Abstract

Physical and mechanical properties of high-viscosity bulk-fill resin composites submitted to additional polymerization for semi-direct use were evaluated. Filtek Z350 XT, Aura Bulk Fill, Beautifil Bulk Restorative, Filtek One Bulk Fill Restorative, and Tetric N-Ceram Bulk Fill were submitted to additional polymerization to evaluate sorption, solubility, surface microhardness, surface roughness before and after simulated brushing, color stability after coffee staining, flexural strength, elastic modulus, and modulus of resilience. Filtek Z350 XT and Filtek One Bulk Fill Restorative showed higher sorption values, while Aura Bulk Fill showed higher solubility (p<0.0001). Microhardness values were significantly higher for Filtek Z350 XT (p<0.0001). Roughness increased after wear for all resins (p<0.05). All resins exhibited staining, with significantly higher ΔEab, ΔE00, and ΔWID values observed for Beautifil Bulk Restorative (p<0.0001). Flexural strength values were higher for Filtek Z350 XT and Filtek One Bulk Fill Restorative in comparison with the others (p<0.0001). Filtek One Bulk-Fill had higher elastic modulus and modulus of resilience values (p<0.0001). Physical and mechanical properties varied according to the composition. None of the bulk-fill resins showed surface microhardness and roughness properties after brushing similar to or superior to those of the conventional type. Color stability after staining depended on resin composition, with Beautifil Bulk Restorative showing more intense staining.

在半直接修复中使用的经过额外聚合的块状填充树脂复合材料的物理和机械性能。

对半直接使用的高粘度团状填充树脂复合材料的物理和机械性能进行了评估。对 Filtek Z350 XT、Aura Bulk Fill、Beautifil Bulk Restorative、Filtek One Bulk Fill Restorative 和 Tetric N-Ceram Bulk Fill 进行了额外聚合，以评估吸附性、溶解性、表面微硬度、模拟刷洗前后的表面粗糙度、咖啡染色后的颜色稳定性、弯曲强度、弹性模量和回弹模量。Filtek Z350 XT 和 Filtek One Bulk Fill Restorative 显示出更高的吸附值，而 Aura Bulk Fill 显示出更高的溶解度（p＜0.05）。

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
