摘要
背景:建议全口义齿佩戴者定期使用义齿清洁剂,以有效控制牙菌斑,这些清洁剂在一段时间内改变丙烯酸树脂的物理性质。因此,我们在体外研究了义齿清洁剂对热固化义齿基托树脂颜色稳定性的影响。目的:评价市售速效义齿清洁剂在不同时间间隔对热固化义齿基托树脂颜色稳定性的影响。材料和方法:36个热固化丙烯酸树脂(Ivoclar Triplex Hot-V)样品随机分为四组:A组(蒸馏水为对照);B组(麻醉- 3分钟);C组(固定范围+);D组(免染组),每组9个样品。记录基线值后,将标本浸泡在各自的清洁溶液中一段规定的时间间隔。每天重复这一过程,并在90天和180天后使用标准“Commission International de l’eclairage”颜色系统中的色度计评估颜色变化(ΔE)。统计分析采用配对t检验和Dunnett’s T3检验。结果:浸泡90天后,各组均呈现不同的颜色变化(ΔE)。然而,180天后,实验组之间存在显著的颜色差异(P = 0.001)。结论:浸泡180 D后,D组义齿基托树脂颜色变化最大,B、C、A组次之。各试验组ΔE值均随时间增加而升高。
Color Stability of Heat-cure Acrylic Resin Subjected to Simulated Short-term Immersion in Fast-acting Denture Cleansers.
Background: Regular usage of denture cleansers is recommended in complete denture wearers for effective plaque control, and these cleansers alter the physical properties of acrylic resin over a period of time. Thus, an in vitro study was carried out to assess the effect of denture cleansers on the color stability of heat-cure denture base resin.
Aim: The aim of the present study was to evaluate the effect of commercially available fast-acting denture cleansers on the color stability of heat-cure denture base resin at different time intervals.
Materials and methods: Thirty-six heat-cure acrylic resin (Ivoclar Triplex Hot-V) specimens are randomly allocated into four groups - Group A (distilled water as control); Group B (polident - 3 min); Group C (fixodent scope plus); and Group D (stain away plus) comprising of nine samples each. After recording the baseline values, the specimens were immersed in their respective cleansing solutions for a prescribed time interval. This procedure was repeated daily, and the color change (ΔE) was evaluated after 90 and 180 days interval using a colorimeter in a standard "Commission International de l'Eclairage" color system.
Statistical analysis used: Paired t-test and Dunnett's T3 test.
Results: All the groups exhibited a variable color change (ΔE) for an immersion period of 90 days. However, significant color differences (P = 0.001) were noticed among the test groups after 180 days.
Conclusion: The color change of denture base resin was greater for Group D followed by Groups B, C, and A respectively after 180 days of immersion. The ΔE values of all test groups increased with time.
