The aim of this in-vitro study was to evaluate the effects of antacid gastric syrups on the surface roughness and microhardness of restorative dental materials.
Three different composite resins, nanohybrid, microhybrid and giomer, and four antacid gastric syrups were used in the study. A total of 150 samples were obtained by preparing 50 (10 mm x 2 mm) disk-shaped samples of each composite type. The composites were randomly divided into 5 subgroups and immersed in antacid syrups for 2 min every day for 28 days. The control group samples were kept in distilled water for 28 days. Surface roughness was measured at the beginning, on the 7th, 15th and 28th days using a mechanical profilometer, AFM, and SEM and microhardness was measured using a Vickers device. Shapiro-Wilk, Repeated Measures ANOVA, One-Way ANOVA, Tukey and Games-Howell tests were applied for statistical analysis.
After 28 days, the surface roughness of the giomer composite decreased significantly (p < 0.05). The surface roughness of microhybrid and nanohybrid composites increased slightly but not significantly (p > 0.05). Microhardness values of microhybrid and giomer composites showed a significant decrease (p < 0.05). SEM and AFM results were in agreement with the mechanical profilometer findings.
Agents such as calcium carbonate, sodium bicarbonate and magnesium carbonate in antacid gastric syrups can affect the surface properties of restorative dental materials. This may adversely affect the longevity and aesthetics of restorations.
The study emphasizes the need for caution in restorative material selection and care protocols in patients using antacid gastric syrups.
本体外研究旨在评估抗酸胃糖浆对牙科修复材料表面粗糙度和显微硬度的影响。
本研究使用了三种不同的复合树脂，即纳米混合树脂、微混合树脂和聚硅氧烷增强型玻璃离子复合体，以及四种抗酸胃糖浆。通过制备每种复合树脂类型的50个（10毫米×2毫米）圆盘形样品，共获得150个样品。将复合材料随机分为5个亚组，每天浸泡在抗酸糖浆中2分钟，持续28天。对照组样品在蒸馏水中保存28天。在开始时、第7天、第15天和第28天使用机械轮廓仪、原子力显微镜和扫描电子显微镜测量表面粗糙度，并使用维氏装置测量显微硬度。采用夏皮罗-威尔克检验、重复测量方差分析、单因素方差分析、图基检验和盖姆斯-豪厄尔检验进行统计分析。
28天后，聚硅氧烷增强型玻璃离子复合体复合材料的表面粗糙度显著降低（p < 0.05）。微混合树脂和纳米混合树脂复合材料的表面粗糙度略有增加，但不显著（p > 0.05）。微混合树脂和聚硅氧烷增强型玻璃离子复合体复合材料的显微硬度值显著降低（p < 0.05）。扫描电子显微镜和原子力显微镜的结果与机械轮廓仪的结果一致。
抗酸胃糖浆中的碳酸钙、碳酸氢钠和碳酸镁等成分会影响牙科修复材料的表面性能。这可能会对修复体的寿命和美观产生不利影响。
该研究强调了在为使用抗酸胃糖浆的患者选择修复材料和护理方案时需谨慎。
