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.
紫外线照射已用于复合材料和封闭剂的光聚合反应。随着新型引发剂的开发，该系统的有效性扩展到了可见光谱区域。至少在这些与牙科实践相关的条件下，光敏性可能只会稍微限制加工时间。一个重要的优点是最大回火深度有所增加（与紫外线聚合相比增加了2至3倍）。随着波长增加，牙科材料的渗透性提高，这也降低了倒凹部分未聚合的风险。
