Abstract

Introduction: The physical condition of the tip and the irradiance of LCUs used in dental offices in the United States and Canada was assessed twice.

Methods: The tip irradiance and physical condition of the tip of 1067 LCUs from 544 dental clinics were assessed twice between 2015 and 2021 using the CheckMARC (BlueLight) radiometer. The irradiance values were compared by paired Student's t-test (α = 0.05).

Results: There was a wide range of irradiance values (200 to 3,777 mW/cm²). At the first assessment, only 26% of the LCUs had no visible damage or debris on the LCU tip. When retested up to 36 months later, 70% of the LCUs had their tip damage or debris issues entirely or partially resolved. 2.6% of the LCUs delivered an irradiance below 500 mW/cm² on the first and 1.6% on the second assessments. For the 5 brands that had a sufficient sample size, it was concluded that the irradiance increased when the tip damage or presence of tip debris was resolved.

Conclusions: Initially, most LCUs (74%) had at least one problem related to damage or debris on the LCU tip. The irradiance increased when the tip damage or debris was resolved.

对 2015 至 2021 年间两次测量的 1067 个光固化单元进行评估。

介绍：对美国和加拿大牙科诊所使用的低辐照度装置的尖端物理状况和辐照度进行了两次评估：方法：在 2015 年至 2021 年期间，使用 CheckMARC (BlueLight) 辐照度计对来自 544 家牙科诊所的 1067 个 LCU 的尖端辐照度和尖端物理状况进行了两次评估。辐照度值通过配对学生 t 检验（α = 0.05）进行比较：结果：辐照度值的范围很广（200 至 3,777 mW/cm²）。在首次评估时，只有 26% 的 LCU 的顶端没有明显的损坏或碎片。36 个月后再次测试时，70% 的 LCU 已完全或部分解决了顶端损坏或碎片问题。2.6% 的 LCU 在第一次和第二次评估中的辐照度分别低于 500 mW/cm²和 1.6%。对于样本量足够大的 5 个品牌，结论是当顶端损坏或存在顶端碎片的问题得到解决后，辐照度会增加：最初，大多数 LCU（74%）至少有一个与 LCU 尖端损坏或碎片有关的问题。当顶端损坏或碎片得到解决时，辐照度就会增加。
