Objectives To assess the influence of cigarette smoke (CS) on the color and surface roughness of 3D printed, milled, and traditionally fabricated provisional crown and bridge (PC&B) materials. Materials and methods 112 disc-shaped samples were made employing four techniques and materials (28 per group) to fabricate PC&B prostheses. Specimens were fabricated using standard protocols, such as 3D printing, milling, conventional bis-acrylic resin, and traditional autopolymerizing polymethyl methacrylate (PMMA) resin. After preliminary color and surface roughness recording, each group specimen was divided randomly into two subgroups (14 each). The artificial saliva acted as the storage media for the control group specimens for 30 days, and test group specimens were subjected to CS in a customized smoking chamber (10 minutes twice daily, for 30 minutes). Final color and surface roughness measurements were made. The change in color (∆E00) and surface roughness (∆Sa) were calculated, and the data was tabulated for analysis. Statistical analysis One-way analysis of variance was used to analyze the change in color and surface roughness. Post-hoc Tukey HSD test was used for comparison between groups. Results The mean ΔE00 and ∆Sa were higher among groups exposed to CS than those exposed to artificial saliva. The maximum change in color was recorded in the autopolymerizing PMMA, whereas the 3D printed resins recorded the minimal change. The traditional bis-acrylic resin recorded the maximum mean surface roughness change, while the milled resin recorded the least change. Conclusions Within the study limitations, it can be inferred that when exposed to CS, 3D printed and milled PC&B materials have superior color stability and displayed less change in surface roughness when equated with traditional bis-acrylic and autopolymerizing PMMA resins.
目的 评估香烟烟雾（CS）对3D打印、铣削和传统制作的临时冠桥（PC&B）材料的颜色和表面粗糙度的影响。材料与方法 采用四种技术和材料制作了112个圆盘形样本（每组28个）以制作PC&B修复体。标本采用标准方案制作，如3D打印、铣削、传统双丙烯酸树脂和传统自凝聚甲基丙烯酸甲酯（PMMA）树脂。在初步记录颜色和表面粗糙度后，将每组标本随机分为两个亚组（每组14个）。人工唾液作为对照组标本的储存介质30天，试验组标本在定制的吸烟室中接受CS暴露（每天两次，每次10分钟，共30分钟）。进行最终的颜色和表面粗糙度测量。计算颜色变化（∆E00）和表面粗糙度变化（∆Sa），并将数据列表进行分析。统计分析 采用单因素方差分析来分析颜色和表面粗糙度的变化。采用事后Tukey HSD检验进行组间比较。结果 暴露于CS的组中，平均∆E00和∆Sa高于暴露于人工唾液的组。自凝PMMA记录的颜色变化最大，而3D打印树脂记录的变化最小。传统双丙烯酸树脂记录的平均表面粗糙度变化最大，而铣削树脂记录的变化最小。结论 在研究局限性范围内，可以推断，当暴露于CS时，与传统双丙烯酸树脂和自凝PMMA树脂相比，3D打印和铣削的PC&B材料具有更好的颜色稳定性，并且表面粗糙度变化较小。
