Abstract

Abstract Aim: This study examined the bond strength associated with Denteshield® Primer as a replacement for a conventional, non-antimicrobial, orthodontic primer. Materials/methods: Sixty human premolar teeth were divided into three groups (n=20). Each group was assigned to receive either Denteshield®, Pro Seal® or Transbond XT TM primer. Light-cured Transbond XTTM adhesive resin was utilised to bond a bracket to each sample tooth following the application of the assigned primer. Ten samples from each group were tested for shear bond strength using a universal testing machine. The remaining 10 samples from each group underwent bracket debonding using a debonding plier. Applying an adhesive remnant index, each sample was scored under a microscope at 2.5× magnification. The data were analysed using One-way ANOVA, the Tukey post hoc test and the Kruskal–Wallis test. Results: The mean shear bond strength (MPa) of the three groups was: Denteshield® (33.18 ± 13.56), Pro Seal® (23.68 ± 12.04) and Transbond XTTM primer (26.19 ± 9.44). There was no significant difference in the shear bond strength across all three groups (p = 0.19). The adhesive remnant index results also showed no significant differences between the three groups (p = 0.278). Conclusion: Based on the shear bond strengths obtained in this study and the previously reported values necessary for clinical use, all three primers appear adequate for clinical use.

使用抗菌引物Denteshield®提高正畸托槽的粘结强度

摘要目的:本研究考察了Denteshield®Primer作为传统的、非抗菌的正畸引物的替代品的结合强度。材料/方法:60颗人前磨牙分为3组(n=20)。每组分别接受Denteshield®、Pro Seal®或Transbond XT TM引物。使用光固化的Transbond XTTM粘接树脂将托架粘接到每个样品牙齿上，然后使用指定的底漆。每组各取10个样品，使用万能试验机进行剪切粘结强度测试。每组其余10个样本使用脱粘钳对支架进行脱粘。在2.5倍放大镜下，应用黏合剂残余指数对每个样品进行评分。采用单因素方差分析、Tukey事后检验和Kruskal-Wallis检验对数据进行分析。结果:三组引物的平均剪切结合强度(MPa)分别为:Denteshield®(33.18±13.56)、Pro Seal®(23.68±12.04)和Transbond XTTM引物(26.19±9.44)。三组间剪切粘接强度差异无统计学意义(p = 0.19)。粘接剂残留指数在三组间差异无统计学意义(p = 0.278)。结论:根据本研究获得的剪切结合强度和先前报道的临床使用所需值，所有三种引物都适合临床使用。(中华骨科杂志，2022;[39]: 49 - 54。DOI: 10.2478 / aoj - 2023 - 0009)

期刊介绍： The Australasian Orthodontic Journal (AOJ) is the official scientific publication of the Australian Society of Orthodontists. Previously titled the Australian Orthodontic Journal, the name of the publication was changed in 2017 to provide the region with additional representation because of a substantial increase in the number of submitted overseas'' manuscripts. The volume and issue numbers continue in sequence and only the ISSN numbers have been updated. The AOJ publishes original research papers, clinical reports, book reviews, abstracts from other journals, and other material which is of interest to orthodontists and is in the interest of their continuing education. It is published twice a year in November and May. The AOJ is indexed and abstracted by Science Citation Index Expanded (SciSearch) and Journal Citation Reports/Science Edition.
