Abstract

Objective: The aim of this study was to compare the light transmission of monowave and polywave-curing devices by a bulk-fill composite containing only camphorquinone as a photoinitiator.

Materials and methods: Three light-curing devices were used to cure bulk-fill composite QuiXfil: one monowave (Translux® Wave) and two polywave (VALO Cordless and Bluephase® PowerCure. The NIST-calibrated spectrometer (MARC Resin Calibrator, BlueLight Analytics Inc.) was used to measure the incident and transmitted light through a 2-mm composite specimen over 20 s. Light transmittance was calculated from the ratio of the amount of transmitted and incident light. For data analysis (ANOVA, α = 0.05), total irradiation of the entire spectrum, irradiation with wavelengths of 360-420 nm for the violet spectrum, and 420-540 nm for the blue spectrum were selected.

Results: Monowave curing unit Translux® Wave had the lowest light transmission (13.78 ± 0.5%), similar to the violet light transmission of polywave devices (12.02 ± 0.94% and 13.81 ± 1.72% for Valo Cordless and Bluephase PowerCure, respectively). Blue light transmittance (32.15-23.70%) was more than twofold higher than for the wavelengths in the violet region of the spectrum (13.81-12.02%) for the two polywave devices. VALO Cordless showed the highest total and blue light transmission (p<0.001). There was no significant difference in the transmission of the violet part of the spectrum between VALO Cordless and Bluephase® PowerCure (p = 0.465).

Conclusion: Within the limitations of this study, we could conclude that polywave curing devices can be used for the polymerization of the bulk-fill composite with camphorquinone as the sole photoinitiator.

单波与多波光固化装置：对无替代光引发剂的复合材料透光率的影响。

研究目的本研究旨在比较单波和多波固化设备在仅含樟脑醌作为光引发剂的填充复合材料上的透光率：使用三种光固化设备固化松散填充复合材料 QuiXfil：一种单波（Translux® Wave）和两种多波（VALO Cordless 和 Bluephase® PowerCure）。使用经过 NIST 校准的光谱仪（MARC 树脂校准器，BlueLight Analytics 公司）测量 20 秒内通过 2 毫米复合材料试样的入射光和透射光。在数据分析中（方差分析，α = 0.05），选择了全光谱照射、波长为 360-420 纳米的紫光谱照射和波长为 420-540 纳米的蓝光谱照射：单波固化设备 Translux® Wave 的透光率最低（13.78 ± 0.5%），与多波设备的紫光透光率相似（Valo Cordless 和 Bluephase PowerCure 的紫光透光率分别为 12.02 ± 0.94% 和 13.81 ± 1.72%）。蓝光透射率（32.15-23.70%）是两种聚波设备紫光波长透射率（13.81-12.02%）的两倍多。VALO Cordless 的总透光率和蓝光透光率最高（p 结论：在本研究的局限性范围内，我们可以得出结论：聚波固化设备可用于以樟脑醌为唯一光引发剂的块状填充复合材料的聚合。
