摘要

目的:利用AutoCAD软件,采用常规后牙复合树脂、大块填充复合树脂和高粘度玻璃离子水门合剂(HVGIC)对I类修复体恒磨牙的微渗漏进行研究。方法:选择33颗无龋第三磨牙。制备了I类空腔。将牙随机分为3组,每组11颗牙,分别为:A组(Filtek Z550)、B组(Filtek块状填充后牙体)、C组(EQUIA Fil)。所有标本在37℃蒸馏水中保存24 h。牙齿在5±2℃至55±2℃的温度下热循环1000次,然后浸泡在0.5%碱性紫红中24小时。在配备数码相机的体视显微镜下拍摄每颗牙齿的两个中远端切口。测定染料浸润表面积。结果:采用单因素方差分析(ANOVA)进行统计学评价。单因素方差分析显示,三组间微渗漏无显著差异(P = 0.07)。而C组(EQUIA Fil)的微漏率最低。所有测试材料的结果相似,但EQUIA Fil (C组)的微漏率最低。结论:本研究中,尽管EQUIA Fil的微漏率最低,但测试材料并不能完全消除微漏。本文引用方式:Çelenk S, ataku O, Ayna B, g nay a .两种不同后部复合材料和高粘度玻璃离子水门体的微泄漏:体外研究。国际医学杂志,2016;12(1):34- 38。https://doi.org/10.5577/intdentres.2022.vol12.no1.6语言修改:本手稿中的英语已由至少两名专业编辑检查,他们都是英语母语者。

Microleakage of two different posterior composites and a high-viscosity glass-ionomer cement: An in vitro study
Aim: Using AutoCAD, we examined the microleakage of permanent molars in Class I restorations using a conventional posterior composite resin, a bulk-fill composite resin, and a high-viscosity glass-ionomer cement (HVGIC). Methodology: In total, 33 extracted noncarious third molars were used. Class I cavities were prepared. The teeth were randomly divided into three groups of 11 teeth each, as follows: Group A (Filtek Z550), Group B (Filtek Bulk-Fill Posterior Restorative), and Group C (EQUIA Fil). All specimens were stored for 24 h at 37 °C in distilled water. The teeth were thermocycled 1,000 times between 5 ± 2°C and 55 ± 2°C prior to immersion in 0.5% basic fuchsin for 24 h. Two mesiodistal cuts of each tooth were photographed under a stereomicroscope equipped with a digital camera. The dye-infiltrated surface area was measured. Results: Statistical evaluations were performed by one-way analysis of variance [ANOVA]. One-way ANOVA showed no significant difference between the three groups in microleakage (P = 0.07). However, the lowest microleakage ratio was seen in Group C (EQUIA Fil).  Similar results were obtained with all tested materials, but the lowest microleakage rate was obtained with EQUIA Fil (Group C). Conclusion: In this study, the tested materials were not completely successful in eliminating microleakage, although the lowest microleakage rate was obtained with EQUIA Fil.   How to cite this article: Çelenk S, Ataş O, Ayna B, Günay A.
