Life usually gets simpler, but in the case of photocuring dental restorative materials, just the opposite is true. Confusing and contradictory barrages of clinical claims have been made with the ever-growing variety of light-curing sources available today. Often, laboratory research or clinical studies related to these systems are lacking prior to their being introduced to the market, leaving the clinician to become the "testing ground." Manufacturers prefer to market the newest technology available, yet, depending on the type of practice and composite system in use, such "state-of-the-art" devices may offer no advantage. For some clinicians, changing to a "fast cure" composite in combination with a traditional QTH light, instead of purchasing a $4,000 PAC light, may be the only improvement in efficiency needed. However, others may want to spend as little time as possible per procedure and do not mind investing in the newest, yet "unproven" technology. Either way, today's clinician needs to be wary of the many claims made by manufacturers of all light-curing units. It is prudent that the clinician, prior to selecting a device, aggressively ask questions and dig for the truth before "buying into" a particular unit or system philosophy. At stake are the durability of restorations, the satisfaction of patient and the well-earned reputation of the operator.
生活通常会变得更简单，但对于光固化牙科修复材料来说，情况却恰恰相反。如今，随着可用的光固化光源种类不断增加，出现了令人困惑且相互矛盾的大量临床宣称。在这些系统推向市场之前，往往缺乏与之相关的实验室研究或临床研究，这使得临床医生成了“试验场”。制造商倾向于推销现有的最新技术，然而，根据所使用的业务类型和复合树脂系统，这种“最先进”的设备可能并无优势。对于一些临床医生而言，改用“快速固化”复合树脂并搭配传统的石英卤钨灯，而非购买一台价值4000美元的等离子弧光固化灯，可能就是提高效率所需的唯一改进措施。然而，其他临床医生可能希望每个操作尽可能少花时间，并且不介意投资于最新的但“未经证实”的技术。不管怎样，如今的临床医生需要警惕所有光固化设备制造商提出的众多宣称。明智的做法是，临床医生在选择设备之前，积极提问并深入挖掘真相，然后再“接受”某一特定设备或系统理念。这关系到修复体的耐久性、患者的满意度以及操作者来之不易的声誉。
