[A comparison of light-hardened and UV-polymerizable sealants and composites].
Ultraviolet irradiation has been used for the photopolymerization of composites and sealers. As new initiators were developed, the effectivity of this system was extended into the visible spectral region. Photo-sensitivity probably only limits the processing period slightly, at least under these conditions relevant for the dental practice. One important advantage is the extension of the maximal tempering depth (2 to 3 times, compared to ultraviolet polymerization). The improved penetrability of the dental substance with increasing wave lengths also reduces the risk of portions of the undercuts not being polymerized.
