摘要

【摘要】目的研究静磁场对正畸粘接剂聚合反应的影响。虽然目前还没有研究SMF对剪切粘接强度(SBS)和粘接残余指数(ARI)的影响,但本研究旨在探讨SMF在正畸复合材料上的储存对SBS和ARI的影响。材料与方法本研究采用Biofix和Heliosit正畸粘接剂,拔牙前磨牙60颗,按粘接剂类型分为两组。每一组又根据存储场磁场强度分别为0、225和1000高斯分为3个子组(每10个子组)。在37℃的暗湿环境中孵育24 h后,用拉力机进行支架脱粘。体视显微镜观察ARI,放大倍数为20倍。SBS和ARI数据分别采用方差分析和Kruskal-Wallis检验进行分析。P值设为0.05。结果Heliosit胶粘剂SBS在8.5496、9.7592和11.2129 mpa时随场强的升高而显著升高,而Biofix胶粘剂SBS在0、225和1000Gauss场强下分别在9.1547、11.8294和8.7132 mpa时变化显著。在3种贮藏强度下,Biofix和Heliosit的ARI差异不显著,p值分别为0.543、0.377。结论bibiofix和Heliosit正畸粘接剂在225Gauss SMF中储存可改善SBS。此外,SMF强度增加到1000Gauss时,Heliosit SBS得到改善,而Biofix则有明显的降低。关键词:磁场聚合剪切键强度静磁场粘接残余指数致谢作者感谢摩苏尔大学对本研究的支持。披露声明作者未报告潜在的利益冲突。sssa对概念化,方法,调查,写作-原稿准备,审查和编辑做出了贡献。MKA和NRA贡献了方法论,调查,和写作-审查和编辑。摩苏尔大学(牙科学院)研究伦理委员会确保研究计划符合赫尔辛基(no. 5)的伦理原则。152dum)于2022年25\4\发布。补充数据本文的补充数据可以在线访问https://doi.org/10.1080/27705781.2023.2265262

Estimation of the shear bond strength and adhesive remnant index of orthodontic adhesives stored in static magnetic field
ABSTRACTPurpose Static magnetic field (SMF) affects the polymerization reaction of orthodontic adhesives. Although their effects on shear bond strength (SBS) and adhesive remnant index (ARI) are not investigated yet, the current research designed to search the impact of storage of the orthodontic composite on SMF on SBS and ARI.Materials and Methods Biofix and Heliosit orthodontic adhesives were employed in this study, beside 60 extracted premolars that were separated into two equal groups according to adhesive type. Each group, furtherly, is divided into three subgroups (10 each) according to the storage field magnetic intensity as Zero, 225 and 1000Gauss. The tensile instron machine was performed to debond the brackets after incubation for 24 h in a dark wet environment at 37C°. ARI was evaluated by stereomicroscope at 20 magnification power. SBS and ARI data were analysed by ANOVA and Kruskal–Wallis tests, respectively. P was set at 0.05.The results SBS of Heliosit adhesive significantly increased with elevation of field intensity at 8.5496, 9.7592 and 11.2129MPas, while Biofix SBS was significantly changed from 9.1547, 11.8294 and 8.7132MPas with Zero, 225 and 1000Gauss field intensity, respectively. ARI showed a non-significant difference at three storage intensities as p = 0.543, 0.377 for Biofix and Heliosit, respectively.Conclusion Storage of Biofix and Heliosit orthodontic adhesives in 225Gauss SMF improves SBS. Furthermore, an increase in SMF intensity up to 1000Gauss improves Heliosit SBS, unlike Biofix which shows significant reduction.KEYWORDS: Polymerization in magnetic fieldshear bond strengthstatic magnetic fieldadhesive remnant index AcknowledgmentsThe authors thank the University of Mosul for their support in conducting this research.Disclosure statementNo potential conflict of interest was reported by the author(s).Author contributionsSSA contributed to conceptualization, methodology, investigation, writing – original draft preparation, reviewing and editing.
