The aim of this study was to compare the surface roughness and color stability of polyetheretherketone (PEEK) with those of conventional interim prosthetic materials like polymethylmethacrylate, bis-acrylic composite, and rubberized diurethane dimethacrylate, following immersion in solutions of varying pH value.
A total of 320 circular discs with 10 mm diameter and 2 mm height were divided based on the fabrication ( = 80)-group A: polymethylmethacrylate; group B: bis-acrylic composite; group R: rubberized diurethane; and group P: hot-pressed PEEK-and were subjected to baseline measurement of roughness ( = 40) and color ( = 40) using 3D profilometer and UV-Vis spectrophotometer, respectively. Later, 10 samples from each group were immersed in distilled water, black coffee, green tea, and Pepsi, respectively, for 120 days, and measurements of roughness and color were repeated. The differences in roughness (ΔR) and color change(ΔE) were calculated and statistically analyzed with a significance level of -value < 0.05.
Irrespective of the immersion solution, the highest mean difference in the roughness values was shown by rubberized diurethane specimens: ΔR = 3.574880 (0.0048350) in carbonated beverages, and lowest difference was shown by bis-acrylic composite: ΔR = 0.29004 (0.0017473) in distilled water. The greatest color stability was exhibited by PEEK. The type of interim material and immersion solution had a statistically significant effect on change in color and roughness values.
The immersion in solutions of varying pH had a significant effect on surface roughness and color stability of all the tested materials. The R value of all specimens after immersion was still within the clinically acceptable range. Polyetheretherketone was the most color stable material in all solutions, except in green tea.
This study will provide guidance to dentists and patients regarding the selection of interim material for long-term use, depending on the effect of beverage consumption on its color stability and roughness.

本研究旨在比较聚醚醚酮（PEEK）与传统临时修复材料（如聚甲基丙烯酸甲酯、双丙烯酸复合材料和橡胶化二甲基丙烯酸二urethane）在不同pH值溶液中浸泡后的表面粗糙度和颜色稳定性。
总共制备了320个直径10mm、高2mm的圆盘，根据制作材料分为4组（每组80个）：A组：聚甲基丙烯酸甲酯；B组：双丙烯酸复合材料；R组：橡胶化二甲基丙烯酸二urethane；P组：热压PEEK。分别使用3D轮廓仪和紫外可见分光光度计对每组中的40个样本进行粗糙度和颜色的基线测量。之后，每组各取10个样本分别浸泡在蒸馏水、黑咖啡、绿茶和百事可乐中120天，然后重复进行粗糙度和颜色测量。计算粗糙度差异（ΔR）和颜色变化（ΔE），并进行统计学分析，显著性水平设定为p值<0.05。
无论浸泡溶液如何，橡胶化二甲基丙烯酸二urethane样本的粗糙度值平均差异最大：在碳酸饮料中ΔR = 3.574880（0.0048350），而双丙烯酸复合材料样本的差异最小：在蒸馏水中ΔR = 0.29004（0.0017473）。PEEK表现出最大的颜色稳定性。临时材料的类型和浸泡溶液对颜色和粗糙度值的变化具有统计学显著影响。
浸泡在不同pH值的溶液中对所有测试材料的表面粗糙度和颜色稳定性有显著影响。所有样本浸泡后的R值仍在临床可接受范围内。除绿茶外，聚醚醚酮在所有溶液中是颜色最稳定的材料。
本研究将为牙医和患者在根据饮料消费对其颜色稳定性和粗糙度的影响来选择长期使用的临时材料方面提供指导。如何引用本文：Saraswathy A, Latha N, Ayyadanveettil P, 聚醚醚酮与传统临时修复材料表面粗糙度和颜色稳定性的比较评估：一项研究。《当代牙科实践杂志》2024；25（10）：930 - 935。
