and that the posts, resin cement and core material were of adequate radiopacity. The light-curable composite core is available in two shades: translucent and blue. The color-coded drills and posts simplified identification, lot numbers and expiration dates were provided on the box, syringes, and bottles, and a Material Safety Data Sheet (MSDS) was included with the kit.
The D.T. Light-Post System requires a multi-step resin-cementation technique, which may result in longer treatment times. According to the manufacturer the fiber-optic construction allows light to be transmitted through the post so it can be cemented with light- or dual-cured materials. Laboratory studies, however, recommend the use of dual-cured systems to assure adequate polymerization. Initial clinical studies of fiber post systems seem promising, but longer-term follow-up is necessary to determine whether having a flexible post allows movement of the core, resulting in increased microleakage under the crown, especially when restoring teeth with minimal remaining tooth structure.
