Abstract

OBJECTIVE

To evaluate the effects of polymerization conducted by using LED lamps of different wavelengths (polywave and monowave) on the compressive strengths of nanohybrid composite resins Filtek™ Bulk Fill - 3M and 3M™ Filtek™ Z350 XT.

MATERIALS AND METHODS

The study was prospective, experimental , and comparative. The sample consisted of nanohybrid composite resins. The sample size (n) was 100 specimens, divided into 10 groups. CRIS (Checklist for Reporting In-vitro Studies) Guidelines were used for writing this article.

RESULTS

There were statistically significant differences between all groups with < 0.001. Group 2 (nanohybrid composite resin blocks 3M™ Filtek™ Z350 XT with Monowave LED lamps) showed the highest compressive strength of 238.36±34.69N; CI (213.55-263.18) N. This was followed by Group 4 (nanohybrid composite resin blocks 3M™ Filtek™ Z350 XT with Poliwave LED lamps, High Power) and Group 6 (nanohybrid composite resin blocks 3M™ Filtek™ Z350 XT with Poliwave LED lamps, Soft Star), with compressive strengths of 222.33 ± 53.09N, and 209.21 ± 22.52N, respectively.

CONCLUSIONS

Significant differences were found between the compressive strengths of 3M™ Filtek™ Z350 XT and Filtek™ Bulk Fill - 3M resins, and that of resins photopolymerized with monowave and polywave LED lamps and halogen light. Thus, the types of light and lamp directly influence the compressive strengths of the composite resins.

摘要

目的

评估使用不同波长的发光二极管灯（多波长和单波长）进行聚合对纳米混合复合树脂Filtek™ Bulk Fill - 3M和3M™ Filtek™ Z350 XT抗压强度的影响。

材料与方法

本研究为前瞻性、实验性和对比性研究。样本由纳米混合复合树脂组成。样本量（n）为100个试件，分为10组。撰写本文时使用了CRIS（体外研究报告清单）指南。

结果

所有组之间存在统计学显著差异，P < 0.001。第2组（使用单波长发光二极管灯的3M™ Filtek™ Z350 XT纳米混合复合树脂块）显示出最高抗压强度，为238.36±34.69N；置信区间（213.55 - 263.18）N。其次是第④组（使用高功率多波长发光二极管灯的3M™ Filtek™ Z350 XT纳米混合复合树脂块）和第⑥组（使用软星多波长发光二极管灯的3M™ Filtek™ Z350 XT纳米混合复合树脂块），抗压强度分别为222.33 ± 53.09N和209.21 ± 22.52N。

结论

发现3M™ Filtek™ Z350 XT和Filtek™ Bulk Fill - 3M树脂的抗压强度之间，以及用单波长和多波长发光二极管灯及卤素灯光聚合的树脂抗压强度之间存在显著差异。因此，光和灯的类型直接影响复合树脂的抗压强度。
