Abstract

Objective: This study measured 278 new curing lights (LCUs) to determine if they met the manufacturer's specifications.

Materials and methods: Over a 6-year period, the light output from 278 Bluephase Style LCUs was measured before the LCUs were given to students (41 in 2017, 44 in 2018, 46 in 2019, 48 in 2020, 50 in 2021, and 49 in 2022). The radiant exitance (mW/cm²) from each year was compared using ANOVA and Tukey- Kramer multiple comparisons test with adjustment for the unequal sample sizes (α=0.05). The results were also compared against the manufacturer's stated radiant exitance of 1200 mW/cm².

Results: The 278 LCUs delivered an average (± standard deviation) radiant exitance of 1203 ± 16.7 mW/cm². The lowest radiant exitance was 1149 mW/cm² and the highest was 1257 mW/cm². Although there were statistically significant differences in the LCUs from each year, these values were within the manufacturer's tolerance of values of ± 10%. Approximately 13% of the emitted light was below 420 nm, and 87% was above 420 nm.

Conclusion: These new LCUs were all multiple peak LCUs that emitted an average radiant exitance of 1,203 mW/cm² (range 1149 to 1257 mW/cm². Purchasers of the Style LCU can be confident that their new LCU will meet the manufacturer's specifications.

对六年来购买的 278 台新 Bluephase 型光固化设备进行评估。

目标：本研究测量了 278 个新的固化灯（LCU），以确定它们是否符合制造商的规格要求：在 6 年时间里，在将 LCU 分配给学生之前，对 278 台 Bluephase Style LCU 的光输出进行了测量（2017 年 41 台，2018 年 44 台，2019 年 46 台，2020 年 48 台，2021 年 50 台，2022 年 49 台）。使用方差分析和 Tukey- Kramer 多重比较检验对每年的辐射输出（毫瓦/平方厘米）进行了比较，并对不等的样本量进行了调整（α=0.05）。此外，还将结果与制造商规定的 1200 mW/cm² 辐射输出进行了比较：278 台 LCU 的平均（± 标准偏差）辐射输出为 1203 ± 16.7 mW/cm²。最低辐射输出为 1149 mW/cm²，最高为 1257 mW/cm²。虽然每年的 LCU 在统计上都有显著差异，但这些数值都在制造商规定的 ± 10% 的误差范围内。大约 13% 的发射光低于 420 纳米，87% 的发射光高于 420 纳米：这些新型 LCU 都是多峰值 LCU，平均辐射输出功率为 1,203 mW/cm²（范围为 1149 至 1257 mW/cm²）。Style LCU 的购买者可以放心，他们的新 LCU 将符合制造商的规格要求。
