摘要
目的评估电池电量对功率（毫瓦）、发射光谱（毫瓦/平方厘米/纳米）以及通过电子商务购买的经认证（FDA/ANVISA）和未经认证的低成本光固化装置（LCUs）的光分布（毫瓦/平方厘米）的影响：方法：七台 LCU，三台通过认证：VALO Grand (Ultradent); Radii Xpert (SDI); and LED.B (Woodpecker); and four uncertified：1 Sec、BS 300、LED 固化灯和 VAFU（VRN，AZDENT）。评估 LCU 的方法是，在三个电池充电周期内使用积分球计算每个 20 秒的连续五个曝光周期后的功率（毫瓦）以及初始和最终周期的发射光谱（毫瓦/平方厘米/纳米）。在电池完全放电之前，每进行 50 次曝光循环后，使用光束轮廓分析检查 LCU 顶端的光分布情况。数据通过功率与曝光次数（R2）之间的线性回归进行分析：结果：经过认证的 LCU VALO Grand（R2=0.005）、LED.B（R2=0.02）和 Radii Xpert（R2=0.09）以及未经认证的 LCU VAFU（R2=0.002）在三个电池充电周期内功率没有明显下降。未经认证的 LCU BS 300（R2=0.87）、1 Sec（R2=0.60）和 LED 固化灯（R2=0.83）显示出明显的功率下降，在电池充电周期结束时发射光谱（毫瓦/平方厘米/纳米）下降。随着连续曝光时间的延长，整个水平电池上有源尖端的光分布发生了显著变化：结论：经过认证的 LCU（VALO Grand、Radii Xpert 和 LED.B）和未经认证的 LCU（VAFU）在测试的电池寿命周期内保持了功率、发射光谱和光分布。经认证的低成本 LCU LED.B 显示出不均匀的光线集中在顶端中心。低成本、未经认证的 LCU--BS 300、1 Sec 和 LED 固化灯--在电池寿命周期内功率显著降低，并且在连续曝光时间内不均匀光分布增加。
Effect of Battery Level During Successive Charging Cycles on the Performance of Certified and Low-cost Uncertified Light-curing Units Available on E-commerce.
Objective: To evaluate the influence of battery level on power (mW), emission spectrum (mW/cm2/ nm), and light distribution on the active tip (mW/ cm2) of certified (FDA/ANVISA) and low-cost uncertified light-curing units (LCUs) purchased through e-commerce.
Methods: Seven LCUs, three certified: VALO Grand (Ultradent); Radii Xpert (SDI); and LED.B (Woodpecker); and four uncertified: 1 Sec; BS 300; LED curing light; and VAFU (VRN, AZDENT), were used. The LCUs were evaluated by calculating the power (mW) after each sequential five exposure cycles of 20 seconds and the emission spectrum (mW/cm2/nm) in the initial and final cycles, using an integrating sphere during three battery charging cycles. Beam profiling was used to check the light distribution on the LCU tip after every 50 exposure cycles until the battery fully discharged. Data were analyzed by linear regression between power and the number of exposure times (R2).
Results: The certified LCUs VALO Grand (R2=0.005), LED.B (R2=0.02), and Radii Xpert (R2=0.09) and the uncertified LCU VAFU (R2=0.002) had no significant power reduction during the three battery charging cycles. The uncertified LCUs BS 300 (R2=0.87), 1 Sec (R2=0.60), and LED curing light (R2=0.83) showed significant power reduction, decreasing the emission spectrum (mW/cm2/nm) at the end of the battery charging cycle. The light distribution on the active tip across the level battery was modified significantly with successive exposure times.
Conclusions: The certified LCUs (VALO Grand, Radii Xpert, and LED.B) and uncertified LCU (VAFU), maintained power, emission spectrum, and light distributions during the tested battery life cycles. Low-cost certified LCU LED.B exhibited inhomogeneous light concentrated at the center of the tip. Low-cost uncertified LCUs-BS 300, 1 Sec, and LED curing light-had significant power reductions during the battery cycles and increased inhomogeneous light distribution along the successive exposure times.
期刊介绍：
Operative Dentistry is a refereed, international journal published bi-monthly and distributed to subscribers in over 50 countries. In 2012, we printed 84 articles (672 pages). Papers were submitted by authors from 45 countries, in the categories of Clinical Research, Laboratory Research, Clinical Techniques/Case Presentations and Invited Papers, as well as Editorials and Abstracts.
One of the strong points of our journal is that our current publication time for accepted manuscripts is 4 to 6 months from the date of submission. Clinical Techniques/Case Presentations have a very quick turnaround time, which allows for very rapid publication of clinical based concepts. We also provide color for those papers that would benefit from its use.
The journal does not accept any advertising but you will find postings for faculty positions. Additionally, the journal also does not rent, sell or otherwise allow its subscriber list to be used by any other entity
